The Boeing XB-15 was a United States bomber aircraft designed in 1934 as a test for the United States Army Air Corps (USAAC) to see if it would be possible to build a heavy bomber with a 5,000 mi (8,000 km) range. For a year beginning in mid-1935 it was designated the XBLR-1. When it first flew in 1937, it was the most massive and voluminous airplane ever built in the US. It set a number of load-to-altitude records for land-based aircraft, including carrying a 31,205 lb (14,154 kg) payload to 8,200 ft (2,500 m) on 30 July 1939.
The Advanced Aeromarine Sierra was an American high-wing, strut-braced, single-seat, glider that was designed and produced by Advanced Aeromarine, as a kit for amateur construction.
The Boeing Pelican ULTRA was a proposed ground effect fixed-wing aircraft under study by Boeing Phantom Works in the early 2000s.
The Kawasaki Ki-60 was an experimental Japanese pre-World War II fighter aircraft that used a license-built (Kawasaki) DB 601 liquid-cooled engine. This was at that time an unusual choice because the majority of Japanese aircraft at that time used air-cooled radial engines.
The Northrop AGM-137 TSSAM was a standoff cruise missile developed for the three branches of the United States Armed Forces, hence "tri-service". Missile development began in 1986 but revelation of cost-overruns in 1991 prompted the Army to pull out of the project and an investigation of the procurement process by the General Accounting Office. The TSSAM program was eventually cancelled in December 1994 pursuant to a GAO recommendation and the loss of support of the United States Army after going as far as several test launches.
The Yakovlev Yak-46 was a proposed aircraft design based on the Yak-42 with two contra-rotating propellers on the propfan located at the rear. The specification of the Samara turbofans was in the 11,000 kg thrust range. Though proposed in the 1990s, production of the Yak-46 never commenced.
The Beechcraft Queen Air is a twin-engined light aircraft produced by Beechcraft in numerous versions from 1960 to 1978. Based upon the Twin Bonanza, with which it shared key components such as wings, engines, and tail surfaces, it had a larger fuselage, and served as the basis for the highly successful King Air series of turboprop aircraft. Its primary uses have been as a private aircraft, utility, and small commuter airliner. Production ran for 17 years.
The Tachikawa Ki-36 was a Japanese army co-operation aircraft of World War II. It was a two-seat, low-wing monoplane with a single piston engine and fixed, tailwheel-type undercarriage.
The Tachikawa Ki-55 was a Japanese advanced trainer.
The Kawasaki Ki-48, was a Japanese twin-engine light bomber that was used during World War II. Its Allied reporting name was "Lily".
The Farman HF.20 and its derivatives were a family of reconnaissance aircraft produced in France shortly before and during the First World War. It was a refined version of the Farman MF.11 "Shorthorn" that did away with the type's distinctive landing skids, and incorporated design features from Henri Farman's designs. It entered service with the French, Belgian and Serbian armies in 1913, and with the British RFC and RNAS shortly after the outbreak of war. The type was also licence-built in the UK by Airco and Grahame-White.
The Hafner Rotabuggy was a British experimental aircraft that was essentially a Willys MB combined with a rotor kite, developed with the intention of producing a way of air-dropping off-road vehicles.
The Stipa-Caproni, also known as the Caproni Stipa, was an experimental Italian aircraft designed in 1932 by Luigi Stipa (1900–1992) and built by Caproni. It featured a hollow, barrel-shaped fuselage with the engine and propeller completely enclosed by the fuselage—in essence, the whole fuselage was a single ducted fan. Although the Regia Aeronautica was not interested in pursuing development of the Stipa-Caproni, its design influenced the development of jet propulsion.
The Tupolev MTB-2, also known as the ANT-44, was a Soviet four-engine flying boat built in the late 1930s. Two prototypes were built; performance was satisfactory, but the design was overtaken by the fielding of long-range, land-based bombers by Soviet Naval Aviation and cancelled in 1940.
The IPTN N-250 was a turboprop regional airliner designed by Indonesian firm IPTN. This aircraft was IPTN's first major effort to win the market share of the regional turboprop class of 64–68 seat airliners. The aircraft's development was eventually terminated after the Asian financial crisis of 1998.
The Bréguet 890 Mercure was a late 1940s French cargo and passenger transport aircraft designed by Bréguet Aviation. Three variants were produced including a military variant called the Mars but none entered production.
The Armored Gun System (AGS) was a U.S. Army competition in the 1990s to design a light tank to replace the M551 Sheridan and TOW-equipped HMMWVs. It was the ultimate incarnation of several research programs run in the 1970s with the aim of providing air-mobile light infantry forces with the firepower needed to last in the battlefield.
The Bilsam Ultra Cruiser is a family of Polish microlight aircraft designed and produced by Bilsam Aviation of Poznań, introduced in the 2000s. The aircraft is supplied as a complete ready-to-fly-aircraft, as a kit and in the form of plans for amateur construction.
EKIP is the Soviet and Russian project of a multifunctional aerodrome-free aircraft, built according to the "flying wing" scheme, with an elliptically shaped fuselage. Also known by its Russian nickname of Tarielka, the EKIP can land on water or unpaved ground through the use of an air cushion instead of a wheeled undercarriage. The EKIP is a short takeoff and landing (STOL) aircraft.
The Centurion C-RAM, also called the Land Phalanx Weapon System (LPWS), is an American Counter-Rocket, Artillery, and Mortar (C-RAM) air defense artillery system. The system was developed in 2004, during and after the Iraq War identified a weakness in ground-based anti-projectile artillery. The system is produced by Northrop Grumman, Raytheon, and Oshkosh Corporation.
