Pebble Island lies to the north of West Falkland and in 1982, its 25 inhabitants were mainly involved with tending 25,000 sheep. Its small airstrip was subject to a daring raid by the SAS.
It did have an airstrip, though, or more accurately, four, three of grass, and the other on the beach. On the 24th of April, Naval Air Station Calderon (as it was called) was established there. The sheep shearing sheds and other buildings were taken over and a Skyvan from Stanley Airport was used to bring in personnel and stores.
In what was typical of the period, the naval and air force elements of the Argentine armed forces disagreed with each other so the FAA went to Goose Green and the naval force, stayed at Pebble Island.
Interestingly, they also considered San Carlos as a secondary airstrip location. The airstrip had one runway at 600m long and two at 400m.
To protect the airstrip, 1 Platoon (H Company, 3rd Marine Infantry Battalion), arrived a few days later and the small Falklands Islands Government ship Forrester was used to bring in fuel, ammunition and other supplies. Over the next few days, a squadron of T-34C Mentor’s arrived. In total, there was approximately 150 Argentine personnel at the airstrip.
After the attacks on Goose Green on May 1st, the Air Force Pucara’s were transferred to Pebble Island although a few days later the runway was waterlogged by heavy rain. After a heavy frost on the 7th, the T-34’s conducted an armed recce patrol.
More followed, although poor weather and the conditions of the runway would hamper operations.
This activity and the establishment of Naval Air Station Calderon was not unnoticed by the British forces and so plans were made to deal with it.
D Squadron 22 SAS were to be the means of ‘dealing with it’
After rejecting insertion by Gemini, a combination of Klepper canoes and helicopter were used. An 8 man troop were dropped off at Purvis Bay and paddled to Deep Ferny Valley to lay up and observe the airstrip.
The personnel at observation point crawled forward and noted that there was eleven aircraft present. After some communication problems, the good news was relayed to the waiting force on HMS Hermes.
HMS Hermes was detached along with HMS Glamorgan and HMS Broadsword. The SAS and personnel from 148 (Meiktila) Commando Forward Observation Battery made for a raiding force totalling 45 and were loaded aboard four 846 NAS Sea Kings for the flight into the assembly point at Phillips Cove.
HMS Glamorgan fired on the western edge of the runway to provide a diversion and draw in Argentine forces. Shortly after, the main attack commenced;
Aircraft had cables ripped out and fuel tanks punctured with small arms fire and grenades. It was all over by 03:35 and the SAS teams withdrew to their waiting helicopters, the job well done.
Six Pucara, four T-34C and one Skyvan were damaged or destroyed.
On May 19th, the airstrip was attacked by Harrier and again by three Harrier GR.3’s on the 23rd of May. On the 5th of June, an armed recce sortie discovered what were thought to be two new Pucara’s at Pebble Island, an attack followed. These aircraft were not new and were not serviceable.
By the 23rd, 300m of repaired runway was available.
On the 28th of May, a Twin Otter evacuated wounded personnel and on the 1st of June, two Sea Kings ((2-H-233 and 2-H-234) evacuated other naval personnel back to the mainland.
The airstrip personnel were evacuated to Port Stanley on the 14th of July.
Pebble Island is still used, as is the sand strip at Elephant Beach
