Under restoration at Yanks Air Museum with the 10.1 gal. oil tank visible. This P-51A was delivered to the USAAC on 26 Apr 43. It has been painted as 43-6274/AX-H. Powered by an Allison V-1710-81 V-12, this model was an improvement over the P-51 (NA-91) with its V-1710-39 engine. Armament was changed from the long-barrelled 20mm Hispano to four 0.50 in Browning MGs. A contract was placed for 1,200 of which 310 were built, with 50 going to the RAF before production switched to the Merlin-powered P-51B. Under Col. Phil Cochran, the P-51A served as a fighter in 1ACG in the CBI theatre.
