The Sukhoi Su-27K (NATO reporting name: FLANKER-D) is a twin-engine, two-tail, single-seat naval fighter, developed in the late 1970's to address the Yak-38's range and payload shortcomings for planned Soviet CATOBAR aircraft carriers. First flown in 1987, the Su-27K was pursued instead of the Mikoyan MiG-29K for Soviet naval use. The type features a more robust undercarriage, arresting gear, larger folding wings, in-flight refueling probe and more powerful engines to deal with the heavier naval airframe. The type was not introduced until 1998.
The Su-27K is a less expensive Naval anti-ship aircraft option compared to the MiG-29K for PACT decks. The Su-27K features a single P-270 Moskit anti-ship missile, exceptional ECM (50%), six long-range fire-and-forget R-77 Vympel air to air missiles and a 30mm internal GSh-301 cannon. It can be effectively used as an anti-ship aircraft, or as an Air Superiority Fighter to intercept enemy strike aircraft or fighters. The Moskit is extremely accurate and highly powerful. The only major drawback to the Su-27K is that it only carries one ASM. This makes the type excellent for specific target removal of lower-end ships without CIWS, but leaves attacks against command ships relatively ineffective unless multiple Su-27K's, or Su-27K's with other aircraft are sortied as an aerial anti-ship strike package.
