The 3M-24E missile is guided by homing active radar and can carry a warhead to a range of at Mach 0.9 speed. They are powered by two diesel engines.〔(【引用サイトリンク】title=Kora (Type 25A) Class )〕 A HAL Chetak or HAL Dhruv helicopter can operate from the vessel. They also have anti-air shoulder-launched missiles (Strela-2M (Nato code name: SA-N-5 Grail)).The Strela-2M has a range of and a speed of Mach 1.75. INS ''Kulish'' is equipped with two Igla surface-to-air missile launchers. The corvettes are armed with a Ak-176 dual-purpose gun and two AK-630 CIWS. The Ak-176 can fire at the rate of 120 rounds-per-minute (RPM) to a range of , while the AK-630 can fire 3,000RPM to a range of . and are fitted with a Otobreda super rapid gun firing 120RPM.
