Russian Black Sea Fleet Bastion Coastal Defense System Launching Oniks Missiles to Ukraine


Video from the Russian Ministry of Defense, reportedly shows the Black Sea Fleet Bastion Coastal Defense System launching Oniks missiles at a Ukrainian command post. Until now, Russia has begun to use some uncommon weapons to hit Ukrainian ground targets. The K-300P Bastion-P (NATO reporting name SS-C-5 Stooge) is a Russian mobile coastal defence missile system. The missile used by the Bastion-P is the P-800 Oniks, a supersonic anti-ship missile with a 200–250 kg (440–550 lb) warhead. The main role of the Bastion-P is to engage surface ships including carrier battle groups, convoys, and landing craft.

The system was developed together with the Belarusian company Tekhnosoyuzproekt. A typical battery is composed of 1-2 command and control vehicles based on the Kamaz 43101 6×6 truck, one support vehicle, four launcher vehicles based on the MZKT-7930 8×8 chassis each operated by a 3-man crew and holding two missiles, and four loader vehicles; launcher vehicles can be located up to 25 km (16 mi) away from the C2 vehicles. Upon halting, missiles can be readied for firing within five minutes, and both fired in 2-5 second intervals. The mobile launcher can remain on active standby over a period of 3–5 days, or up to 30 days when accompanied by a support vehicle.

The P-800 Oniks, also known in export markets as Yakhont is a supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zub. They are fired vertically from the launchers using a solid-fuel rocket booster for initial acceleration, then use a liquid-fuel ramjet for sustained cruising at Mach 2.5. The Oniks maximum range varies at 120–300 km using a low-low or hi-low flight trajectory respectively. Using GLONASS at the initial flight stage and active radar guidance when approaching a target, the missile can fly to an altitude of 14,000 m before descending to sea-skimming altitude of 5 m at the final stage, useful up to sea state 7.

On 2 March 2011, it was reported that Russia would be deploying the system on the Kuril Islands in the Far East. On 15 March 2015, it was reported that Russia had deployed the system in Crimea. On 15 November 2016, Russia announced it had deployed K-300P Bastion-P systems to Syria, where it fired Oniks missiles at land targets as part of the Russian military intervention in Syria, demonstrating a previously undisclosed land attack capability for the coastal defense system; the P-800 uses a combination of autopilot, INS, and a radio altimeter for mid-course guidance and a monopulse dual-mode active/passive seeker for terminal guidance.
