SS-N-26 “Strobile” (P-800 Oniks)/ Yakhont / Yakhont-M / Bastion (launch systems)

The SS-N-26 “Strobile” (P-800 Oniks)/Yakhont/Yakhont-M are Russian anti-ship cruise missiles developed by NPO Mashinostroyenia. There are three known variants of the missile. The ship-launched variant is known as the P-800 Oniks and has been designated the SS-N-26 “Strobile” by NATO. 1 The export variant of the ground-launched version is known as the Yakhont. An air-launched variant was developed in 1999 and is known as the Yakhont-M. A sub-launched version has been proposed and is suspected to be fitted to Yasen-class attack submarines. 2 The Oniks can be ground-launched using two variants of Bastion launch system: the stationary Bastion-S, and the transportable Bastion-P.

SS-N-26 Development

The P-800 Oniks was first developed in 1993 by NPO Mashinostroyenia. In 1999, they developed the ground-launched export version, the Yakhont, and an air-launched version, the Yakhont-M. A sub-launched version has been proposed to be fitted to Yasen-class attack submarines, and the Bastion-P and Bastion-S launch systems have since been developed as well. 3

The Oniks was first deployed in 2002 on Russia’s Nakat-class missile ship. 4 The Bastion missile launch systems were first deployed in 2015 with the Russian Army. 5

In 1988, Russia and India collaborated on a joint venture called Brahmos Aerospace Ltd, which produced the Brahmos missile, a supersonic cruise missile based on the Yakhont. 6

SS-N-26 Specifications

This Oniks/Yakhont/Yakhont-M has a range of 300 km. The ASM variant is 8.3 m long, while the SSM variants are slightly longer at 8.6 m. All variants have a diameter of 670 mm and a launch weight of 3,000 kg. The missiles have both an active and passive inertial navigation system and are equipped with either a 200 kg high explosive or 250 kg semi-armour piercing warhead. 7 The missiles are powered by a solid propellant, ramjet motor. 8 Improvements were made in 2002 in the form of updating the previous terminal seeker with an active radar seeker and imaging infrared seeker 9

SS-N-26 Service History

The Yakhont is believed to have been purchased from Russia by Syria, Indonesia, and Vietnam.

In 2009, Syria purchased 72 coastal defense missiles, along with 36 TEL vehicles and the accompanying equipment for the Bastion system.10 Since 2011, Syria has displayed the missiles and has performed flight tests. In July, 2013, an Israeli airstrike on a Syrian warehouse successfully destroyed a significant number of Syria’s Yakhont missiles, although it is believed that several of those missiles were removed prior to the attack 11

On November 15, 2016, Oniks missiles were launched from an unknown location within Syria using a Bastion land-based coastal missile launcher. The missile targeted Syrian rebel groups. It is unclear whether the missiles were launched by Russian or Syrian forces. 12 It is the first known use of the Oniks in a land-attack mode.

On November 21, 2016, it was reported that Russia deployed two Bastion missile launchers to the Kaliningrad exclave, bordering NATO allies Poland and Lithuania, potentially putting freedom of navigation in the western Baltic Sea at risk. 13
