USS Jack (SSN-605)


The USS Jack (SSN-605; submarine, nuclear-powered) was a member of the Permit-class of nuclear attack submarines. It was the second U.S. Navy vessel, and second submarine, to carry the name of a young pike or pickerel.

Her keel was laid on Sept. 16, 1960. She was launched on April 24, 1963 and was commissioned on March 31, 1967, with Commander Louis Urbanczyk Jr. in command.

Though officially part of the Permit class, the Jack was an experimental design. Built with an experimental direct-drive plant with counter-rotating propellers on a single shaft, the Jack was the only member of the class with such an installation. The device had been tried on several other occasions, but its first (and only) attempt in a Permit-class submarine met with disappointment. The Jack’s performance was judged inferior to other members of the class and was 20 feet longer. Due to extensive testing, her commissioning took far longer—nearly four years—to occur than other members of the Permit class.

A member of Submarine Squadron 10 based in New London, Conn., the Jack would perform its duties in the Atlantic and Arctic Oceans and Mediterranean Sea with a minimum of fanfare. One of the rare times it made headlines was in 1981, when she hit the USS Trenton during a sea swell when both vessels were tied up during a port visit to Alexandria, Egypt. Both vessels were lightly damaged.


The Jack was decommissioned and stricken from the Naval Vessel Register on July 11, 1990. The submarine entered the Navy’s Nuclear Powered Ship and Submarine Recycling Program at Bremerton, Wash., and on June 30, 1992, was declared scrapped.
