No. 524 Squadron was formed at
RAF Oban,
Argyll and Bute in
Scotland on 20 October 1943 to operate the
Martin PBM Mariner flying boat. The squadron's role was to introduce the Mariner into RAF service. By the end of 1943 the aircraft was ready for operations but the RAF had decided not to operate the type and the squadron was disbanded on either 7 December 1943 or 29 January 1944. The squadron was reformed at
RAF Davidstow Moor on 7 April 1944 to operate the
Vickers Wellington. The squadron carried out night operations of the French coast in preparation for D-Day, mainly attacking E-boats and submarines but also other shipping. It also provided escort to Coastal Command
Beaufighters carrying out night strikes. After the
Normandy Invasion the squadron moved to the east of England to
RAF Docking in a similar role along the Dutch coast. The squadron also directed surface vessels to attack enemy shipping. With the end of the
war approaching the squadron was disbanded on either 25 May 1945 or on 25 June 1945 at
RAF Langham, the appointment of S/Ldr. Willis pointing to the latter. ==Aircraft operated==
