Torpedo launching procedures on U-Boats

In German armed forces (Wehrmacht) there were a whole range of the regulations (Dienstvorschriften). Depending on the forces (army, air force, navy), these regulations were divided into so called H.Dv. (Heer Dienstvorschriften), L.Dv. (Luftwaffe Dienstvorschriften) and M.Dv. (Marine Dienstvorschriften). They contained the field regulations, descriptions of the weapon systems, operating manuals of the communication systems and so on. The set of these regulations can be viewed on this website: http://www.superborg.de/

The text below is the translation of the German torpedo launching procedures - M.Dv.416/3 Torpedo-Schießvorschrift für U-Boote. Here are available the photos of the original document, here is the German version converted into html format.
