The first flight of an SR-71 took place on 22 December 1964, at USAF Plant 42 in Palmdale, California, piloted by Bob Gilliland. [ 121 ] [ 122 ] The SR-71 reached a top speed of Mach 3.4 during flight testing, [ 123 ] [ 124 ] with pilot Major Brian Shul reporting a speed in excess of Mach 3.5 on an operational sortie while evading a missile ...
25 July 1964: President Johnson makes public announcement of SR-71. 29 October 1964: SR-71 prototype (#61-7950) delivered to Palmdale. 22 December 1964: First flight of the SR-71 with Lockheed test pilot Bob Gilliland at AF Plant #42. First mated flight of the MD-21 with Lockheed test pilot Bill Park at Groom Lake.
Lockheed SR-71 Blackbird; Initially developed as A-12 by Central Intelligence Agency; first flight took place at Groom Lake , Nevada, on 25 April 1962. USAF developed SR-71 from CIA design; first flight took place on 22 December 1964. Operational use of SR-71 began in 1968. Retired in 1989 due to budget reductions.
Several years later, the U.S. Air Force became interested in the design, and it ordered the SR-71 Blackbird, a two-seater version of the A-12. This aircraft first flew in 1966 and remained in service until 1998. The D-21 drone, similar in design to the Blackbird, was built to overfly the Lop Nur nuclear test facility in China. This drone was ...
The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [1] which also ratifies any claims. Speed records ...
Among the legendary planes it produced were the U-2 reconnaissance aircraft, which could fly up to 70,000 feet and took its maiden flight in 1956, and the A-12 Oxcart, a precursor to the SR-71 ...
He is recognized for his contributions to a series of important aircraft designs, most notably the Lockheed U-2 and SR-71 Blackbird. Besides the first production aircraft to exceed Mach 3, he also produced the first fighter capable of Mach 2, the United States' first operational jet fighter, as well as the first fighter to exceed 400 mph, and ...
NASA was loaned 2 SR-71 aircraft for research work. One was modified to flight-test a Linear Aerospike rocket engine and was fitted with thrust-enhanced J58 engines. [5] Engine thrust was increased by 5% to offset increased aircraft drag. The increased thrust came from a throttle push, or exhaust gas temperature uptrim, of 75 °F (42 °C).
