“This is the first detailed view of the U. S. Air Force’s Northrop T-38 Supersonic light weight jet trainer now under development by the Northrop Division of Northrop Aircraft, Inc., at Hawthorne, California. Shown in formation flight in this artist’s conception are three of the twin jet T-38’s. The latest member of the family of advance aircraft produced by Northrop for the Armed Services, the T-38 fills the need for a trainer aircraft with a performance capability matching the characteristics of supersonic operational aircraft. Student and instructor are seated in tandem cockpits. The raised seat in the rear cockpit enables the instructor to check the student’s movements and reactions. Indicating the supersonic capabilities of the T-38 is the “coke bottle” or area rule configuration of the fuselage. Crisp, clean lines of the T-38 reflect an advanced new design concept used by the Northrop engineering team to achieve optimum performance through light-weight and simplicity. The high performance characteristics of the T-38 have been combined with low initial and maintenance costs and the ability to operate from short runways.”
Hawthorne...isn't that where SpaceX mission control is located?

An eye-popping AND eye-opening image.
First:
I’ve loved the look of this aircraft since childhood. To me, it’s timeless, classic and still sexy. I had no idea it’s been around since 1957!
I understand, the T-38 is old, but so is the B-52. Being nowhere near as aesthetically appealing, along with Boeing being on my shit list, I find the following statement to be somewhat blasphemous:
“In September of 2018, [the] USAF announced the replacement of the Talon by the Boeing T-7 Red Hawk with phaseout to begin in 2023.”

Lockheed Martin F-22 "Raptor's" assigned to the 90th Fighter Squadron, Joint Base Elmendorf-Richardson, Alaska, taxi to their parking location at the Royal Australian Air Force Base Amberley flightline for 'Exercise Talisman Sabre 19', July 9. TS19 provides effective and intense training to ensure U.S. Forces are combat ready, capable, interoperable, and deployable on short notice.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22s airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named Senior Sky, this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 Flanker- and MiG-29 Fulcrum-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35s delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35s strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22s price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G Growler. Issues with the F-22s reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35s capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP). A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D. To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35s.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22s thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22s high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22s thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22s aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22s exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22s mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22s stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.

Not an excellent photo, but just wanted to highlight the capabilities of this amazing fire fighting machine which is being mothballed due to poilitics. The terrible wildfires in the USA could be controlled much better and quicker if the local authorities would hire this waterbomber, which proved itself in Lake Elsinore Calif. a couple of years ago. Here in Port Alberni BC we love the waterbombers , know what efficient fire fighting tools they are, and can't understand how politics can take them out of the skies. So much money and new technology has been poured into them over the past decade that they have years of use still and could be one of the most important fire fighting tools anywhere in the world! I have no personal stock in this company, just hoping someone will read this and pass the info on if you live in an area where fires are a problem. SAVE THE WATERBOMBERS, SAVE YOUR HOMES AND FORESTS.
Here are some stats: the only operator worldwide to operate Sikorsky S61 Type 1 helicopters and the world’s largest water bombers. Since purchasing the Mars water bombers, significant upgrades have been carried out on the Hawaii Mars to bring it to higher aviation and safety standards for modern-day firefighting. The "Next Generation" Hawaii Mars has an EFIS Glass Cockpit and the ability to stream live data from certain key on-board, indication systems. Other forms of data that are available from the aircraft in real time are Flight Tracking, Load Data measuring, Aircraft Performance statistics, Atmospheric Condition at Drop readings, and Accurate Drop Location reporting. Mars carries 600 US gallons (2,270 litres) of foam concentrate - enough for 21 drops of a 0.4% solution which is the standard used although it may be decided to use more or less foam as dictated by the Incident Commander. The Mars are also equipped to deliver Thermo-Gel which when mixed with water forms a light gel by encapsulating the water droplets. This product provides a more even coating of the fuels as well as lasting longer on the ground.

Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35s delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35s strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22s price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G Growler. Issues with the F-22s reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35s capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP). A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D. To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35s.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22s thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22s high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22s thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22s aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22s exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22s mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22s stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.
I am aware of the capabilities of Time-Zero and just how amazing it can be under various lighting conditions, etc., but here the Time-Zero & SX-70 combination surpassed even my expectations... I hate wasting shots! This time, the conditions were right, and I ended up with the luxurious result of wide aperture, soft light, delicate color, and a depth of field that made the peony in this shot appear to be almost painted, as if it were an old botanical watercolor. Hope you enjoy.
Grand Canyon is a large multipurpose offshore construction vessel (OSV) capable of performing a variety of subsea activities such as jet trenching and heavy soil trenching. The high manoeuvrability and station keeping capabilities of the vessel allow it to operate even in adverse climatic conditions.
Norwegian ship-builder Bergen Group received the order for construction of the Grand Canyon from Volstad Maritime in December 2010. The keel of the vessel was laid in August 2011. The construction was carried out at Fosen in Rissa, Sør-Trøndelag.
The hull of the vessel was manufactured by Tersan Shipyard in Turkey.
The hull was launched in January 2012 in the presence of the Norwegian Prime Minister, Jens Stoltenberg. It was then towed to Bergen Group's shipyard in Norway for final outfitting.
Grand Canyon was delivered in November 2012 having completed sea trials in October. The new build was financed by three Norwegian finance groups - Garanti-instituttet for eksportkreditt (GIEK), Export Credit Norway (Eksportkreditt) and SpareBank 1 SMN.
The vessel is currently on a five-year charter with Canyon Offshore, a company owned by Helix Energy Solutions Group.
Features of Volstad's new offshore construction vessel
Grand Canyon is built according to the ST 259 CD design developed by the Norwegian ship designer Skipsteknisk. The vessel carries DNV's 'Clean Design' notation for its eco-friendly operation.
The vessel boasts a dynamic positioning (DP) Class-3 control system for automatic positioning and heading. She can be deployed for use in shallower depths because of her modest draught.
In order to carry out subsea installation, burial support operations and general offshore construction work, the vessel is provided with a working platform that is stable and has a large capacity. Jet trenching can be performed from the ship's forward port side, while soil trenching can be carried out from the aft of the vessel.
The vessel features two indoor remotely operated vehicle (ROV) hangars, which can be prepared for the deployment of up to five work-class ROVs (WROV). The ROVs can be deployed to a depth of 3,000m.
A carousel reel-drive system is installed below the ship's deck which is able to lay power cables, pipelines and umbilicals into the trench at the seabed. Once placed, these cables or pipelines can be buried below the surface of the sea to a depth of up to 9m with the help of the ROVs.
The under-deck has enough strength to bear the load of heavy equipment, which allows the crew to finish mobilisation and demobilisation operations in shorter times.
Main dimensions and accommodation
The dead weight of the vessel is 7,000t, while gross and net tonnages are 12,652t and 3,796t respectively. She has an overall length of 127.75m, a moulded breadth of 25m and scantling draught of 7.5m. The length between perpendiculars is 114.6m, and the deck area is 1,650m².
The Grand Canyon accommodates up to 104 people in single and double cabins. Facilities onboard the vessel include a meeting room, internet café, reception, sauna, gym, coffee house and hospital.
The vessel is equipped with two cranes, including an active heave compensated (AHC) offshore crane, the MacGregor HMC 4240. The crane has a safe working load of 250t at 10m outreach capacity. The second crane is the MacGregor HMC 2201 model and can lift 15t at 20m outreach.
Grand Canyon is powered by a diesel-electric propulsion system. The ship is fitted with six six-cylinder Wärtsilä 32 main engines. Each engine generates 2,880kW of power at 720rpm and drives a NES generator (NEGR 710 LB10 model) rated at 3,450kVA. In addition, there is a nine-cylinder Wärtsilä 20 emergency generator of 1,665kW capacity and a Mitsubishi S6R-MTPA harbour generator of 595kW capacity.
Propulsion is provided by two electric motors of 2,500kW each. Side thrusters comprise six Wärtsilä tunnel thrusters, each with 2,000kW of power. Four of the thrusters are mounted forward and the other two are mounted aft.
A U.S. Air Force Lockheed Martin F-22 Raptor flies above Royal Australian Air Force Base Tindal, Australia, March 2, 2017. Twelve Lockheed Martin F-22 Raptors and approximately 200 U.S. Air Force Airmen participated in the first Enhanced Air Cooperation, an initiative under the Force Posture Agreement between the U.S. and Australia.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 Flanker- and MiG-29 Fulcrum-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35's delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35's strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22's price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G Growler. Issues with the F-22's reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35's capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP). A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D. To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35's.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22's thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22's high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22's thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22's aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22's exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22's mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.

Twelve Lockheed Martin F-22 "Raptors" and approximately 200 U.S. Air Force Airmen participated in the first Enhanced Air Cooperation, an initiative under the Force Posture Agreement between the U.S. and Australia.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 Flanker- and MiG-29 Fulcrum-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export.

The F-22's aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22's exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22's mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.
A couple of months ago, I started feeling that perhaps it wouldn’t be beyond my emotional capabilities to at least start discussing adopting another cat. I threw the idea out to Carol to see what she thought. She wasn’t what you would call enthusiastic about it, but she was willing to consider it, perhaps, after she was finished with the month of catsitting she was doing for our neighbor. We’ve had a reciprocal catsitting arrangement with our neighbor for a long time, a comfort to us both knowing that our beloved animals will be well taken care of in our absence. Lately, of course, it had been a bit one-sided, since we were catless, but we were still willing to help and it’s always a good idea to build up a bit of karmic credit when you can.
So, there it was, the idea of having another cat, percolating around in our thoughts. We couldn’t help but mention it to friends and co-workers. We couldn’t help but push that idea out into the universe. I started getting e-mails from people with cats available for adoption, so did Carol. We had created a vacuum in our own little universe and the larger universe was on the move to fill that void. There was now a cat out there with our name on it, moving in our direction, barreling down the cosmic highway toward our hearts. Wishes are very powerful things, you know.

**************************************
Months from now, if people stumble onto this set of Flickr photos, they won't know or care when the photos were actually taken. After all, rain is a fairly universal phenomenon, and it can happen in any of the four seasons of the year.
Still, it's an odd experience to be writing these notes a week after the photographs were taken -- at an altitude of 35,000 feet, on a flight to Miami that lifted off from JFK airport just as the first snow flurries hit the runway at the beginning of what promises to be the first major snowfall of the 2009 season. Twelve inches of snow are expected by the time the storm stops, which makes this collection of water-soaked individuals seem like they got stuck in the wrong place and the wrong time.
But a week ago, the temperature was about ten degrees warmer -- and what could easily have been a foot or two of snow was instead just a couple of inches of cold rain. Rain, of course, brings out the umbrellas; and on a couple of earlier occasions this year (which you can see here and here on Flickr), I began to see that -- notwithstanding the typical stories about New York fashions -- people were not restricting themselves to black raincoats and black umbrellas. My winter coat (courtesy of North Face) is black, and just about every umbrella I've ever owned has been black; my suitcases are black, my backpacks and briefcases have always been black, and even my camera bag is black. Since it's promising to be a cold winter, I just bought a new pair of gloves and a new woolen cap ... in black.
But that's apparently not true for many other New Yorkers. While you'll see a few black outfits in the photos collected here, the range of vivid colors continues to surprise me. Somehow, it's something you would expect to see at the beginning of the spring season -- signifying the rejection of the dark gloom of clouds and rain, and celebrating the imminent arrival of flowers and blossoms, of emerald-colored trees and thick green grass and the chirping of birds. But this collection of photos was taken in mid-December, only a week before the official beginning of winter. You'd think that people would be carrying black umbrellas and somber raincoats that marked the season of death and darkness, but I guess that's just not the way things are here in New York City.
On the previous occasions when I've photographed umbrellas in the rain, I've deliberately used a "pocket camera," albeit a fairly sophisticated one such as the Canon G-10. I wanted something that would be compact enough that I could stick into my jacket pocket if the rain got heavy, and I didn't want to risk damaging the electronic components a really expensive, sophisticated camera by getting it wet. The results were usually fairly good, but I always wondered if I could do a better job with one of my high-end DSLR cameras...
... so that's what I used for this collection of photos: my Nikon D700 camera, with a big, heavy 70-300mm zoom lens. I attached a lens hood to the lens, to minimize the chances of raindrops falling directly onto the lens itself; and I stood beneath the awning and overhang of various storefronts and buildings along Broadway as the rain poured down steadily all around me. Next time, I might be even more adventurous, since I've got a professional waterproof bag-thingy that should keep the camera dry even if I'm standing out in the middle of a torrential downpour. But for now, this was a good start.
Because of the rain, most of the people I photographed paid no attention to me at all; they were too busy concentrating on where they were walking, where the puddles were deepest, and whose umbrellas were about to poke them in the face. On the rare occasions when they did see a crazy guy standing under an awning, pointing a camera in their general direction, they frowned or gave me a quizzical look, and just kept going...
So that's the way it was, on this rainy Sunday afternoon. At this point, I'm going to assume that winter has officially arrived, and that the precipitation during the next few months will take the form of snow, not rain. I don't know how well it will turn out, but one of my future projects will be a series of photos during a blizzard. Stay tuned ... and in the meantime, stay dry.

Back to color - working on new photo processing software - was not completely happy with what I was using... Hopefully this one does the charm. Tools really make a difference! Testing its capabilities for the time being. (Trying out Photomatix, one shot and progress to multi-shot HDR. Can you tell me what your favorite software tools are for popping out the natural color?)

Cheesy story-line:
Although slight less maneuverable than the Razor, the Wasp's speed capabilities far surpass those of most fighters of it's size. Heavy armor plating protects the engine from all but a, near direct, rear shot. The original version was much sleeker in appearance, but with the modifications made, some paneling had to be removed completely exposing the inner workings. With it's sensor clusters and missile array, the Wasp is able to strike targets at great distances. Forward twin burst cannons make it a threat at close distances as well. Being nearly invulnerable to all but rear attacks, the Wasp had a long run in production. It wasn't until the introduction of a new engine did the bulky-fighter lose it's place in battle.
Build notes:
I normally don't go for tail sections like this, I was just joking around when I decided I liked it enough to go with it. I'll work on a better pic, but in real life the 3/4 angle view gives the appearance that the tail curves down slightly due to the way the yellow stripe is attached.
I used some of the cockpit and the front pylons from the Goose for this. I think it might have started a new trend in my building where I take a section(s) from one MOC and carry it to the next, forming a string, MOC to MOC.

Pentagon leaders often speak of the need for disruptive technologies in the Fleet to mitigate the risks of shrinking defense budgets, declining U.S. military technological superiority and improving adversary capabilities. Last week, a remarkable example of disruptive innovation occurred. How did the Navy react? It simply reaffirmed its unimaginative plan to send its carrier-launched drone to the boneyard—and potentially sentence the aircraft carrier to a similar fate.
The Navy’s test carrier drone, the X-47B UCAS-D (Unmanned Combat Air System Demonstrator), recently participated in the first-ever fully autonomous aerial refueling at Naval Air Station Patuxent River. Though the implications of this engineering feat are wide-ranging and not wholly known at this point, successful demonstration of unmanned aerial refueling does shed light on several ongoing arguments about the future of U.S. military aviation.
First, the success of X-47B in breaking engineering barriers supports the expansion of unmanned aviation both within the carrier air wing and throughout the military as a whole. This is an autonomous aircraft as opposed to remotely piloted, and it just completed one of the most difficult tasks to perform with another aircraft through refueling. The Department of Defense has been working on developing a stabilized drogue to enable more reliable aerial refueling, but the X-47B did not even use this new system. Rather, the autonomous aircraft did all the work itself, demonstrating incredible feedback sensitivity.
Perhaps the reason there is not more fanfare or appreciation for the leap ahead in technological advancement is because the successful demonstration of autonomous aerial refueling, for some, supports an argument for replacing more F-35 Joint Strike Fighter carrier variants with X-47B-like platforms. There is a suggestion that such a progression would put the Navy’s sixth-generation fighter (F/A-XX) in jeopardy, a program which enjoys considerable support within the naval tactical aviation community. In this budgetary environment, relying on proven technologies—like those in the X-47B program—is a far better bet than the imagined, untested technologies in the yet-to-begin F/A-XX program.
Further, Pentagon leaders are fighting with Congress—specifically Chairmen John McCain, Mac Thornberry, and Randy Forbes—about what those unmanned combat aircraft should do in a program called the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS). Should the UCLASS merely serve as the eyes and ears of the aircraft carrier with limited strike capability in only non-contested environments, or should it be capable of striking enemies through their denied zones?
Last week, Secretary of the Navy Ray Mabus weighed in, commenting bluntly that the F-35C “almost certainly will be the last manned strike fighter aircraft the Department of the Navy will ever buy or fly.” This would seem to signal his strong support for the transition to unmanned platforms, especially for deep penetrating strike missions. Coincidentally (or not), Secretary Mabus last week also created two new civilian and military positions to focus solely on unmanned systems within the Navy to recognize the untapped potential of these types of platforms.
The UCAS-D’s successful autonomous refueling means that its impressive range of 2,400 miles can now be extended by tanker, thus allowing the carrier drone to carry vastly more ordnance. Already the X-47B carries about 85 percent of the payload of a F-35 Joint Strike Fighter—and carries it three times further. Even if tankers must turn around at 600 miles from the outer edge of an adversary’s denied zone, this breakthrough capability gives the X-47B enough “legs” to deliver true firepower anywhere US commanders want, especially if the ordnance delivered is capable of extended range flight of its own.
Without a refuelable UCLASS in the future carrier air wing, the Navy might as well take the “strike” out of carrier strike group. A key value of an aircraft carrier is its ability to accept new planes when the character of warfare changes, something it has done remarkably well for over seven decades. That change is happening now, and failure to procure a strike version of the UCLASS renders the Navy’s investment in new aircraft carriers far less cost-effective.
Outside of the carrier air wing, autonomous aerial refueling could result in several other force employment changes. For instance, the Marine Corps is currently putting the finishing touches on its program to develop a tanker variant of the V-22 Osprey. Combining tanker Ospreys with refuelable low-end land-based drones could result in much-improved reconnaissance abilities for the austere Special-Purpose Marine Air-Ground Task Forces that have become a staple of American forward presence. The Army has already developed a manned-unmanned teaming system for its Apache helicopters to control drones. Tanker V-22s could implement a version of the same to control and refuel fleets of unmanned aircraft and achieve true persistent surveillance. Even within the Navy—which will soon have V-22s onboard carriers to deliver supplies—the possibilities are enticing and need to be explored further through testing and experimentation.
These are only a small subset of the possibilities that opened up over the skies of Pax River last weekend. To fully exploit such disruptive technology, the Department of Defense should open access to the UCAS-D program to aviators from every service. Despite a long record of achievement, the Navy still maintains that it will shut down the UCAS-D program and send the X-47B to the aircraft boneyard in Arizona with less than a quarter of its rated flight hours used up. This is a true waste. As we suggested in 2013, the Navy should reconsider this policy and allow creative military thinkers to continue experimental testing of the two planes beyond fiscal year 2016.
The rhetoric of Secretary Mabus points the Navy in the right direction for the future. Now, he must follow through with action. Extending the UCAS-D test program and refining UCLASS requirements toward a high-end strike aircraft would cement Mabus’ legacy and truly put the Navy on the path to continued dominance in the future.

Lockheed Martin F-22 Raptor's assigned to the 90th Fighter Squadron, Joint Base Elmendorf-Richardson, Alaska, taxi to their parking location at the Royal Australian Air Force Base Amberley flightline for 'Exercise Talisman Sabre 19', July 9. TS19 provides effective and intense training to ensure U.S. Forces are combat ready, capable, interoperable, and deployable on short notice.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22s airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named Senior Sky, this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 Flanker- and MiG-29 Fulcrum-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35s delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35s strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22s price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G Growler. Issues with the F-22s reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35s capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP). A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D. To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35s.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22s thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22s high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22s thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22s aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22s exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22s mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22s stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.
By definition the Aberuk is considered a hover-tank, however it has spaceflight capabilities too and can enter atmospheres on its own.
The Aberuk was the Marauder's (a highly advanced AI race) tank. After they were defeated and were taken control, their units are now used by the Council as they are still really powerful vehicles.
Its 2 high-energy Warp cannons on ball mounts provides enough firepower to bring down any tank, while the cyclonic shields (thus the unusual circle shape) protect it from any projectile. However, if the shields are penetrated its armor can still take some hits.
The secondary weaponry is 4 dual turrets, with similar firepower as an HMG.
The high mobility (sidestrafing, air and spaceflight capability) combined with the firepower and powerful shielding made the Aberuk dreaded during the war. Now with them on our side, the enemies shall fear them.

A couple of years ago I decided I would take up photography so I bought you first camera.... a Fujifilm HS30 bridge camera. After using it for a while, I sort of outgrew it and invested in my first DSLR, a Nikon D3400. I started out like many people do….taking photos of flowers, sunsets, landscapes etc. What I really wanted to do was take photos of people, but I never really had the confidence to work with someone 1 on 1.
When I saw the Cardiff Shooters advertising a portrait shoot with models at Insole Court I thought “why not?” so I went along to see what it was all about but more so to challenge myself and get out of my comfort zone. I believe I am now finding my niche. I am now a lot more confident shooting photos of people and I’m getting so much out of it. I also really love low light and astro. What I enjoy most about photography is that I learn something new each time I pick up my camera and it stretches my capabilities and allows me to be creative. I take a lot of inspiration from the photographers I have met in the last couple of years and I have met some amazing people whilst doing something I love. Photography makes me and other people happy. What more could you want?
Designed in 1933 by Anders Anderson, a Swedish engineer working for Bücker Flugzeubau in Berlin. The prototype flew in April 1934 and was immediately ordered in large numbers as an ab-initio trainer for the Luftwaffe. An estimated 4,000 planes were built, first in Germany and then under licence in Switzerland, Spain, Czechoslovakia, Hungary and Japan. Used as aerobatic trainers by the Spanish Air Force up to the late 70’s, they were in continuous production in Spain for longer than in any other country. Originally powered by a Hirth engine of 80hp and later 105hp, it performed well despite its low power due to its extreme lightness. The Jungmann is of mixed construction with a basic fuselage structure of chrome-molybdenum tube, an expensive but highly tensile metal. The wings, which weigh only 24 lbs each, are made out of wood with fabric covering. This example weighs 1000 lbs empty, nearly 300 lbs less than a Tiger Moth. Both the Jungmann and her single-seater sister, the Jungmeister, have always been renowned for their aerobatic capabilities due to a strong structure, 4 ailerons, and excellent flick-rolling capabilities.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The OV-10 Bronco was initially conceived in the early 1960s through an informal collaboration between W. H. Beckett and Colonel K. P. Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.
The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.
Beckett and Rice developed a basic platform meeting these requirements, then attempted to build a fiberglass prototype in a garage. The effort produced enthusiastic supporters and an informal pamphlet describing the concept. W. H. Beckett, who had retired from the Marine Corps, went to work at North American Aviation to sell the aircraft.
The aircraft's design supported effective operations from forward bases. The OV-10 had a central nacelle containing a crew of two in tandem and space for cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connected them at the fin tips. The OV-10 could perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.
The aircraft had responsive handling and could fly for up to 5½ hours with external fuel tanks. The cockpit had extremely good visibility for both pilot and co-pilot, provided by a wrap-around "greenhouse" that was wider than the fuselage. North American Rockwell custom ejection seats were standard, with many successful ejections during service. With the second seat removed, the OV-10 could carry 3,200 pounds (1,500 kg) of cargo, five paratroopers, or two litter patients and an attendant. Empty weight was 6,969 pounds (3,161 kg). Normal operating fueled weight with two crew was 9,908 pounds (4,494 kg). Maximum takeoff weight was 14,446 pounds (6,553 kg).
The bottom of the fuselage bore sponsons or "stub wings" that improved flight performance by decreasing aerodynamic drag underneath the fuselage. Normally, four 7.62 mm (.308 in) M60C machine guns were carried on the sponsons, accessed through large forward-opening hatches. The sponsons also had four racks to carry bombs, pods, or fuel. The wings outboard of the engines contained two additional hardpoints, one per side. Racked armament in the Vietnam War was usually seven-shot 2.75 in (70 mm) rocket pods with white phosphorus marker rounds or high-explosive rockets, or 5" (127 mm) four-shot Zuni rocket pods. Bombs, ADSIDS air-delivered/para-dropped unattended seismic sensors, Mk-6 battlefield illumination flares, and other stores were also carried.
Operational experience showed some weaknesses in the OV-10's design. It was significantly underpowered, which contributed to crashes in Vietnam in sloping terrain because the pilots could not climb fast enough. While specifications stated that the aircraft could reach 26,000 feet (7,900 m), in Vietnam the aircraft could reach only 18,000 feet (5,500 m). Also, no OV-10 pilot survived ditching the aircraft.
The OV-10 served in the U.S. Air Force, U.S. Marine Corps, and U.S. Navy, as well as in the service of a number of other countries. In U.S. military service, the Bronco was operated until the early Nineties, and obsoleted USAF OV-10s were passed on to the Bureau of Alcohol, Tobacco, and Firearms for anti-drug operations. A number of OV-10As furthermore ended up in the hands of the California Department of Forestry (CDF) and were used for spotting fires and directing fire bombers onto hot spots.
This was not the end of the OV-10 in American military service, though: In 2012, the type gained new attention because of its unique qualities. A $20 million budget was allocated to activate an experimental USAF unit of two airworthy OV-10Gs, acquired from NASA and the State Department. These machines were retrofitted with military equipment and were, starting in May 2015, deployed overseas to support Operation “Inherent Resolve”, flying more than 120 combat sorties over 82 days over Iraq and Syria. Their concrete missions remained unclear, and it is speculated they provided close air support for Special Forces missions, esp. in confined urban environments where the Broncos’ loitering time and high agility at low speed and altitude made them highly effective and less vulnerable than helicopters.
Furthermore, these Broncos reputedly performed strikes with the experimental AGR-20A “Advanced Precision Kill Weapons System (APKWS)”, a Hydra 70-millimeter rocket with a laser-seeking head as guidance - developed for precision strikes against small urban targets with little collateral damage. The experiment ended satisfactorily, but the machines were retired again, and the small unit was dissolved.
However, the machines had shown their worth in asymmetric warfare, and the U.S. Air Force decided to invest in reactivating the OV-10 on a regular basis, despite the overhead cost of operating an additional aircraft type in relatively small numbers – but development and production of a similar new type would have caused much higher costs, with an uncertain time until an operational aircraft would be ready for service. Re-activating a proven design and updating an existing airframe appeared more efficient.
The result became the MV-10H, suitably christened “Super Bronco” but also known as “Black Pony”, after the program's internal name. This aircraft was derived from the official OV-10X proposal by Boeing from 2009 for the USAF's Light Attack/Armed Reconnaissance requirement. Initially, Boeing proposed to re-start OV-10 manufacture, but this was deemed uneconomical, due to the expected small production number of new serial aircraft, so the “Black Pony” program became a modernization project. In consequence, all airframes for the "new" MV-10Hs were recovered OV-10s of various types from the "boneyard" at Davis-Monthan Air Force Base in Arizona.
While the revamped aircraft would maintain much of its 1960s-vintage rugged external design, modernizations included a completely new, armored central fuselage with a highly modified cockpit section, ejection seats and a computerized glass cockpit. The “Black Pony” OV-10 had full dual controls, so that either crewmen could steer the aircraft while the other operated sensors and/or weapons. This feature would also improve survivability in case of incapacitation of a crew member as the result from a hit.
The cockpit armor protected the crew and many vital systems from 23mm shells and shrapnel (e. g. from MANPADS). The crew still sat in tandem under a common, generously glazed canopy with flat, bulletproof panels for reduced sun reflections, with the pilot in the front seat and an observer/WSO behind. The Bronco’s original cargo capacity and the rear door were retained, even though the extra armor and defensive measures like chaff/flare dispensers as well as an additional fuel cell in the central fuselage limited the capacity. However, it was still possible to carry and deploy personnel, e. g. small special ops teams of up to four when the aircraft flew in clean configuration.
Additional updates for the MV-10H included structural reinforcements for a higher AUW and higher g load maneuvers, similar to OV-10D+ standards. The landing gear was also reinforced, and the aircraft kept its ability to operate from short, improvised airstrips. A fixed refueling probe was added to improve range and loiter time.
Intelligence sensors and smart weapon capabilities included a FLIR sensor and a laser range finder/target designator, both mounted in a small turret on the aircraft’s nose. The MV-10H was also outfitted with a data link and the ability to carry an integrated targeting pod such as the Northrop Grumman LITENING or the Lockheed Martin Sniper Advanced Targeting Pod (ATP). Also included was the Remotely Operated Video Enhanced Receiver (ROVER) to provide live sensor data and video recordings to personnel on the ground.
To improve overall performance and to better cope with the higher empty weight of the modified aircraft as well as with operations under hot-and-high conditions, the engines were beefed up. The new General Electric CT7-9D turboprop engines improved the Bronco's performance considerably: top speed increased by 100 mph (160 km/h), the climb rate was tripled (a weak point of early OV-10s despite the type’s good STOL capability) and both take-off as well as landing run were almost halved. The new engines called for longer nacelles, and their circular diameter markedly differed from the former Garrett T76-G-420/421 turboprop engines. To better exploit the additional power and reduce the aircraft’s audio signature, reversible contraprops, each with eight fiberglass blades, were fitted. These allowed a reduced number of revolutions per minute, resulting in less noise from the blades and their tips, while the engine responsiveness was greatly improved. The CT7-9Ds’ exhausts were fitted with muzzlers/air mixers to further reduce the aircraft's noise and heat signature.
Another novel and striking feature was the addition of so-called “tip sails” to the wings: each wingtip was elongated with a small, cigar-shaped fairing, each carrying three staggered, small “feather blade” winglets. Reputedly, this installation contributed ~10% to the higher climb rate and improved lift/drag ratio by ~6%, improving range and loiter time, too.
Drawing from the Iraq experience as well as from the USMC’s NOGS test program with a converted OV-10D as a night/all-weather gunship/reconnaissance platform, the MV-10H received a heavier gun armament: the original four light machine guns that were only good for strafing unarmored targets were deleted and their space in the sponsons replaced by avionics. Instead, the aircraft was outfitted with a lightweight M197 three-barrel 20mm gatling gun in a chin turret. This could be fixed in a forward position at high speed or when carrying forward-firing ordnance under the stub wings, or it could be deployed to cover a wide field of fire under the aircraft when it was flying slower, being either slaved to the FLIR or to a helmet sighting auto targeting system.
The original seven hardpoints were retained (1x ventral, 2x under each sponson, and another pair under the outer wings), but the total ordnance load was slightly increased and an additional pair of launch rails for AIM-9 Sidewinders or other light AAMs under the wing tips were added – not only as a defensive measure, but also with an anti-helicopter role in mind; four more Sidewinders could be carried on twin launchers under the outer wings against aerial targets. Other guided weapons cleared for the MV-10H were the light laser-guided AGR-20A and AGM-119 Hellfire missiles, the Advanced Precision Kill Weapon System upgrade to the light Hydra 70 rockets, the new Laser Guided Zuni Rocket which had been cleared for service in 2010, TV-/IR-/laser-guided AGM-65 Maverick AGMs and AGM-122 Sidearm anti-radar missiles, plus a wide range of gun and missile pods, iron and cluster bombs, as well as ECM and flare/chaff pods, which were not only carried defensively, but also in order to disrupt enemy ground communication.
In this configuration, a contract for the conversion of twelve mothballed American Broncos to the new MV-10H standard was signed with Boeing in 2016, and the first MV-10H was handed over to the USAF in early 2018, with further deliveries lasting into early 2020. All machines were allocated to the newly founded 919th Special Operations Support Squadron at Duke Field (Florida). This unit was part of the 919th Special Operations Wing, an Air Reserve Component (ARC) of the United States Air Force. It was assigned to the Tenth Air Force of Air Force Reserve Command and an associate unit of the 1st Special Operations Wing, Air Force Special Operations Command (AFSOC). If mobilized the wing was gained by AFSOC (Air Force Special Operations Command) to support Special Tactics, the U.S. Air Force's special operations ground force. Similar in ability and employment to Marine Special Operations Command (MARSOC), U.S. Army Special Forces and U.S. Navy SEALs, Air Force Special Tactics personnel were typically the first to enter combat and often found themselves deep behind enemy lines in demanding, austere conditions, usually with little or no support.
The MV-10Hs are expected to provide support for these ground units in the form of all-weather reconnaissance and observation, close air support and also forward air control duties for supporting ground units. Precision ground strikes and protection from enemy helicopters and low-flying aircraft were other, secondary missions for the modernized Broncos, which are expected to serve well into the 2040s. Exports or conversions of foreign OV-10s to the Black Pony standard are not planned, though.

The kit and its assembly:
This fictional Bronco update/conversion was simply spawned by the idea: could it be possible to replace the original cockpit section with one from an AH-1 Cobra, for a kind of gunship version?
The basis is the Academy OV-10D kit, mated with the cockpit section from a Fujimi AH-1S TOW Cobra (Revell re-boxing, though), chosen because of its “boxy” cockpit section with flat glass panels – I think that it conveys the idea of an armored cockpit section best. Combining these parts was not easy, though, even though the plan sound simple. Initially, the Bronco’s twin booms, wings and stabilizer were built separately, because this made PSR on these sections easier than trying the same on a completed airframe. One of the initial challenges: the different engines. I wanted something uprated, and a different look, and I had a pair of (excellent!) 1:144 resin engines from the Russian company Kompakt Zip for a Tu-95 bomber at hand, which come together with movable(!) eight-blade contraprops that were an almost perfect size match for the original three-blade props. Biggest problem: the Tu-95 nacelles have a perfectly circular diameter, while the OV-10’s booms are square and rectangular. Combining these parts and shapes was already a messy PST affair, but it worked out quite well – even though the result rather reminds of some Chinese upgrade measure (anyone know the Tu-4 copies with turboprops? This here looks similar!). But while not pretty, I think that the beafier look works well and adds to the idea of a “revived” aircraft. And you can hardly beat the menacing look of contraprops on anything...
The exotic, so-called “tip sails” on the wings, mounted on short booms, are a detail borrowed from the Shijiazhuang Y-5B-100, an updated Chinese variant/copy of the Antonov An-2 biplane transporter. The booms are simple pieces of sprue from the Bronco kit, the winglets were cut from 0.5mm styrene sheet.
For the cockpit donor, the AH-1’s front section was roughly built, including the engine section (which is a separate module, so that the basic kit can be sold with different engine sections), and then the helicopter hull was cut and trimmed down to match the original Bronco pod and to fit under the wing. This became more complicated than expected, because a) the AH-1 cockpit and the nose are considerably shorter than the OV-10s, b) the AH-1 fuselage is markedly taller than the Bronco’s and c) the engine section, which would end up in the area of the wing, features major recesses, making the surface very uneven – calling for massive PSR to even this out. PSR was also necessary to hide the openings for the Fujimi AH-1’s stub wings. Other issues: the front landing gear (and its well) had to be added, as well as the OV-10 wing stubs. Furthermore, the new cockpit pod’s rear section needed an aerodynamical end/fairing, but I found a leftover Academy OV-10 section from a build/kitbashing many moons ago. Perfect match!
All these challenges could be tackled, even though the AH-1 cockpit looks surprisingly stout and massive on the Bronco’s airframe - the result looks stockier than expected, but it works well for the "Gunship" theme. Lots of PSR went into the new central fuselage section, though, even before it was mated with the OV-10 wing and the rest of the model.
Once cockpit and wing were finally mated, the seams had to disappear under even more PSR and a spinal extension of the canopy had to be sculpted across the upper wing surface, which would meld with the pod’s tail in a (more or less) harmonious shape. Not an easy task, and the fairing was eventually sculpted with 2C putty, plus even more PSR… Looks quite homogenous, though.
After this massive body work, other hardware challenges appeared like small distractions. The landing gear was another major issue because the deeper AH-1 section lowered the ground clearance, also because of the chin turret. To counter this, I raised the OV-10’s main landing gear by ~2mm – not much, but it was enough to create a credible stance, together with the front landing gear transplant under the cockpit, which received an internal console to match the main landing gear’s length. Due to the chin turret and the shorter nose, the front wheel retracts backwards now. But this looks quite plausible, thanks to the additional space under the cockpit tub, which also made a belt feed for the gun’s ammunition supply believable.
To enhance the menacing look I gave the model a fixed refueling boom, made from 1mm steel wire and a receptor adapter sculpted with white glue. The latter stuff was also used add some antenna fairings around the hull. Some antennae, chaff dispensers and an IR decoy were taken from the Academy kit.
The ordnance came from various sources. The Sidewinders under the wing tips were taken from an Italeri F-16C/D kit, they look better than the missiles from the Academy Bronco kit. Their launch rails came from an Italeri Bae Hawk 200. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-10 and -19 missile pods on the stub wings were taken from the OV-10 kit.
Painting and markings:
Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 (suitably “Gunship Gray” :D) from above, FS 36375 underneath, with a low, wavy waterline, plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s.
The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).
The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth was taken from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.
Decals were also used to create the trim on the propeller blades and markings on the ordnance.
Finally, the model was sealed with a coat of matt acrylic varnish (Italeri) and some exhaust soot stains were added with graphite along the tail boom flanks.
A successful transplantation – but is this still a modified Bronco or already a kitbashing? The result looks quite plausible and menacing, even though the TOW Cobra front section appears relatively massive. But thanks to the bigger engines and extended wing tips the proportions still work. The large low-pressure tires look a bit goofy under the aircraft, but they are original. The grey livery works IMHO well, too – a more colorful or garish scheme would certainly have distracted from the modified technical basis.

They loved all my photos and some may make their newsletter!!! I added these to my set on the right, you can see how they jump, amazing dogs!!! I added all the winners at the bottom here!!
A charity event displaying the capabilities of police and corrections officer's K-9 partners. See the state's finest K-9 teams in competition, while helping to raise money for local charities.
The K-9 Olympics is entering its 19th year. The event is a day long competition involving K-9 units from local police departments, CT State Police, and Department of Corrections. Teams are evaluated during a ring competition in an arena style setting. Areas of competition include, but are not limited to, obedience, obstacles, evidence recovery, building search, marksmanship, and an apprehension drill. Also on display are the Connecticut State Police Emergency Services Unit, Trooper 1 Helicopter, Department of Corrections CERT team, narcotic and bomb detection dogs, and a variety of other police and animal related services. Money raised through the sales of shirts and food, and from donations, is returned to local charities. This year money raised will go to the "CHIPS" Program and Shriners Children's Burn Centers.
There are many different kinds of dogs used in police work. They may be trained in tactics or detection.
Patrol dogs protect their human police partners and may be trained to track and/or apprehend suspects. They may be trained to search buildings for suspects. They may work in corrections facilities.
Detector dogs may be trained to search for narcotics, bombs, lost people, accellerants, cadavers, or contraband.
The specific type of work the dog does determines how long training takes.
Training a police canine takes years. Most police departments import their dogs from Europe that have been trained in a sport such as Schutzhund, KNPV, or French Ring. They then modify the training that the dog has already received for street work. A police canine is trained in obedience, bite work, tracking, agility, handler protection, detection (Narcotics, or EOD). A lot goes into the training, most police canines are around - at least 2 years old before the canine is trained enough to hit the street.
For some drug sniffing dogs, you put the drug into a towel that has no scent of it's own, then let the dog sniff the towel, then you hide the towel, then tell the dog to find the towel which you have cleverly hidden with other towels that have other things wrapped up in it. Later you move to different towel, then in a long time, soak the towl in perfume and hide it. After a VERY long training period, your dog will be able to sniff out anything you train him or her to find.
Award winners at the 2010 Connecticut Police K-9 Olympics included:
First Place - Officer Rob Sabourin and Blade, from the state Department of Correction
Second Place - Officer Todd Mona and Primo, from East Hartford.
Third Place - Officer Andre Cox and Kazi, from the DOC.
“Most Experienced Team” - Officer Paul Osella and Benny, from the University of Connecticut.

1967 Triumph TR4A
An extremely successful sports car, the Triumph TR4 was produced in the U.K. by the Standard Triumph Motor Company from 1961. With a top speed of 110 mph, and costing around £1095, the TR4 became one of Triumph's best-loved cars thanks to its low cost of entry and capable open-top sports capabilities. The TR4 was stylistically quite a departure from its predecessor the TR3 and seemed to be just the car to bring the company into a brand new era.
Based on the chassis and drivetrain of TR predecessors, the TR4 was codenamed 'Zest' during development. Sporting a modern Giovanni Michelotti styled body, the new design was a big change from the classical cutaway door design of the earlier models, and allowed for full-sized doors with roll-up windows rather than side-curtains. The shapely tail end allowed for a spacious trunk, something that wasn't the norm for a sports car. A total of 40,253 TR4's were built during its production span.
This would be the first time that adjustable fascia ventilation was utilized in a production vehicle. Other advanced features included a 'backlight' option; a specialized hard top that consisted of a fixed glass rear window with an integral rollbar and a detachable, steel center panel. This would be the first time there ever was such a roof system on a production vehicle. The Porsche 911/912 Targa would be introduced in the next 5 years, and this type of roof would eventually become a well-known option.
Replaceable, the rigid roof came with an easily folded and stowed vinyl insert and supporting frame called a Surrey Top. There has been confusion in the past with the entire hard top assembly mistakenly referred to as a Surrey Top. The rigid top and backlight assembly is listed as the Hard Top kit in original factory parts catalogues and the vinyl insert and frame are offered separately as a Surrey Top. In an attempt to stay ahead of the competition Triumph introduced modern features like wind-down windows to appeal to the important US market. Some dealers were concerned that buyers wouldn't fully appreciate these modern amenities, so a short run of TR3As or TR3Bs were produced in 1961 and 1962.
Triumph used the pushrod 4-cylinder engine that was based on the early design of the Ferguson tractor engine, but increased the displacement from 1991 cc to 2138 cc by increasing the bore size. Other updates and modifications to the manifolds and cylinder head allowed for some improvements, which resulted in the TR4A model.
For the vehicles earmarked to compete in the under-two-liter classes of the time the 1991 cc engine became a no-cost option. Being that the engine was susceptible to crankshaft failure if revved beyond 6,500 rpm, select cars were fitted with vane-type superchargers. Superchargers allowed a TR4 to pump much more horsepower and torque at modest revolutions. Supercharged and otherwise performance-tuned, a 2.2-liter I4 version could produce more than 200 bhp, while a standard engine produced 105 bhp SAE. Like its predecessors, the TR4 was fitted with a wet-sleeve engine so the engine's cubic capacity could be changed by swapping the cylinder liners and pistons, for allowing a competitor to race under different capacity rules for competition use.
Other modifications from previous models included a wider track front and rear, a slightly larger standard engine displacement, rack and pinion steering and full synchromesh on all forward gears. The optional Laycock de Normanville electronically operated overdrive Laycock Overdrive could be picked for 2nd and 3rd gear, in addition to 4th, which effectively gave the TR4 a seven-speed manual close ratio gearbox. Initially the TR4 sported 15x4.5' disc wheels though optional 48-lace wire wheels could be ordered painted the same shade as the vehicles bodywork, in a matte or polished chrome finishes, or stove-enameled (matte silver with chrome spinners). The 155x15 bias ply was the most typical tire for the TR4. American Racing alloy; magnesium and aluminum wheels were offered in the U.S. at one time in 15x5.5' ox 15x6' sizes. The correct size radial-ply tire for the factory rims was 155x15, and only available from Michelin for an extravagant amount, was a problem when original owned opted for 60-spoke wire wheels. The standard 185x15 radials were much too wide to be fitted safely and as such, many owners had new and wider rims fitted and their wheels re-laced.
The TR4A with IRS or independent rear suspension was the successor the TR4 in 1965. There wasn't much difference between the two models except for the rear suspension, which used trailing arms and a differential bolted to the redesigned chassis frame and a few minor updates. It is estimated that around 25% of TR4As not equipped with IRS were instead reverted to a live axle design like the TR4, which was adapted to fit the new chassis.

I'm experimenting with the scanning capabilities of my multi-function printer... mostly because I'm avoiding working on my database final.
This is an oldold picture of my grandparent's kitchen in Jasło, Poland, sometime during the summer of 1993. My grandmother (on my mom's side) died when I was 17, and this was the last time I saw her before she passed away. She had cancer of nearly ever internal organ, largely due to fall-out from the Chernobyl blast. This was also taken not long after the fall of Communism in Poland, and it was the first time I remember seeing food and merchandise in the stores. Shelves were full! People weren't afraid of us as we walked down the street. It was a time ripe with hope for a new age.
This is the second Baz Luhrmann film that I'm quoting in this series.
Continuing on with my affinity for twisted love stories....Luhrman's 1996 film Romeo+Juliet is a modern interpretation of the classic Shakespeare, anachronistically juxtaposing Shakespeare's original language against a modern landscape of consumption and capitalism.
As with all of Luhrman's films, the visual style is rich and detailed, vibrantly coloured and surreal. He paints a rather sickening view of modern society, with petty vanities slathered upon the grotesque criminals of upper class society. In the midst of such ugliness, Romeo and Juliet emerge, as yet untouched by the poisonous world around them.
I've read criticism that claims Romeo and Juliet must die in order to keep their love untainted. This film takes that purity one step further: In the end Romeo and Juliet have no choice but to die, or to succumb to the grotesqueries that their parents have grown into.
This film accomplishes the ideal that I believe all film adaptations of stage plays should strive toward: it brings the work of theatre to life in a manner unique to film, using the capabilities of the medium to inform a new, deeper understanding of the original work. The play is incredibly powerful on its own. Luhrmann has built upon Shakespeare's original work to create something contemporary, relevant, beautiful and impassioned. I am in awe of his work.
Big thanks to Happy_Peasant for sending me a bird image just so I could have my wings!

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
Clarence L. "Kelly" Johnson, vice president of engineering and research at Lockheed's Skunk Works, visited USAF air bases across South Korea in November 1951 to speak with fighter pilots about what they wanted and needed in a fighter aircraft. At the time, the American pilots were confronting the MiG-15 with North American F-86 Sabres, and many felt that the MiGs were superior to the larger and more complex American design. The pilots requested a small and simple aircraft with excellent performance, especially high speed and altitude capabilities. Armed with this information, Johnson immediately started the design of such an aircraft on his return to the United States.
Work started in March 1952. In order to achieve the desired performance, Lockheed chose a small and simple aircraft, weighing in at 12,000 lb (5,400 kg) with a single powerful engine. The engine chosen was the new General Electric J79 turbojet, an engine of dramatically improved performance in comparison with contemporary designs. The small L-246 design remained essentially identical to the Model 083 Starfighter as eventually delivered.
Johnson presented the design to the Air Force on 5 November 1952, and work progressed quickly, with a mock-up ready for inspection at the end of April, and work starting on two prototypes that summer. The first prototype was completed by early 1954 and first flew on 4 March at Edwards AFB. The total time from contract to first flight was less than one year.
The first YF-104A flew on 17 February 1956 and, with the other 16 trial aircraft, were soon carrying out equipment evaluation and flight tests. Lockheed made several improvements to the aircraft throughout the testing period, including strengthening the airframe, adding a ventral fin to improve directional stability at supersonic speed, and installing a boundary layer control system (BLCS) to reduce landing speed. Problems were encountered with the J79 afterburner; further delays were caused by the need to add AIM-9 Sidewinder air-to-air missiles. On 28 January 1958, the first production F-104A to enter service was delivered.
Even though the F-104 saw only limited use by the USAF, later versions, tailored to a fighter bomber role and intended for overseas sales, were more prolific. This was in particular the F-104G, which became the Starfighter's main version, a total of 1,127 F-104Gs were produced under license by Canadair and a consortium of European companies that included Messerschmitt/MBB, Fiat, Fokker, and SABCA.
The F-104G differed considerably from earlier versions. It featured strengthened fuselage, wing, and empennage structures; a larger vertical fin with fully powered rudder as used on the earlier two-seat versions; fully powered brakes, new anti-skid system, and larger tires; revised flaps for improved combat maneuvering; a larger braking chute. Upgraded avionics included an Autonetics NASARR F15A-41B multi-mode radar with air-to-air, ground-mapping, contour-mapping, and terrain-avoidance modes, as well as the Litton LN-3 Inertial Navigation System, the first on a production fighter.
Germany was among the first foreign operators of the F-104G variant. As a side note, a widespread misconception was and still is that the "G" explicitly stood for "Germany". But that was not the case and pure incidence, it was just the next free letter, even though Germany had a major influence on the aircraft's concept and equipment. The German Air Force and Navy used a large number of F-104G aircraft for interception, reconnaissance and fighter bomber roles. In total, Germany operated 916 Starfighters, becoming the type's biggest operator in the world. Beyond the single seat fighter bombers, Germany also bought and initially 30 F-104F two-seat aircraft and then 137 TF-104G trainers. Most went to the Luftwaffe and a total of 151 Starfighters was allocated to the Marineflieger units.
The introduction of this highly technical aircraft type to a newly reformed German air force was fraught with problems. Many were of technical nature, but there were other sources of problems, too. For instance, after WWII, many pilots and ground crews had settled into civilian jobs and had not kept pace with military and technological developments. Newly recruited/re-activated pilots were just being sent on short "refresher" courses in slow and benign-handling first-generation jet aircraft or trained on piston-driven types. Ground crews were similarly employed with minimal training and experience, which was one consequence of a conscripted military with high turnover of service personnel. Operating in poor northwest European weather conditions (vastly unlike the fair-weather training conditions at Luke AFB in Arizona) and flying low at high speed over hilly terrain, a great many Starfighter accidents were attributed to controlled flight into terrain (CFIT). German Air Force and Navy losses with the type totaled 110 pilots, around half of them naval officers.
One general contributing factor to the high attrition rate was the operational assignment of the F-104 in German service: it was mainly used as a (nuclear strike) fighter-bomber, flying at low altitude underneath enemy radar and using landscape clutter as passive radar defense, as opposed to the original design of a high-speed, high-altitude fighter/interceptor. In addition to the different and demanding mission profiles, the installation of additional avionic equipment in the F-104G version, such as the inertial navigation system, added distraction to the pilot and additional weight that further hampered the flying abilities of the plane. In contemporary German magazine articles highlighting the Starfighter safety problems, the aircraft was portrayed as "overburdened" with technology, which was considered a latent overstrain on the aircrews. Furthermore, many losses in naval service were attributed to the Starfighter’s lack of safety margin through a twin-engine design like the contemporary Blackburn Buccaneer, which had been the German navy air arm’s favored type. But due to political reasons (primarily the outlook to produce the Starfighter in Southern Germany in license), the Marine had to accept and make do with the Starfighter, even if it was totally unsuited for the air arm's mission profile.
Erich Hartmann, the world's top-scoring fighter ace from WWII, commanded one of Germany's first (post-war) jet fighter-equipped squadrons and deemed the F-104 to be an unsafe aircraft with poor handling characteristics for aerial combat. To the dismay of his superiors, Hartmann judged the fighter unfit for Luftwaffe use even before its introduction.
In 1966 Johannes Steinhoff took over command of the Luftwaffe and grounded the entire Luftwaffe and Bundesmarine F-104 fleet until he was satisfied that the persistent problems had been resolved or at least reduced to an acceptable level. One measure to improve the situation was that some Starfighters were modified to carry a flight data recorder or "black box" which could give an indication of the probable cause of an accident. In later years, the German Starfighters’ safety record improved, although a new problem of structural failure of the wings emerged: original fatigue calculations had not taken into account the high number of g-force loading cycles that the German F-104 fleet was experiencing through their mission profiles, and many airframes were returned to the depot for wing replacement or outright retirement.
The German F-104Gs served primarily in the strike role as part of the Western nuclear deterrent strategy, some of these dedicated nuclear strike Starfighters even had their M61 gun replaced by an additional fuel tank for deeper penetration missions. However, some units close to the German borders, e.g. Jagdgeschwader (JG) 71 in Wittmundhafen (East Frisia) as well as JG 74 in Neuburg (Bavaria), operated the Starfighter as a true interceptor on QRA duty. From 1980 onwards, these dedicated F-104Gs received a new air superiority camouflage, consisting of three shades of grey in an integral wraparound scheme, together with smaller, subdued national markings. This livery was officially called “Norm 82” and unofficially “Alberich”, after the secretive guardian of the Nibelung's treasure. A similar wraparound paint scheme, tailored to low-level operations and consisting of two greens and black (called Norm 83), was soon applied to the fighter bombers and the RF-104 fleet, too, as well as to the Luftwaffe’s young Tornado IDS fleet.
However, the Luftwaffe’s F-104Gs were at that time already about to be gradually replaced, esp. in the interceptor role, by the more capable and reliable F-4F Phantom II, a process that lasted well into the mid-Eighties due to a lagging modernization program for the Phantoms. The Luftwaffe’s fighter bombers and recce Starfighters were replaced by the MRCA Tornado and RF-4E Phantoms. In naval service the Starfighters soldiered on for a little longer until they were also replaced by the MRCA Tornado – eventually, the Marineflieger units received a two engine aircraft type that was suitable for their kind of missions.
In the course of the ongoing withdrawal, a lot of German aircraft with sufficiently enough flying hours left were transferred to other NATO partners like Norway, Greece, Turkey and Italy, and two were sold to the NASA. One specific Starfighter was furthermore modified into a CCV (Control-Configured Vehicle) experimental aircraft under control of the German Industry, paving the way to aerodynamically unstable aircraft like the Eurofighter/Typhoon. The last operational German F-104 made its farewell flight on 22. Mai 1991, and the type’s final flight worldwide was in Italy in October 2004.

The kit and its assembly:
A relatively simple what-if project – based on the question how a German F-104 interceptor might have looked like, had it been operated for a longer time to see the Luftwaffe’s low-viz era from 1981 onwards. In service, the Luftwaffe F-104Gs started in NMF and then carried the Norm 64 scheme, the well-known splinter scheme in grey and olive drab. Towards the end of their career the fighter bombers and recce planes received the Norm 83 wraparound scheme in green and black, but by that time no dedicated interceptors were operational anymore, so I stretched the background story a little.
The model is the very nice Italeri F-104G/S model, which is based on the ESCI molds from the Eighties, but it comes with recessed engravings and an extra sprue that contains additional drop tanks and an Orpheus camera pod. The kit also includes a pair of Sidewinders with launch rails for the wing tips as well as the ventral “catamaran” twin rail, which was frequently used by German Starfighters because the wing tips were almost constantly occupied with tanks.
Fit and detail is good – the kit is IMHO very good value for the money. There are just some light sinkholes on the fuselage behind the locator pins, the fit of the separate tail section is mediocre and calls for PSR, and the thin and very clear canopy is just a single piece – for open display, you have to cut it by yourself.
Since the model would become a standard Luftwaffe F-104G, just with a fictional livery, the kit was built OOB. The only change I made are drooped flaps, and the air brakes were mounted in open position.
The ordnance (wing tip tanks plus the ventral missiles) was taken from the kit, reflecting the typical German interceptor configuration: the wing tips were frequently occupied with tanks, sometimes even together with another pair of drop tanks under the wings, so that any missile had to go under the fuselage. The instructions for the ventral catamaran launch rails are BTW wrong – they tell the builder to mount the launch rails onto the twin carrier upside down! Correctly, the carrier’s curvature should lie flush on the fuselage, with no distance at all. When mounted as proposed, the Sidewinders come very close to the ground and the whole installation looks pretty goofy! I slightly modified the catamaran launch rail with some thin styrene profile strips as spacers, and the missiles themselves, AIM-9Bs, were replaced with more modern and delicate AIM-9Js from a Hasegawa air-to-air weapons set. Around the hull, some small blade antennae, a dorsal rotating warning light and an angle-of-attack sensor were added.
Painting and markings:
The exotic livery is what defined this what-if build, and the paint scheme was actually inspired by a real world benchmark: some Dornier Do-28D Skyservants of the German Marineflieger received, late in their career, a wraparound scheme in three shades of grey, namely RAL 7030 (Steingrau), 7000 (Fehgrau) and 7012 (Basaltgrau). I thought that this would work pretty well for an F-104G interceptor that operates at medium to high altitudes, certainly better than the relatively dark Norm 64 splinter scheme or the Norm 83 low-altitude pattern.
The camouflage pattern was simply adopted from the Starfighter’s Norm 83 scheme, just the colors were exchanged. The kit was painted with acrylic paints from Revell, since the authentic tones were readily available, namely 75, 57 and 77. As a disrupting detail I gave the wing tip tanks the old Norm 64 colors: uniform Gelboliv from above (RAL 6014, Revell 42), Silbergrau underneath (RAL 7001, Humbrol’s 127 comes pretty close), and bright RAL 2005 dayglo orange markings, the latter created with TL Modellbau decal sheet material for clean edges and an even finish.
The cockpit interior was painted in standard medium grey (Humbrol 140, Dark Gull Grey), the landing gear including the wells became aluminum (Humbrol 56), the interior of the air intakes was painted with bright matt aluminum metallizer (Humbrol 27001) with black anti-icing devices in the edges and the shock cones. The radome was painted with very light grey (Humbrol 196, RAL 7035), the dark green anti-glare panel is a decal from the OOB sheet.
The model received a standard black ink washing and some panel post-shading (with Testors 2133 Russian Fulcrum Grey, Humbrol 128 FS 36320 and Humbrol 156 FS 36173) in an attempt to even out the very different shades of grey. The result does not look bad, pretty worn and weathered (like many German Starfighters), even though the paint scheme reminds a lot of the Hellenic "Ghost" scheme from the late F-4Es and the current F-16s?
The decals for the subdued Luftwaffe markings were puzzled together from various sources. The stencils were mostly taken from the kit’s exhaustive and sharply printed sheet. Tactical codes (“26+40” is in the real Starfighter range, but this specific code was AFAIK never allocated), iron crosses and the small JG 71 emblems come from TL Modellbau aftermarket sheets. Finally, after some light soot stains around the gun port, the afterburner and some air outlets along the fuselage with graphite, the model was sealed with matt acrylic varnish.
A simple affair, since the (nice) kit was built OOB and the only really fictional aspect of this model is its livery. But the resulting aircraft looks good, the all-grey wraparound scheme suits the slender F-104 well and makes an interceptor role quite believable. Would probably also look good on a German Eurofighter? Certainly more interesting than the real world all-blue-grey scheme.
In the beauty pics the scheme also appears to be quite effective over open water, too, so that the application to the Marineflieger Do-28Ds made sense. However, for the real-world Starfighter, this idea came a couple of years too late.
Initially, I mistook this for a first-generation Ford Bronco, which has similar square-cut lines. International Harvester produced the Scout between 1961 and 1980, a pioneering 4WD vehicle with recreational off-road capabilities, these days popularised by the ubiquitous SUV.

Some background:
The Austrian Air Force in its current form was created in May 1955 by the victorious Allied powers, subject to restrictions on its use of guided missiles. The Austrian State Treaty of 1955 committed Austria to permanent neutrality. Pilot training started out with a four Yak-11 Moose and four Yak-18 Max aircraft donated by the Soviet Union, and Austria purchased further light trainer types under the Military Assistance Program. Until 1960 Austria purchased training and support aircraft under the MAP, but no modern fighter aircraft; the role of a fighter was rather inadequately filled by thirty already outdated Saab 29 Tunnan, bought second-hand from the Swedish Air Force in the early 1960s which equipped two fighter bomber squadrons.
To expand its capabilities and modernize the fleet, Austria purchased from 1970 on a total of 40 Saab 105 lightweight multi-role aircraft from Sweden with the intention to deploy them in trainer, reconnaissance, ground attack and even interception roles. As it became clear in the 1980s that the light sub-sonic aircraft were inadequate for air combat and airspace interdiction, Austria started looking for a more capable aircraft. In 1984, Austria had devised a two-phase solution to its problem: buying 30 interim aircrafts cheaply as a stopgap and then trading them back for a new generation aircraft in the early or mid-Nineties.
International response was quick and manifold: Bristol Aerospace offered initially ex RAF Jaguars to be replaced by Tornado F.3 or even Eurofighters; Saab-Scania offered between 24 and 30 former Royal Swedish Air Force J 35D Draken, followed by Saab J 39 Gripen as future substitutes; General-Electric suggested downgraded F-16/79 or F-16A for phase one and an option for the same aircraft in a more modern variant for phase two; Northrop’s numberF-5E was another alternative for phase one. Dassault was also present with refurbished Mirage III initially, followed by Mirage 2000.
Finding the most suitable option in this mass was not easy, and eventually a surprising deal materialized: In 1985 the contract for the sale of twenty-four Lightning F.56 fighters plus four T.55 trainers was signed by the SPÖ/FPÖ government under Fred Sinowatz. The background: Saudi Arabia had been operating thirty-four F.53 single-seaters and six T.55 trainers since 1967 and was about to retire its fleet, which was still in very good condition and with a reasonable number of flying hours left on many airframes. The aircraft would be refurbished directly at BAe in Great Britain with the option to switch to the Tornado ADV or its successor, the Eurofighter Typhoon, later.
The Lightning F.53 was an export version of the RAF’s F.6, but with a multi-role mission profile in mind that included, beyond the primary interceptor mission with guided missiles or internal guns, the capability to carry out interdiction/ground attacks and reconnaissance missions. To carry a suitable ordnance load, the F.53 featured additional underwing pylons for bombs or unguided rocket pods. Instead of the standard Firestreak/Red Top AAM missile station in the lower front fuselage, two retractable panniers with a total of forty-four unguided 50 mm rockets, which were effective against both ground and aerial targets, could be installed, or, alternatively, two camera packs (one with five cameras and another with a rotating camera mount) was available for tactical photo reconnaissance missions. Overwing hardpoints, adapted from the Lightning F.6, allowed to carry auxiliary fuel tanks to increase range/endurance, additional rocket pods or even retarded bombs.
The Lightning T.55 was also an export variant, a two-seat side-by-side training aircraft, and virtually identical to the T.5, which itself was based on the older F.3 fighter variant, and fully combat-capable.
The Saudi Arabian multi-role F.53s had served in the ground-attack and reconnaissance roles as well as an air defense fighter, with Lightnings of No. 6 Squadron RSAF carrying out ground-attack missions using rockets and bombs during a border dispute with South Yemen between December 1969 and May 1970. Saudi Arabia received Northrop F-5E fighters from 1971, which resulted in the Lightnings relinquishing the ground-attack mission, concentrating on air defense, and to a lesser extent, reconnaissance. Until 1982, Saudi Arabia's Lightnings were mainly operated by 2 and 6 Squadron RSAF (although a few were also used by 13 Squadron RSAF), but when 6 Squadron re-equipped with the F-15 Eagle from 1978 on, all the remaining aircraft were concentrated and operated by 2 Squadron at Tabuk. In 1985, as part of the agreement to sell the Panavia Tornado (both IDS and ADV versions) to the RSAF, the Lightnings were traded in to British Aerospace, returned to Warton for refurbishment and re-sold to Austria.
While the Saudi Arabian Lightnings’ hardware was in very good shape, the Austrian Bundesluftwaffe requested some modifications, including a different missile armament: instead of the maintenance-heavy British Firestreak/Red Top AAMs, the Lightnings were to be armed with simpler, lighter and more economical IR-guided AIM-9 Sidewinder AAMs which were already in the Austrian Air Force’s inventory. Two of these missiles were carried on single launch rails on the lower forward fuselage; an additional pair of Sidewinders could also be carried on the outer underwing stations, for a total of four. The F.53s’ optional retractable unguided rocket panniers were dropped altogether in favor of a permanent avionics bay for the Sidewinders in its place. However, to carry out tactical reconnaissance tasks (formerly executed by J 29Fs with a removable camera pod instead of the portside gun bay), four Austrian Lightnings frequently had one of the optional camera compartments installed, thereby losing the capability to deploy Sidewinders, though.
Among other things, the machines were furthermore upgraded with new bird strike-proof cockpit glazing, avionics were modernized, and several other minor customer requests were adopted, like a 0.6-megacandela night identification light. This spotlight is mounted in the former portside gun bay in front of the cockpit, and an anti-glare panel was added under the windscreen.
The fixed in-flight refueling probe was deleted, as this was not deemed necessary anymore since the Lightnings would exclusively operate within neutral Austria’s borders. The probes could, however, be re-installed, even though the Austrian pilots would not receive on-flight refueling training. The Lightnings' optional 260 imp gal overwing tanks were retained since they were considered to be sufficient for extended subsonic air patrols or eventual ferry flights.
The refurbished Lightnings were re-designated F.56 and delivered in batches of four between 1987 and 1989 to the Austrian Air Force’s 1st and then 2nd Fighter Squadrons, carrying a grey air superiority paint scheme. At that time, the airframes had between 1,550 and 2,800 flight hours and all had a general overhaul behind them. In 1991, the Lightings were joined by eighteen German ex-NVA-LSK MiG-23s, which were transferred to Austrian Air Force's ‘Fliegerwerft B’ at Nittner Air Base, where they'd be overhauled and updated with NATO-compatible equipment. As MiG-23Ö they were exclusively used as interceptors, too.
Shortly after their introduction, the Austrian Lightnings saw their first major use in airspace interdiction starting 1991 during the Yugoslav Wars, when Yugoslav MiG-21 fighters frequently crossed the Austrian border without permission. In one incident on 28 June a MiG-21 penetrated as far as Graz, causing widespread demands for action. Following repeated border crossings by armed aircraft of the Yugoslav People's Army, changes were suggested to the standing orders for aircraft armament.
With more and more practice and frequent interceptions one of the Lightning's basic flaws became apparent: its low range. Even though the Lightning had a phenomenal acceleration and rate of climb, this was only achieved in a relatively clean configuration - intercepting intruders was one thing but escorting them back to the Austrian border or an assigned airfield, as well as standing air patrols, were a different thing. With more tactical experience, the overwing tanks were taken back into service, even though they were so draggy that their range benefit was ultimately zero when the aircraft would use its afterburners during a typical interception mission. Therefore, the Austrian QRA Lightnings were typically operated in pairs: one clean and only lightly armed (typically with the guns and a pair of AIM-9s), to make a quick approach for visual intruder identification and contact, while a second aircraft with extra fuel would follow at high subsonic speed and eventually take over and escort the intruder. Airspace patrol was primarily executed with the MiG-23Ö, because it had a much better endurance, thanks to its VG wings, even though the Floggers had a poor service record, and their maintenance became ever more complicated.
After more experience, the Austrian Lightnings received in 1992 new ALR-45 radar detectors in a fairing on the fin top as well as chaff and flare dispenser systems, and the communication systems were upgraded, too. In 2004 the installation of Garmin 295 moving map navigation devices followed, even though this turned out to be a negligible update: on December 22, 2005, the active service life and thus military use of the Lightnings in general ended, and Austria was the last country to decommission the type, more than 50 years after the first flight of the prototype on August 4, 1954.
The Austrian Lightnings’ planned service period of 10 years was almost doubled, though, due to massive delays with the Eurofighter’s development: In 2002, Austria had already selected the Typhoon as its new “Phase II” air defense aircraft, having beaten the F-16 and the Saab Gripen in competition, and its introduction had been expected to occur from early 2005 on, so that the Lightnings could be gradually phased out. The purchase of 18 Typhoons was agreed on 1 July 2003, but it would take until 12 July 2007 that the first Typhoon would eventually be delivered to Zeltweg Air Base and formally enter service with the Austrian Air Force. This operational gap had to be bridged with twelve F-5E leased from Switzerland for EUR 75 mio., so that Quick Reaction Alert (QRA) duties for the Austrian airspace could be continued.

The kit and its assembly:
This was another submission to the “Hunter, Lightning and Canberra” group build at whatifmodellers.com in 2022 and intended as a rather simple build since it was based on an alternate reality plot: the weird story that Austria was offered a revamped fleet of ex-Saudi Arabian Lightnings is true(!), but the decision eventually fell in favor of revamped Saab J 35Ds from Sweden. For this what-if build I used the real historic timeline, replaced the aircraft, and built both story and model around this – and the result became the BAC Lightning F.56 in Austrian Air Force service.
Initially I wanted to use an Airfix BAC Lightning in The Stash™, a really nice model kit and a relatively new mold, but it turned out to be the kit’s F.2A variant. While very similar to the F.6, changing it into a F.53 analogue with the OOB parts turned out to be too complex for my taste. For instance, the F.2A kit lacks the ventral gun bay (it just comes with the auxiliary tank option since the guns are already located in front of the cockpit) and the cable conduits on the lower flanks. Procuring a suitable and priceworthy Airfix F.6 turned out to be impossible, but then I remembered a Hasegawa Lightning F.6 in The Stash™ that I had shot at ev!lbay many moons ago for a laughable price and without a concrete plan. However, this kit is pretty old: it has raised (yet quite fine, less robust than the Matchbox kit) panel lines and even comes with a pilot figure, but also many weak spots like the air intake and the jet exhausts that end in flat walls after some millimeters depth and a very basic cockpit. But for this rather simple what-if project the kit appeared to be a suitable basis, and it would eventually find a good use.
The Hasegawa Lightning was basically built OOB, even though I made some cosmetic amendments like a better seat for the pilot, hydraulic fluid lines on the landing gear made from wire or opening the flat walls inside of the air intake opening and the jet nozzles. Behind the radome, a simple splitter plate was added as well as a recessed bulkhead in front of an implanted Me 262 cockpit tub (the Hasegawa kit just offers a bare floor panel, nothing else!), the afterburners were extended inwards with parts from a Matchbox A.W. Meteor night fighter.
The Red Top AAMs and the in-flight refueling probe were omitted. Instead, I added extra F.53-style forward-swept pylons under the outer wings, scratched from 1.5 mm styrene sheet due to their odd, raked shape, and I added Sidewinder launch rails plus suitable missiles from a Hasegawa air-to-air weapons set to all four stations. After long consideration I also retained the ‘overburger’ tanks, partly because of the unique layout on the Lightning, and also because of operational considerations.
Chaff dispensers were scratched from styrene profiles and placed at the fin’s base. A fairing for the retrofitted radar warning sensor was added to the fin tip, created from 1.5 mm styrene sheet.
Painting and markings:
To reflect the “alternate reality” role of the Lightning I gave the model a livery similar to the Saab J 35Ö that were actually procured: an adaptation of the USAF “Egypt One” scheme, carried primarily by the USAF F-16s. Adapting this simple three-tone camouflage from the flat F-16 to the Draken was easy and straightforward, but applying it to a Lightning with its many vertical surfaces turned out to be a tough challenge. I eventually came up with a paint scheme that reminds of the late RAF low-viz Lightning liveries, which existed in a wide range of patterns and graduations of grey.
The colors were authentic, FS 36118, 36270 and 36375 (using Humbrol 125, 126 and 127), and I decided to emphasize the camouflage of the flanks against the horizon, so that the vertical surfaces and the fin became FS 36270. The undersides of wings, stabilizers and fuselage became FS 36375. The dark FS 36118 was only applied to the upper sides of the wings and the stabilizer, and to a high dorsal section, starting at the wing roots. As a small contrast, the tank area on the spine was painted in light grey, simulating unpainted fiber glass. The radome was painted with a streaky mix of Humbrol 155 and 56.
As usual, the model received a light black ink washing, some post-panel-shading in lighter tones, and, due to the raised panel lines, was very lightly rubbed with graphite. The cockpit interior was painted in medium grey (Revell 47) with an olive drab fabric fairing behind the black pilot seat, which received ejection handles made from thin wire as eye candy. The landing gear and the respective wells were painted in Humbrol 56 (Aluminum Dope).
The decals are a wild mix: The fuselage roundels are actually wing markings from a Hasegawa J 35OE, as well as the huge orange "06" on the wings (I could not resist; they will later be partly obscured by the overwing tanks, but the heck with it!). The roundels on the wings come from a generic TL Modellbau sheet - I found that I needed larger markings than those on the Draken.
Both unit and individual aircraft identifiers are single black DIN font digits, also from TL Modellbau. The unit badges on the fin are authentic, even though from an earlier era: they came from an Austrian J 29 of Fliegerregiment 2 from a PrintScale sheet, and all stencils were taken from the OOB low-viz RAF markings sheet, plus four small warning triangles for the underwing pylons.
A ‘what-if’ model in the purest sense, since this model depicts what could really have been: ex Saudi-Arabian export BAC Lightnings over the Austrian Alps! However, refurbished Saab J 35D Draken made the race (and later followed by the Eurofighter Typhoon at ‘Stage 2’), so that this Lightning remains fictional. It does not look bad in the ‘Egypt One’ paint scheme, though, better than expected!

Grand Canyon is a large multipurpose offshore construction vessel (OSV) capable of performing a variety of subsea activities such as jet trenching and heavy soil trenching. The high manoeuvrability and station keeping capabilities of the vessel allow it to operate even in adverse climatic conditions.
Norwegian ship-builder Bergen Group received the order for construction of the Grand Canyon from Volstad Maritime in December 2010. The keel of the vessel was laid in August 2011. The construction was carried out at Fosen in Rissa, Sør-Trøndelag.
The hull of the vessel was manufactured by Tersan Shipyard in Turkey.
The hull was launched in January 2012 in the presence of the Norwegian Prime Minister, Jens Stoltenberg. It was then towed to Bergen Group's shipyard in Norway for final outfitting.
Grand Canyon was delivered in November 2012 having completed sea trials in October. The new build was financed by three Norwegian finance groups - Garanti-instituttet for eksportkreditt (GIEK), Export Credit Norway (Eksportkreditt) and SpareBank 1 SMN.
The vessel is currently on a five-year charter with Canyon Offshore, a company owned by Helix Energy Solutions Group.
Features of Volstad's new offshore construction vessel
Grand Canyon is built according to the ST 259 CD design developed by the Norwegian ship designer Skipsteknisk. The vessel carries DNV's 'Clean Design' notation for its eco-friendly operation.
The vessel boasts a dynamic positioning (DP) Class-3 control system for automatic positioning and heading. She can be deployed for use in shallower depths because of her modest draught.
In order to carry out subsea installation, burial support operations and general offshore construction work, the vessel is provided with a working platform that is stable and has a large capacity. Jet trenching can be performed from the ship's forward port side, while soil trenching can be carried out from the aft of the vessel.
The vessel features two indoor remotely operated vehicle (ROV) hangars, which can be prepared for the deployment of up to five work-class ROVs (WROV). The ROVs can be deployed to a depth of 3,000m.
A carousel reel-drive system is installed below the ship's deck which is able to lay power cables, pipelines and umbilicals into the trench at the seabed. Once placed, these cables or pipelines can be buried below the surface of the sea to a depth of up to 9m with the help of the ROVs.
The under-deck has enough strength to bear the load of heavy equipment, which allows the crew to finish mobilisation and demobilisation operations in shorter times.
Main dimensions and accommodation
The dead weight of the vessel is 7,000t, while gross and net tonnages are 12,652t and 3,796t respectively. She has an overall length of 127.75m, a moulded breadth of 25m and scantling draught of 7.5m. The length between perpendiculars is 114.6m, and the deck area is 1,650m².
The Grand Canyon accommodates up to 104 people in single and double cabins. Facilities onboard the vessel include a meeting room, internet café, reception, sauna, gym, coffee house and hospital.
The vessel is equipped with two cranes, including an active heave compensated (AHC) offshore crane, the MacGregor HMC 4240. The crane has a safe working load of 250t at 10m outreach capacity. The second crane is the MacGregor HMC 2201 model and can lift 15t at 20m outreach.
Grand Canyon is powered by a diesel-electric propulsion system. The ship is fitted with six six-cylinder Wärtsilä 32 main engines. Each engine generates 2,880kW of power at 720rpm and drives a NES generator (NEGR 710 LB10 model) rated at 3,450kVA. In addition, there is a nine-cylinder Wärtsilä 20 emergency generator of 1,665kW capacity and a Mitsubishi S6R-MTPA harbour generator of 595kW capacity.
Propulsion is provided by two electric motors of 2,500kW each. Side thrusters comprise six Wärtsilä tunnel thrusters, each with 2,000kW of power. Four of the thrusters are mounted forward and the other two are mounted aft.

The Saudi Arabian multi-role F.53s had served in the ground-attack and reconnaissance roles as well as an air defense fighter, with Lightnings of No. 6 Squadron RSAF carrying out ground-attack missions using rockets and bombs during a border dispute with South Yemen between December 1969 and May 1970. Saudi Arabia received Northrop F-5E fighters from 1971, which resulted in the Lightnings relinquishing the ground-attack mission, concentrating on air defense, and to a lesser extent, reconnaissance. Until 1982, Saudi Arabia's Lightnings were mainly operated by 2 and 6 Squadron RSAF (although a few were also used by 13 Squadron RSAF), but when 6 Squadron re-equipped with the F-15 Eagle from 1978 on, all the remaining aircraft were concentrated and operated by 2 Squadron at Tabuk. In 1985, as part of the agreement to sell the Panavia Tornado (both IDS and ADV versions) to the RSAF, the Lightnings were traded in to British Aerospace, returned to Warton for refurbishment and re-sold to Austria.
While the Saudi Arabian Lightnings’ hardware was in very good shape, the Austrian Bundesluftwaffe requested some modifications, including a different missile armament: instead of the maintenance-heavy British Firestreak/Red Top AAMs, the Lightnings were to be armed with simpler, lighter and more economical IR-guided AIM-9 Sidewinder AAMs which were already in the Austrian Air Force’s inventory. Two of these missiles were carried on single launch rails on the lower forward fuselage; an additional pair of Sidewinders could also be carried on the outer underwing stations, for a total of four. The F.53s’ optional retractable unguided rocket panniers were dropped altogether in favor of a permanent avionics bay for the Sidewinders in its place. However, to carry out tactical reconnaissance tasks (formerly executed by J 29Fs with a removable camera pod instead of the portside gun bay), four Austrian Lightnings frequently had one of the optional camera compartments installed, thereby losing the capability to deploy Sidewinders, though.
Among other things, the machines were furthermore upgraded with new bird strike-proof cockpit glazing, avionics were modernized, and several other minor customer requests were adopted, like a 0.6-megacandela night identification light. This spotlight is mounted in the former portside gun bay in front of the cockpit, and an anti-glare panel was added under the windscreen.
The fixed in-flight refueling probe was deleted, as this was not deemed necessary anymore since the Lightnings would exclusively operate within neutral Austria’s borders. The probes could, however, be re-installed, even though the Austrian pilots would not receive on-flight refueling training. The Lightnings' optional 260 imp gal overwing tanks were retained since they were considered to be sufficient for extended subsonic air patrols or eventual ferry flights.
The refurbished Lightnings were re-designated F.56 and delivered in batches of four between 1987 and 1989 to the Austrian Air Force’s 1st and then 2nd Fighter Squadrons, carrying a grey air superiority paint scheme. At that time, the airframes had between 1,550 and 2,800 flight hours and all had a general overhaul behind them. In 1991, the Lightings were joined by eighteen German ex-NVA-LSK MiG-23s, which were transferred to Austrian Air Force's ‘Fliegerwerft B’ at Nittner Air Base, where they'd be overhauled and updated with NATO-compatible equipment. As MiG-23Ö they were exclusively used as interceptors, too.
Shortly after their introduction, the Austrian Lightnings saw their first major use in airspace interdiction starting 1991 during the Yugoslav Wars, when Yugoslav MiG-21 fighters frequently crossed the Austrian border without permission. In one incident on 28 June a MiG-21 penetrated as far as Graz, causing widespread demands for action. Following repeated border crossings by armed aircraft of the Yugoslav People's Army, changes were suggested to the standing orders for aircraft armament.
With more and more practice and frequent interceptions one of the Lightning's basic flaws became apparent: its low range. Even though the Lightning had a phenomenal acceleration and rate of climb, this was only achieved in a relatively clean configuration - intercepting intruders was one thing but escorting them back to the Austrian border or an assigned airfield, as well as standing air patrols, were a different thing. With more tactical experience, the overwing tanks were taken back into service, even though they were so draggy that their range benefit was ultimately zero when the aircraft would use its afterburners during a typical interception mission. Therefore, the Austrian QRA Lightnings were typically operated in pairs: one clean and only lightly armed (typically with the guns and a pair of AIM-9s), to make a quick approach for visual intruder identification and contact, while a second aircraft with extra fuel would follow at high subsonic speed and eventually take over and escort the intruder. Airspace patrol was primarily executed with the MiG-23Ö, because it had a much better endurance, thanks to its VG wings, even though the Floggers had a poor service record, and their maintenance became ever more complicated.
After more experience, the Austrian Lightnings received in 1992 new ALR-45 radar detectors in a fairing on the fin top as well as chaff and flare dispenser systems, and the communication systems were upgraded, too. In 2004 the installation of Garmin 295 moving map navigation devices followed, even though this turned out to be a negligible update: on December 22, 2005, the active service life and thus military use of the Lightnings in general ended, and Austria was the last country to decommission the type, more than 50 years after the first flight of the prototype on August 4, 1954.
The Austrian Lightnings’ planned service period of 10 years was almost doubled, though, due to massive delays with the Eurofighter’s development: In 2002, Austria had already selected the Typhoon as its new “Phase II” air defense aircraft, having beaten the F-16 and the Saab Gripen in competition, and its introduction had been expected to occur from early 2005 on, so that the Lightnings could be gradually phased out. The purchase of 18 Typhoons was agreed on 1 July 2003, but it would take until 12 July 2007 that the first Typhoon would eventually be delivered to Zeltweg Air Base and formally enter service with the Austrian Air Force. This operational gap had to be bridged with twelve F-5E leased from Switzerland for EUR 75 mio., so that Quick Reaction Alert (QRA) duties for the Austrian airspace could be continued.

The kit and its assembly:
This was another submission to the “Hunter, Lightning and Canberra” group build at whatifmodellers.com in 2022 and intended as a rather simple build since it was based on an alternate reality plot: the weird story that Austria was offered a revamped fleet of ex-Saudi Arabian Lightnings is true(!), but the decision eventually fell in favor of revamped Saab J 35Ds from Sweden. For this what-if build I used the real historic timeline, replaced the aircraft, and built both story and model around this – and the result became the BAC Lightning F.56 in Austrian Air Force service.
Initially I wanted to use an Airfix BAC Lightning in The Stash™, a really nice model kit and a relatively new mold, but it turned out to be the kit’s F.2A variant. While very similar to the F.6, changing it into a F.53 analogue with the OOB parts turned out to be too complex for my taste. For instance, the F.2A kit lacks the ventral gun bay (it just comes with the auxiliary tank option since the guns are already located in front of the cockpit) and the cable conduits on the lower flanks. Procuring a suitable and priceworthy Airfix F.6 turned out to be impossible, but then I remembered a Hasegawa Lightning F.6 in The Stash™ that I had shot at ev!lbay many moons ago for a laughable price and without a concrete plan. However, this kit is pretty old: it has raised (yet quite fine, less robust than the Matchbox kit) panel lines and even comes with a pilot figure, but also many weak spots like the air intake and the jet exhausts that end in flat walls after some millimeters depth and a very basic cockpit. But for this rather simple what-if project the kit appeared to be a suitable basis, and it would eventually find a good use.
The Hasegawa Lightning was basically built OOB, even though I made some cosmetic amendments like a better seat for the pilot, hydraulic fluid lines on the landing gear made from wire or opening the flat walls inside of the air intake opening and the jet nozzles. Behind the radome, a simple splitter plate was added as well as a recessed bulkhead in front of an implanted Me 262 cockpit tub (the Hasegawa kit just offers a bare floor panel, nothing else!), the afterburners were extended inwards with parts from a Matchbox A.W. Meteor night fighter.
The Red Top AAMs and the in-flight refueling probe were omitted. Instead, I added extra F.53-style forward-swept pylons under the outer wings, scratched from 1.5 mm styrene sheet due to their odd, raked shape, and I added Sidewinder launch rails plus suitable missiles from a Hasegawa air-to-air weapons set to all four stations. After long consideration I also retained the ‘overburger’ tanks, partly because of the unique layout on the Lightning, and also because of operational considerations.
Chaff dispensers were scratched from styrene profiles and placed at the fin’s base. A fairing for the retrofitted radar warning sensor was added to the fin tip, created from 1.5 mm styrene sheet.
Painting and markings:
To reflect the “alternate reality” role of the Lightning I gave the model a livery similar to the Saab J 35Ö that were actually procured: an adaptation of the USAF “Egypt One” scheme, carried primarily by the USAF F-16s. Adapting this simple three-tone camouflage from the flat F-16 to the Draken was easy and straightforward, but applying it to a Lightning with its many vertical surfaces turned out to be a tough challenge. I eventually came up with a paint scheme that reminds of the late RAF low-viz Lightning liveries, which existed in a wide range of patterns and graduations of grey.
The colors were authentic, FS 36118, 36270 and 36375 (using Humbrol 125, 126 and 127), and I decided to emphasize the camouflage of the flanks against the horizon, so that the vertical surfaces and the fin became FS 36270. The undersides of wings, stabilizers and fuselage became FS 36375. The dark FS 36118 was only applied to the upper sides of the wings and the stabilizer, and to a high dorsal section, starting at the wing roots. As a small contrast, the tank area on the spine was painted in light grey, simulating unpainted fiber glass. The radome was painted with a streaky mix of Humbrol 155 and 56.
As usual, the model received a light black ink washing, some post-panel-shading in lighter tones, and, due to the raised panel lines, was very lightly rubbed with graphite. The cockpit interior was painted in medium grey (Revell 47) with an olive drab fabric fairing behind the black pilot seat, which received ejection handles made from thin wire as eye candy. The landing gear and the respective wells were painted in Humbrol 56 (Aluminum Dope).
The decals are a wild mix: The fuselage roundels are actually wing markings from a Hasegawa J 35OE, as well as the huge orange "06" on the wings (I could not resist; they will later be partly obscured by the overwing tanks, but the heck with it!). The roundels on the wings come from a generic TL Modellbau sheet - I found that I needed larger markings than those on the Draken.
Both unit and individual aircraft identifiers are single black DIN font digits, also from TL Modellbau. The unit badges on the fin are authentic, even though from an earlier era: they came from an Austrian J 29 of Fliegerregiment 2 from a PrintScale sheet, and all stencils were taken from the OOB low-viz RAF markings sheet, plus four small warning triangles for the underwing pylons.
A ‘what-if’ model in the purest sense, since this model depicts what could really have been: ex Saudi-Arabian export BAC Lightnings over the Austrian Alps! However, refurbished Saab J 35D Draken made the race (and later followed by the Eurofighter Typhoon at ‘Stage 2’), so that this Lightning remains fictional. It does not look bad in the ‘Egypt One’ paint scheme, though, better than expected!

Designed in 1946 to answer Soviet premier Joseph Stalin's urgent call for a high-altitude day interceptor, the MiG-15 was destined to shock the West with its capabilities and make the acronym "MiG" synonymous with "Soviet fighter plane." It was the first Soviet jet to benefit from the British sale to Russia of the new Rolls Royce "Nene" and "Derwent" jet engines. These were immediately copied and refined by the Soviets, and as the RD-500, Klimov RD-45 and modified VK-1, they gave a powerful boost to Soviet jet technology.
First flown on December 30, 1947, the MiG-15 featured the first production swept wing on a Russian aircraft, the first pressurized cockpit, and the first ejection seat. Although Mikoyan and Gurevitch were aware of German turbojet and swept-wing work, this design was wholly Russian--except for the engine. The Cold War had just begun and Stalin was readying the B-29 clone, the Tu-4, and was developing the atomic bomb, both in high-priority programs. MiG-15 production was authorized in March 1948, only 3 months after first test flight, and substantial numbers were in service by the end of 1948 with the both Soviet Air Forces (VVS, the tactical air arm) and IA-PVO (the air defense arm).
Late in 1950, MiG-15s piloted by Russians appeared over North Korea, and their prowess "shocked and stunned" Americans. Their deadly attacks, using one 37mm and two 23mm cannon, quickly ran all piston-engined aircraft from the skies, including the B-29. First generation jets like the F-80 and F-84 were no match, and America had to rush the F-86 into Korea to reestablish air superiority. Despite its high speed, excellent maneuverability, and high service ceiling, the MiG-15 was not very stable as a gun platform, with a tendency to Dutch roll at high speeds because of wing flexing and poor aileron effectiveness. Its cockpit instrumentation was primitive and stick forces were heavy. In combat against the F-86, a much more advanced fighter but with very similar performance, the MiG-15 suffered a 10:1 loss ratio.
Russians were joined by Chinese and North Korean MiG-15s before the Korean War ended, and the MiG-15 was ultimately flown in some 35 countries, remaining in service in China as late as 1978, where it was called the J-2 (F-2 in an export version). The MiG-15UTI trainer version, also used throughout the world, is still in common service today. More than 12,000 MiG-15s were built in 17 versions, in Poland, Czechoslovakia, and China, as well as in the USSR. Many Chinese F-2s have made their way to the United States, where they can be seen in flight displays at air shows. Based on lessons of the Korean combat, the MiG-15 was later upgraded as the MiG-17, which also served throughout the world, including combat in Vietnam and the Middle East.
The MiG-15 on display at the National Air and Space Museum, serial number 4320, is a Chinese F-2, acquired in September 1985 through an exchange with the Champlin Fighter Museum, Mesa AZ. There is no record of its production or service history before the aircraft's arrival in the U.S. Source: airandspace.si.edu/collection-objects/mikoyan-gurevich-mi...

More and more owners of Canon PowerShot cameras have found CHDK, which is a firmware hack that allows users to add a lot of additional capabilities to their cameras. The capabilities include faster and slower shutter speeds, addition of RAW format, increased aperture range, better histograms, battery monitors, and user control scripts. I'm not going to discuss how to install CHDK or any scripts here. The links in these instructions (and the discussions in the Canon PowerShot S5 IS Group provide lots on good information on how to do that.)
UPDATE: (31 August 2008) The newer Juciphox Build of CHDK allows for the remote to work without additional scripts. In my initial testing, this version is much simpler to use than the older script-based technique.
One of the scripts available to CHDK users adds the capability to remotely trip the shutter using the camera's USB port. Before you read any further, please note that while most things that you can do with CHDK cannot harm your camera, applying too much power to the USB port on your camera can cause major damage that Canon will charge you an enormous amount of money to repair. This is a fairly easy hack if you own a multimeter and a soldering iron, but if the thought of wiring a homemade device into your beautiful little camera and risking the possibility of causing it go KABLOOEY makes you feel uneasy, then this may not be the project for you. IF YOU FOLLOW THESE INSTRUCTIONS, YOU DO SO AT YOUR OWN RISK.
There are some great webpages that explain the process of building and using a USB remote trigger, including the script itself. Since a remote trigger is great for long exposure and macro photography, I decided to build it for myself. I followed the instructions, but it didn't work. I could trip the shutter by running the script and connecting the camera to a laptop via the USB cable, but not when my trigger was connected. I tested and retested it, but nothing would make it work. Finally, I found this page that indicated that unlike the S2 IS and S3 IS, the S5 needs at least 3.7V to trigger instead of the 3V that would trigger the earlier cameras. So, I rebuilt the remote to use 4.5V (using a 3V CR2032 watch battery and a 1.5V "Type N" alkyline battery) , and it immediately worked like a charm.
I bought all of the components at Radio Shack (and the part numbers listed below are their part numbers, this isn't an add for them, they are just the only place in my small town that sells this type of stuff). The case is a 270-1801 Project Enclosure ($2.29), which is 3x2x1 inches (7.5x5x2.5 cm). The momentary push button switch is part number 275-646 ($2.49). It is mounted in the case with a 1/2 inch hole. I also routed out a small hole with a Dremmel tool on a corner opposite the switch so that the USB cable could exit the case once the lid is screwed back on.
I cut a spare USB extension cable with "Type A" ends (i.e., with a plug on one end and a receptacle on the other). I stripped back part of the cable on the receptacle end and found the wires corresponding to pins 1 and 4 using a multimeter.
To generate enough power in such a small enclosure, I ended up using both a 3V CR2032 battery and a 1.5V "N" alkaline battery. The battery holders for these are part numbers 270-0009 for the CR2032 ($0.99), and 270-405A for the N battery ($0.99). I soldered the black wire from the N battery holder to the "+" connector post on the CR2032 holder. I then soldered the red wire from the N battery holder to one post of the switch. I then soldered another length of red wire to the other post of the switch, and a length of black wire to the "-" post of the CR2032 holder.
I attached all of the battery holders to the inside of the case using double-sided tape.
FInally, I soldered the red wire from the switch and the black wire from the CR2032 enclosure to the wires corresponding to pins 1 and 4 respectively on the USB receptacle cable that I cut earlier. I then taped up these soldered connections with electrical tape and packed them into the case as neatly as I could. After screwing the cover back on, I tested the switch with a multimeter to verify that pins 1 and 4 of the USB receptacle showed approximately 4.5V (but under no circumstances more than 5V !) when the button was depressed.
Once this was done, I connected it to my camera with a Type A to Mini-B USB cable, turned on the camera, started the remote shutter CHDK script, and my new remote worked perfectly!
I chose to use a Type A receptacle with a short cable on my remote. Some may prefer wiring a Mini-B type plug directly, but this method provides me with more flexibility. The short cord makes it easier to carry and store, and allows me to connect a short USB cable (which I carry in my bag), or a long one (which I don't) depending on what I'm going to do. It's also a lot easier to test the contraption during construction with the larger end than it would have been with the Mini-B.
I built this remote for about $6.75 (plus about $8 for the batteries!). I was also able to use a USB cable that I already had. Local businesses were all really proud of their USB cables, but they can be purchased pretty inexpensively on the web.
Finally, if you don't want to use an "N" battery, any 1.5V battery will work. AA or AAA batteries would work fine, but I didn't have room in my case to use them.
UPDATE (15 September 2008): I have now built a second trigger with a larger case that uses three AAA batteries and that has a larger button for use by people with limited manual dexterity.
The capabilities of the Auto S3’s unique daylight Synchro/Flash System can be exploited to provide metered manual control. In daylight (non-flash) mode, aperture setting is electrically determined by the primary meter needle responding to ambient light.
As a flash unit is slipped into the hot shoe, a mechanical sensor pin (A-F Switchover) in the right side of the hot shoe is tripped placing the camera into flash photography mode where aperture setting is decoupled from the meter. The meter continues responding to changes in ambient light in flash mode but no longer plays a role to determine aperture setting. In flash mode, aperture blades are set mechanically as the camera is focused, as can be seen from the front of the taking lens and indicated in the finder by the green synchro flash bar. After focus, aperture can be manually altered + or - using the guide number setting ring. Shutter speed is always set manually.
Enter manual aperture control mode by inserting a flash unit that is switched ‘off’, or a hot shoe cover that can trip the A-F Switchover Pin. Aperture setting is then mechanically controlled by focus and manually altered by the guide number (GN) ring.
The meter is active in flash mode providing metered manual mode.
After the acquisition of the Pbv 501, the Nordic Union discovered that despite it's strong capabilities the IFV also suffered from a wide variety of flaws that could result in catastrophic damage to the vehicle and crew when penetrated.
It was therefore decided to construct an improved version of the vehicle, switching out the Pbv 501's 73m gun with a 30mm autocanon. This weapon wasn't able to effectively engage tanks like the previous one, but was better suited to defeat infantry and lightly protected AFVs. The 30mm's lack of a strong HEAT shell is made up by the anti-tank missile launcher attached to the top of the turret. Furthermore, this removel of shells for the 73mm gun dramatically lowered the risk of an ammunition cook-off.
The Pansarbandvagn 502 was given more armor on the bottom plate to better protect from mines and the turret is now a two-man configuration.
Finally, there are other small improvements such as mirrors for the drivers and smoke grenade dispensers attached to the turret.

Cyber security is strongest when engineered into our systems versus designing cyber security protections later. That is why we design all aircraft, and their supporting systems, to operate in a cyber contested environment.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 "Raptor" is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 "Eagle" and F-16 "Fighting Falcon". Code named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 "Flanker"- and MiG-29 "Fulcrum"-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 "Eagle" and F-16 "Fighting Falcon" or the newer F-35 "Lightning II", which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35's delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35's strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22's price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G "Growler". Issues with the F-22's reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35's capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP).[66] A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D. To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35's.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 "Raptor" is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22's thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22's high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22's thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22's aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22's exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22's mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 "Phantom II" that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.

From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 "Flanker"- and MiG-29 "Fulcrum"-class of fighter aircraft.

In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP).[66] A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D.[83][84] To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35's.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22's thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22's high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22's thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22's aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22's exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22's mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.
