The Submarine, Navpers 16160-B, is a 1961 revision of the classic WWII submarine training book, The Fleet Type Submarine.
In the post-war period, the United States developed the GUPPY class submarines, and this book uses the USS Becuna (SS-319) to acquaint crews with the design. GUPPY was an extensive conversion program that saw WWII-era boats modified with the snorkel, greater battery capacity, and a more streamlined hull.
The book offers definitions of submarine components and terminology, and provides technical descriptions of various machinery and sub-systems such as the snorkel, ballast tanks, ventilation, trim and steering.
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.
227 pages, 8.5x11", softbound, b&w interior, full color covers.
