P-800 Oniks

The P-800 Oniks (Russian: П-800 Оникс, lit. 'Onyx'), marketed in export as the Yakhont (Russian: Яхонт; lit. 'ruby'), is a Soviet/Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of the P-80 Zubr. Its GRAU designation is 3M55, the air launched Kh-61 variant was planned but never built. The missile has the NATO codename SS-N-26 "Strobile". Development commenced in 1983, and in the 1990s the anti-ship missile was tested on the Project 1234.7 ship. In 2002 the missile passed the whole range of trials and was commissioned. It is reportedly a replacement for the P-270 Moskit, and possibly also of the P-700 Granit.
