And with a better engine, de-Navalised, no self-sealing fuel tanks and cockpit armor either. Should burn like a Zero and arguably only Finnish paint schemes ought to have been allowed, no?
Prior to the diversion the USN striped out the self-sealing fuel tanks, pilot armour plating, landing hook and life raft from Finnish F2A-1 Buffalos, which made the aircraft much lighter and more maneuverable. It had approximately less than 10% more wing loading than a Zero.
They were given the export number Model B-239, were equipped with an export-approved Wright R-1820-G5 nine-cylinder radial engine of 950 hp (708 kW) and after their delivery to Finland, the Finnish Air Force added armored backrests, metric flight instruments, the Finnish Väisälä T.h.m.40 gunsight, and four .50 in (12.7 mm) machine guns.
