Grom was ordered from the British J. Samuel White shipyard in Cowes and was laid down in 1935. The destroyer was commissioned in 1937. During World War II it was used in support of Allied maritime operations. During her operations in the Norwegian Campaign Grom took part in many naval gunfire support missions. On 4 May 1940 Grom was struck by a bomb from a German plane and sank with a loss of life of 59 sailors. The wreck was never raised and it was not until 1986 that it was explored by divers for the first time)
