The Sukhoi Su-34, also known as the 'Fullback,' is a twin-engine, twin-seat, all-weather supersonic medium-range fighter-bomber developed for the Soviet Air Forces in the 1980s. After being put on hold due to the dissolution of the Soviet Union, the program was revived, and the Su-34 officially entered service in 2014. It has been regarded as one of the most capable warbirds in the Russian Air Force.
Recent reports indicate that Russia has lost a significant number of combat aircraft, including three Su-34 fighter-bombers, in the ongoing conflict in Ukraine. The losses have raised concerns about the sustainability of the Russian air force, especially considering the challenges faced by the country's aerospace industry in producing new aircraft.
