Arrow was active during the Falklands War of 1982, where she provided naval gunfire support (NGFS) and rescued most of the surviving crew from HMS Sheffield.

Alacrity left the channel just before dawn and Arrow was waiting to accompany her back to the Task Force when the Argentine submarine San Luis, captained by Fernando Azcueta, fired two SST-4 torpedoes at a range of 5000 yards.

[5] Arrow remained in Bomb Alley (San Carlos Water anchorage) longer than any other ship while receiving temporary repairs to hull cracks by having Seadart lifting beams welded to her upper decks.

On passage east toward Fitzroy on the night of 5 June Arrow detected an unknown surface target close to the shore and fired three star shells over what turned out to be a UK Landing Craft Mechanised (LCM) which was then escorted to Berkeley Sound.

Much of this had first arisen during the Falklands conflict, when engineers were obliged to weld steel plates and girders to parts of the ship where cracks were opening up in the aluminium superstructure.

In July 1991, Arrow was returning from a deployment to the South Atlantic when it joined a US Coast Guard patrol boat in the Caribbean, and played a major role in an operation which resulted in the seizure of 1,500lbs of smuggled cocaine.

Khaibar remains in service with the Pakistan Navy, who purchased from the United Kingdom Government all six surviving Type 21 frigates of the eight originally built (two were lost in the Falklands).
