Number 120 Squadron or No. CXX Squadron is a squadron of the Royal Air Force which was established as a Royal Flying Corps unit late in World War I, disbanded a year after the end of the war, then re-established as a RAF Coastal Command squadron during World War II. Although disbanded again a month after Victory in Europe Day, during and after World War II it operated almost continuously, with maritime patrol aircraft; most recently with the Hawker Siddeley Nimrod, based at RAF Kinloss in Scotland until the type's withdrawal in March 2010. The squadron was disbanded again the following year. No. 120 Squadron stood up again in April 2018 at RAF Lossiemouth and became the first squadron to be equipped with the Boeing Poseidon MRA1 anti-submarine warfare (ASW) aircraft on 31 October 2019. History Formation in First World War 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 No. 120 Squadron spent late 1918 and 1919 flying communication and mail flights in Western Europe until it was disbanded on 21 October 1919. Second World War The squadron reformed as part of Coastal Command in Northern Ireland on 2 June 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 RAF Aldergrove, Northern Ireland and RAF Reykjavik, Iceland. The number of Liberators in September 1942 had increased to six Mark I, two Mark II, and three Mark III. No. 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. No. 120 squadron was very successful in this role, sinking 14 U-boats outright; and was credited with a share in sinking three more, plus eight damaged. This was the highest kill total in Coastal Command, achieved while flying from Northern Ireland, Iceland, and in support of Operation Overlord – the Allied invasion of France in 1944. 12 October 1942 – U-597 sunk by depth charges from Liberator H piloted by Squadron
