Falklands War

During the Falklands War of 1982, Argentine forces occupied the airport. The Argentine Air Force were unable to place their most advanced fighter jets at the base given the relatively short runway, and the risk of attack by the British. However, several air force FMA IA 58 Pucarás with Argentine Navy Aermacchi MB-339 and T-34 Mentor for close air support and air reconnaissance were based at the airport. The Pucarás were deployed against the British land forces, shooting down a Westland Scout and the Aermacchis against the British Fleet.

On 1 May 1982, the Royal Air Force bombed the airport in Operation Black Buck and several other raids were carried out by embarked Harriers. Through the conflict, the airport installations were attacked with 237 bombs, 1,200 shells by deployed Royal Navy ships and 16 missiles. The 42 1,000-lb bombs dropped by the two Black Buck missions left twin strings of craters which are still visible on satellite photos of the airport today.^[2] However, none of these attacks ever put the airfield out of action entirely, and even both Black Buck raids only managed to score one direct hit on the runway, which was repaired sufficiently to allow for C-130 Hercules, Lockheed L-188 Electra and Fokker F-28 transport aircraft to resume night supply flights within 48 hours. These flights continued to bring supplies, weapons, vehicles, and fuel, and airlift out the wounded right until the end of the conflict. The Argentines left the runway covered with piles of earth during the day, in an attempt to mislead the British regarding the condition of the airfield.^[3] In fact, the British were well aware that C-130 flights continued to use the airfield^[4] and attempted to interdict these flights leading to the loss of a C-130 on 1 June,^[5] which was not, however, engaged in any resupply mission.^[6]

During the war the Argentines also heavily mined Yorke Bay to the north of the airport and Surf/Rookery Bays to the southeast with minimum metal mines under the presumption the British would attempt an amphibious landing on the east coast of East Falkland to quickly recapture both the airfield and Stanley in one fell swoop. However, these minefields proved unnecessary when the British opted instead to land at San Carlos on the west coast of East Falkland and attack overland towards Stanley. The beaches surrounding Port Stanley Airport remained heavily mined long after the war as demining had been deemed impractical due to the constantly drifting sand dunes and the disruption that would be done to the breeding colonies of the threatened Magellanic penguin, which continued to thrive on the beaches (being too light to set off the mines). However, the UK eventually commenced these operations in 2009 to comply with the Ottawa Treaty. On November 14, 2020 the island was declared free of landmines.^[7]

Post conflict

After the war, the Royal Air Force took over the airport, renaming it RAF Stanley. Immediately after the conflict air defence of the Islands and garrison was carried out by Sea Harrier FRS.1s and Harrier GR.3s at RAF Stanley and from the aircraft carrier, HMS Invincible, on standing patrol. The runway was extended by to 6,100 feet (1,900 m), paved with aluminium planking, and had arrester equipment installed to allow RAF F-4 Phantom fighters, initially some of those of No. 29 Squadron RAF, to be based on the island as air defence.^[8] The unit was known as "Phandet" until late 1983 when the detachment achieved squadron status following the rundown of No. 23 Squadron RAF in the UK and the resultant transfer of its "nameplate" from RAF Wattisham to the RAF Stanley unit. The Harrier detachment was renamed No. 1453 Flight and remained at RAF Stanley to provide standby air defence, in event of excessive crosswinds, until RAF Mount Pleasant was opened in 1985. In addition, long range Hercules transport aircraft of No. 1312 Flight, resident at RAF Stanley, provided tanker support for the Phantom fighters and transport for local (South Georgia) tasks. The airport was also used by the C-130s of the 'Airbridge' from Ascension Island for trooping and many other essentials until Mount Pleasant became operational.

In 1985, RAF Mount Pleasant opened and in April 1986 Port Stanley Airport returned to civilian use. The temporary aluminium planking runway extension was removed, bringing the runway down to its present length. Although flights from Chile by regional airline Aerovias DAP did use the airport in the early 1990s, for the most part external services have used RAF Mount Pleasant since it opened.^[1]
