According to information published by Ukrinform on June 13, 2023, Russia currently has eight combat-ready ships stationed in the Black Sea, including three carriers equipped with Kalibr cruise missiles, carrying a total of 18 Kalibr cruise missiles.

Axar.az reports these missiles are designed to penetrate stationary ground targets' air defences and operate autonomously along predetermined routes. They can adjust their course mid-flight using satellite communication. Unlike ballistic missiles, cruise missiles are known for their accuracy.

The 3M-54 Kalibr missile is a family of Russian cruise missiles that can be launched from ships, submarines, containers, aeroplanes, or transport erector launchers. It has variants designed for anti-ship, anti-submarine, and land attack purposes.
