Sukhoi early 1990s, Sukhoi starts to diversify its products and initiated Sukhoi Civil Aircraft to create a line of civil projects for the company. The progress made by the new branch would lead to the development of the utility aircraft, the Su-80, and the agricultural aircraft, the Su-38, less than a decade later. In 1996, the government re-gathered the major part of them forming Sukhoi Aviation Military Industrial Combine (Sukhoi AIMC). In parallel, other entities, including Ulan Ude factory, Tbilisi factory, Belarus and Ukraine factories, established alternate transnational Sukhoi Attack Aircraft (producing e.g. Su-25 TM). The Sukhoi AIMC is composed of
Sukhoi-Gulfstream S-21 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 much research and development has gone into the management of the troublesome transonic effects phenomena associated with near Mach 1 air
