The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA.

The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
The SR-71 was the world's fastest and highest-flying air-breathing operational manned aircraft throughout its career and it still holds that record. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m).
Uncrewed torpedo speed claims range from 60 knots (110 km/h; 69 mph) for the British Spearfish torpedo [64] to 200 knots (370 km/h; 230 mph) for the Russian VA-111 Shkval.

The plane would later achieve a speed of just over 2,000 miles per hour, nearly 50% faster than Concorde. “The overall design of the XB-70 was a thing of beauty,” says Tony Landis, a historian ...
The Guinness Book of World Records lists the Soviet Tupolev Tu-95 bomber and its derivatives (Tu-114 and Tu-142) as "the fastest propeller-driven aircraft in standard production form", with a maximum cruise speed of 925 km/h (575 mph; 499 kn) or Mach 0.82.
The first unconfirmed reports about the SR-72 appeared in 2007, when various sources said Lockheed Martin was developing an airplane able to fly six times the speed of sound or Mach 6 (4,000 mph; 6,400 km/h; 3,500 kn) for the Air Force [4] [5] —about twice as fast as the SR-71.
