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. This minimizes the yaw movement caused by the recoil of the gun.
