HMS Alacrity (F174) was a Type 21 frigate of the Royal Navy. She was completed with Exocet launchers in 'B' position.
Alacrity participated in the Falklands War, departing Devonport on 5 April 1982.
The most notable incident involving Alacrity was the sinking of the Argentine supply ship ARA Isla de los Estados over the night of 10-11 May 1982 in the only surface action of the conflict. Alacrity was slightly damaged by an Argentine bomb on 1 May.
As Alacrity exited the Falkland Sound on May 11, the Argentine submarine, ARA San Luis was reported to have fired two torpeados at Alacrity and her sister ship Arrow. Luckily for the British, these missed the ships and both Type 21s rejoined the Task Force.
As with the other surviving Type 21 frigates, Alacrity was suffering from cracking in her hull by the mid-1980s. She was taken in for refitting, with a steel plate being welded down each side of the ship. At the same time modifications were made to reduce hull noise.
Alacrity decommissioned and was transferred to Pakistan on 1 March 1994, being renamed Badr. Exocet was not transferred to Pakistan and Badr had her obsolete Sea Cat launcher removed. A Chinese LY 60N missile launcher was fitted in place of the Exocet launchers. Signaal DA08 air search radar replaced the Type 992 and SRBOC chaff launchers and 20mm and 30mm guns were fitted.
Badr remains in service with the Pakistani Navy.
