The P-800 Oniks (also known as the SS-N-26 Yakhont) is a supersonic anti-ship cruise missile that entered service in 1999 and is a replacement for the P-270 Moskit (SS-N-22 Sunburn) and, possibly, the P-700 Granit (SS-N-19 Shipwreck) anti-ship cruise missiles. The BrahMos, a joint a supersonic stealth anti-ship cruise missile developed jointly by Russia and India, is also based on the P-800 Oniks. The P-800 is capable of achieving speeds that exceed 2.5 times the speed of sound due to its aerodynamic shape, which makes it nearly impossible to counter. The missile’s detectability is further reduced by the fact that it is covered with radar absorbent material.
