Submarine Classes

Harbor Defense, Coastal Defense, and Concept Development Submarines

What the U.S. Navy wanted in a submarine changed rapidly and often during the 1900-1933 years. These boats filled several different roles while the Navy refined the strategic and tactical concepts of submarine operations. All of these boats contributed something to this effort, although not all were successful.

Later Fleet Submarines

By 1933 the Navy had benefitted from rapidly improving technology and in its own refinement of submarine operational doctrine. The result was the Fleet Submarine era, a fortuitous convergence of events that would greatly contribute to eventual victory in World War II.
