The Sukhoi Su-33 (Russian: ????? ??-33; NATO reporting name: Flanker-D) is a Soviet/Russian 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.

In 2010, Sukhoi developed an upgraded version of the Su-33; flight trials began in October 2010.[14] This modernized Su-33 was to compete with a potential Chinese indigenous version of the original Su-33, the Shenyang J-15, and to encourage orders from the Russian Navy.[15] Major upgrades to the aircraft included more powerful (132 kN, 29,800 lbf) AL-31-F-M1 engines and a larger weapons carriage; upgrades to the radar and weapons were not possible at the time due to funding constraints.[16] According to military author Richard Fisher, it has been speculated that further modifications to a new production batch would include a phased-array radar, thrust vectoring nozzles, and long-range anti-ship missiles.[16]
To adapt the original Su-27 for naval operations, Sukhoi first incorporated a reinforced structure and undercarriage to withstand the great stress experienced upon landing, particularly quick descents and non-flare landings (landings where the aircraft does not 'float' and slow its descent rate just prior to touchdown).[21] The leading edge slats, flaperons and other control surfaces are enlarged to provide increased lift and manoeuvrability at low speeds, although the wingspan remains unchanged.[22] The wings feature double-slotted flaps and outboard drooping ailerons; in total, the refinements enlarge the wing area by 10–12%.[21] The wings and stabilators are modified for folding to maximise the number of aircraft the carrier can accommodate and to allow ease of movement on deck.[21] The aircraft is outfitted with more powerful turbofan engines to increase thrust-to-weight ratio, as well as an in-flight refuelling probe.[21] The Su-33 sports canards that shorten the take-off distance and improve manoeuvrability, but have required reshaping of the leading edge root extensions (LERX).[22] The rear radome is shortened and reshaped to prevent its striking the deck during high-Alpha (angle of attack) landings.[23]
