Fleet, well east of the Falklands during the day, while escorting supply convoys to San Carlos Water or carrying out shore bombardment missions at night. On the night of 13/14 June, Active shelled on Argentine positions during the Battle of Mount Tumbledown. HMS Active took part in five NGS (naval gun supports) at Bluff Cove, Fitzroy, Berkley Sound, Mount Tumbledown, and Port Stanley. By the mid-1980s, in common with the other surviving Type 21s, Active suffered from hull cracking. When the ship was next refitted steel plating was welded along each side of the ship to repair and reinforce the weak points. At the same time modifications were made to reduce hull noise.
