Douglas Aircraft Company's Model 2229 was a proposed supersonic transport (SST) originally started as a private study. The design progressed as far as making mock-ups of the cockpit area and wind-tunnel models of the overall layout. After studying the design, Douglas concluded that the SST would not work economically, and declined to enter the ...
The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. It was intended to be much larger and faster than competing supersonic transport (SST) designs such as the Concorde. The SST was the topic of considerable concern within and outside the aviation industry.
Artist's concept of an L-2000 in Pan Am livery at altitude in full afterburner (top), and with landing gear extended. The new design was designated L-2000-1 and was 223 ft (70 m) long with a narrow-body 132 in (335.2 cm) wide fuselage to meet aerodynamic requirements, allowing for passenger seating of five abreast seating in coach and a four-abreast arrangement in first-class seating.

A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound in terms of air speed. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144 .
The Lockheed Martin X-59 Quesst ("Quiet SuperSonic Technology"), sometimes styled QueSST, is an American experimental supersonic aircraft under development by Skunk Works for NASA's Low-Boom Flight Demonstrator project. [2] Preliminary design started in February 2016, with the X-59 planned to begin flight testing in 2021.
The XB-1 began taxi tests in December 2022, [3] and conducted its maiden flight on March 22, 2024. [1] The aircraft performed its first supersonic flight test on January 28, 2025, being the first privately developed aircraft to do so. [4] It made a second supersonic flight on February 10, 2025, after which the demonstrator aircraft was retired. [5]
The Bede BD-10 was Jim Bede's attempt to introduce the world's first kit-built jet-powered general aviation supersonic aircraft. [1] After several years of testing and modifications, the project was taken over by investors in order to produce fully completed civilian and military training aircraft, but these projects were never realized.
