A supersonic transport (SST) is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. The only SSTs to see regular service were Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978, and Concorde's last flight was on November 26, 2003. Following the permanent cessation of flying by all Concorde, there are no SSTs in commercial service.Supersonic airliners' greater speed and efficiency over their conventional counterparts have made them objects of numerous recent and ongoing design studies. Drawbacks and design challenges are excessive noise generation (due to sonic booms), high development costs, expensive construction materials, great weight, and an increased cost per seat over subsonic airliners.Despite these challenges, Concorde was operated profitably in a niche market for over 25 years.
