Created during WWII as an official training manual for the Fleet Torpedo School, this whopping 575+ page "pamphlet" contains everything you ever wanted to know about aircraft-launched torpedoes. Within its pages you'll find rare photographs and diagrams as well as informative text. This includes a brief history of the torpedo and a full rundown of the Mark 13, the first American torpedo to be designed solely for aircraft launch (although, they were also used aboard P.T. Boats). Chapters include: exercise heads and attachments, war head and attachments, air flask and midship section, reducing, superheating system and starting gear, propulsion mechanism, depth control mechanism, gyro mechanism including a description of Gyro Mark 12-1, adjustment and tests, and a discussion of loading, air trajectory and stabilizers. Originally restricted, this manual was declassified long ago. This high quality facsimile was created from a rare original. It presents the book in its entirety for the first time in 70 years.
