Sukhoi-Gulfstream S-21
Sukhoi-Gulfstream S-21 was an experimental Russian-American supersonic business jet
In the early 1990s, Gulfstream Aerospace and The Sukhoi Design Bureau of Moscow began a joint effort to develop a supersonic small business jet, code named the S-21. Due to questionable market demand for commercial supersonic air travel, commitment to the project wavered and delays mounted.
Gulfstream eventually dissolved the partnership, although Sukhoi continued work on the S-21.
The S-21 would be capable of sustained cruise at Mach 2+ and much R&D has gone into the management of the troublesome sonic shockwave associated with Mach 1+ air speeds.
