No. 120 Squadron RAF

No. 120 Squadron of the Royal Air Force operated the Nimrod MR2, based at RAF Kinloss, Moray, Scotland until the type's withdrawal in March 2010.

Formation in World War I
No. 120 Squadron of the Royal Flying Corps was formed at Cramlington on 1 January 1918, as a day bomber unit and was planned to be equipped with Airco DH.9. The First World War ended before it became operational, as the DH.9s were not delivered until October 1918, so 120 Squadron spent late 1918 and 1919 flying communication and mail flights in Western Europe until it was disbanded late in 1919.

World War II
Reformed as part of Coastal Command in Northern Ireland in 1941 at RAF Nutts Corner, the unit was equipped with the Consolidated Liberator, flying against the U-Boat threat in the war in the North Atlantic. The squadron received the first Mark I Liberators in June and began flying nine of them in September from bases in Aldergrove, Northern Ireland and Reykjavik, Iceland. The number of Liberators in September 1942 had increased to six Mark I, two Mark II, and three Mark III. 120 Squadron remained the only Coastal Command squadron flying VLR (Very Long Range) Liberators in February 1943 with five Mark I and twelve Mark III.



The squadron was very successful in this role, sinking 14 U-Boats outright, with shares in three more and eight damaged by the end of the war and its disbandment on 4 June 1945 at RAF Ballykelly. This was the highest kill total in Coastal Command, achieved whilst flying from Northern Ireland, Iceland, and in support of Operation Overlord – the Allied invasion of France in 1944.

Immediate Post-War
The squadron reformed again on 1 October 1946, by renumbering 160 Squadron at RAF Leuchars. It was equipped with Lancaster GR.3s though some Liberators remained on strength till June 1947. A detachment moved to Palestine in November 1947 where it carried out searches for illegal immigrant ships until February 1948, when it returned to Britain.

Cold War and beyond
The squadron re-equipped with Shackleton MR.1s in April 1951, and continued operating the MR.2 and MR.3 versions in the maritime patrol role until February 1971. It re-equipped with Hawker-Siddeley Nimrods in February 1971, gaining the updated Nimrod MR.2 in 1981. It flew operationally in the Falklands War in 1982 and the Gulf War in 1991. The squadron has been based at RAF Kinloss since 1 April 1959. On 31 March 2010, the Nimrod MR.2 was withdrawn from service, and the squadron formally disbanded on 26 May 2011.
