FIVE aircraft?! Good Grief, I bet the USS Langley had a bigger compliment.
The USS Langley carried 36 aircraft.
5 was the prewar mission package. The "Helicopter carring through deck cruusers, and definitely not aircraft carriers" were intented c.1970 to hunt Soviet subs, North Atlantic, with a force of 9 SeaKing ASW copters ie enough for continous patrol/search/attack.
Late 70s, 5 SeaHarriers were added to chase Bears and Backfires away.
For the Falkland's operation, the carriers went south with 11 Seakings, and 8 SHARs (later increased to 10).
