The MiG-29K is drastically modified from the Mikoyan MiG-29M for naval operations.
The airframe and undercarriage are reinforced to withstand the stress experienced upon landing.
Folding wings, an arrestor hook, and catapult attachments were added for carrier operations; the aircraft's undercarriage track was also widened.
The MiG-29K, unlike the early MiG-29, can both conduct aerial refueling and "buddy" refuel other aircraft.

The MiG-29K has two widely spaced RD-33MKs.
The early prototypes were fitted with two RD-33K turbofan engines, each with afterburner thrust of 86.3 kN (19,800 lb) and a possible take-off thrust of 92.2 kN (20,723 lbf) for shipborne operations.
The RD-33MK engine features 7% higher power over the base RD-33, enabled by the usage of improved materials for the turbine blades.

Internal fuel was increased from 3,340 to 4,560 kg (7,360 to 10,100 lb), to give a combat radius of 850 km (531 mi).
The combat radius can be increased to 1,300 km (810 mi) with three underwing fuel drop tanks.
The maximum weight of the aircraft grew from 19.5 to 22.4 t (43,000 to 49,400 lb), to allow for increased payloads.
The MiG-29KUB two-seat fighter, intended for pilot training, can also conduct combat missions identical to the single-seat fighter.
