The guided-missile cruiser Moskva, named for the Russian capital, sank while being towed to port after suffering heavy damage.
The Moskva had the capacity to carry 16 long-range cruise missiles.
If Ukraine hit the Moskva with missiles, the cruiser likely represents the largest warship to be sunk in combat since the 1982 Falklands War, which saw a similar-sized cruiser called the ARA General Belgrano torpedoed by a British submarine, killing over 300 sailors on board.
