British racing and Schneider Trophy work demonstrated strong engine design, yet too few aircraft orders had expanded the facilities needed for mass manufacture. The Supermarine Type 322 was directly constrained by Merlin availability, and the Barracuda also needed a sufficiently powerful Merlin after the X engine failed. The central industrial point is that wartime output grows from the factories and skills already present in peace. A small peacetime foundation can expand, but it begins behind demand and cannot instantly supply every new program. For the Barracuda, that delay narrowed the chance of entering service in 1941 with the engine performance its airframe required.

Peacetime production sets the wartime expansion baseline
British engine designers had achieved high power, but limited peacetime output left too small a factory base for rapidly supplying Merlin-powered naval aircraft.
