Project Oxcart established. The A-12 design, a combination of their A-7 and A-11 submissions, emphasized low radar cross section, extremely high altitude and high-speed performance. Earlier, on 3 September, Project GUSTO was concluded and Project OXCART, to build the A-12, was begun. [57]
The General Dynamics/McDonnell Douglas A-12 Avenger II was a proposed American attack aircraft from General Dynamics and McDonnell Douglas. It was to be an all-weather, carrier-based stealth bomber replacement for the Grumman A-6 Intruder in the United States Navy and Marine Corps .
Kelly" Johnson and his team at Lockheed's Skunk Works were assigned to produce the A-12 (or OXCART), which operated at high altitude of 70,000 to 80,000 ft (21,000 to 24,000 m) and speed of Mach 3.2 (2,400 mph; 3,800 km/h) to avoid radar detection. Various plane shapes designed to reduce radar detection were developed in earlier prototypes ...
A-12 Shrike, a World War 2–era American attack aircraft; Abrial A-12 Bagoas, a French experimental glider of the 1930s; Aero A.12, a Czechoslovak light bomber built after World War I; Lockheed A-12, codenamed Oxcart, a high-altitude, high-speed reconnaissance aircraft, manufactured for the CIA
A bullock cart or ox cart (sometimes called a bullock carriage when carrying people in particular) is a two-wheeled or four-wheeled vehicle pulled by oxen. It is a means of transportation used since ancient times in many parts of the world. They are still used today where modern vehicles are too expensive or less suitable for the local ...
The Lockheed YF-12 is an American Mach 3+ capable, high-altitude interceptor prototype, developed and manufactured by American aerospace company Lockheed Corporation.. The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).
