How would Britain answer a German Bf 109 carrier fighter?

Would German carrier-based Bf 109s cause Britain to field a modern single-seat carrier fighter earlier?

Probably; Britain would likely accelerate a naval Hurricane, Seafire concept, or comparable fighter rather than accept German superiority.

A carrier-versus-carrier threat changes the urgency of British fighter procurement. If Germany operates a Bf 109 derivative at sea, the Admiralty and cabinet are unlikely to accept a visible fighter disadvantage. Possible answers include reviving the gull-wing naval Spitfire concept, adapting the Hurricane sooner, or pursuing another single-seat solution. Earlier naval fighter work would also affect the carrier force later available in the Mediterranean.
