The Lockheed SR-71 "Blackbird" is a retired long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft developed and manufactured by the American aerospace company Lockheed Corporation. [N 1] Its nicknames include "Blackbird" and "Habu". [1] The SR-71 was developed in the 1960s as a black project by Lockheed's Skunk Works division.
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.
The Lockheed Martin SR-72, colloquially referred to as "Son of Blackbird", [1] is an American hypersonic UAV concept intended for intelligence, surveillance and reconnaissance (ISR) proposed privately in 2013 by Lockheed Martin as a successor to the retired Lockheed SR-71 Blackbird. In 2018, company executives said an SR-72 test vehicle could ...
Some stealth aircraft have skin that is radar transparent or absorbing, behind which are structures termed reentrant triangles. Radar waves penetrating the skin get trapped in these structures, reflecting off the internal faces and losing energy. This method was first used on the Blackbird series: A-12, YF-12A, Lockheed SR-71 Blackbird.
The aircraft incorporated features that were later referred to as low observables or stealth technology. When SR-71 crews became upset that engineers were not putting enough effort into solving a constant problem with violent engine unstarts in flight, Rich considered taking a flight in the SR-71 to experience the phenomenon himself, which ...
Skunk Works engineers subsequently developed the U-2, SR-71 Blackbird, F-117 Nighthawk, F-22 Raptor, and F-35 Lightning II, the latter being used in the air forces of several countries. The Skunk Works name was taken from the "Skonk Oil" factory in the comic strip Li'l Abner .
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. 28 December 1966: Decision to terminate A-12 program by June 1968. 31 May 1967: A-12s conduct Black Shield operations out of Kadena; 3 November 1967: A-12 and SR-71 ...
The RQ-180 addresses a need for conducting penetrating ISR missions into defended airspace, a mission that was left unattended with the retirement of the Lockheed SR-71 Blackbird in 1999. It is equipped with an AESA radar and passive electronic surveillance measures, and may be capable of conducting electronic attack missions. The RQ-180 shows ...
