Sukhoi S-54 Sukhoi S-54 The Sukhoi S-54 was a series of three closely related aircraft proposals; the S-54 trainer aircraft, S-55 light fighter designed for export, and the S-56 carrier-capable light fighter. All members of the family resemble the Sukhoi Su-27 in general form, or the Sukhoi Su-33 more closely, but built around a single example of the Saturn AL-31 engine instead of two, and scaled down accordingly to a smaller layout. The design was offered to several potential customers, including South Africa and India, but was turned down. Development is apparently on hold, awaiting a launch customer. The project traces its
