S/L Bty moving to Castle Cary, Somerset, in February 1944, and then to Sturminster Marshall, Dorset, in August. Operation Diver Soon after D Day, the Germans began launching V-1 flying bombs against London by day and night. The AA resources in SE England were strongly reinforced in Operation Diver, the S/L belt being thickened up both to cooperate with RAF Night fighters and to use their S/L Control (SLC or 'Elsie') radar to guide LAA guns. Once 21st Army Group overran the V-1 launching sites in northern France, the Luftwaffe took to air-launching V-1s from bombers over the North Sea, a tactic that resulted in further redeployment of AA Command's resources. 69th S/L Regiment was transferred to 56th Light AA Brigade (an all-S/L formation) in 1 AA Group, later in 9 AA Group, which was created specifically to counter these attacks. 354 S/L Battery was based at Hadleigh, Suffolk from September. The regiment remained stationed along the East Coast in 33rd AA Bde of 5 AA Group during 1945, and was placed in suspended animation at RAF Attlebridge on 15 April 1946. 507 (Independent) Light AA Battery 507 (Independent) LAA Bty remained unregimented under AA Command during 1943. On 4 November the battery's A, B and C troops were ordered to disband (the process being completed by 21 November). However, Battery HQ (BHQ) was mobilised on 14 November and joined 178th Heavy AA Rgt, a composite unit comprising both heavy and light AA batteries serving in the garrison of the Faroe Islands. On 24 January 1944 BHQ took command of 563 LAA Trp (as A Trp) and C Trp of 205 LAA Bty (as B Trp). However, 178th HAA Rgt returned to Kilmarnock in Scotland on 19 March and was disbanded on 17 May, including B Troop of 507 LAA Bty. Some personnel transferred from 178th HAA Rgt to 507 LAA Bty, which was redesignated 507th Composite AA Bty. On 3 April 1945 563 LAA Trp was reconstituted with the assistance of some personnel from the battery, which itself began to disband at the RA Depot, Woolwich, on 8 May 1945, completing the process on 28 May. Postwar When the TA was reconstituted on 1 January 1947, the regiment was reformed as two separate regiments: 604th Searchlight Regiment, RA (The Royal Fusiliers) with HQ at Wembley, and 625th Light Anti-Aircraft Regiment, RA (The Royal Fusiliers) with HQ at Paddington. 604th
