Submarine Trim and Drain Systems

Originally printed in 1946, The Fleet Type Submarine series of technical manuals remains unparalleled. Contained in its pages and those of the companion texts are descriptions of every operating component aboard a fleet boat. Trim and Drain Systems, Navpers 16166, examines the mechanisms that allow a submarine to be a “submersible ship” -- to dive beneath the waves and resurface. Featuring explanatory text and numerous, detailed diagrams, the book is a wonderful reference for the museum docent, researcher, or anyone who ever wondered “how the heck does that work?” Originally classified “Restricted”, this book was recently declassified and is here reprinted in book form. Some illustrations have been slightly reformatted, and color plates are reproduced in black and white. Care has been taken to preserve the integrity of the text.
