In 2018, company executives said an SR-72 test vehicle could ...
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.
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.

It set and held speed and altitude world records of over 2,000 miles per hour (3,200 km/h) and over 80,000 feet (24,000 m) (later surpassed by the closely related SR-71 Blackbird), and is the world's largest, heaviest and fastest crewed interceptor. [1]
By the late 1980s, many aerospace industry observers believed that the U.S. had the technological capability to build a Mach 5 (hypersonic speed) replacement for the aging Lockheed SR-71 Blackbird. Detailed examinations of the U.S. defense budget claimed to have found money missing or channeled into black projects. [8]
