The P-47 could (and did) carry ordnance on the centerline rack.
While they didn't "dive bomb" in the literal sense, they did deliver bombs onto enemy positions from a shallow dive. To what degree on a dive, I am not sure.

I have seen other ordnance in this position too.

I've no idea what the configuration for the tests was, but there was obviously some concern that the propeller might be hit, both from the 8th AF and USN.

Thanks!Nice shot of the paddle blade prop too!
Once the "Jug" has reached it's objective, the drop-tank will have been jettisoned as it would be a huge liability in the event it's struck by ground fire.Of course you're right.
Just going with wing-only bombs on the P-47, plus the drop tank under centreline if dive bomb attack is planned will negate any fear that bomb will hit the prop during the attack. The centreline bomb is also further away from the prop center than it will be the case with a bomb attached to the Corsair's centreline rack.
I have found the relevant page in the 8th AF history.

32 ft/sec/sec is the same regardless of mass, so mass doesn't enter into it.[QUOTE="chuter, ]
Terminal velocity is based on the relationship between mass of object, surface area of object and air density (and temperature, for Mach effects).
This technique appears to be essentially a split-S with bomb release at vertical. .
I did, and still the bomb will meet the propeller in one second.
F4U, specified, limited the dive angle to 60 degrees, see post #8.

If you read carefully all the previous posts, you'll realize that in practical terms the USN, which was then operating primarily F6Fs and F4Us had determined that prop strike was not an issue up to 85 degrees dive angle. We can argue theory till the cows come home, but fact is, they were there, they figured it out, and it worked for them.
I can easily see how a fighter pulling into a 70-80 degree dive from a moderate altitude at low cruise power and <200 KIAS with dive brakes extended would have plenty of time to acquire the target, correct for drift and dive angle, and release the bomb while still accelerating and well before terminal velocity.
From personal experience (unauthorized simulated dive bombing experiments in a T-34 in the days of young and foolish!), I can vouch for the fact that in the dive you're going to be holding a lot of forward pressure on the stick. (Unless you've retrimmed for dive speed, which would make the pullout kind of chancy.) Therefore the moment you relax that pressure the plane is going to snatch itself away from the bomb's trajectory.
I found I could roll in at 10,000 ft, terminal at about 6, (boxy, draggy, crate!), stabilized dive to 4, and consume 3,000 feet in a 3-4 G pullout. If one had a stronger airframe, better G tolerance, and larger gonads, obviously they could accomplish this profile from a lower initial altitude.

Navy taught likewise - in jets - with top hat trim controls - and ejector racks. I wasn't going to risk fumbling around for the manual trim wheel while pulling G at low altitude with no G suit. Nor did I want to be committed to a heavy stick-force pullout while possibly greyed out down low. Besides, I found stick forces were manageable and I could hold my grease pencil "bombsight" steady "on target" with the necessary offsets. Needless to say the "Teenie-Weenie" would not be the weapon of choice against a defended target.Actually the USAF taught running nose down trim on downwind or base for your pass. The reason is at bomb release you want the plane on dive angle, on release speed, at release altitude in trim so there are no adverse forces at pickle. From roll in to pickle is usually a max of five seconds or you are predictable to long for triple A.
