The K-300P Bastion-P (NATO reporting name SS-C-5 Stooge) is a Russian mobile coastal defence missile system. The system was developed together with the Belarus company Tekhnosoyuzproekt.

The main role of the Bastion-P is to engage surface ships including carrier battle groups, convoys, and landing craft. 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 combat duty support vehicle.

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. 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/Yakhont's maximum range varies at 120–300 km (75–186 mi; 65–162 nmi) utilizing a low-low or hi-low flight trajectory respectively. Using satellite guidance at the initial flight stage and active radar guidance when approaching a target, the missile can fly to an altitude of 14,000 m (46,000 ft) 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. The deployment was finally conducted in 2016.
