June/July Dakota Territory Air Museum’s P-47 Update

P-47 Razorback
2,360 pounds of engine will be supported by the engine mount.

Update

This month the engine mount was fitted and work continued on the unique radio installation necessitated by the Christmas tree tank field modification. Wing structure was added to the fixture and parts fabrication continued.  We will also examine the missions that were conducted during 42-27609’s time in the Papua New Guinea combat zone.

Engine Mount

An exciting and visible sign of progress is the motor mount attached to the firewall for trial fitting. It is still wrapped in protective plastic foam sheet.

Christmas Tree Tank Radio Relocation

One of the unique features of this Thunderbolt is that it had a field modification by the 5th Air Force to increase range. The modification, called a Christmas tree tank because of its shape, was usually removed by late summer of 1944, but 42-27609 still had the tank.

The 42 gallon tank was placed right behind the pilot and occupied the space where the supercharger oil tank and the communication receiver were originally placed. Consequently, those installations had to be modified to make space available for the new tank.

Without having the original parts to either duplicate or repair and use, it would have been impossible to install this unique modification because engineering drawings aren’t available for this field modification.

We’ll take a look at how the original installation was configured and then show the modifications.

Fabrication and Parts

Wings

Progress continues on both wings. This month, the work was mainly related to the spars.

The Southwest Pacific War, May and June, 1944

Early in the Papua New Guinea campaign, the US and Australian ground forces, the 5th Air Force, and RAAF had defeated the Japanese land attempt to take Port Moresby by attacks on the Kokoda Trail and amphibious landings at Milne Bay. The Kokoda Trail leads over the Owen Stanley Mountains from the northeast coast of Papua.

 In 1943 the Army and its air arm went on the offensive and pushed the Japanese out of most of eastern Papua New Guinea.  In the process, airfields at Dobodura, Finschaven and Nadzab were either captured from the Japanese or built to expand allied operations on the northeast part of Papua New Guinea.

The early air operations for this period were designed to eliminate the Japanese air threat in the area from Wewak to Hollandia in western New Guinea. By March, Hollandia had been reinforced and had 250 Japanese aircraft. About half were combat ready at any one time. Allied air superiority had been attained in the Wewak area after months of pounding the Japanese stronghold with B-25s, A-20s and P-47s.  However, the Japanese were still able to use it as a staging base.1

General Kenney ordered attacks on both Hollandia and Wewak. The attacks in late March eliminated the threat of Japanese air attacks on the coming invasion of the Holandia area and allowed the use of carrier air forces to aid in the invasion.

Sunday April 16, 1944 was a bad day for the 5th Air Force. By this time the Japanese air resistance was eliminated, but weather hazards were not. 130 bombers and 40 fighters set out to attack Tadji in the Hollandia area but bad weather contributed to the loss of 32 crewmen and 31 aircraft.2

42-27609 arrives in the Southwest Pacific

On May 8th , 42-27609 arrived in Townsville, Australia on the carrier CVE 31, USS Prince William.

The 15 Thunderbolts, 17 P-38s, 16 A-20s, and 3 P-61s on the USS Prince William were all unloaded by the end of May 8, 1944 and they would have been readied for combat quickly and flown to Papua New Guinea.

It is interesting to note what missions the 5th Air Force was flying during 42-27609’s combat career. From a publication of the Center for Air Force History,  Kit Carter and Robert Mueller’s, Combat Chronology 1941-1945, I have taken the 5th Air Force’s missions for the dates that our P-47 could have been in combat. 

Note that on 15 June, 1944 the 5th Air Force was incorporated into the Far East Air Force (FEAF). FEAF was formed with jurisdiction over the Fifth and Thirteenth AFs with General Kenney in overall command .

The following list of missions are those that either definitely included P-47s (by naming the type), or possibly included Thunderbolts because either the acronym FB for fighter bombers or fgtrs (fighters) was used. There were other missions in this busy period that only listed HB (heavy bombers) or MD (light bombers) as participating aircraft.  Acronyms, punctuation, abbreviations, and grammatical choices in the listing are those of the original authors. The bolded dates are an addition by me, in the interest of visual clarity.

The mission list for 42-27609’s active period is long, so this month we will list the missions that took place in May and June of 1944. Later updates will have missions from July through September 18, 1944; when 42-27609 was struck from flying status.
