The Fleet Type Submarine Online Submarine Trim and Drain Systems
Submarine Trim and Drain Systems, Navpers 16166, is one of a series of
submarine training manuals that was completed
just after WW II. The series describes the peak of WW II US submarine
In this online version of the manual we have
attempted to keep the flavor of the original layout while taking advantage
of the Web's universal accessibility. Different browsers and fonts will cause
the text to move, but the text will remain roughly where it is in the original
manual. In addition to errors we have attempted to preserve from the original (for example, it was H.L. Hunley, not CS Huntley),
this text was captured by optical character recognition. This process creates errors that are compounded while
encoding for the Web. Please report any typos, or particularly annoying layout issues with the Mail Feedback Form for correction.
Our thanks to Shelly Shelstad, creator of History on CD ROM for
permitting us to use images he has scanned, particularly the oversized images that were meticulously pieced together. History on CD
ROM sells a very nice CD or thumb drive version of this manual in PDF format for easy access off the web and for a printing. Thanks also to IKON Office Solutions (now Ricoh USA http://www.ricoh-usa.com) for scanning services.
The Submarine School, Submarine Base, New London, Connecticut and other
activities of Submarines, Atlantic Fleet, have collaborated in the preparation of
this manual. It is designed for use in both instruction and operations.
The text is prepared in two parts: the first three chapters cover the principles
of operation and description of the trim and drain systems; detailed and specific
operational instructions for each system are presented in Chapters 4 and 5. Free
use has been made of sketches and flow diagrams in order to best serve the forces
afloat as well as the students of the Submarine School.
It is recognized that equipment design is subject to change as new requirements are taken into account, and as recommendations from the forces afloat are
acted upon. Consequently, the descriptions and discussions included must be
considered as generally typical rather than final and specific in all details.

Commander Submarines, Atlantic Fleet.
