Although Royal Navy doctrine allowed carriers to support anti-submarine hunting groups, it assumed proper escorts and suitable conditions. Henderson's direct knowledge of those criteria makes the historical employment of Courageous in September 1939 unlikely in this scenario. The broader institutional point is that doctrine writers often understand when circumstances justify departing from their own rules, while less experienced officers may apply those rules rigidly or defensively. A carrier could instead reinforce searches for Admiral Graf Spee or German fast battleships, perhaps giving Commodore Harwood air power before the Battle of the River Plate while allowing Ark Royal to work up in safer waters.

Henderson likely prevents Courageous hunting submarines
The officer who wrote carrier doctrine would likely reject its unsafe application and redirect Courageous or Ark Royal toward surface-raider searches.
