The four-carrier air groups are bounded by identified sources. A Fleet Air Arm squadron history helps establish which units served where, while Fleet Air Arm Aircraft, Units and Ships 1920 to 1939 indicates the aircraft types and reserve stocks available. Norman Friedman's books on British aircraft carriers and carrier aviation provide wider ship-design and doctrinal context, together with doctoral research into British carrier development. These works constrain the squadron assignments, airframe inventories, and carrier combinations used in the alternate-history order of battle.
