A Russian television host has raged on national television at the Russian Navy for letting the Moskva sink.
Moskva, the Soviet-era flagship of Russia's Black Sea fleet, sank last Thursday after a fire, according to the Russian Defence Ministry.
Ukraine said the fire was caused by its missile strike. Russia said there was a fire from "a detonation of ammunition".
TV host Vladimir Solovyov lashed out on the TV show Russia-1 and criticised the Navy for the sinking of the ship.
"How did you manage to lose it? Explain to me, why the hell you were in that particular area of the Black Sea, at that time?
"I am furious about what happened to the Black Sea Fleet's flagship, Moskva."
The Daily Mail reported Solovyov - commonly known as 'Putin's voice' - was expressing the opinion of the Russian President, who was furious himself with the warship sinking.
If Ukraine's assertion that it hit the ship in a missile strike turns out to be true, the attack will go down in history as one of the highest-profile naval attacks so far this century.
The Moskva would be the biggest Russian warship damaged by enemy fire since 1941, when German dive bombers crippled the Soviet battleship, Marat, in Kronshtadt harbour, military analysts said.
Russia has remained tight-lipped on how many people are missing or dead at sea from the sunken ship.
