lurking the coast in order to harass German forces. On 4 May 1940, Grom carried out what turned out to be the last of her many naval gunfire support missions in the Narvik area in the Rombaken fjord. She was attacked by a Heinkel He 111 bomber from Kampfgeschwader 100 (piloted by Lt. Korthals). Grom was hit by two bombs and sank after internal explosion. The wreck was never raised and it was not until 6 October 1986 that it was explored by divers for the first time.
