A flying wing is a tailless fixed-wing aircraft that has no definite fuselage, with its crew, payload, fuel, and equipment housed inside the main wing structure. A flying wing may have various small protuberances such as pods, nacelles, blisters, booms, or vertical stabilizers.
Similar aircraft designs, that are not technically flying wings, are sometimes casually referred to as such. These types include blended wing body aircraft and lifting body aircraft, which have a fuselage and no definite wings.
A pure flying wing is theoretically the lowest drag design configuration for a fixed wing aircraft. However, because it lacks conventional stabilizing surfaces and the associated control surfaces, in its purest form the flying wing suffers from being unstable and difficult to control.
The basic flying wing configuration became an object of significant study during the 1920s, often in conjunction with other tailless designs. In the Second World War, both Nazi Germany and the Allies made advances in developing flying wings. Military interest in the flying wing waned during the 1950s with the development of supersonic aircraft, but was renewed in the 1980s due to their potential for stealth technology. This approach eventually led to the Northrop Grumman B-2 Spirit stealth bomber. There has been continual interest in using it in the large transport roles for cargo or passengers. Boeing, McDonnell Douglas, and Armstrong Whitworth have undertaken design studies on flying wing airliners; however, no such airliners have yet been built.
The flying wing concept is mostly suited to subsonic aircraft. No supersonic flying wing has ever been built.

VANDENBERG AIR FORCE BASE, Calif. – In the mobile service tower at Space Launch Complex 2 at Vandenberg Air Force Base in California, technicians are inspecting the NASA's Orbiting Carbon Observatory-2, or OCO-2, satellite. The task is taking place prior to encapsulation in its payload fairing atop a United Launch Alliance Delta II rocket. Launch is scheduled for 2:56 a.m. PDT 5:56 a.m. EDT on July 1. OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural "sinks" that absorb carbon dioxide and help control its buildup. The observatory will measure the global geographic distribution of these sources and sinks and study their changes over time.

A C-5 air cargo plane opens to reveal a shipping container with payload flight hardware for the Third Hubble Space Telescope Servicing Mission (SM-3A). The hardware will be taken to the Payload Hazardous Servicing Facility for final testing and integration of payload elements. Mission STS-103 is a "call-up" mission which is being planned due to the need to replace portions of the Hubble's pointing system, the gyros, which have begun to fail. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will not only replace gyroscopes, it will also replace a Fine Guidance Sensor and an older computer with a new enhanced model, an older data tape recorder with a solid state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Launch of STS-93 is currently targeted for Oct. 14 but under review, pending the launch date of a prior mission, STS-99, also under review.

Discovery STO - 70 Ton, Single Stage to Orbit Fixed Wing Aircraft - Space Plane - Hypersonic Plane, U-TBCC / Unified Turbine Based Combined Cycle & Aerospike
Iteration 1, Mach 8-10 in amtmosphere, 195ft long, Heavy Lift Single Stage To Orbit Fixed Wing Aircraft. 70 TONS, ie 140,000 LBS, 60 ft X 15ft X 15ft payload bay. Up in the Falcon Heavy and Delta IV class, except not $400 million to launch giant payloads into orbit, but below $250 per lbs, or about $28 million to launch giant payloads, and normalized orbital flight, as normal as a 737 commercial flight. Load up, refuel, take off in an afternoon. I estimate this aircraft would cost about $750 million each for space capable. In atmosphere commercial, roughly $300 million each for a 200 passenger M8-10 (not designed yet)

Unified Turbine Based Combined Cycle. Current technologies and what Lockheed is trying to force on the Dept of Defense, for that low speed Mach 5 plane DOD gave them $1 billion to build and would disintegrate above Mach 5, is TBCC. 2 separate propulsion systems in the same airframe, which requires TWICE the airframe space to use.
Unified Turbine Based Combined Cycle is 1 propulsion system cutting that airframe deficit in half, and also able to operate above Mach 10 up to Mach 15 in atmosphere, and a simple nozzle modification allows for outside atmosphere rocket mode, ie orbital capable.
Additionally, Reaction Engines maximum air breather mode is Mach 4.5, above that it will explode in flight from internal pressures are too high to operate. Thus, must switch to non air breather rocket mode to operate in atmosphere in hypersonic velocities. Which as a result, makes it not feasible for anything practical. It also takes an immense amount of fuel to function.

Advanced Additive Manufacturing for Hypersonic Aircraft
Utilizing new methods of fabrication and construction, make it possible to use additive manufacturing, dramatically reducing the time and costs of producing hypersonic platforms from missiles, aircraft, and space capable craft. Instead of aircraft being produced in piece, then bolted together; small platforms can be produced as a single unit and large platforms can be produces in large section and mated without bolting. These techniques include using exotic materials and advanced assembly processes, with an end result of streamlining the production costs and time for hypersonic aircraft; reducing months of assembly to weeks. Overall, this process greatly reduced the cost for producing hypersonic platforms. Even to such an extent that a Hellfire missile costs apx $100,000 but by utilizing our technologies, replacing it with a Mach 8-10 hypersonic missile of our physics/engineering and that missile would cost roughly $75,000 each delivered.
Materials used for these manufacturing processes are not disclosed, but overall, provides a foundation for extremely high stresses and thermodynamics, ideal for hypersonic platforms. This specific methodology and materials applications is many decades ahead of all known programs. Even to the extend of normalized space flight and re-entry, without concern of thermodynamic failure.
*Note, most entities that are experimenting with additive manufacturing for hypersonic aircraft, this makes it mainstream and standardized processes, which also applies for mass production.
What would normally be measured in years and perhaps a decade to go from drawing board to test flights, is reduced to singular months and ready for production within a year maximum.
Unified Turbine Based Combined Cycle (U-TBCC)
To date, the closest that NASA and industry have achieved for turbine based aircraft to fly at hypersonic velocities is by mounting a turbine into an aircraft and sharing the inlet with a scramjet or rocket based motor. Reaction Engines Sabre is not able to achieve hypersonic velocities and can only transition into a non air breathing rocket for beyond Mach 4.5
However, utilizing Unified Turbine Based Combine Cycle also known as U-TBCC, the two separate platforms are able to share a common inlet and the dual mode ramjet/scramjet is contained within the engine itself, which allows for a much smaller airframe footprint, thus engingeers are able to then design much higher performance aerial platforms for hypersonic flight, including the ability for constructing true single stage to orbit aircraft by utilizing a modification/version that allows for transition to outside atmosphere propulsion without any other propulsion platforms within the aircraft. By transitioning and developing aircraft to use Unified Turbine Based Combined Cycle, this propulsion system opens up new options to replace that airframe deficit for increased fuel capacity and/or payload.
Enhanced Dynamic Cavitation
Dramatically Increasing the efficiency of fuel air mixture for combustion processes at hypersonic velocities within scramjet propulsion platforms. The aspects of these processes are non disclosable.
Dynamic Scramjet Ignition Processes
For optimal scramjet ignition, a process known as Self Start is sought after, but in many cases if the platform becomes out of attitude, the scramjet will ignite. We have already solved this problem which as a result, a scramjet propulsion system can ignite at lower velocities, high velocities, at optimal attitude or not optimal attitude. It doesn't matter, it will ignite anyways at the proper point for maximum thrust capabilities at hypersonic velocities.
Hydrogen vs Kerosene Fuel Sources
Kerosene is an easy fuel to work with, and most western nations developing scramjet platforms use Kerosene for that fact. However, while kerosene has better thermal properties then Hydrogen, Hydrogen is a far superior fuel source in scramjet propulsion flight, do it having a much higher efficiency capability. Because of this aspect, in conjunction with our developments, it allows for a MUCH increased fuel to air mixture, combustion, thrust; and ability for higher speeds; instead of very low hypersonic velocities in the Mach 5-6 range. Instead, Mach 8-10 range, while we have begun developing hypersonic capabilities to exceed 15 in atmosphere within less then 5 years.
Conforming High Pressure Tank Technology for CNG and H2.
As most know in hypersonics, Hydrogen is a superior fuel source, but due to the storage abilities, can only be stored in cylinders thus much less fuel supply. Not anymore, we developed conforming high pressure storage technology for use in aerospace, automotive sectors, maritime, etc; which means any overall shape required for 8,000+ PSI CNG or Hydrogen. For hypersonic platforms, this means the ability to store a much larger volume of hydrogen vs cylinders.
As an example, X-43 flown by Nasa which flew at Mach 9.97. The fuel source was Hydrogen, which is extremely more volatile and combustible then kerosene (JP-7), via a cylinder in the main body. If it had used our technology, that entire section of the airframe would had been an 8,000 PSI H2 tank, which would had yielded 5-6 times the capacity. While the X-43 flew 11 seconds under power at Mach 9.97, at 6 times the fuel capacity would had yielded apx 66 seconds of fuel under power at Mach 9.97. If it had flew slower, around Mach 6, same principles applied would had yielded apx 500 seconds of fuel supply under power (slower speeds required less energy to maintain).
Enhanced Fuel Mixture During Shock Train Interaction
Normally, fuel injection is conducted at the correct insertion point within the shock train for maximum burn/combustion. Our methodologies differ, since almost half the fuel injection is conducted PRE shock train within the isolator, so at the point of isolator injection the fuel enhances the combustion process, which then requires less fuel injection to reach the same level of thrust capabilities.
Improved Bow Shock Interaction
Smoother interaction at hypersonic velocities and mitigating heat/stresses for beyond Mach 6 thermodynamics, which extraordinarily improves Type 3, 4, and 5 shock interaction.
6,000+ Fahrenheit Thermal Resistance
To date, the maximum thermal resistance was tested at AFRL in the spring of 2018, which resulted in a 3,200F thermal resistance for a short duration. This technology, allows for normalized hypersonic thermal resistance of 3,000-3,500F sustained, and up to 6,500F resistance for short endurance, ie 90 seconds or less. 10-20 minute resistance estimate approximately 4,500F +/- 200F.
*** This technology advancement also applies to Aerospike rocket engines, in which it is common for Aerospike's to exceed 4,500-5,000F temperatures, which results in the melting of the reversed bell housing. That melting no longer ocurrs, providing for stable combustion to ocurr for the entire flight envelope
Scramjet Propulsion Side Wall Cooling
With old technologies, side wall cooling is required for hypersonic flight and scramjet propulsion systems, otherwise the isolator and combustion regions of a scramjet would melt, even using advanced ablatives and ceramics, due to their inability to cope with very high temperatures. Using technology we have developed for very high thermodynamics and high stresses, side wall cooling is no longer required, thus removing that variable from the design process and focusing on improved ignition processes and increasing net thrust values.
Lower Threshold for Hypersonic Ignition
Active and adaptive flight dynamics, resulting in the ability for scramjet ignition at a much lower velocity, ie within ramjet envelope, between Mach 2-4, and seamless transition from supersonic to hypersonic flight, ie supersonic ramjet (scramjet). This active and dynamic aspect, has a wide variety of parameters for many flight dynamics, velocities, and altitudes; which means platforms no longer need to be engineered for specific altitude ranges or preset velocities, but those parameters can then be selected during launch configuration and are able to adapt actively in flight.
Dramatically Improved Maneuvering Capabilities at Hypersonic Velocities
Hypersonic vehicles, like their less technologically advanced brethren, use large actuator and the developers hope those controls surfaces do not disintegrate in flight. In reality, it is like rolling the dice, they may or may not survive, hence another reason why the attempt to keep velocities to Mach 6 or below. We have shrunken down control actuators while almost doubling torque and response capabilities specifically for hypersonic dynamics and extreme stresses involved, which makes it possible for maximum input authority for Mach 10 and beyond.
Paradigm Shift in Control Surface Methodologies, Increasing Control Authority (Internal Mechanical Applications)
To date, most control surfaces for hypersonic missile platforms still use fins, similar to lower speed conventional missiles, and some using ducted fins. This is mostly due to lack of comprehension of hypersonic velocities in their own favor. Instead, the body itself incorporates those control surfaces, greatly enhancing the airframe strength, opening up more space for hardware and fuel capacity; while simultaneously enhancing the platforms maneuvering capabilities.
A scramjet missile can then fly like conventional missile platforms, and not straight and level at high altitudes, losing velocity on it's decent trajectory to target. Another added benefit to this aspect, is the ability to extend range greatly, so if anyone elses hypersonic missile platform were developed for 400 mile range, falling out of the sky due to lack of glide capabilities; our platforms can easily reach 600+ miles, with minimal glide deceleration.

Though the A-4 Skyhawk was by no means outdated by 1962, the US Navy began work on a replacement with better range and heavier payload. The designs submitted would be necessarily heavier than the A-4, but this was not seen as much of a problem, nor was a lack of speed: the Navy was willing to trade subsonic performance for increased range and more bombs. Ling-Temco-Vought (LTV) submitted a design based loosely on its successful F-8 Crusader fighter, which was enough to beat out three other designs, and it was ordered into production as the A-7A Corsair II, named for the successful Chance-Vought fighter of World War II.
Though the A-7 was based on the F-8, the two shared very little other than basic configuration: the A-7 was stubby and wide, and definitely subsonic as intended, though it initially used the same powerplant as the F-111 Aardvark. Turn performance was excellent, if acceleration was indifferent, but the centerpiece of the Corsair II was its integrated bomb delivery system. This included the APQ-116 radar, a heads-up display, traveling map display below the radarscope, and a digital computer. Ease of maintenance was also emphasized. With no problems encountered in flight testing, the A-7A entered fleet service in 1967.
It was immediately committed to fighting in Vietnam. Though A-7s would only see action in the tail end of Operation Rolling Thunder, they were to be used extensively in South Vietnam, due to their accuracy: A-7s were capable of putting ordnance within sixty feet of friendly troops, making it well-liked. The Navy liked the USAF's A-7D variant, and subsequently adopted it, with changes for naval operations, as the A-7E. This was to be the definitive model of the Corsair II, and surviving A-7As and A-7Bs were converted to E standard.
It was a mixed batch of A-7 models that finished the war in Vietnam: A-7Bs were mostly used in the suppression of enemy air defenses (SEAD) Wild Weasel role, and increasingly Corsair IIs were armed with precision weapons such as the AGM-62 Walleye, which proved capable enough to destroy the infamous Thanh Hoa Bridge—albeit temporarily—in 1972. The workhorse A-7 also struck targets in the Hanoi area extensively, making it second only to the B-52 in amount of ordnance dropped on the North Vietnamese capital. Navy A-7s from USS Coral Sea participated in the last combat missions of the Vietnam War, the Mayaguez rescue mission in May 1975. 98 Navy A-7s were shot down during the conflict.
Following the end of the Vietnam War, the A-7 replaced the A-4 in Navy light attack squadrons, standardizing on the A-7E. Aside from minor upgrades, this would remain the type used by Navy units for the duration of the Corsair II’s career. A-7s would go on to participate in every military operation undertaken by the United States in the 1980s—attacks on Lebanon and the invasion of Grenada in 1983, operations against Libya in 1985, during the “Tanker War” in the Persian Gulf in 1987, and finally in the First Gulf War in 1991. In these operations, the A-7 was able to use its pinpoint bombing ability to good use; in Libya and the Persian Gulf, Corsair IIs attacked and sank numerous Libyan and Iranian patrol boats with unguided bombs. It also was the Navy’s Wild Weasel of choice during the 1980s, using the Vietnam-era Shrike before upgrading to the far superior HARM.
In Operation Desert Storm, two A-7 squadrons from John F. Kennedy were used both to attack fixed targets with “iron” bombs and Walleyes in “tank plinking”—knocking out Iraqi tanks with precision weapons. Despite there being less than 30 A-7s in theater, these aircraft were able supplements to the USAF’s A-10s and F-111s.
The First Gulf War was the A-7’s swan song. The last squadrons gave up their Corsair IIs for F/A-18 Hornets by May 1991, ending nearly thirty years of operations. Some ex-Navy A-7s were passed on to Greece, Portugal, and Thailand, and some still remain in service with Thailand and Greece. Of the 1569 A-7s built, about half were Navy types, and today 20 former US Navy A-7s are on display as gate guards and museum pieces.
A-7B BuNo 154554 began its career with VA-93 ("Blue Blazers") in 1969 aboard the USS Midway (CV-41), where it saw combat over Vietnam. In 1973, it was shifted to VA-56 ("Boomerangs"), remaining on the Midway. By 1983, it was with VA-305 ("Lobos"), a Naval Reserve unit at NAS Point Mugu, California, and retired from the squadron in 1986. It then became a ground instruction trainer for a few years, before being donated to the San Diego Air and Space Museum in 1994.
154554 has been mostly restored in the colors of VA-147 ("Argonauts") during the squadron's Vietnam deployment aboard the USS Ranger (CV-61), though this aircraft doesn't appear to have flown with VA-147. It is displayed with two Rockeye CBU cluster bombs under the wings and two AIM-9 Sidewinders on the fuselage rails. We saw it at the Gillespie Annex in May 2021.

VANDENBERG AFB, Calif. -- A Boeing Delta II rocket soars above the clouds here today at Vandenberg AFB, Calif. The NASA payloads aboard the rocket are the ICESat, an Ice Cloud and land Elevation Satellite, and CHIPSat, a Cosmic Hot Interstellar Plasma Spectrometer. ICESat, a 661-pound satellite, is a benchmark satellite for the Earth Observing System that will help scientists determine if the global sea level is rising or falling. It will observe the ice sheets that blanket the Earths poles to determine if they are growing or shrinking. It will assist in developing an understanding of how changes in the Earths atmosphere and climate affect polar ice masses and global sea level. The Geoscience Laser Altimeter System is the sole instrument on the satellite. CHIPSat, a suitcase-size 131-pound satellite, will provide information about the origin, physical processes and properties of the hot gas contained in the interstellar medium. This launch marks the first Delta from Vandenberg this year. (USAF photo by: SSgt.

Though the A-4 Skyhawk was by no means outdated by 1962, the US Navy began work on a replacement with better range and heavier payload. The designs submitted would be necessarily heavier than the A-4, but this was not seen as much of a problem, nor was a lack of speed: the Navy was willing to trade subsonic performance for increased range and more bombs. Ling-Temco-Vought (LTV) submitted a design based loosely on its successful F-8 Crusader fighter, which was enough to beat out three other designs, and it was ordered into production as the A-7A Corsair II, named for the successful Chance-Vought fighter of World War II.
Though the A-7 was based on the F-8, the two shared very little other than basic configuration: the A-7 was stubby and wide, and definitely subsonic as intended, though it initially used the same powerplant as the F-111 Aardvark. Turn performance was excellent, if acceleration was indifferent, but the centerpiece of the Corsair II was its integrated bomb delivery system. This included the APQ-116 radar, a heads-up display, traveling map display below the radarscope, and a digital computer. Ease of maintenance was also emphasized. With no problems encountered in flight testing, the A-7A entered fleet service in 1967.
It was immediately committed to fighting in Vietnam. Though A-7s would only see action in the tail end of Operation Rolling Thunder, they were to be used extensively in South Vietnam, due to their accuracy: A-7s were capable of putting ordnance within sixty feet of friendly troops, making it well-liked. The Navy liked the USAF's A-7D variant, and subsequently adopted it, with changes for naval operations, as the A-7E. This was to be the definitive model of the Corsair II, and surviving A-7As and A-7Bs were converted to E standard.
It was a mixed batch of A-7 models that finished the war in Vietnam: A-7Bs were mostly used in the suppression of enemy air defenses (SEAD) Wild Weasel role, and increasingly Corsair IIs were armed with precision weapons such as the AGM-62 Walleye, which proved capable enough to destroy the infamous Thanh Hoa Bridge—albeit temporarily—in 1972. The workhorse A-7 also struck targets in the Hanoi area extensively, making it second only to the B-52 in amount of ordnance dropped on the North Vietnamese capital. Navy A-7s from USS Coral Sea participated in the last combat missions of the Vietnam War, the Mayaguez rescue mission in May 1975. 98 Navy A-7s were shot down during the conflict.
Following the end of the Vietnam War, the A-7 replaced the A-4 in Navy light attack squadrons, standardizing on the A-7E. Aside from minor upgrades, this would remain the type used by Navy units for the duration of the Corsair II’s career. A-7s would go on to participate in every military operation undertaken by the United States in the 1980s—attacks on Lebanon and the invasion of Grenada in 1983, operations against Libya in 1985, during the “Tanker War” in the Persian Gulf in 1987, and finally in the First Gulf War in 1991. In these operations, the A-7 was able to use its pinpoint bombing ability to good use; in Libya and the Persian Gulf, Corsair IIs attacked and sank numerous Libyan and Iranian patrol boats with unguided bombs. It also was the Navy’s Wild Weasel of choice during the 1980s, using the Vietnam-era Shrike before upgrading to the far superior HARM.
In Operation Desert Storm, two A-7 squadrons from John F. Kennedy were used both to attack fixed targets with “iron” bombs and Walleyes in “tank plinking”—knocking out Iraqi tanks with precision weapons. Despite there being less than 30 A-7s in theater, these aircraft were able supplements to the USAF’s A-10s and F-111s.
The First Gulf War was the A-7’s swan song. The last squadrons gave up their Corsair IIs for F/A-18 Hornets by May 1991, ending nearly thirty years of operations. Some ex-Navy A-7s were passed on to Greece, Portugal, and Thailand, and some still remain in service with Thailand and Greece. Of the 1569 A-7s built, about half were Navy types, and today 20 former US Navy A-7s are on display as gate guards and museum pieces.
One of the last batch of Navy A-7s to be produced, 160713 would spend its entire career assigned to Atlantic Fleet squadrons. Most of its career was with VA-83 ("Rampagers"), flying off the USS Forrestal (CV-59) and USS Saratoga (CV-60). In 1988 160713 was transferred to VA-46, the famous "Clansmen," aboard first the USS Eisenhower (CVN-69) and USS Kennedy (CV-67). On the latter, the aircraft was part of the A-7's last combat deployment, as VA-46 was aboard the Kennedy during the First Gulf War, Operation Desert Storm; VA-46 was one of two remaining A-7 squadrons in 1991. When the Kennedy returned home after the war, 160713 was retired with the rest of the Navy's A-7s. Because it had participated in the last A-7 strikes, it was donated to the Pima Air and Space Museum in 1994.
160713 is in excellent condition, having just finished a restoration by the museum. It wears the overall light gray scheme carried by US Navy A-7s at the end of their career, along with the later tail marking of the Clansmen. (VA-46, during Vietnam and the 1970s, carried a spectacular Scottish clan tartan, reflecting the heritage of the squadron's first commander. As Navy colors toned down in the 1980s, this was changed to the sword-wielding hand that adorns many Scottish clan badges--including my own!) The "E" behind the cockpit indicates an Efficiency award won by the squadron on its final deployment.
The bomb markers on the nose are somewhat misleading--this does not indicate the number of missions 160713 flew during Desert Storm, but rather the total number of bombs dropped and missiles fired. Along with the several dozen bombs the aircraft dropped, it looks to have fired several AGM-88 HARM antiradar missiles and three AGM-84 Harpoon attack missiles as well.

VANDENBERG AIR FORCE BASE, Calif. – The remaining half-section of the Delta II payload fairing moves into place around NASA's Orbiting Carbon Observatory-2, or OCO-2, in the mobile service tower at Space Launch Complex 2 on Vandenberg Air Force Base in California. The fairing will protect OCO-2 during launch aboard a United Launch Alliance Delta II rocket, scheduled for 5:56 a.m. EDT on July 1. OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural "sinks" that absorb carbon dioxide and help control its buildup. The observatory will measure the global geographic distribution of these sources and sinks and study their changes over time. To learn more about OCO-2, visit oco.jpl.nasa.gov.

The Rockwell (now part of Boeing) B-1 Lancer is a four-engine, variable-sweep wing strategic bomber used by the United States Air Force. First envisioned in the 1960s as a supersonic bomber with sufficient range and payload to replace the Boeing B-52 Stratofortress, it developed primarily into a low-level penetrator with long range and supersonic speed capability.
The bomber's development was delayed multiple times over its history, as the theory of strategic balance changed from flexible response to mutually assured destruction and back again. The initial B-1A version was developed in the early 1970s, but its production was canceled and only four prototypes were built. In 1980, the B-1 resurfaced as the B-1B version with the focus on low-level penetration bombing. The B-1B entered service with the United States Air Force (USAF) in 1986.
The B-1B began service with the USAF Strategic Air Command as a nuclear bomber. In the 1990s, it was converted to conventional bombing use. It was first used in combat during Operation Desert Fox in 1998 and during the NATO action in Kosovo the following year. The B-1B continues to support U.S. and NATO military in Afghanistan and Iraq. The Lancer is the supersonic component of the USAF's long-range bomber force, along with the subsonic B-52 and Northrop Grumman B-2 Spirit. The bomber is commonly called the "Bone" (originally from "B-One"). With the retirement of the General Dynamics/Grumman EF-111A Raven in 1998 and the Grumman F-14 Tomcat in 2006, the B-1B is the U.S. military's only active variable-sweep wing aircraft.

There is an Atlas-F rocket on display at Kennedy Space Center with a dummy Agena stage on top. In reality, almost all Atlas-Agena rockets were “Atlas-D” models.
Atlas-Agena
The Atlas-Agena was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas family of rockets, and was launched 109 times between 1960 and 1978. It was used to launch the first five Mariner unmanned probes to the planets Venus and Mars, and the Ranger and Lunar Orbiter unmanned probes to the Moon. The upper stage was also used as an unmanned orbital target vehicle for the Gemini manned spacecraft to practice rendezvous and docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified DoD payloads.
The Atlas-Agena was a two-and-a-half-stage rocket, with a stage-and-a-half Atlas missile as the first stage, and an RM-81 Agena second stage. Initially, Atlas D missiles, re-designated as the LV-3, were used as the first stage. These were later replaced by the standardized Atlas SLV-3, and its derivatives, the SLV-3A and B. The final Atlas-Agena launch used an Atlas E/F.
The earliest Agena variant was the Agena A in 1959-60, which did not have restart capability. Most of these were flown on Thor-Agena boosters for the Discoverer program and only four used Atlases (Midas 1, Midas 2, Samos 1, and Samos 2), two of which failed.
Late in 1960, Lockheed introduced the uprated Agena B stage which was restartable and had longer propellant tanks for more burn time. It first flew on the Thor and did not make its maiden voyage on an Atlas for months, when Midas 3 launched on July 12, 1961. Atlas-Agenas were then used for DoD and NASA programs, but proved a reliability nightmare as one failure after another happened. In late 1962, after Ranger 5 suffered another booster malfunction (albeit a minor one that ground controllers were able to work around), NASA convened a review board which undertook a wholesale reevaluation of the Atlas-Agena as a launch vehicle. The board found that quality control and checkout procedures were poor, and that this situation was exacerbated by the several dozen configurations of the booster, as each individual DoD and NASA program necessitated custom modifications to the Atlas and Agena, and the latter also differed in its Atlas and Thor variants. The board recommended improved quality control, better hardware, and also establishing one standardized launch vehicle for all space programs.
The end result was the Atlas SLV-3 and Agena D, standardized versions of the Atlas D core and Agena B which would be the same on every launch (at least as far as the Atlas was concerned, Agena Ds often still had customized setups, especially for DoD payloads). The Agena D first flew in July 1963 for DoD launches, but NASA continued using Agena Bs for the remaining Ranger missions. The Atlas SLV-3 meanwhile first flew in August 1964. Dozens of Atlas SLV-3/Agena D boosters were flown over the following years, mostly for the KH-7 Gambit program, also for a few NASA missions. The last Atlas-Agena was flown in 1978 to launch SEASAT, but on a repurposed Atlas F missile rather than the SLV-3.
Launches were conducted from Launch Complexes 12, 13 and 14 at the Cape Canaveral Air Force Station, and Launch Complexes 1 and 2 at Point Arguello (now SLC-3 and 4 at Vandenberg Air Force Base).

Destruct System
All Atlas-Agena vehicles contained an Inadvertent Separation Destruct System to destroy the Agena in the event that it separated prematurely from the Atlas, a situation that could be caused by a booster hard-over or if the Atlas self-destructed in flight. The ISDS charges were mounted on the adapter section between the two vehicles and would activate if a series of tripwires were broken. During the coasting period between staging, the ISDS charges were disabled. The Atlas’s own RSO charges were also wired so that they would destroy both vehicles if activated. Most Agenas also had their own separate RSO charges, although NASA planetary probes omitted them for weight-saving reasons and due to the flight trajectory used, which meant that destruct of the Agena was no longer possible following staging.
Two Atlas-Agena flights involved an intentional destruct of the Atlas (Mariner 1 and Canyon 4) while two others (Midas 6 and Midas 8) resulted in an ISDS destruction of the Agena following in-flight malfunction and self-destruct of the Atlas.
The Gemini-Agena Target Vehicle had a specially modified Range Safety destruct system designed to fire slugs into the propellant tanks rather than the conventional method of rupturing them externally, since an inadvertent activation of the RSO system in orbit could endanger the Gemini astronauts.
The very first Atlas-Agena flight, Midas 1 in February 1960, failed when the unproven ISDS system mistakenly activated at staging, rupturing the Atlas’s LOX tank and causing the breakup of the Agena. The ISDS system was redesigned afterwards and this failure mode did not repeat itself.
Production Launches
Ranger
Ranger block I spacecraft bus was used for the first two Rangers, and also for the first two Mariner interplanetary probes.
The Ranger spacecraft were designed to impact the Moon, returning photographs of the lunar surface until their destruction. The spacecraft was designed in three Blocks, all similar in appearance with a forward antenna and magnetometer, supported by a boom, with more sensors and two solar panels and a dish antenna mounted at the base. The first two Block I spacecraft, Ranger 1 and Ranger 2, were launched on August 23 and November 18, 1961, not to the Moon, but in intended high Earth orbits to test the Atlas-Agena and spacecraft capabilities. However, the Agena malfunctioned on both flights and left the probes trapped in a useless low Earth orbit from which they soon decayed.
The Block II missions, Ranger 3, Ranger 4, and Ranger 5, were launched away from Earth in January, April, and October 1962, but all three failed due to either malfunctions of the probe or launch vehicle difficulties. Ranger 3 missed the Moon entirely. Ranger 4’s solar panels failed to deploy, and the navigation system failed, sending the probe to impact the lunar far side without returning any pictures or data. Ranger 5 suffered an unknown failure which deprived it of power, and it missed the Moon by 725 kilometers (391 nautical miles).
Ranger 6, launched January 30, 1964, successfully impacted the Moon but its cameras failed to return pictures. The last three Rangers were finally successful: Ranger 7 in July 1964, Ranger 8 in February 1965, and Ranger 9 in March 1965.
Mariner
The Mariner spacecraft were built by NASA’s Jet Propulsion Laboratory. Mariner 1 and Mariner 2 were twins, launched on July 22 and August 27, 1962, to fly by the planet Venus. The first two craft used the same spacecraft bus as the Block I Rangers, each weighing 446 pounds (202 kg) and instrumented to perform radiometric temperature measurements of the planet, and to measure interplanetary magnetic fields and particles. Mariner 1’s Atlas-Agena malfunctioned and went off course, requiring its destruction approximately 5 minutes after liftoff. Mariner 2 successfully made the 3½-month flight, becoming the first spacecraft to fly by another planet. It carried microwave and infrared radiometers, and sensors for cosmic dust, solar plasma and high-energy radiation, and magnetic fields.
Mariner 3 and Mariner 4 used a redesigned spacecraft bus weighing 575 pounds (261 kg), and were launched on November 5 and November 28, 1964 to fly by the planet Mars. Mariner 3 failed after a successful launch when its payload shroud failed to open. These Mariners carried cameras, and Mariner 4 successfully returned pictures of Mars as it flew by.
The 540-pound (240 kg) Mariner 5 was successfully launched to Venus on June 14, 1967 and flew by in October, probing Venus’ atmosphere with radio waves, scanning its brightness in ultraviolet light, and sampling solar particles and magnetic field fluctuations above the planet.
Gemini
The Agena rocket stage was used as the passive docking target for the Gemini manned space program. After docking, the Agena could also be fired by the astronauts to raise the combined Gemini-Agena spacecraft into a higher orbit. The first attempt at such a docking mission was made for the Gemini 6 mission on October 25, 1965, but the Agena suffered an engine failure and did not reach orbit. This forced postponement and replanning of the Gemini 6A mission, which performed rendezvous with Gemini 7 without docking.
The GATV was first successfully launched for Gemini 8 on March 16, 1966, permitting the first successful docking in space. GATV-8 was later used as the secondary Agena target for Gemini 10, which also docked with its own GATV. GATV-9 failed to orbit when the Atlas suffered a control malfunction, forcing a similar reschedule of the Gemini 9A mission using a backup Augmented Target Docking Adapter atop an Atlas, but with no Agena rocket stage. Two more GATVs were successfully launched and used on Gemini 11 and Gemini 12.
Lunar Orbiter
A series of five Lunar Orbiter spacecraft were launched from August 1966 through August 1967, to help select landing sites for the Apollo manned lunar landing program by mapping the Moon’s surface. Each spacecraft weighed 850 pounds (390 kg) and was 4.9 feet (1.5 m) in diameter, minus the four extended solar panels. All launches were successful, and a total of 99 percent of the surface of the Moon (near and far side) was mapped with resolution as high as 3 ft. 3 in (1 meter). Altogether the Orbiters returned 2180 high resolution and 882 medium resolution frames. The spacecraft also carried micrometeroid sensors, which showed the average micro-meteoroid flux near the Moon to be two orders of magnitude greater than in interplanetary space, but slightly less than the near-Earth environment.
OAO
Orbiting Astronomical Observatory was a series of NASA satellites flown between 1966 and 1972 for astronomy studies. The first OAO (launched April 8, 1966) used a one-off Atlas variant, mating an Agena D to the LV-3C variant of the Atlas and encased in a Centaur-type payload shroud. The remaining three launches used actual Atlas-Centaur vehicles.
ATS
Applications Technology Satellite was a series of NASA satellites flown in 1967-69 to perform various technology tests. Only the first ATS was launched on an Atlas-Agena, the remainder using Atlas-Centaurs. ATS-1 was a partial failure when the Agena failed to restart, leaving it in LEO.
OGO
Orbiting Geophysical Observatory was a series of NASA satellites flown between 1964 and 1969 for magnetosphere studies. These satellites used several different booster types, including Thor-Agenas. Five of them used Atlas-Agenas, and OGO 5 (launched March 4, 1968) was the sole civilian use of the Atlas SLV-3A Agena.
Midas
Missile Defense Alarm System was a series of Air Force satellites flown between 1960 and 1966 for infrared detection of ballistic missile exhaust plumes on Atlas-Agena A, B, and D. There were several failures and overall program performance was poor, but it would give way to the more successful DSP satellites.
Samos
Samos was a series of Air Force satellites flown between 1960 and 1962 for photoreconnaissance on Atlas-Agena A and B. There were several failures, including an on-pad explosion of an Atlas, and the program was cancelled at the end of 1962 without ever demonstrating any operational capability.
Gambit
KH-7 Gambit was a series of Air Force satellites flown between 1963 and 1966 for photoreconnaissance on Atlas-Agena D. Although there were a number of mission failures, Gambit overall was highly successful in comparison with the bungled Samos program and it returned high-value area reconnaissance of the USSR and China before giving way to KH-8 Gambit in 1967.
Rhyolite/Canyon
Rhyolite/Canyon was a series of Air Force satellites flown between 1968 and 1978 for SIGNIT intelligence on Atlas SLV-3A Agena. One Canyon mission failed when its Atlas went off course and had to be destroyed. These were the final launches of Atlas-Agena vehicles aside from the one-off Atlas F/Agena used to launch Seasat.
Vela
Vela consisted of two sets of Air Force satellites flown in 1964-65 to monitor Soviet compliance with the Nuclear Test Ban Treaty on Atlas-Agena Ds.
Snapshot
Snapshot was a one-off Air Force test of a nuclear satellite flown in 1965 on an Atlas-Agena D.
Technicians with Orbital ATK install the payload adapter to the deployment module that contains the micro satellites for NASA's Cyclone Global Navigation Satellite System (CYGNSS) in Building 1555 at Vandenberg Air Force Base in California. CYGNSS is being prepared at Vandenberg, and then will be transported to NASA''s Kennedy Space Center in Florida aboard the Orbital ATK Pegasus XL rocket which will be attached to the Orbital ATK L-1011 carrier aircraft. CYGNSS will launch on the Pegasus XL rocket from the Skid Strip at Cape Canaveral Air Force Station. CYGNSS will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes. The data that CYGNSS provides will enable scientists to probe key air-sea interaction processes that take place near the core of storms, which are rapidly changing and play a critical role in the beginning and intensification of hurricanes.
Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, former NASA astronaut Dan Tani, who now is senior director of Missions and Cargo Operations for Orbital ATK in Dulles, Virginia, participates in a press interview. In the background is the Cygnus spacecraft scheduled to deliver hardware and supplies to the International Space Station on the upcoming Orbital ATK Commercial Resupply Services-6 mission.
