The Blackburn Roc arrived through the wrong doctrine

Was the Blackburn Roc designed for the Royal Navy's prewar carrier doctrine?

No. It emerged from Air Ministry procurement assumptions, and the Navy quickly judged turret fighters unsuitable for carrier work.

The Blackburn Roc arrived alongside the Skua because the Air Ministry had required a turret fighter. Its procurement followed Air Ministry recommendations while control of naval aviation was changing. The Royal Navy then judged that turret fighters did not suit Fleet Air Arm operations. The requirements behind the purchase conflicted with the Navy's assessment of carrier needs.
