Built in 1937 by the Electric Boat Company at Groton, Connecticut (hull #32) as the Kingston II for in-house use. Her construction was partly intended to train apprentice welders to qualify for work on other construction projects.

In 1946, Electric Boat Company acquired the Canadian aircraft manufacturer Canadair. In 1952, the General Dynamics Corporation was formed to act as a parent company for both subsidiaries.

For 42 years, the tug worked out of the Electric Boat facility, attending to vessel launches, guiding vessels into and out of drydock, and shuttling equipment between adjunct facilities. In addition, she also assisted the nearby community through support of construction projects, firefighting and icebreaking.

By 1980, the size of the vessels being built by Electric Boat began to eclipse the capabilities of the tug, and she was donated to the Mystic Seaport Museum of Mystic, Connecticut.

Since, the tug has served both as a yard craft and as part of the Museum's collection of historic watercraft.
