USS Walrus (SS-437), a Tench-class submarine, was the third ship of the United States Navy to be named for the walrus, a gregarious, aquatic mammal found in Arctic waters, related to the seal and a prime source of leather, oil, ivory, and food. Her keel was laid down on 21 June 1945 by the Electric Boat Company at Groton, Connecticut. She was launched on 20 September 1946 sponsored by Miss Winifred P. Nagle. However, work on the submarine was suspended on 7 January 1946 when the contract for her construction was cancelled. Her hull was assigned to the New London Group of the Atlantic Reserve Fleet on 9 December 1952. Her name was struck from the Naval Vessel Register on 9 June 1958.
