The Sukhoi Su-33 (Russian: ????? ??-33; NATO reporting name: Flanker-D) is an all-weather carrier-based twin-engine air superiority fighter designed by Sukhoi and manufactured by Komsomolsk-on-Amur Aircraft Production Association, derived from the Su-27 and initially known as the Su-27K. Compared with the Su-27, the Su-33 has a strengthened undercarriage and structure, folding wings and stabilators, all for carrier operations. The Su-33 has canards, and its wings are larger than the Su-27 for a slower stall speed. The Su-33 has upgraded engines and a twin nose wheel, and is air refuelable.

First used in operations in 1995 aboard the aircraft carrier Admiral Kuznetsov,[N 1] the fighter officially entered service in August 1998, by which time the designation "Su-33" was used. Following the break-up of the Soviet Union and the subsequent downsizing of the Russian Navy, only 24 aircraft were produced. Attempted sales to China and India fell through. With plans to retire the Su-33 once they reach the end of their service life, the Russian Navy ordered the MiG-29K as a replacement in 2009.
