This equates to an average speed of about Mach 2.72, including deceleration for in-flight refueling. Peak speeds during this flight were likely closer to the declassified top speed of over Mach 3.2. For comparison, the best commercial Concorde flight time was 2 hours 52 minutes and the Boeing 747 averages 6 hours 15 minutes.
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.
While some editors may hold that the Global Hawk is the SR-71's replacement I would point out that the Hawk has a top speed of around 400 mph while the SR-71 has been clocked at over 2,190 mph. The Hawk has no stealth capability whatsoever and it has a ceiling of 65,000 feet while the SR-71 has a measure of stealth and a ceiling of over 85,000 ...
5 February 1968: Lockheed ordered to destroy A-12, YF-12 and SR-71 tooling. 8 March 1968: First SR-71A (#61-7978) arrives at Kadena AB to replace A-12s. 21 March 1968: First SR-71 (#61-7976) operational mission flown from Kadena AB over Vietnam. 8 May 1968: Jack Layton flies last operational A-12 sortie, over North Korea.
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 ...
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 ...
Major General Eldon Wayne Joersz (born February 5, 1944) is an American pilot, who jointly holds the World Air Speed Record. Joersz and Ltc George T. Morgan Jr. set the air speed record on July 28, 1976, in SR-71A Blackbird 61-7958 at Beale Air Force Base .
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".
