MiG-29K has a GSh-30-1 30 mm cannon in the port wing root.
It has provisions for laser-guided and electro-optical bombs, as well as air-to-surface missiles like Kh-25ML/25MP, Kh-29T, Kh-31G/31A, Kh-35U, and rockets.
Kh-31P passive radar seeker missiles are used as anti-radiation missiles.
 Kh-35, Kh-31A antiship missiles are for anti-ship roles; for aerial combat air-to-air missile like RVV-AE, R-27ER/ET and R-73E are fitted.
The aircraft is also adaptable to various foreign weapons.

The MiG-29K has a combination of low-observable technology, advanced electronic-warfare capabilities, reduced ballistic vulnerability, and standoff weapons to enhance the fighter's survivability.
According to Mikoyan, extensive use of radar-absorbent materials reduce the MiG-29K's radar signature 4–5 times over the basic MiG-29.
The RD-33MK turbofan engine was also engineered to reduce infrared signature and improve aircraft camouflage.
