Sukhoi 1959, which was over 14 years later. At the start of 1945, the design bureau started working on jet fighters such as the Sukhoi Su-9, Sukhoi Su-11, Sukhoi Su-15, and the Sukhoi Su-17, the Sukhoi Su-10 jet bomber, and the reconnaissance and artillery spotter twinjet, the Sukhoi Su-12. Sukhoi and his team also used the Tupolev Tu-2 bomber to develop and produce the trainer bomber UTB-2, worked on passenger and troop-carrying aircraft, the jet fighter Sukhoi Su-14, and a number of other aircraft. From 1945 to 1950, Sukhoi and his team also developed the Soviet Union's first booster aircraft control
Sukhoi-Gulfstream S-21 speeds. As of 2012, the project had not received any funding for the 2013-2025 development period and appeared to be cancelled. Sukhoi-Gulfstream S-21 Sukhoi-Gulfstream S-21 was a projected Russian-American supersonic business jet. In the early 1990s, Gulfstream Aerospace and the Sukhoi Design Bureau 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 weakened 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
