Moskva sink: How course of conflict changes as Russia loses its warship

Moskva was able to provide long-range and mobile air defence protection for the entire Black Sea Fleet and was a floating command and control centre. 

Russia-Ukraine Conflict: Russia has confirmed the Moskva missile cruiser, the flagship of its Black Sea Fleet, has sunk while being towed to port following what it said was a fire and explosions involving ammunition stowed onboard.

Ukraine says the Moskva`s fate was sealed by a missile strike launched by its forces from the coast which ripped open the hulking Soviet-era ship`s hull. Russia`s defence ministry has not confirmed that version of events. Reuters is unable to verify either side`s assertions.

WHAT CAPABILITIES DOES THE SINKING DEPRIVE RUSSIA OF?

Russia has powerful air defence systems deployed in Crimea, which it seized from Ukraine in 2014, but the Moskva was able to provide long-range and mobile air defence protection for the entire Black Sea Fleet and was a floating command and control centre. Its loss degrades the fleet`s air defences, particularly on longer range missions.
