The Spanish Civil War challenged bomber-first assumptions

How did the Spanish Civil War affect Britain's bomber-first assumptions?

It strengthened the case for modern fighters, and Britain was fortunate that racing and private design competition had kept the Spitfire and Hurricane paths alive.

A viewer asks how the Air Ministry reacted when the Spanish Civil War undermined confidence that bombers would always get through. Many RAF, Fleet Air Arm, and Royal Navy personnel would have regarded the evidence as vindication of their earlier warnings. The practical question became whether Britain would now develop a modern high-performance fighter. Schneider Trophy work and competition between Vickers-Supermarine and Hawker had preserved the technical paths that became the Spitfire and Hurricane. Battlefield evidence could therefore be answered by an industrial design base maintained before policy fully changed.
