Royal Naval Air Station Machrihanish, (RNAS Machrihanish; or HMS Landrail), is a former Royal Navy air station located near Machrihanish, close to Campbeltown in Argyll and Bute, Scotland. The airfield opened during the Second World War and served at various times as a Fleet Air Arm naval air station, a Royal Air Force facility, and a United States Navy operating base. Part of the site later became the civilian Campbeltown Airport.
Situated to the west of Campbeltown on the western flank of the Kintyre Peninsula, Machrihanish is a former military airbase, recognised for its weather forecasting capabilities. The facility eventually featured an unusually lengthy runway , in addition to a substantial array of technical structures and living quarters.
Machrihanish was established as a naval air station in 1916, operating maritime patrol aircraft and airships until 1918.
The onset of the Second World War prompted the Royal Navy to take control of the original airfield and the surrounding area to the north. Sunley's, a construction firm based in England, initiated the development of a new airfield situated to the north of the existing location, on a flat expanse referred to as The Laggan. Upon its completion, the new airfield was inaugurated as Strabane Naval Air Station and commissioned HMS Landrail on 15 June 1941, subsequently becoming RNAS Machrihanish on 23 June 1941. The original airfield was reclassified as RNAS Campbeltown and commissioned as HMS Landrail II and continued to function as a satellite facility of the newly established airfield.
One of the longer-serving units was 772 Naval Air Squadron, which was based at the airfield from its opening until 1944. The squadron functioned as a Fleet Requirements Unit (FRU), carrying out support tasks such as target towing and later operating the Supermarine Walrus amphibious aircraft for air sea rescue duties.
Another early unit was 790 Naval Air Squadron, an air target towing unit which formed at and operated from Machrihanish for several months from June 1941 before being absorbed by 772 Squadron.
During the war a number of other Fleet Air Arm units made temporary visits, operating aircraft such as the Fairey Swordfish and Fairey Barracuda. Royal Air Force units also used the airfield, including No. 65 Squadron RAF, flying Supermarine Spitfire VB fighters. One of the more permanent residents in the later war years was 740 Naval Air Squadron, which operated communications aircraft at the station between December 1943 and September 1945.
Following the end of the war, flying activity declined and the airfield was placed under care and maintenance in April 1946.
The station was reactivated in December 1951 during the Korean War, once again commissioned as HMS Landrail. During this period 799 Naval Air Squadron operated from the airfield as a refresher flying training unit, flying the Hawker Sea Fury fighter for pilots returning to service after periods in civilian life.
This renewed activity was short-lived, and the squadron departed in September 1952, after which regular military flying ceased once more and the station was again placed under care and maintenance.
In the early 1960s the airfield underwent major redevelopment after being identified for use by NATO forces, particularly the United States Navy. The original Fleet Air Arm four-runway layout was replaced by a single large runway measuring approximately in length.
Thereafter the base developed in relation to NATO requirements during the Cold War, and was the focus of anti-submarine operations with US-controlled nuclear depth charges. A US Navy SEAL unit is also said to have been based here. ã10 million was spent to upgrade the station in the early 1990s, keeping it on a care-and-maintenance basis to provide a runway for emergencies or in the event of conflict. The base remained a UK and NATO military base until 1997.
Between the wars a commercial aerodrome was established and is still operated by the government-owned Highlands and Islands Airports Limited operates with IATA location code "GQJ". It uses the same single runway which, at 3,049m (10,000 feet), is the longest in Scotland. The terminal building are at the south-eastern end. There are scheduled flights to Glasgow.
A number of units were here at some point:
