SR-71 Blackbird assembly line at Skunk Works. The SR-71 designation is a continuation of the pre-1962 bomber series; the last aircraft built using the series was the XB-70 Valkyrie. However, a bomber variant of the Blackbird was briefly given the B-71 designator, which was retained when the type was changed to SR-71. [18]
The Lockheed Martin SR-72, colloquially referred to as "Son of Blackbird", [1] is an American hypersonic 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 fly ...
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.
SR-71 Blackbird Clarence Leonard " Kelly " Johnson (February 27, 1910 – December 21, 1990) was an American aeronautical and systems engineer . He is recognized for his contributions to a series of important aircraft designs, most notably the Lockheed U-2 and SR-71 Blackbird .
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.
The first of those occurred 31 October 1997. The SR-71 took off at 8:31 a.m. (Pacific Standard Time-PST). [2] The aircraft flew for 1:50 hour, reaching Mach 1.2 and an altitude of 33,000 feet (10,000 m), landing at Edwards AFB. The result validated the SR-71/pod configuration. [3]
It was the precursor to the twin-seat U.S. Air Force YF-12 prototype interceptor, M-21 launcher for the D-21 drone, and the SR-71 Blackbird, a slightly longer variant able to carry a heavier fuel and camera load. The A-12 began flying missions in 1967 and its final mission was in May 1968; the program and aircraft were retired in June.
Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some fighter jets are capable of supercruise but only at high altitudes and in a clean configuration, so the term may imply "a significant increase in effective combat speed with a full weapons load over existing types".
