AA Command was disbanded on 10 March 1955 and there were wholesale mergers amongst its units. Together with 556 (East Lancashire) Heavy AA Rgt (descended from its duplicate 56th (EL) LAA Rgt) 293 (EL) LAA Rgt was merged into 380 (King's Own) Light Regiment (a light field regiment rather than AA), forming P (Church) and Q (Burnley) Btys. When there were further reductions in the TA on 1 May 1961, the King's Own part of the regiment reverted to infantry in the King's Own Royal Regiment (Lancaster), while the two former East Lancs Artillery batteries, P and Q, amalgamated into 288 (2nd West Lancashire) LAA Rgt as Q (East Lancashire) Bty. However, when the TA was reduced into the Territorial and Army Volunteer Reserve (TAVR) in 1967, this regiment also became part of the King's Own, ending the artillery lineage.520–563 Rgts RA at British Army 1945 onwards.372–413 Rgts RA at British Army 1945 onwards.
