The Su-27, also known as the Sukhoi Su-27, is a twin-engine, supermaneuverable fighter aircraft developed by the Soviet Union in the late 1970s. Designed for air superiority, it features advanced avionics and a high thrust-to-weight ratio, allowing it to perform complex aerial maneuvers. The aircraft is capable of engaging multiple targets and has a range of over 3,500 kilometers. Since its introduction, the Su-27 has been widely exported and has inspired several variants, including the Su-30 and Su-33. It has been used by various air forces around the world and remains a key component of many military aviation fleets today.
