The figures used in this report are based on Shipping documents except for charges to the French Forces. The latter charges are explained under the caption "French Forces." Where export figures were not available, it has been assumed, in the absence of repossession reports, that all shipments to port were floated. Repossessions and diversions have been deducted from shipments to port to leave net export figures.
Some items such as certain kinds of vehicles or tools are reported in services or sections other than that of the procuring service, but no effort has been made to cross-reference those items or to arrive at inclusive grand totals because the proportion of such items to the whole report is very small and not statistically significant.
All data in Section I, Chemical, have been taken from "Lend-Lease Transfers--Chemical Warfare Service--Army Service Forces--War Department," published in May 1946. Chemical Warfare Service (now Chemical Corps) is the only service to have issued a report of this kind giving full information on the various stages of lend-lease transfers.
At this writing, the Office of the Chief of Engineers has not yet completed the audit of all lend-lease transfers. However, in order to forestall any significant errors, the Office of the Chief of Finance has examined Engineer shipping documents whenever there was any doubt as to actual quantities exported.
As in other services, certain items did not lend themselves to quantity reporting. So for instance, in the matter of pipes and pipe fittings, a weight estimate used in this report was furnished by the Chief of Engineers.
One very important project not included in the body of the report consists of the Engineer supplies for the Yunan-Burma Railroad. Shipped against this project were ninety-nine line items consisting of tools, machinery, explosives, railroad cars, tracks and general railroad supplies.
This service has been separated along its broad general classifications into three sections; namely, Section III-A, General Supplies; Section III-B, Motor Vehicles; and Section III-C, Ammunition. Each one of these sections, as stated in the Introduction, is further subdivided into categories and groups.
All armament that is standard equipment on aircraft, tanks, self- propelled weapons, and other combat vehicles is included with the planes or vehicles. Such armament is not listed again under specific groups such as Small Arms, Artillery, etc. Separate shipments of armament items for use with planes, tanks, and combat vehicles are included in the Artillery or Small Arms groups.
The categories in this section are not necessarily the ones used by the Office of the Quartermaster General but rather a practical adaptation for the purpose of this report.
This is by far the largest section and one for which a great deal of assistance has been obtained from the technical service. A great number of items are involved, although only a relatively small proportion of them are very important, either in quantity or in value. However, the Important items alone would give a very inadequate picture of Signal Corps transfers. It became necessary, therefore, to list virtually all Signal items, even those of very moderate value and importance.
Some radio equipment installed in airplanes and combat vehicles been listed under Signal items when the equipment was standard on such planes and vehicles.
Because of the technical nature of this service, it is considered [useful] to give a brief description of each of its eighteen categories.
1. Airborne Radio--includes only such radio equipment as is installed and operated in aircraft.
2. Airborne Radar--includes only such radar equipment as is installed and operated in aircraft.
3. Ground Radio--includes air-transportable radio equipment (operated in aircraft), mobile radio equipment (carried in aircraft but not operated in it while in motion), portable radio unit, and fixed radio stations.
4. Ground Radar--includes air-transportable radar equipment (operated in aircraft), mobile radar equipment (carried in aircraft but not operated in it while in motion), portable radar unit, and fixed radar stations.
5. Vehicular Communications Equipment--includes radio equipment installed and operated in vehicles in motion, such as tanks and cars.
6. Wire Communications Equipment--includes telephone and telequipment, telephone and telegraph carrier equipment, public address systems, and high-speed telegraph sending and recording unit.
7. Test and Measuring Equipment--includes military test equipment in general use as well as commercial types of equipment for use in [...]atories or in manufacturing plants.
8. Miscellaneous Power Equipment--includes gasoline or Diesel driven electric generators not included as part of equipments in categories 1 through 5. This category also includes recti[fier] equipment.
9. Radio and Wire Communications Components--This category covers components supplied for the manufacture of radio, telephone, and telegraph equipments as well as materials for the manufacture of components such as vacuum tubes.
10a. Vacuum Tubes--Receiving Type.
10b. Vacuum Tubes--Transmitting Type.
10c. Vacuum Tubes--Special Purpose and Rectifier.
11a. Dry Batteries.
11b. Storage Batteries--This category includes electrolyte for storage batteries shipped dry, the general method of shipment.
12. Wire and Cable--In addition to various types of wire and cable, this category includes reels and other miscellaneous equipments for handling wire and cable.
13. Photographic Equipment--includes cameras and projectors with related equipment, screens, raw films, training films, chemicals, sensitized paper, and miscellaneous photographic supplies.
14. Meteorological Equipment--includes radiosondes, balloons, theodolites, etc.
15. Miscellaneous--This category includes pigeon equipment and supplies, mine detector equipment, and all other items which do not specifically belong in any other category.
Army Air Force Items
The figures for Air items were furnished by the Army Air Forces.
Figures are given only for the major end items--airplanes, by types--and for two major components--airplane engines and propellers. Quantitative information on auxiliary equipment, accessories, spares and components other than engines and propellers, or on ground equipment and supplies for Army Air Forces is not available at this time.
Neither are figures on spare engines and propellers transferred to the French available.
The figures for the British Empire include shipments for the home islands, for all the dominions (except Canada), and for all overseas possessions and colonies. Moreover, certain shipments were made to the United Kingdom for subsequent transfer to other countries, Such as Turkey, Poland, Norway, etc. These shipments have also been included in the figures for the British Empire.
Union of Soviet Socialist Republics
All shipments made on protocol agreements, including pre-protocol shipments which were subsequently made part of the First Protocol, are included in this report.
Figures for the French Forces are a combination of issues per tables of organization and equipment applicable to the French Rearmament Program (First Eight Divisions) and of non-rearmament program shipments.
Inasmuch as it was within the power of the theater commanders to divert commanding general shipments; as shipments for the French Rearmament Program were made to the Commanding General; as the Commanding General to a great extent used his prerogative' to divert such Shipments from the French; and as he in turn furnished to the French large quantities of materials and supplies not originally assigned to them, it was decided to base the charges to the French, as far as the Rearmament Program was concerned, on issues of equipment and supplies, according to tables of organization and equipment, to United States
Army units similar to the French units in the rearmament program. Computations for such issues were made and added to non-rearmament program shipments to arrive at the figures used in this report.
Materiel for the French Forces is still significantly understated because of additional theater transfers which are not included.
Inasmuch as theater and post-VJ transfers are not included in this report, the figures for China are far from representing a complete account of the extent to which this country was benefited by lend-lease matériel, because China, in addition to straight and commanding general shipments, received most of its supplies through theater and post-VJ transfers.
Brazil is the only Latin American country in whose behalf lend-lease shipments were of sufficient importance to warrant their inclusion in Part I, PRINCIPAL COUNTRIES, of this report.
Canada has been treated independently of the British Empire because it has been on the cash reimbursement basis throughout the emergency.
The figures for Turkey do not reflect accurately what the country actually received, because considerable amounts of matériel were assigned to the United Kingdom for retransfer to Turkey. Such assignments are included in figures for the British Empire.
