Russia deployed K-300P Bastion mobile batteries with Yakhont antiship missiles to Crimea

This move is probably to further control and blockade the area following the sinking of decommissioned Russian Navy ships.

The system is designed for the destruction of various surface ships from an enemy's landing squadrons, convoys, carrier strike groups, as well as single vessels and land-based radiocontrast targets in conditions of intensive fire and electronic countermeasures. The system uses the P-800 Yakhont (SS-N-26) anti-ship cruise missile and has a maximum range of 300 km.
Each Bastion system is equipped with 36 cruise missiles as well as truck-mounted radar and other equipment.
