What's the HP rating on that? It just doesn't look right, though.
The P&W radial engines like the one in the P47 had turbosuperchargers and water injection (2,535 horsepower). Some planes designed for shooting down buzz bombs had 2800 h.p. I imagine that today we could come up with something just as good or better.

"Powerplant: 1× Allison XT-40-A-2 turboprop, 5,100 shp (3,800 kW)" And this was in 1950...
The Allison T56 Turboprop used on the C-130, P-3, E-2 and C-2 develops in the neighborhood of 4,000 HP.
T56 weighs just under 2,000 lbs, while the Wright R3350 of the A1 Skyraider produced 2,700 HP while weighing over 2,600 lbs.
