T-1-class submarine
The T-1-class submarines were a pair of submarines designed by the United States Navy and built in the early 1950s for use in training submarine personnel and testing submarine equipment. Both submarines of the class served in these roles for over 19 years.
Design and construction
Except for the first 25 early development pre-World War I submarines, the T-1 class were among the smallest operational submarines ever built for the United States Navy. The first unit was planned under project SCB 68 as an experimental auxiliary submarine with hull number AGSS-570, but instead was built as the training submarine USS T-1 with hull number SST-1. Her sister ship, USS T-2, was planned as SST-2 from the beginning.The T-1 class were built to resemble the 160-ton, 16-crew s, of which over 100 were in service in 1950. It was thought the M class would be effective in restricted waters such as the Baltic Sea and parts of the Mediterranean Sea. The T-1 class were built to train anti-submarine warfare forces in countering small submarines.
Both submarines were constructed by the Electric Boat Division of the General Dynamics Corporation at Groton, Connecticut, in 1952–1953.
