Sukhoi-Gulfstream S-21
Sukhoi-Gulfstream S-21 was a conceptual supersonic business jet developed through a collaboration between Russian and American aerospace firms.
In the early 1990s, Gulfstream Aerospace partnered with the Sukhoi Design Bureau to create a supersonic light business aircraft, designated as the S-21. However, skepticism regarding the commercial viability of supersonic passenger travel led to diminishing enthusiasm and increasing project delays.
Eventually, Gulfstream withdrew from the alliance, while Sukhoi continued advancing the S-21 independently.
The aircraft was designed to maintain cruise speeds exceeding Mach 2, with extensive research focused on addressing the complex transonic effects encountered near Mach 1 velocities.
By 2012, no financial support had been allocated for development between 2013 and 2025, suggesting the program had been discontinued.
