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.
The information and experience Johnson gained was later used to produce the A-12 spy plane for the Central Intelligence Agency. Johnson then used the combined knowledge of the Kingfisher and A-12 to produce the SR-71 Blackbird. [16] Johnson also led the development of the SR-71 Blackbird family of aircraft. Through a number of significant ...
The United States became a leader in development of aircraft specifically designed for the reconnaissance role; examples include the Lockheed SR-71, Lockheed U-2, Republic XF-12, and Hughes XF-11 (the latter two did not enter production).
Lockheed SR-71 The Pratt & Whitney J58 (company designation JT11D-20 ) is an American jet engine that powered the Lockheed A-12 , and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine-engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
