Ordered as a follow-on to the NA-57 as a two-seat advanced trainer, the NA-64 P-2/NAA-64 P-2 represented a major structural improvement, with a longer all-metal fuselage replacing the fabric covered fuselage of the NA-57. As well as metal skin replacing the fabric on the fuselage, the fin was changed from having a corrugated skin to being a smooth stressed skin structure and was moved slightly aft, lengthening the rear fuselage while the engine was moved forward to maintain the center of gravity.
