Seawolf (SS-197) was laid down on 27 September 1938 by the Portsmouth (N.H.) Navy Yard; launched on 15 August 1939; sponsored by Mrs. Edward C. Kalbfus; and commissioned on 1 December 1939, Lt. Frederick B. Warder in command.

After fitting out, Seawolf departed Portsmouth on 12 April 1940 for her shakedown cruise which lasted until 21 June and took her as far south as the Panama Canal Zone. Seawolf was next assigned to the Pacific Fleet with her home port, San Diego. In the autumn of 1940, she proceeded to Manila Bay and operated from the Cavite Navy Yard. When war with Japan began , the submarine readied for sea and was on her first war patrol from 8 to 26 December 1941.

Seawolf hunted Japanese shipping off San Bernardino Strait. On 14 December 1941, she fired a spread of torpedoes at a tender or supply ship in Port San Vicente with unknown results. She promptly underwent her first depth charge attack but suffered no damage.
