August/September Dakota Territory Air Museum P-47 Update

P-47: August/Sept Feature Image
The P-47 is nearing the much anticipated day when it will be flown.


In late August and early September wing root fairings, and final main landing gear preparation were important aspects of the restoration work. The skins for the underside of the fuselage, the ducting covers, and the cowling also received a lot of attention.

Wing and Landing Gear

Most of the work on the wings during this month was related to finalizing the main landing gear installation and fitting the wing root fairings.


On the fuselage, some system connections were finalized this month, but the main focus was on the ducting and outer belly skins underneath the fuselage.


Mike’s work on the cowling is progressing nicely.

A variety of ordnance and delivery techniques were used by P-47 units in the Southwest Pacific. 

Glide bombing

Glide bombing is a tactic that uses a reduced dive angle and power reduction to manage speed and still deliver the ordnance on target.

Experiments with the technique known as glide bombing began when pilots found that dive bombing in a P-47 wasn’t very suitable. The problem with dive bombing was that the Thunderbolt gained too much speed.  The excessive speed meant that the pilot had difficulty concentrating on his target because of= fear of being unable to recover from the 60-degree dive necessary for acceptable accuracy. On aircraft specifically designed for dive bombing, speed is kept under control with dive brakes. In any dive of 60 degrees or steeper with no dive brakes, speed build up became unmanageable in the P-47. Another problem that arose with P-47 dive bombing was also related to the speed issue. At dive speeds over 325 to 350 mph, aileron buffeting occurred when the Thunderbolts carried 1000 wing bombs or 165 gallon wing tanks.1

However, the switch to glide bombing was not without difficulties. The disadvantage of glide bombing is that the aircraft is exposed to enemy ground fire for a longer period than in a steeper dive bombing attack.

According to Colonel Gwen G. Atkinson, commanding officer of the 58th Fighter Group from December 1942 until January 1945, in border to minimize losses to ground fire, it was necessary to begin the glide at no less than 15,000 feet, hold airspeed down to below 325 mph, release the bombs between 7,000 and 5,000 feet, and either head for the deck or recover sharply up and to one side.2

Skip Bombing

Another bombing tactic that was used by Pacific Theater P-47s was skip bombing, where bombs were dropped from tree top or mast head altitude. The pilot would approach in a very shallow dive, keeping the speed at about 370 mph carrying a single 500 pound bomb, and under 325 if loaded with the aileron buffet inducing 1000 lb. bombs or 165 gallon wing tanks. As the P-47 approached the target, all eight 50 caliber guns would be fired, very effectively suppressing ground fire. Leveling off at about 50 feet and releasing the bomb load, the bombs would skip over the ground or water surface, allowing the ordnance to stay low enough to impact the side of a ship or building.

Lieutenant Colonel Willaim Banks (Deputy Commander of the 348th Fighter Group) described a skip bombing attack on shipping in Fighter Combat Tactics in the Southwest Pacific by Ray Merriam. 

“A skip bombing target must be studied whenever possible before the mission, especially against shipping or other targets that may have heavy ack-ack.”

“The attack should be made out of the sun when possible.” 

“When the target is sighted, each flight should pick a definite objective. Troop transports can easily be knocked out by two P-47s making a well-timed attack. Destroyers should be attacked by at least four planes.”3

Lt. Col. Banks goes on to say that the approach should be in a fairly steep dive, leveling out in line abreast formation. Strafing should begin a little out of range to confuse and neutralize the enemy gunners.  The bombs should be released at the pull-up point of the attack run.
