The McDonnell XF-85 Goblin is an American prototype fighter aircraft conceived during World War II by McDonnell Aircraft. It was intended to deploy from the bomb bay of the giant Convair B-36 bomber as a parasite fighter. The XF-85's intended role was to defend bombers from hostile interceptor aircraft, a need demonstrated during World War II. McDonnell built two prototypes before the Air Force (USAAF) terminated the program.
The Curtiss-Wright XP-55 Ascender is a 1940s United States prototype fighter aircraft built by Curtiss-Wright. Along with the Vultee XP-54 and Northrop XP-56, it resulted from United States Army Air Corps proposal R-40C issued on 27 November 1939 for aircraft with improved performance, armament, and pilot visibility over existing fighters; it specifically allowed for unconventional aircraft designs. An unusual design for its time, it had a canard configuration, a rear-mounted engine, swept wings, and two vertical tails. Because of its pusher design, it was sarcastically referred to as the "Ass-ender". Like the XP-54, the Ascender was designed for the Pratt & Whitney X-1800 engine, but was re-designed after that engine project was canceled. It was also the first Curtiss fighter aircraft to use tricycle landing gear.
The Vultee P-66 Vanguard was a United States Army Air Forces fighter aircraft. It was initially ordered by Sweden, but by the time the aircraft were ready for delivery in 1941, the United States would not allow them to be exported, designating them as P-66s and retaining them for defensive and training purposes. Eventually, a large number were sent to China where they were pressed into service as combat aircraft with mixed results.
The Boeing B-29 Superfortress is a WWII era long range, strategic heavy bomber that was produced in many experimental and production models.
Aphrodite and Anvil were the World War II code names of United States Army Air Forces and United States Navy operations to use Boeing B-17 Flying Fortress and Consolidated PB4Y bombers as precision-guided munitions against bunkers and other hardened/reinforced enemy facilities, such as "Crossbow" operations against German long range missiles.
The Short SA.4 Sperrin was a British jet bomber design of the early 1950s, built by Short Brothers and Harland of Belfast. It first flew in 1951. From the onset, the design had been viewed as a fall-back option in case the more advanced strategic bomber aircraft, then in development to equip the Royal Air Force's nuclear-armed V bomber force, experienced delays; the Sperrin was not put into production because these swept-wing designs, such as the Vickers Valiant, were by then available.
The Chase XCG-20, also known as the XG-20 and by the company designation MS-8 Avitruc, was a large assault glider developed immediately after World War II by the Chase Aircraft Company for the United States Air Force, and was the largest glider ever built in the United States. The XG-20 did not see production due to a change in USAF requirements, however, it was modified into the successful Fairchild C-123 Provider twin-engined transport aircraft which saw extensive service in the Vietnam War.
The Grumman XSBF, also known by the company designation G-14, was an American biplane scout bomber developed by Grumman Aircraft for the United States Navy during the 1930s. Derived from Grumman's successful "Fifi" fighter, the aircraft was developed at a time when the biplane was giving way to the monoplane. In competition against other aircraft it proved to possess inferior performance in its intended role, and did not enter production. The sole prototype went on to serve as a liaison aircraft, as well as being used in experiments by NACA, before being destroyed in a crash in 1939.
The Great Lakes BG was an American carrier-based dive bomber of the 1930s. Designed and built by the Great Lakes Aircraft Company of Cleveland, Ohio, 61 were used by the United States Navy and United States Marine Corps from 1934 to 1940.
The Fletcher FBT-2 was a military trainer aircraft built in the United States in the early 1940s. Although it was never entered production as a trainer, it was ordered in small numbers as a target drone but when that was cancelled played a small part in the development of guided bombs.
The Lavochkin La-152,, and its variants, was a jet fighter prototype designed and manufactured by the Lavochkin Design Bureau (OKB) shortly after the end of World War II. Derived from the Lavochkin La-150, the 152 used several different engines, but the program was canceled as other fighters with more powerful engines and swept wings showed more promise.
The Cornelius XFG-1 was an American military fuel transporting towed glider, without a tailplane and with a forward-swept wing. Two were built but development ended in 1945.
The Chase XC-123A was an experimental transport aircraft developed by Chase Aircraft. The first jet-powered transport built for the United States Air Force, it was intended for use as a high-speed transport for high-priority cargo and personnel. The XC-123A was determined to have insufficient advantages over existing types in service, and did not go into production. The sole prototype was converted into the piston-powered Stroukoff YC-123D to evaluate boundary layer control systems.
The Fairchild BQ-3, also known as the Model 79, was an early expendable unmanned aerial vehicle – referred to at the time as an "assault drone" – developed by Fairchild Aircraft from the company's AT-21 Gunner advanced trainer during the Second World War for use by the United States Army Air Forces. Two examples of the type were built and flight-tested, but the progress of guided missiles rendered the assault drone quickly obsolete, and the type was not produced.
The Pratt-Read LBE-1 was a prototype glide bomb, or "Glomb", developed for the United States Navy during World War II. Although there were high hopes for the concept, the limitations of the Glomb led to the production contract for the LBE-1 being reduced, then cancelled, and only four examples of the type were ever built.
The Piper LBP was a glide bomb, or "Glomb", developed by Piper Aircraft for the United States Navy during World War II. Developed as one of three "Glomb" aircraft, the inherent limitations of the Glomb and the technology of the time, combined with difficulties encountered in testing of the prototype, led to the production contract for the LBP-1 being reduced, then cancelled, with none of the Glomb aircraft ever seeing operational service.
Glomb, from "glide bomb", was a project undertaken by the United States Navy during World War II to develop an unmanned aircraft for delivering bombs to high-value, well-protected targets without risk to aircrew. The project proceeded through the war, producing several prototype aircraft, but technical limitations meant no Glombs saw operational service and the program was cancelled at the end of the war.
The Taylorcraft LBT was a glider designed and built by Taylorcraft during World War II, in response to a United States Navy requirement for a glide bomb. One of three prototype "Glomb" models ordered by the Navy, the LBT suffered from technical and performance difficulties, and was cancelled early in production, none of the aircraft seeing operational service.
The XSSM-A-5 Boojum, also known by the project number MX-775B, was a supersonic cruise missile developed by the Northrop Corporation for the United States Air Force in the late 1940s. Intended to deliver a nuclear warhead over intercontinental range, the project was determined to be too ambitious given technical difficulties with the SM-62 Snark which it was planned to follow, and it was canceled in 1951.
The Fletcher BG-2 was a proposed American bomb glider designed by Fletcher Aviation in World War II.
