Submarine Specifications

The table below lists the major specifications of all of the submarine classes of the pigboats era. This data was taken from Norman Friedman's U.S. Submarines Through 1945: An Illustrated Design History, Appendix D, pages 306-311, and John D. Alden's The Fleet Submarine in the U.S. Navy: A Design and Construction History. The data represents the configuration of the boat when it was first commissioned into the USN. Subsequent modifications and updates can alter the specifications greatly. Some notes concerning the table are below:

Displ. - Displacement, the amount of water a submarine displaces, analogous to weight.
Surf. Prop. - The number and type of surface propulsion internal combustion engines.
Subm. Prop. - The number and manufacturer of submerged propulsion electrical motors.
Battery Cells - The number represents the number of batteries and the number of cells in each battery.
Kts - Knots, or one nautical mile per hour.
Test Depth - The maximum depth at which the submarine can routinely operate without damage. Most USN submarines have a safety factor of 1.5 built into its design, meaning that the collapse depth of the hull (implosion depth) is 1.5 times test depth.
Tubes (B/S) - The number of torpedo tubes in the bow (B) or stern (S).
Torp Load - The total number of torpedoes carried.
Gun - If present, listed numbers represent bore diameter in inches and the barrel length in calibers.
Crew (O/E) - The crew size, with the numbers representing officers and enlisted.

For the Surfaced Propulsion column, the number of engines, the manufacturer, and the type of engine are listed. If the exact engine model number is known, it is listed as well. Some engines (labled as "Gen") drove only electrical generators. Please note that all submarines after the G-class were equipped with diesel engines. Therefore, the type of engine (i.e. gasoline or diesel) is not listed after that point.
