The P-800 Oniks (3M55, Russian: П-800 Оникс, alternatively termed Yakhont (Яхонт) for export markets) is a Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr. Development reportedly started in 1983, and by 2001 allowed the launch of the missile from land, sea, air and submarine. The missile has the NATO reporting codename SS-N-26. It is reportedly a replacement for the P-270 Moskit, but possibly also for the P-750 Granit. The P-800 was reportedly used as the basis for the joint Russian-Indian supersonic missile the PJ-10 BrahMos.
