With the technology of the Hurricane being at the end of the biplane
combat aircraft era, there was an urgent requirement for a modern
fighter with a capability ahead of the anticipated German fighter
development for the Luftwaffe. The Hawker design team lead by Sydney
Camm created the all-metal stressed skin structure Typhoon powered by
the revolutionary Napier Sabre engine. Whereas the Hurricane had been
developed in peacetime, the Typhoon was designed in wartime, when the
urgency of the programme caused the development of both the airframe and
engine to be accelerated, resulting in teething troubles not being fully
solved when the aircraft entered service with the RAF. The much improved
Tempest used the same engine and basic fuselage with thinner lamina flow
wings, giving improved performance at altitude, and allowing the
destruction of the V1s at low altitude. Both aircraft made a significant
impact on the victory by the Allies in WW2, although their low level
ground attack missions were extremely hazardous, and resulted in high
pilot losses.
