On 8 June, the ship was alone in Falkland Sound, returning from a naval gunfire mission, when she was attacked by five Dagger fighter-bombers of Grupo 6 of the Argentine Air Force. Despite "Plymouth" firing her 20 mm guns and a Seacat missile, the aircraft dropped eight Mk 82 500 lb bombs, five of which struck home, and fired their 30mm cannons. One Dagger was unable to release its payload due to a mechanical failure, and another suffered light damage from shrapnel. According to other sources "Plymouth" was hit by four 1000 lb bombs. All of the bombs failed to explode, but caused extensive damage: one hit the flight deck, detonating a depth charge and starting a fire, one went straight through her funnel and two more destroyed her Limbo anti-submarine mortar. Internal flooding caused the ship to take a six degree list. Five men were injured in the attack, and were rapidly evacuated by helicopter. The fire took 90 minutes to extinguish with assistance from "Avenger", and repairs were carried out through the night and the next day, restoring some of her capabilities. "Plymouth" then withdrew to a repair area, where naval personnel on board the oil rig support vessel MV "Stena Seaspread" assisted in returning her to fighting order. She returned to shore bombardment duties on 14 June, when Argentine forces in the Falklands finally surrendered.
