Could industry supply separate RAF and naval aircraft?

Would Britain have enough production capacity for the RAF and Royal Navy to buy different aircraft?

Yes. The services historically bought many distinct types already, with occasional adaptations providing useful commonality.

British industry had enough capacity for the services to buy different aircraft. Naval and RAF orders already supported substantially different types during the interwar period. Hawker designs, including the Osprey and Nimrod, provided occasional commonality. Separate purchasing would continue that established degree of specialisation.
