Arthur Johns's reference to a carrier's main armament appears to reflect the outgoing Director of Naval Construction more than a settled Royal Navy consensus. Rear Admiral Reginald Henderson, a former carrier commander, had already become Third Sea Lord in 1933. That appointment placed operational aviation experience close to procurement and design decisions. The contrast separates one technical paper's vocabulary from the institution's changing understanding of what made a carrier effective.
