A later-generation Wessex analogue cannot be assumed without turbine and engine advances, yet rotorcraft would create an unusually strong demand for power-to-weight improvement. The Wessex's turboshaft engines belong to a separate development path that the counterfactual cannot simply import. Helicopters nevertheless make engine mass and output even more consequential than they are for fixed-wing naval aircraft. The Royal Navy historically pushed for roughly 2,000-horsepower engines after regaining control of the Fleet Air Arm because naval aircraft carried extra fuel, equipment, and survival gear. Sustained Anglo-American rotorcraft competition could therefore redirect more resources toward high-output engines and perhaps bring some useful powerplants forward without guaranteeing a specific postwar design.

Rotorcraft competition accelerates naval engine development
Growing helicopter payload demands could reinforce naval pressure for lighter, more powerful engines throughout the war.
