USS G-2 (SS-27) was a G-class submarine of the United States Navy. While the four G-boats were nominally all of a class, they differed enough in significant details that they are sometimes considered to be four unique boats, each in a class by herself. G-2 was named Tuna when her keel was laid down on 20 October 1909 by the Lake Torpedo Boat Company in Bridgeport, Connecticut, making her the first ship of the United States Navy to be named for the tuna, a large, vigorous, spiny-finned fish highly esteemed for sport and food. She was renamed G-2 on 17 November 1911, launched on 10 January 1912 sponsored by Ms. Marjorie F. Miller, towed to the New York Navy Yard after the termination of the Lake contract on 7 November 1913 where she was completed, and commissioned on 1 December 1913.
USS G-3 (SS-31) was a G-class submarine of the United States Navy. While the four G-boats were nominally all of a class, they differed enough in significant details that they are sometimes considered to be four unique boats, each in a class by herself.

The Lake Torpedo Boat Company of Bridgeport, Connecticut, was an early builder of submarines for the United States Navy in the early 20th century.
The United States Navy's sixteen O-class submarines were created out of the lessons learned from the L class. The O class were about 80 tons larger than the L class, with greater power and endurance for ocean patrols. Due to the American entry into World War I the O class were built much more rapidly than previous classes, and were all commissioned in 1918. O-1 through O-10 were group 1, designed by Electric Boat, O-11 through O-16 were group 2, designed by the Lake Torpedo Boat Company and sometimes considered a separate class. The group 2 boats entered service just before the end of World War I. Eight of the group 1 boats survived to serve in World War II as training boats when they were recommissioned in 1941.
USS Lykens (SP-876/AT-56) was a steam tugboat purchased from the Reading Company by the United States Navy in 1917. Because she was privately built, she was not of a ship class. She was the only U.S. Navy ship of this name.
