P-800 Oniks
Russian supersonic anti-ship cruise missile

The P-800 Oniks (Russian: П-800 Оникс; English: Onyx), marketed in export as the Yakhont (Russian: Яхонт; English: 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.
Operational history
Syria
In 2010 Sergei Prikhodko, senior adviser to the Russian President, has said that Russia intends to deliver P-800 to Syria based on the contracts signed in 2007. Syria received two Bastion missile systems with 36 missiles each (72 in total). The missiles' test was broadcast by Syrian state TV.
In May 2013, Russia continued the contract delivery to the Syrian government supplying missiles with an advanced radar to make them more effective to counter any future foreign military invasion. A warehouse containing the Bastion missiles was destroyed by an Israeli air strike on Latakia on 5 July 2013, but US intelligence analysts believe that some missiles had been removed before the attack.
This brief starts where responsible research should: with the source description of “P-800 Oniks” as russian supersonic anti-ship cruise missile. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as russian supersonic anti-ship cruise missile. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q1475405. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1983, 1234, 2002 and 2010.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
