The High Speed Civil Transport (HSCT) was the focus of the NASA High-Speed Research (HSR) program, which intended to develop the technology needed to design and build a supersonic transport that would be environmentally acceptable and economically feasible. The aircraft was to be a future supersonic passenger aircraft, baselined to cruise at Mach 2.4, or more than twice the speed of sound. The project started in 1990 and ended in 1999.[1]
It was meant to cross the Atlantic or the Pacific Ocean in half the time of a non-supersonic aircraft. It was also intended to be fuel efficient, carry 300 passengers, and allow customers to buy tickets at a price only slightly higher than those of subsonic aircraft. The goal was to provide sufficient technology for an industry-led product launch decision in 2002, and if a product was launched, a maiden flight within 20 years.[2]
The program was based on the successes and failures of the British/French Concorde and the Russian Tupolev Tu-144, as well as a previous NASA Supersonic Transport (SST) program from the early 1970s (for the latter, see Lockheed L-2000 and Boeing 2707.) While the Concorde and Tu-144 programs both yielded production aircraft, neither was produced in sufficient numbers to pay for their development costs.
