In the 21st century some supersonic airliners and business jets (Aerion SBJ, HyperMach SonicStar, Next Generation Supersonic Transport, Tupolev Tu-444, Gulfstream X-54, LAPCAT, Reaction Engines A2, Zero Emission Hyper Sonic Transport) were under development.

In May 2008, it was reported that Aerion Corporation had $3 billion of pre-order sales on its Aerion SBJ supersonic business jet.

Supersonic Aerospace International's Quiet Supersonic Transport is a 12 passenger design from Lockheed Martin that is to cruise at Mach 1.6, and is to create a sonic boom only 1% as strong as that generated by Concorde.

Transferred to NASA in the early 1960s, one was used as a testbed for the American supersonic transport program, fitted with an ogival wing platform (the type eventually used on Concorde; data from the program was shared with the European designers).
In 1963, the United States was considering pursuing a program to create a supersonic transport (SST) to rival the British and French Concorde.
Sonic Boom Tests Reactions, 1961-1962 – Public opinion measurement for the infamous sonic boom tests over Oklahoma City, which were intended to measure the impact of supersonic transports (SSTs) over populated areas.
By 1956 there was enough official interest in this research for the Supersonic Transport Aircraft Committee, or STAC, to be formed under Sir Morien Morgan to investigate the creation of a supersonic transport.
