Both the F4U and F6F had bigger wings and lower wing loading than the P47 because of the demands of carrier operations and with the same engine and lighter overall weight could lift more. The P47N could lift a lot of weight because of a bigger wing but that wing carried a lot of fuel so the full fuel load could not be carried if a large ordnance load was desired. The F4U was known to have carried a bomb load of 4000 pounds. The standard load with the F4U1D was 2000 pounds.
The F4U was a very good dive bomber, almost as accurate as the SBD. Two reasons were that it was very stable and responsive in a dive and it also had dive brakes. Neither P47 or F6F had this feature. The F4U's dive brakes were the landing gear which could be lowered partially. The F4U could dive bomb at angles up to 85 degrees whereas the SBD was most effective at 70 degrees. The SBD was only about ten per cent more accurate than the F4U. Both were very accurate at release altitudes up to 3000 feet. Bombing on a 25 foot circle, the SBD could expect to get 1.4% direct hits while the F4U could get 1.1% direct hits. Both aircraft exceeded 50% direct hits on 200 foot targets.
