“The engine is mounted slightly transversely in the fuselage, with an 8-degree misalignment from the aircraft’s longitudinal axis.
“The engine exhaust is turned back to the longitudinal axis by a curved composite tailpipe. A composite tailpipe was to help get the gun recoil reaction closer to the aircraft lateral center of gravity (CG) location, the gun is sub-merged as deeply as practical into the right side of the fuselage. Also, the fuselage is not centered about the aircraft centerline, but is offset to the left by three inches. This results in the firing barrel of the gun being only about 18 inches from the lateral CG”
Talk about thinking outside of the box!
"Armament
Guns: 4 × 20 mm (0.79 in) M2 cannon
Other: Up to 8,000 lb (3,600 kg) of ordnance on 15 external hardpoints including bombs, torpedoes, mine dispensers, unguided rockets, and gun pods."
Powerplant: 1 × Wright R-3350-26WA radial engine, 2,700 hp (2,000 kW)
This would need to be replaced by something like the PW100TS, big brother of the venerable PT-6.
