Admiral Ushakov was the lead ship in her class of armoured warships (coastal battleships) of the Imperial Russian Navy, and named after Admiral Fyodor Fyodorovich Ushakov the Russian naval commander of the 18th century.

Journeying via the Suez Canal and across the Indian Ocean, they linked up with Rozhestvensky's fleet off Cam Ranh Bay in Indochina and proceeded together to the Straits of Tsushima.

At the Battle of Tsushima, on 27–28 May 1905, Admiral Ushakov was separated from Nebogatov during the night and fought to the last.

Admiral Ushakov's commanding officer Captain Miklukha refused to surrender and ordered the ship's company to fight.

The ship was sunk within forty minutes and her crew subsequently massacred in the water before the Japanese ceased fire and rescued the remaining survivors.
