In the Netherlands, the drainage system is an important matter. The Dutch need a well developed water control system in order to keep large areas from being flooded, because some parts of the Netherlands are below sea level. In Alblasserwaard, problems with water became more and more apparent in the 13th century. Large canals, called 'weteringen', were dug to get rid of the excess water in the polders. However, the drained soil started setting, while the level of the river rose due to the river's sand deposits.
The Kinderdijk Windmills in the Netherlands are an UNESCO World Heritage Site.

AKSM-32100D is a trolleybus with a transistorized control system based on IGBT modules and an AC induction motor, equipped with accumulators based on lithium-iron-phosphate batteries with a reserve of autonomous travel up to 30 kilometers. Unlike base model AKSM-32100, it is equipped with a 150 kW traction motor. The first three ones were delivered to Ulyanovsk, Russia at the end of 2015. In 2016-2019 St. Petersburg received 35 ones, others were delivered to Belarus cities (5 to Grodno, 4 to Gomel, 4 to Vitebsk). In 2021, they were delivered to Belarus capital Minsk (25 ones) and Vratsa (9). In December 2021, three more restyled trolleybuses came to Grodno to operate the new route 24.
АКСМ-32100D trolleybuses are produced by the Belarus company Belkommunmash (BKM; Производственное Объединение «Белкоммунмаш», БКМ). BKM was organized in 1973 on the basis of the streetcar and trolleybus repair shop under the Ministry of Municipal Economy of the Belarusian Soviet Socialist Republic. During the first two decades the plant was repairing trolleybuses and streetcars of Minsk. After USSR breakage the independent Belarus got a strong incentive to develop its own vehicles production. Therefore a few articulated trolleybuses YMZ T1 (ЮМЗ Т1) were assembled at the plant in 1993 from engineering sets of Yuzhny Machine Building Plant of Ukraine. The enterprise also modernized trolleybuses of the ZIU models 100 - 101 produced by the Engels Electric Transportation Plant (later CJSC "TrolZa") in Engels, Saratov region of Russia. Later the company started to develop its own trolleybus models, the first model AKSM 201 (АКСМ 201) appeared in 1996, followed by models 213, 221, 321 (as in foto) and 333. Since 2000 the production of streetcars started: AKSM-1M, AKSM-60102. In 2016, the production of electric buses has been organized. Today the BKM Holding (ОАО «Управляющая компания холдинга «Белкоммунмаш» - ОАО «УКХ «БКМ) is the leading industrial enterprise in Belarus in the field of production and overhaul of rolling stock of urban electric transport.
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.
Shepard named his space capsule Freedom 7, setting a precedent for the remaining six Mercury astronauts naming their spacecraft. The number 7 was included in all the crewed Mercury spacecraft names to honor NASA's first group of seven astronauts. His spacecraft reached an altitude of 101.2 nautical miles (116.5 statute miles, 187.5 km) and traveled a downrange distance of 263.1 nautical miles (302.8 statute miles, 487.3 km). It was the fourth Mercury flight launched with the Mercury-Redstone Launch Vehicle,[Note 1] from Cape Canaveral, Florida, close to the Atlantic Ocean.
During the flight, Shepard observed the Earth and tested the capsule's attitude control system, turning the capsule around to face its blunt heat shield forward for atmospheric re-entry. He also tested the retrorockets which would return later missions from orbit, though the capsule did not have enough energy to remain in orbit. After re-entry, the capsule landed by parachute on the North Atlantic Ocean off the Bahamas. Shepard and the capsule were picked up by helicopter and brought to U.S. Navy aircraft carrier USS Lake Champlain.
The mission was a technical success, though American pride in the accomplishment was dampened by the fact that just three weeks before, the Soviet Union had launched the first human in space, Yuri Gagarin, who completed one orbit on Vostok 1. In 2017 the first National Astronaut Day was held on May 5 to pay tribute to this first U.S. flight.

It's twilight for this Chicago & North Western searchlight signal in more ways than one. The eastbound absolute signal at Nachusa, IL is likely in its last few months of service, before Union Pacific replaces this interlocking with a microprocessor control system and the inevitable modern color light signals.
At the time it was installed in the late Forties, this 75-mile stretch of CTC was the longest stretch of CTC on two continuous main tracks. Nachusa was the eastern end of the Lee County Cut-off, a bypass route that allowed tonnage trains to avoid the trip through Dixon, particularly the climb out of the Rock River valley. The long-abandoned cutoff converged with the two main tracks out of frame to the right.
The North Western was one of a handful of railroads that used an outsized background for their searchlights instead of the typical circular background. No reason has been recorded for this choice, but it was a recognizable trait of C&NW searchlights from a particular era.
These plug and play remote control systems that have become more prevalent on shortlines in recent years sure do mar the looks of the locomotive. But if that's what it takes to keep these classic dinosaurs running and pulling frieght I'm ok with it!
Anyway, we tried to at least see each of the four Arkansas and Missouri Railroad jobs on duty from Springdale the day we set aside to visit. I already shared one shot of the SMTN road train with the SD70ACEs and several of the SFLO Springdale local. While we would spend most of our day with the latter we did at least see the other two jobs. Here is the Sand Remote job which was on duty at 0700 that we found out near the end of the short Bentonville branch which now only extends from Rogers only about 3.5 miles to the Bentonville line but prior to 1940 reached about 45 miles to Grove, OK. The job was found west of the North 24th St. crossing slowly dumping sand cars at the SMG Materials pit. Sole power was AM 32 an Alco C424 blt. Apr. 1965 as Belt Railway of Chicago 601.

The Northrop M2-F3 was a heavyweight lifting body rebuilt from the Northrop M2-F2 after it crashed at the Dryden Flight Research Center in 1967. The "M" refers to "manned" and "F" refers to "flight" version.
Early flight testing of the M2-F1 and M2-F2 lifting body re-entry configurations had validated the concept of piloted lifting body re-entry from space. When the M2-F2 crashed on 10 May 1967, valuable information had already been obtained and was contributing to new designs.
NASA pilots said the M2-F2 had lateral control problems, so when it was rebuilt at Northrop and redesignated the M2-F3, it was modified with an additional third vertical fin - centred between the tip fins - to improve control characteristics.
After a three-year-long redesign and rebuilding effort, the 2.3-tonne (empty) M2-F3 was ready to fly. The May 1967 crash had torn off the left fin and landing gear. It had also damaged the external skin and internal structure. Flight Research Center engineers worked with Ames Research Center and the Air Force in redesigning the vehicle with a centre fin to provide greater stability. At first, it seemed that the vehicle had been irreparably damaged, but the original manufacturer, Northrop, did the repair work and returned the redesigned M2-F3 with a centre fin for stability to the FRC.
While the M2-F3 was still demanding to fly, the centre fin eliminated the high risk of pilot induced oscillation (PIO) that had been characteristic of the M2-F2.
First flight of the M2-F3, with NASA pilot Bill Dana at the controls, was 2 June 1970. The modified vehicle exhibited much better lateral stability and control characteristics than before, and only three glide flights were necessary before the first powered flight on 25 November 1970. The 100th flight of the heavyweight lifting bodies was completed on 5 October 1972, with pilot Bill Dana soaring to an altitude of 20,200m and a Mach number of 1.370 in the M2-F3. Over its 27 missions, the M2-F3 reached a top speed of 1,064 mph (Mach 1.6). Highest altitude reached by the vehicle was 20,790m on 20 December 1972, the date of its last flight, with NASA pilot John Manke at the controls.
A reaction control thruster (RCT) system, similar to that on orbiting spacecraft, was also installed to obtain research data about their effectiveness for vehicle control. As the M2-F3's portion of the lifting body programme neared an end, it evaluated a rate command augmentation control system, and a side-arm control stick similar to side-arm controllers now used on many modern aircraft.
NASA donated the M2-F3 vehicle to the Smithsonian Institution in December 1973. It is seen above hanging in the foyer of the National Air and Space Museum on the Mall in Washington DC. - details from Wikipedia.

47749 "City of Truro" - 5Q87 (1013 MO Ferme Park Reception Line - Worksop Down Yard via Toton, which was formed of unit 387101 [to be fitted with European Train Control System or ETCS at Derby]) - Welwyn North - 1042 (1 late) - 24/10/22.
After leaving home late & getting delayed by roadworks in Hertford, this train was already at Welwyn Garden City when I arrived (the 20 minutes only parking until 1100 is a pain in the xxxx).
Class 89, No.89001 at the Greatest Gathering at Derby
The British Rail Class 89 is a prototype electric locomotive.
This is the only one that was built, in 1986, by British Rail Engineering Limited's Crewe Works. It was used on test trains on both the West Coast and East Coast Main Lines. The locomotive was fitted with advanced power control systems and developed more than 6,000 bhp (4,500 kW). After being withdrawn in 1992, it was returned to service in 1996, before being again withdrawn in 2000. As of January 2021, it is in the final stages of an overhaul that will return it to the main line.
In October 2006 GNER put 89001 up for sale, with a six-week deadline for bids. The AC Locomotive Group launched an appeal and fundraising effort to save the locomotive, which was ultimately successful, and purchased it in December 2006. The locomotive was mostly complete, although a number of major components required expensive overhaul before it could run on the main line again. A thorough survey was undertaken to establish exactly what was required and costs drawn up. Cosmetic work in 2007 saw the loco return to its original InterCity Executive colour scheme. Electrical restoration work focused on repairing and/or refurbishing the items that led to the locomotive being withdrawn from service, namely the traction motors and their associated field converter electronics. The locomotive was lifted by Harry Needle Railroad Company at Barrow Hill Engine Shed in December 2010 and three traction motors were removed, including the one known to be faulty. In February 2011 these were being examined at Bowers to allow repair cost estimates to be made. Two of the field converters were removed, one being faulty, and again repair estimates were sought. Initially it was intended, as funds became available, to allow one power group (i.e. one bogie) to become fully operational.
On 30 April 2020 the locomotive was moved from Barrow Hill Engine Shed to Toton TMD to be repainted. It was outshopped in Intercity Swallow Livery. In October 2020 it was hauled to Soho TMD for testing.
In December 2021, the AC Locomotive Group announced it had formed a new partnership with Locomotive Services Limited (LSL) that would see the remaining tasks in the overhaul completed and 89001 returned to the mainline. Once complete, it will operate with LSL for five years.
A northbound sand extra was zipping through Mount Prospect just as the afternoon sun was swinging around to an almost-acceptable angle. SD40N 1999 leads the way; the 'N' part of the designation comes from UP's use of the NEXSYS control system from ZTR Control Systems, replacing the older Dash 2 component cards and control systems.
This is a close-up view of the forward port-side reaction control system (RCS) on the Space Shuttle Discovery.
Each RCS (two forward and two aft) consists of high-pressure gaseous helium storage tanks, pressure regulation and relief systems, a fuel and oxidiser tank, a system that distributes propellant to its engines, and thermal control systems (electrical heaters). They provide the thrust for attitude (rotational) manoeuvres (pitch, yaw and roll) and for small velocity changes along the orbiter axis (translation manoeuvres).
Around them you can see some of the multitude of individually-labelled differently sized and shaped tiles giving the Shuttle its thermal protection, so necessary for successful re-entries into the atmosphere.
I was lucky enough to turn up (by accident) at the Udvar-Hazy Center on the day that Discovery was first unveiled to the public.
Loading of an Erieye radar antenna. The Erieye radar system, is an Airborne Early Warning and Control System (AEW&C) developed by Saab Electronic Defence Systems (formerly Ericsson Microwave Systems) of Sweden. It uses active electronically scanned array (AESA) technology. The Erieye is used on a variety of aircraft platforms, such as the Brazilian Embraer E-99 or EMB-145. It has recently been implemented on the Saab 2000 aircraft.
The Erieye Ground Interface Segment (EGIS; not to be confused with the Aegis combat system) is a major component of the software used by the Erieye system.
The radar provides 300 degree coverage and has an instrumental range of 450 km and detection range of 350 km in a dense hostile electronic warfare environment—in heavy radar clutter and at low target altitudes.

An Air Force Lockheed Martin F-22 "Raptor" assigned to the 3rd Wing flies over Joint Base Elmendorf-Richardson, Alaska, Feb. 27, 2018. The Lockheed Martin F-22 "Raptor" is the U.S. Air Force’s premium fifth-generation fighter asset.
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. 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.

First things first, most of the gunship's structure is based off another gunship MOC which definitely looks more cleaner but hey, I'm happy that I have one.
Originally did try to make the original but due to insufficient pieces from a seller I like to buy bricks from, I decided it was best to not spend too much for one model by buying from multiple sellers.
First thing you'll point out is the it's a single pilot (Single cockpit) and well, there's some bricknical issue trying to inplement the second one so scrapped it out with some wedge pieces for a somewhat nice finishing. There is a 'control system' just right under the cockpit which is used to control the front 2 laz0r guns roar :v.
Doors can slide open :3 but it doesn't have that second hinge to keep it in place if you know what I mean?
On top of the Gunship is a storage for 4 crates :)), opening on the far backside top for a gun or two and there's two post box or whatever on the sides near the back of the ship and a back door cause why not.
Can carry up to 9 figs including the pilot and maybe 10 if you want it pakced inside. If you want to fly it around :3 (me) then holding the underside is the most safetest way for me since the wing's hinge is a bit weak so underside to be safe. And that's it.
Probably the most difficult process of building is the backside since the MOC am copying from is blinded to my view so I had to improvise the design and tada. It's made and I love it. Had always wanted one. Now I think I'd go buy some same color brick set to make a much more neat design when I have the money :))

AKSM-32100D is a trolleybus with a transistorized control system based on IGBT modules and an AC induction motor, equipped with accumulators based on lithium-iron-phosphate batteries with a reserve of autonomous travel up to 30 kilometers. Unlike base model AKSM-32100, it is equipped with a 150 kW traction motor. The first three ones were delivered to Ulyanovsk, Russia at the end of 2015. In 2016-2019 St. Petersburg received 35 ones, others were delivered to Belarus cities (5 to Grodno, 4 to Gomel, 4 to Vitebsk). In 2021, they were delivered to Belarus capital Minsk (25 ones) and Vratsa (9). In December 2021, three more restyled trolleybuses came to Grodno to operate the new route 24.
АКСМ-32100D trolleybuses are produced by the Belarus company Belkommunmash (BKM; Производственное Объединение «Белкоммунмаш», БКМ). BKM was organized in 1973 on the basis of the streetcar and trolleybus repair shop under the Ministry of Municipal Economy of the Belarusian Soviet Socialist Republic. During the first two decades the plant was repairing trolleybuses and streetcars of Minsk. After USSR breakage the independent Belarus got a strong incentive to develop its own vehicles production. Therefore a few articulated trolleybuses YMZ T1 (ЮМЗ Т1) were assembled at the plant in 1993 from engineering sets of Yuzhny Machine Building Plant of Ukraine. The enterprise also modernized trolleybuses of the ZIU models 100 - 101 produced by the Engels Electric Transportation Plant (later CJSC "TrolZa") in Engels, Saratov region of Russia. Later the company started to develop its own trolleybus models, the first model AKSM 201 (АКСМ 201) appeared in 1996, followed by models 213, 221, 321 (as in foto) and 333. Since 2000 the production of streetcars started: AKSM-1M, AKSM-60102. In 2016, the production of electric buses has been organized. Today the BKM Holding (ОАО «Управляющая компания холдинга «Белкоммунмаш» - ОАО «УКХ «БКМ) is the leading industrial enterprise in Belarus in the field of production and overhaul of rolling stock of urban electric transport.
The rainwater rushing down from majestic Ko'olau Mountain on the windward side of Oahu in 1965 and 1969 caused major devastation to the inhabitants of Kâne'ohe on the coast with the loss of many homes. The United States Army Corps of Engineers was ordered to set up a flood control system. Part of this system was the laying out of a huge botanical garden called Ho'omaluhia (= making a place of peace and tranquillity). The 400-acre garden lives up to this name splendidly. It opened its gates in 1982, and is now one of the five Honolulu botantical gardens. It is indeed a magnificent, quiet place and a haven to many species of plants, some of which are severely endangered.
In the section of the garden called Kahua Lehua (=native Hawai'ian plants) I saw this delicate, native Hawai'ian hibiscus, labeled as Koki'o ke'oke'o and, in Latin, Hibiscus waimeae. It was first fully described in 1897 by Amos Arthus Heller (1867-1944), who early in his career visited Hawai'i. He later went on to become a major expert on and collector of Puerto Rican plants. There's a bit of confusion in the literature whether this hibiscus is the same as the White Kaua'i Rosemallow. If anyone can clear this up for me, please write!

Airmen assigned to the 95th Aircraft Maintenance Unit, Tyndall Air Force Base, Fla., launch Lockheed Martin F-22 "Raptor" aircraft during exercise Combat Archer at Hill Air Force Base, Utah, Aug. 18, 2016.
HILL AIR FORCE BASE, Utah -- Military exercises Combat Hammer and Combat Archer ended August 18 at Hill AFB and the Utah Test and Training Range.
During the exercises, Total Force Initiative Airmen assigned to the active-duty 95th and AF Reserve 301st Fighter Squadrons from Tyndall AFB, Fla. tested their ability to build, load, launch and employ munitions, which were dropped and fired from Tyndall Lockheed Martin F-22 Raptor aircraft.
“Our Airmen gain a tremendous opportunity to prepare for future combat operations in the F-22 by performing in these exercises,” said Lt. Col. Daniel Lehoski, 95th Fighter Squadron detachment commander. “It builds confidence in our team, aircraft, and munitions through a mission-focused effort.”
The air-to-ground and air-to-air exercises are conducted by the 83rd and 86th Fighter Weapons Squadrons here. Their purpose is to collect and analyze data on the performance of precision weapons, and to measure their suitability for use in combat.
During the exercises, Lehoski noted that Tyndall F-22s dropped 32 precision guided munitions, employed 14 air-to-air missiles, and validated AIM-9X missile employment procedures, a first for Tyndall F-22s. Operations Airmen also flew integration missions with F-35, F-16, and F-15E aircraft, enhancing their ability to provide air dominance for America.
“We are tremendously appreciative of the support we have received from Hill AFB and both the 86th and 83rd FWS for giving the Airmen of Team Tyndall the opportunity to train at Combat Hammer and Combat Archer,” said Lehoski.
Airmen and aircraft, including A-10s from Moody AFB, Ga., F-15Es from Royal Air Force Lakenheath, England, and F-16s from Shaw AFB, S.C., also participated during the past two weeks.

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.[60] 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.[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.
.................................................................................................
Before getting into A, B, and C differences for the F-35, a short primer on how to tell an F-35 from an F-22 may help avoid an even larger fighter faux pas. After all, the F-22 and F-35 look similar as well, especially from certain angles and at a distance. Both the F-22 and F-35 have two intakes, two tails, and similar planforms.
If the two aircraft happen to be parked together, the F-22, however, is noticeably larger. The Raptor is about ten feet longer than a Lightning II. Its wingspan is about ten feet wider than an F-35A’s and F-35B’s, and roughly the same as an F-35C’s.
From behind, the twin, rectangular thrust-vectoring exhaust nozzles on the F-22 are an obvious difference. The F-35 has one round exhaust nozzle for its single engine. The geometry of the engine intakes distinguishes the two aircraft from the top and side. The Raptor’s intakes angle back. On the Lightning II, they point forward. Intake differences are visible from the front view as well. Opposing sides of the F-22’s intakes are parallel. The corners are slightly rounded. The F-35’s intake angles are sharper. A space between the intake and the fuselage, called a diverter, is found only on the Raptor as well. The F-35’s diverterless intake sits flush to the fuselage.
The single- vs. twin-engine difference plays out on the top sides of the two aircraft as well. The F-22 has two humps between the tails. The F-35 has just one. On the underside, the F-22 is much flatter with one main (though split) weapon bay with two doors. The F-35 is more rounded and has two distinct main weapon bays each with two doors. Taxiing, the F-22 sits about a foot lower than an F-35.
Context also matters. If the airplane in question is operating from an aircraft carrier, landing vertically, taking off in a very short distance, or displaying non-USAF markings, it’s not an F-22.
Context And The F-35 Variants
When it comes to distinguishing among F-35 variants, context can provide some tips as well. If the F-35 in question is being catapulted from a carrier, it’s an F-35C. If it’s landing vertically, it’s an F-35B. If it has Royal Air Force markings, it’s an F-35B. If it has international markings that aren’t associated with the RAF, it’s an F-35A (at least until another international air force procures B or C models).
Basic A, B, & C Differences
The A model is most easily distinguished from other F-35 models by the blister on the upper left side for its internal GAU-22/A Gatling-type gun. (B and C models do not have internal guns.) Like the B model, the F-35A has a smaller wing. The A model is the only F-35 variant with a refueling receptacle on its dorsal spine. The receptacle markings are clearly visible from the top view.
The B model is most easily distinguished from other F-35 models by its vertical lift system. The system comes into play at almost every viewing angle of the aircraft. Even in up-and-away (non vertical) flight, the F-35B has visual clues for the vertical lift system. The lift fan door flattens the upper surface of the F-35 just behind the cockpit, giving this model a distinctive hump. The hump is especially noticeable from front and side perspectives. The lift fan itself abbreviates the aft end of the canopy line as well.
Panel lines and markings are associated with the lift system are visible on the top and bottom sides of the F-35B. From above, panel lines for the lift fan door and the auxiliary air inlet are visible. From below, the doors for lift fan exhaust appear just behind the front landing gear doors. The aft end of the lower fuselage also has a seam for the doors that open when the three-bearing swivel duct goes into action in STOVL mode. (The A and C models have a hump in this location where their arresting/barricade tailhooks are stored.) The B model also has a diamond-shaped roll duct on the underside of each wing.
The C model is most easily distinguished from other F-35 models by its larger wing, which provides almost fifty percent more wing area than the A and B models. The hinge line for the wing fold is visible from top and bottom views. The F-35C wing has an additional control surfaces, called ailerons, on the trailing edge as well (two control surfaces on each wing instead of one). The inner control surfaces on the F-35C wing and the ones on the A and B are called flaperons. The landing gear on the F-35C is noticeable beefier. The nose gear has two tires and a launch bar that extends forward and upward from the wheels.
Another Trick: Markings
Markings can also be used to distinguish F-35 variants. US Air Force markings equate to the A model. US Marines to the B or C model. (The Marine Corps is purchasing eighty C models.) And US Navy to the C model only. The Air Force puts the aircraft identification number, or serial number, on the tail (F-35A). The US Marines and Navy put their identification numbers, called Bureau numbers, on the empennage just below the horizontal tails. To make identification somewhat easier, the F-35 variant designation appears just above the bureau number for the US Marine Corps and Navy. Unfortunately, because of their location these markings are not apparent in most photos. International operators have their own specific requirements for markings.
Other Notes
As noted in a previous Code One article, Norwegian F-35s will be distinguishable by a small, aerodynamically clean bump on the upper fuselage between the two vertical tails. The bump contains a dragchute.
Nosebooms are peculiar to flight test F-35s dedicated to flight sciences testing.
The major differences between the X-35 demonstrator aircraft, which are no longer flying, and F-35 were covered in another previous Code One article.
Basic Cheat Sheet
The F-35A has a small wing, full canopy, gun blister on the left upper side, and aerial refueling receptacle markings on its dorsal. It has no panel lines or markings associated with a STOVL lift system.
The F-35B has a small wing, distinctive fuselage hump and abbreviated canopy (thanks to the lift fan), refueling probe on the right side, and numerous markings, panel lines, and actual hardware associated with its vertical lift system.
The F-35C has the big wing, wing folds, ailerons, full canopy, refueling probe on the right side, and a launch bar and two tires on the front landing gear. If the aircraft has Navy markings, it’s an F-35C.
This would be so much better if it was in focus! Forty four years ago today, 23 April 1981, RM 1577 is passing St. Paul`s Cathedral and could well be on its first day back on the road following overhaul given the spotless condition of it. But is it working from Riverside or Dalston Garage? Had the running number been clearer we would know but if it was Dalston it would only be there for a few days prior to the new Ash Grove Garage opening two days after this picture was taken.
It`s a bus with a history of being on the 11`s given that two radio aerials can be seen to the rear of the roof which confirms the route control system used on the 11`s known as CARLA (computer and radio location aid). Prior to overhaul this bus had the identity of RM 1865 and that would have been based at either Riverside or Dalston.

The North American F-86 Sabre (sometimes called the Sabrejet) was a transonic jet fighter aircraft. Produced by North American Aviation, the Sabre is best known as the United States's first swept wing fighter which could counter the similarly-winged Soviet MiG-15 in high-speed dogfights over the skies of the Korean War. Considered one of the best and most important fighter aircraft in the Korean War, the F-86 is also rated highly in comparison with fighters of other eras. Although it was developed in the late 1940s and was outdated by the end of the 1950s, the Sabre proved versatile and adaptable, and continued as a front-line fighter in numerous air forces until the last active operational examples were retired by the Bolivian Air Force in 1994.
Its success led to an extended production run of more than 7,800 aircraft between 1949 and 1956, in the United States, Japan and Italy. Variants were built in Canada and Australia. The Canadair Sabre added another 1,815 airframes, and the significantly redesigned CAC Sabre (sometimes known as the Avon Sabre or CAC CA-27), had a production run of 112. The Sabre was by far the most-produced Western jet fighter, with total production of all variants at 9,860 units.
NATO version of F-86D; MG-4 fire control system; four 20 mm M24A1 cannon with 132 rounds per gun; APG-37 radar. 120 were built by NAA, 221 were assembled by Fiat.

A college student in Hanoi, Vietnam, has spent up to $23,000 building his own Batmobile.
Nguyen Dac Chung, born in 1998, is a student of architecture and modelled his functional DIY project of the iconic supercar in the Batman film, "The Dark Knight."
Dac Chung said: “This product is a project that I have been cherishing for three years, and I have been working on it for more than 10 months."
Cool footage from September 5 shows the intricate design of the Batmobile that measures a nifty 3.6 metres long and 2.3 metres wide.
Dac Chung designed the car in 3D before building it himself. He ordered the tyres and wheels from America and South Korea and installed a full range of vehicle control systems, brakes, and lighting. Currently, Dac Chung is in the process of finishing the interior.
During the initial testing of the Arrow, there were no major problems but a few minor issues with the flight control system and the long landing gear began to emerge. The landing gear issue was predominantly with the tandem main gear. Since it was so narrow (in order to fit within the wings), the leg shortened and rotated as it was stowed. During one landing incident, the chain mechanism used to shorten the gear in the Mk. 1 gear jammed, resulting in incomplete rotation. In a second incident with RL-202 on 11 November 1958, the flight control system commanded elevons full down at landing, which put less weight on the landing gear, thus reducing tire friction, and resulting in brake lockup and subsequent gear collapse.
In this image, Arrow RL-202 experiences the infamous November landing gear collapse. The original photograph shows the brakes spewing flames and sparks, something I wanted to create for this image. I used a combination of Studio 2.0’s illumination rendering and some Photoshop trickery. I replaced the opaque runway tiles with illuminated tiles under the wheels, thus providing the glow on the underside of the model. I also “sunk” the back tires into the runway to make it look like they are flat. Unlike LDD, Studio 2.0 allows for overlapping or colliding pieces to be rendered so I took advantage of it for this image. The smoke and sparks were added in Photoshop, as well as all of the usual livery and effects.
AKSM-32100D is a trolleybus with a transistorized control system based on IGBT modules and an AC induction motor, equipped with accumulators based on lithium-iron-phosphate batteries with a reserve of autonomous travel up to 30 kilometers. Unlike base model AKSM-32100, it is equipped with a 150 kW traction motor. The first three ones were delivered to Ulyanovsk, Russia at the end of 2015. In 2016-2019 St. Petersburg received 35 ones, others were delivered to Belarus cities (5 to Grodno, 4 to Gomel, 4 to Vitebsk). In 2021, they were delivered to Belarus capital Minsk (25 ones) and Vratsa (9). In December 2021, three more restyled trolleybuses came to Grodno to operate the new route 24.
АКСМ-32100D trolleybuses are produced by the Belarus company Belkommunmash (BKM; Производственное Объединение «Белкоммунмаш», БКМ). BKM was organized in 1973 on the basis of the streetcar and trolleybus repair shop under the Ministry of Municipal Economy of the Belarusian Soviet Socialist Republic. During the first two decades the plant was repairing trolleybuses and streetcars of Minsk. After USSR breakage the independent Belarus got a strong incentive to develop its own vehicles production. Therefore a few articulated trolleybuses YMZ T1 (ЮМЗ Т1) were assembled at the plant in 1993 from engineering sets of Yuzhny Machine Building Plant of Ukraine. The enterprise also modernized trolleybuses of the ZIU models 100 - 101 produced by the Engels Electric Transportation Plant (later CJSC "TrolZa") in Engels, Saratov region of Russia. Later the company started to develop its own trolleybus models, the first model AKSM 201 (АКСМ 201) appeared in 1996, followed by models 213, 221, 321 (as in foto) and 333. Since 2000 the production of streetcars started: AKSM-1M, AKSM-60102. In 2016, the production of electric buses has been organized. Today the BKM Holding (ОАО «Управляющая компания холдинга «Белкоммунмаш» - ОАО «УКХ «БКМ) is the leading industrial enterprise in Belarus in the field of production and overhaul of rolling stock of urban electric transport.
Had the pleasure of watching "DOC" fly into New Century Air Center yesterday for an airshow. No crowd! Very fortunate.
In late 1939, the Army Air Corps issued a formal specification for a "superbomber", capable of delivering 20,000 lbs of bombs to a target 2,600 miles away at 400 mph.
The B-29 Superfortress was one of the most advanced bombers of the time, with innovations such as a pressurized cabin, a central fire-control system, and remote-controlled machine gun turrets.
In wartime, the B-29 was capable of flight up to 31,850 feet at speeds of 350 mph. Designed as a high-altitude daytime bomber, the B-29 flew more low-altitude nighttime incendiary bombing missions.
As part of the World War II military buildup, 3,970 B-29s were built during production at four assembly plants across the United States.
Doc is a B-29 Superfortress and one of 1,644 manufactured in Wichita during World War II. Since 1987 when Tony Mazzolini found Doc on sitting and rotting away in the Mojave Desert, plans have been in the works to restore the historic warbird to flying status to serve as a flying museum.
Over the past 15+ years, hundreds of volunteers have worked on Doc and the restoration project. Skilled workers and retirees from Wichita’s aviation industry, veterans, active duty military and others wanting to honor those who served, have spent tens of thousands of hours on Doc’s restoration. Countless individuals and organizations also made financial and in-kind contributions to keep the project going. Below is a brief timeline of Doc’s military service, the restoration effort and Doc’s current mission.
In March of 1945, B-29 No. 44-69972 (now known as Doc) was delivered to the U.S. Army. About five months later another B-29 was used to drop two atomic bombs on Japan, eventually leading to Japan’s surrender and the end of World War II.
In July of 1951, Doc was assigned to radar calibration duty, along with a few other B-29s. The squadron was known as the Seven Dwarfs. In May of 1955, Doc was assigned to target-towing duty and in March a year later, Doc and the rest of its squadron became targets for bomb training at China Lake, California.
For 42 years, Doc sat in the Mojave Desert serving as a target for the U.S. Navy. In 1987, Tony Mazzolini found Doc and began plans to remove and eventually restore the B-29 warbird to flying status. It would take another 12 years before Mazzolini and his team would be able to take possession of the airplane from the U.S. government.
After more than a decade of contacting multiple government agencies and working with volunteers in the China Lake area, Tony took possession of the once target practice plane. A few months later in April of 1998, Tony and his team of volunteers towed Doc out of its 42 year resting place on the floor of the Mojave Desert.
After arranging for an inspection by an expert on aging Boeing aircraft, Mazzolini realized it would take extensive resources and specific expertise to return the Doc to flying condition. So the B-29 returned to Wichita in sections on flatbed trailers in May of 2000. Volunteers began the process of reassembling the B-29 and drew up plans to restore the historic warbird which was now sitting a few hundred feet from where it first rolled off the Boeing-Wichita assembly line some 50+ years before. Dedicated volunteers spent countless hours in the early stages of restoring the historic plane.
In February of 2013, a group of Wichita aviation enthusiasts & business leaders led by retired Spirit AeroSystems CEO Jeff Turner formed Doc’s Friends, a 501c3 non-profit board to manage the restoration project and help see it through to completion.
Doc's first flight after the restoration process was 2016.

“A future “space taxi” capable of transporting “passengers other than trained astronauts” to earth orbital stations “or to any point on earth within 45 minutes” was described to 150 international scientists meeting in Palo Alto today.
The single-stage, multi-purpose rocket launch vehicle would be “recoverable and reusable,” Douglas Aircraft Company engineer Phil Bono said.
The week-long event is sponsored by the Society of Automotive Engineers (SAE).
He told the space scientists from Britain, France, Germany and Italy that by refueling in earth orbit, the Douglas designed satellite could also land passengers and cargo on the moon.
SPACE FIGHTER
Bono said the giant rocket could also have military applications including “the jet fighter of the space age…”
Unfortunately, the rest of the article was omitted when affixed to the verso.
8.5” x 11”, so likely original Douglas Aircraft Company-produced for professional presentation, and in this case, press purposes, hence it not being appropriately handled. Fortunately, and despite such, it’s still retained its gloss.
Gorgeous airbrush work by either "Pisakov" or "P. Isakov"...unfortunately, either way...nothing on him/her. Drats.
Also, from the excellent “ATOMIC ROCKETS” website:
“The Saturn Application Single-Stage-to-Orbit (SASSTO) is from Frontiers of Space by Philip Bono and Kenneth Gatland (1969).
In 1966, when winged space shuttle designs were being studied, the Douglas Aircraft Company was doing a cost-benefit analysis. They were comparing reusable space shuttle costs to throwaway two-stage ballistic boosters. Somewhere along the line they took a look at whether it was possible to make a reusable single stage ballistic booster. The SASSTO was the result. The payload was not much, but it was enough for a Gemini space capsule. A Gemini would transform the SASSTO into a space taxi or even a space fighter, capable of satellite inspection missions. Without the Gemini it could deliver supplies and propellant to space stations and spacecraft in LEO.
Bono pointed out how inoperative satellites could become space hazards (although the concept of the Kessler Syndrome would not be created until 1978). A SASSTO could deal with such satellites in LEO (Bono called this Saturn Application Retrieval and Rescue Apparatus or SARRA). Even better, such satellites could be grabbed and brought back to Terra for refurbishment and re-launch. This would be much cheaper than building an entirely new satellite from scratch, which would interest satellite corporations. Only satellites in LEO though, communication satellites in geostationary orbit would be out of reach.
The interesting part was on the base. Conventional spacecraft trying to do an aerobraking landing need a large convex heat shield on the base (for example the Apollo command module.). Unfortunately, a reusable spacecraft has a large concave exhaust nozzle on the bottom, exactly the opposite of what you want. Tinsley's artist conception for the "Mars Snooper" had petals that would close over the exhaust nozzle sticking out of the heat shield, but that was impractical.
Douglas' solution was to use an aerospike engine with the spike truncated (which they confusingly call a "plug nozzle", contrary to modern terminology). The truncated part became the heat shield, the untruncated part around the edge was the aerospike engine.”

Additionally, and more directly, from the equally excellent SECRET PROJECTS Forum website, posted by Donald McKelvy/user “Triton” on 24 August 2009, apparently taken from Mr. Bono’s document/presentation at the above referenced SAE Conference Proceedings:
“In late 1966, the vertical launch & landing SSTO proponents at Douglas Aircraft Co. carried out a study to determine whether ballistic VTVLs might be cost-competitive vs. winged VTHL TSTO vehicles in the small payload class. Previous NASA & USAF studies had generally assumed ballistic single-stage vehicles might make sense for unmanned heavy-lift payloads but winged TSTOs were invariably chosen for small manned near-term missions. Consequently, Douglas had to define a small VTVL SSTO manned "space taxi" to demonstrate the key elements of the concept (aerospike engine, lightweight structures, ballistic reentry, vertical landing, actively cooled heatshield etc.) The resulting vehicle became known as "Saturn Application Single Stage to Orbit". Notable design features included an aft-mounted liquid oxygen tank to reduce the difference between vehicle center of gravity & center of aerodynamic pressure, and a hydrogen cooling system for the main engine to provide thermal protection during reentry. Thermal analysis indicated that although the engine itself would be adequately protected by this system, the areas located above the exhaust nozzles would not. Consequently, the designers had to resort to an ablative, expendable material (200 kilograms of Armstrong Insulcork 2760) bonded to the aluminum structure although it would increase the maintenance cost. The oxygen/hydrogen mixture ratio was 6:1 rather than 7:1 since the designers felt a high oxygen ratio would degrade the exhaust velocity & payload capability. 50% hydrogen slush was used to reduce the volume of the fuel tank. The 36-segment plug nozzle propulsion system would have operated at a pressure of 1500psia. It would be used for ascent, orbit insertion, de-orbit and (beginning at an altitude of 760 meters-) the final landing burn. The vehicle would carry enough propellant for hovering for 10 seconds before landing at an unprepared site, if necessary. The estimated landing accuracy of 1853 * 3700 m was not regarded as a major concern since the Gemini 6-12 flights achieved an average touchdown dispersion of only 6.85km although the capsule had essentially no maneuvering capability below 30.5km altitude. The reentry cross-range capability was about +/-370km, permitting a safe landing at El Paso, TX or Wendover Range, UT after 2-3 orbits from Cape Canaveral. Wendover was the preferred emergency landing site since SASSTO easily could have been returned from nearby Hill AFB to Cape Canaveral in a "Pregnant Guppy" S-IV-B transport aircraft.
SASSTO had a payload capability of 3,629kg to a 185km orbit and the standard payload would be a 2-man Gemini spacecraft protected by a jettisonable fairing to reduce drag losses during ascent. This would provide a safe emergency escape system for the test pilots, and the Gemini ejection seats, heatshield, parachutes etc. (1542kg in all) could later be removed as the flight test program increases confidence in SASSTO reliability. Douglas envisioned this vehicle as a "space fighter" capable of satellite inspection missions, or space station resupply flights lasting a maximum of 48 hours. It could also deliver 2,812kg of liquid hydrogen to a spacecraft in Earth orbit.
Since SASSTO was loosely based on the Saturn S-IV-B rocket stage, Douglas also proposed an expendable version for use as a more capable upper stage with the Saturn IB and Saturn V launch vehicles. The expendable SASSTO stage would have had a burnout mass of 7,400kg and carried 85,729kg of oxygen + hydrogen propellant. The stage was thus of a much more lightweight construction than the standard S-IV-B (12,949kg + 104,326kg LOX, LH₂) and the new aerospike engine would have been more efficient as well (464s specific impulse vs. 426s for the J-2 engine). Consequently, the Saturn V's payload capability would have been boosted by 8-11t as well. The Saturn IB's basic 15876-kilogram payload capability to a 185km orbit would have increased to 23814-25855kg depending on whether SASSTO would be flown in expendable or reusable mode. The latter version was known as SARRA (Saturn Application Retrieval and Rescue Apparatus) and was intended for returning stranded Apollo crews from the lunar surface.
Finally, the Douglas design team also compared the cost of SASSTO with two different all-rocket VTHL TSTOs: a winged 1st stage plus lifting-body 2nd stage (center) and winged first & second stages (right). All three vehicles were designed for a 2,812-kilogram payload although the lifting-body TSTO only was able to carry 2,086kg due to center of gravity problems. No attempt was made to estimate the marginal launch cost since there were too many unknown factors. VTVL SSTO would however be expected to yield a significant operational advantage since only a single vehicle must be maintained and the VTVL SSTO does not require a landing runway. SASSTO was expected to cost $1.1. billion to develop (=$5.88B at 1999 rates). The winged VTHL TSTO would cost 2.2 times as much to develop as SASSTO while the smaller lifting-body TSTO variant would be 50% more expensive. The winged and lifting-body 1st unit production costs would be 4 and 2.7 times higher than the SASSTO 1st unit cost, respectively. The general conclusion was that the complex winged or lifting body TSTO shapes result in added liftoff and manufactured weights of a more expensive construction than ballistic wingless SSTOs. For example, the lifting-body TSTO dry mass (12,274kg + 2,086kg payload) is 2.4 times higher, and the winged TSTO weighs 3.6 times as much (18,176kg + 2,812kg P/L) as SASSTO at touchdown. The gross liftoff weights bear the relationships of 1.0 (SASSTO; 97,887kg GLOW), 1.25 (lifting body orbiter TSTO; 122,245kg GLOW) and 1.91 (wing-body orbiter TSTO; 187,020kg GLOW). In that case, is the combination of lower reentry g-loads, better maneuverability (landing go-around with jet engines) and improved cross-range really worth the cost of carrying wings...? Although TSTO thus appears to be uncompetitive vs. ballistic single-stage RLVs for small payloads, the authors admit that requirements for higher payloads (22.68-45.6t) may yield rapid increases in propellant mass fraction for winged two-stage vehicles, making TSTO more performance/cost-effective.

Finally...possibly the best write-up of Mr. Bono's career that I’ve come across:
"Philip Bono was a renowned space engineer who was probably 30 years before his time. He was born in Brooklyn, New York on January 13, 1921. He graduated from the University of Southern California in 1947 with a B.E. degree in mechanical engineering, and served three years in the U.S. Naval Reserves.
After graduation in 1947, Mr. Bono worked as a research and systems analyst for North American Aviation. His first "tour" with Douglas Aircraft Company was from 1949 to 1951, doing structural layout and detail design. From 1951 to 1960, he worked primarily in structures design at Boeing. Between 1947 and 1949, he worked at Northrop Aircraft R&D. From 1984-1986, he was general manager of Cal-Pro Engineering Consultants doing structures integration and subsystems stress analysis. From 1966 to 1988, he again worked at Douglas Aircraft after Douglas' merger with McDonnell Aircraft where he did the majority of his advanced space design work. He pursued single-stage to orbit space launch vehicles as being simpler and cheaper than conventional launch vehicles. He then proposed to make these vehicles reusable.
Among Mr. Bono's designs were: One Stage Orbital Space Truck (OOST) Recoverable One Stage Orbital Space Truck (ROOST) Reusable Orbital Module, Booster, and Utility Shuttle (ROMBUS), Ithacus, Pegasus, Hyperion, and Saturn Application Single Stage To Orbit (SASSTO). Although his visionary designs were never actually built, his contributions pioneered the advancement of the Space Shuttle, a vertical take off & horizontal landing version of the SSTO spacecraft. From his ROOST design onwards, Bono advocated space launch vehicles without wings, usually using rocket-assisted vertical takeoff and landing (VTVL) configurations. He patented a reusable plug nozzle rocket engine that had dual use as a heat shield for atmospheric reentry. In 1965 and 1967, he obtained two patents for a Recoverable Single Stage Spacecraft Booster. In 1969, he co-authored with Kenneth Gatland "Frontiers of Space," which was published in several languages. Less than three months after Bono's death, the first McDonnell Douglas launch vehicle based on his pioneering work on VTOL, a research test vehicle the DC-X (Delta Clipper), began a largely successful series of test flights.
Among his many awards and recognitions, the Council on International Nontheatrical Events recognized Mr. Bono for his motion picture, "The Role of the Reusable Booster." His ROMBUS design was featured in the "Flight to the Moon" attraction at Disneyland in Anaheim, California in 1967. He was granted Charter Membership in the International Astronautical Academy in 1960, and acknowledgment by the American Institute of Aeronautics and Astronautics in 1963, 1965, and 1966 through 1968. He achieved Fellowship in The British Interplanetary Society in 1961, and was elected a Fellow of the Royal Aeronautical Society in 1972. His wife of 43 years, Camille, died in November 2014. His son Richard and daughter Patricia, both live in Costa Mesa, California, and daughter Kathryn Hickman lives in Livermore, California. Philip Bono died on May 23, 1993 at the age of 72 in Costa Mesa, California."

“STS-30 --- The Space Shuttle Atlantis glides toward a landing on the Mojave Desert after spending just over four full days in space. Aboard the spacecraft were Astronauts David M. Walker, Ronald J. Crabe, Norman E. Thagard, Mary L. Cleave and Mark C. Lee. Moments later, the spacecraft’s landing gear came to a stop at 12:44:33 p.m. (PDT), 8 May 19890. It landed on Runway 22, a concrete facility, like a number of other NASA flights. Still others have landed on unpaved dry lake bed strips.”
Not a mention of the mission, the deployment of the Magellan/Venus radar mapper spacecraft - THE FIRST U.S. PLANETARY MISSION IN ELEVEN - 11 - IIIII IIIII I years! But by golly, now we know that, like a number of other orbiters, it landed on a concrete runway! The pièce de résistance: 'still others' landed on unpaved dry lake beds!!! No!?! Really?!? That being the key takeaway from this photograph. O - M - G. The bar being exceedingly low, at least it didn’t reference the pretty clouds in the bright blue sky.

The 2400 class was a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways in 1977/78.
The 2400 class were an evolution of the 1550 class. They differed in having the modular control system incorporated into the electrical cabinet. Originally it was intended to continue their number sequence from the last 1550, i.e. the first would have been 1577, but this would have required the 1600 class to have been renumbered, so they were instead numbered as the 2400 class.[1][2][3]
Between 1999 and 2002, eighteen were rebuilt as 2300 class locomotives at Redbank Railway Workshops.[4][5] The remaining six were withdrawn[6] with one exported in August 2013 to South Africa.[7]
