The Power and the Glory
The SAC Spitfire was stress engineered for at least 1400 horsepower, and 10G
ultimate loads with that much power. The prototypes will use the Allison V-1710 to provide real
V-12 muscle while still keeping the engine cost reasonable. For the purist, SAC is exploring
airframe options to allow an original Rolls-Royce Merlin if you prefer.
