Krupp A.G. and Bochumer Verein

Combined Intelligence Objectives Sub-Committee (CIOS) Reports, 1944 – 1945.

Krupps, the giant arms manufacturer based at Essen in the Ruhr, is synonymous with German militarism. This report, one of 700 produced by the CIOS into Germany’s war machine at the conflict’s end, is based on interviews with Krupp executives at their HQ in Essen in April 1945.

This, like most reports, are based on detailed interviews with several German scientists, doctors, technicians, or other officials, and they often incorporate copies of photographs, drawings, and German-language documents. The majority of the reports concern industrial processes and technological developments related to the German war effort. The development and production of aluminium, steel, fuels, ordnance, ammunition, tanks and other vehicles, chemical warfare, optical equipment, and pharmaceuticals all provide examples of these subjects.

Luftwaffe-related topics include aviation medicine, aircraft maintenance, high-speed airplane design and development, and engine design and development. "The German Commercial Air Transport Industry and Related Aeronautical Activities and Developments" constitutes a massive study of the pre-war development of Lufthansa, German airports, and air traffic control, with specialized features on a typical wartime fighter control centre and specific types of large German aircraft.

Most German Navy reports pertain to U-Boats, including studies of the Type XXI submarine, the rotary wing kite used by some U-Boats, submarine pens in France, andsound absorbent coatings for U-Boats.
