Enemy resistance in North Africa ceased on 12 May 1943, but AA defence of the Algerian ports continued while they were used to prepare for the invasion of Sicily (Operation Husky). AA engagements were usually against single high-flying reconnaissance aircraft, with one significant raid on the night of 17/18 June. 246 AA Battery was moved to Bône in July, followed in September by RHQ, 'H' (now 40) AAOR and 247 Bty, where the regiment took over operational control of 180 HAA Bty of 64th HAA Rgt, 567 S/L Bty and 124 AA 'Z' Bty. The OC of 398 HAA Bty became AADC of the reduced Philippeville IAZ.
