Oops, sorry, that was for Wildcat. My bad.
Wmaker: Underpowered in the final configuration, yes. You may make the claim that the engine itself was fine (and you'd be able to make that argument) but stick said engine into an airframe and all of a sudden the drag that comes with it, the large frontal surface, etc, means the aircraft doesn't have enough power for its given shape to perform as well as contemporary in-line airframes.
Keep up with me here. You're nitpicking about horsepower and weight. The final configuration was slow. It was obsolete right out of the door. It was recognized that it would have no impact against the US Defense or War effort if they were sold around the world. That's not debatable. It earned export status VERY quickly. No slight against Curtiss for wanting to recoup money on it, but nobody saw it as a major threat to anything else in the US arsenal. Higher, faster, quicker. That was the mantra. The radial Hawk fell short.
