P-800

The P-800 Oniks (russian: П-800 Оникс; en, Onyx), also known in export markets as Yakhont (russian: Яхонт; en, ruby), is a Soviet / Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr. Its GRAU designation is 3M55, the air launched Kh-61 variant also exists. The missile has the NATO codename SS-N-26 " Strobile". Development officially started 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.

Description

The missile is carried in flight by aerodynamic lift. The solid-propellant booster is located in the ramjet's combustion chamber and is ejected by the airflow after it has burned out.

Advantages

*Over-the-horizon firing range
*Full autonomy of combat use (" fire and forget")
*A set of flexible ("low-profile sea-skimming", "high-low") trajectories
*High supersonic speed in all phases of flight
*Full harmonization for a wide range of platforms (surface ships, submarines and land-based launchers)
*Possible use of the missile in electronic countermeasures environment and under enemy fire

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.

Oniks missiles were reportedly used in 2016 against ISIL targets.

Russian invasion of Ukraine

In May 2022, Russia’s Defense Minister announced that Russia used high precision Oniks missiles during Russia’s invasion in Ukraine. On 1 May Oniks missiles were used to destroy military equipment near the city of Odesa. There are other reported use of Oniks missiles in Donbas during the same conflict.
