about intelligence manuals
|
The United States Navy Department and War Department produced hundreds of different manuals during World War Two covering the ships, aircraft, vehicles, weapon systems, organization, and activities of the US, allied, enemy, and neutral forces.
In some cases, the Navy and War Departments each produced manuals covering the same topic; in other cases they cooperated to produce a single joint manual on a given topic; and in many cases they did some combination of both - producing a Navy Department manual, a War Department manual, and a Joint Army/Navy manual all on the same topic.
In each case, the manual would have a specific purpose, target audience, level of detail, and classification level. In addition, completely new or supplemental manuals would be produced on the same topics as new information became available. As an example, between 1941 and 1945 the Navy Department produced at least six manuals on Japanese warships, four manuals on Japanese Merchant ships, and two manuals on Japanese aircraft. In addition, the War Department produced at least one Japanese warship manual and two Japanese aircraft manuals. Finally, the War and Navy departments produced two joint manuals that included Japanese warships and at least four joint manuals that included Japanese Aircraft. All told, there were at least 21 manuals or supplements were produced during the war years that described Japanese aircraft, warships, and merchant ships.
In general, War Department manuals would have information geared toward use by ground or airborne personnel. Click here for details on Military Intelligence manuals.
