Question: What short lived aircraft, produced for the United States Air Force, is based on a fighter plane armed with four 20 mm cannons?

<P0-S0> The incident started as a routine training flight. <P0-S1>  Colonel Nikolai Skuridin, the pilot, departed from the Soviet Bagicz Airbase near Kołobrzeg, Poland. <P0-S2>  During takeoff, the afterburner failed and the engine began losing power. <P0-S3>  At an altitude of 150 meters and descending, the pilot assumed he had a complete engine failure and ejected without incident. <P0-S4>  The engine had not failed completely, and the aircraft remained airborne, flying on autopilot in a westerly direction. <P0-S5>  The unmanned aircraft left Polish airspace, crossing into the airspace of East Germany and then West Germany, where it was intercepted by a pair of U.S. Air Force F-15s of the 32d Tactical Fighter Squadron, of the United States Air Forces Europe, stationed at Soesterberg Air Base in the Netherlands. <P0-S6>  As the MiG-23 crossed into Dutch airspace the F-15 pilots reported the plane having no pilot, radioing ""There is definitely no pilot in the plane"" and continuing the intercept into Belgian airspace. <P0-S7>  The escorting F-15s were instructed to down the plane over the North Sea. <P0-S8>  As the MiG ran out of fuel, it started a slow turn to the south. <P0-S9>  The French Air Force put armed Mirage fighters on readiness in case the MiG approached French territory. <P0-S10>  After flying over 900 km the MiG crashed into a house, killing a Belgian teenager. <SEP> <P1-S0> The Northrop P-61 Black Widow, named for the American spider, was the first operational U.S. warplane designed as a night fighter, and the first aircraft designed to use radar. <P1-S1>  The P-61 had a crew of three: pilot, gunner, and radar operator. <P1-S2>  It was armed with four 20 mm (.79 in) Hispano M2 forward-firing cannons mounted in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns mounted in a remote-controlled dorsal gun turret. <SEP> <P2-S0> The Beechcraft T-6 Texan II is a single-engine turboprop aircraft built by the Raytheon Aircraft Company (which became Hawker Beechcraft and later Beechcraft Defense Company, and was bought by Textron Aviation in 2014). <P2-S1>  A trainer aircraft based on the Pilatus PC-9, the T-6 has replaced the Air Force's Cessna T-37B Tweet and the Navy's T-34C Turbo Mentor. <P2-S2>  The T-6A is used by the United States Air Force for basic pilot training and Combat Systems Officer (CSO) training and by the United States Navy and United States Marine Corps for primary Naval Aviator training as well as primary and intermediate Naval Flight Officer (NFO) training. <P2-S3>  The T-6A is also used as a basic trainer by the Royal Canadian Air Force (CT-156 Harvard II), the Greek Air Force, the Israeli Air Force ("Efroni"), and the Iraqi Air Force. <P2-S4>  The T-6B is the primary trainer for U.S. student naval aviators. <P2-S5>  The T-6C is used for training by the Mexican Air Force, Royal Air Force, Royal Moroccan Air Force, and the Royal New Zealand Air Force. <SEP> <P3-S0> The Northrop F-15 Reporter (later RF-61) was an American unarmed photographic reconnaissance aircraft. <P3-S1>  Based on the Northrop P-61 Black Widow night fighter, it was the last piston-powered photo-reconnaissance aircraft designed and produced for the United States Air Force. <P3-S2>  Though produced in limited quantities, and with a relatively short service life, the F-15's aerial photographs of the Korean Peninsula would prove vital in 1950, when North Korea invaded the south.
