USS Marlin (SST-2), originally USS T-2 (SST-2), was a T-1-class training submarine in commission from 1953 to 1973. She was the second submarine of the United States Navy to be named for the marlin, a large game fish. She was one of the smallest operational submarines ever built for the U.S. Navy.

T-2 was laid down on 1 May 1952 by the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut. She was launched on 14 October 1953, sponsored by Mrs. William R. DeLoach, and commissioned as USS T-2 on 20 November 1953 with Lieutenant Edward Holt in command.

After shakedown in the Massachusetts Bay area, T-2, got underway from New London, Connecticut, in late January 1954 for her home port at Naval Station Key West at Key West, Florida. Assigned to Submarine Squadron 12, Submarine Force, United States Atlantic Fleet, she immediately began operations in the sector from southern Florida to Guantánamo Bay, Cuba. For a decade and a half she performed valuable service as a target and training ship and helped to evaluate submarine and antisubmarine warfare equipment and tactics.
