What was the first war that the No. 428 Squadron RCAF participated in?
No. 428 Squadron RCAF
In 1954, standing up a 'new Mark IV' fighter squadron, progressing from an initial operating capability, having received its complement of aircrew, to a full operational capability required a change to a Mark III flying and training model.  First, flying practices to confirm that pilot/airborne interceptor integration was retained from No.3 OTU training, and learning the changes in Airborne Interception (AI) and Ground-Controlled Interception (GCI) tactics. The 'Guns Only' Conventional Pursuit Interception (flying Mark IIIs) was replaced with the Lead Collision Course (LCC) Attack (with 2.75-in Folding-Fin Aerial Rockets).[34] The second stage began with a full night flying program, now with lights out interceptions (with fewer visual clues) and 'Bumping Heads'. The third stage of training saw gunnery practice at an air-to-ground range, both the .50 calibre guns and Mighty Mouse rockets at ranges near Winchester, south of Ottawa or Lac St. Pierre, near Sorel, Quebec. Air to Air (Towed) gunnery was practised on a range 'over' Lake Ontario, near RCAF Station Trenton. [35]
