MEMORANDUM

SUBJECT: Industrial Planning Committee - VTB Program; TBU Airplanes, Establishment of Program for.

1. At 1000 on 14 November 1942, a meeting of the Industrial Planning Committee was called for the purpose of initiating an investigation of the circumstances involved in the TBU airplane manufacture, preparatory to the setting up of a definite schedule. Present at the meeting were:

A. F. Bonnalie, Comdr., USNR, representing Production
G. C. Irwin, Jr., Comdr., USNR, representing Production Materials
A, B. Metsger, Lt. Comdr., USN, representing VTB Design
J. D. Clark, Lt., USNR, representing Power Plant Design
W. M. Coy, Lt., USNR, representing Production Schedules
E. F. Zimmerman, Lt., USNR, representing GFE
F. F. Wood, Lt. (jg), USNR, representing GFE
L. E. Thomas, Jr., Lt. (jg) USNR, representing Manufacturing Operations
C. M. Ewing, Ens., USNR, representing Priorities and Allocations

2. It was explained that a long search for a manufacturer competent to handle the production of the TBU airplane had culminated in a decision on Vultee, who would make use of the facilities of the Mack Truck factory in Allentown, which could be made adequate by minor changes. Mr. Brandt of Consolidated Aircraft (the same organization) had announced that Vultee could set up the organization required, and deliver the first airplane in June, 1943, provided the necessary material and GFE were made available. The schedule currently being incorporated in 8-L calls for the first airplane in September of 1943. Vultee's proposed schedule (submitted prior to decision on the Mack plant, and sub-contractor arrangements) is as follows:

to continue at a peak of one hundred forty (140) per month. Present program calls for a total of eleven hundred (1100) of these airplanes.

Vultee is currently reviewing its sub-contractor program, and will shortly offer a revised schedule with only minor differences affected.

3. With this schedule as a background it was proposed that the material and equipment situation be completely surveyed. It was apparent that the following would be necessary:

(a) Assignment of a minimum of the first two hundred (200) airplanes to Group II on the preference list. (Subsequent investigation showed the first thirteen (13) airplanes would automatically be classed as Group I, but the best obtainable for the balance would be Group III).

(b) Provision for materials (principally aluminum in various forms) to fill a pipe-line for production to the extent of the first one hundred eighty-six (106) airplanes.

(c) Acceptance of the R-2800-20 engine (B version) for the first airplanes, until such time as the C engine can be provided. Availability of engines must be investigated.

It was stated that, in all probability, either the 23E50 propeller required by the B engine, or the 33E60 propeller required by the C engine, could be made available. The main question here would be propeller blade forgings which are tight, but which will probably meet the schedule If a Group II classification can be obtained. This was to be Investigated.

4. A preliminary check of GFE indicated that the controlling item was the generator, but a Group II classification would probably take care of the situation.

5. Representatives were urged to obtain any data necessary for a continuation of the discussion on 18 November.
