(SS-138: dp. 854 (surf.), 1,062 (subm.); l. 219'3"; b. 20'8"; dr. 15'11" (mean); s. 14.5 k. (surf.), 11 k. (subm.); cpl. 38; a. 1 4", 4 21" tt.; cl. S-1)

S-33 (SS-138) was laid down on 14 June 1918 by the Union Iron Works, San Francisco, Calif.; launched on 5 December 1918; sponsored by Mrs. Thomas M. Searles; and commissioned on 18 April 1922, Lt. George P. Lamont in command.

Commissioned as crankshaft modifications were ordered for her class, S-33 proceeded from her homeport, San Pedro, to New London, Conn., where she was decommissioned on 15 June and turned over to the prime contractor, the Electric Boat Co., for the alterations. She was recommissioned on 21 December 1922, and assigned, temporarily, to Submarine Division 11 for winter maneuvers. In January 1923, she moved south to the Caribbean. During February, she participated in Fleet Problem I, which tested the defenses of the Panama Canal. Then, in late March, she rejoined the boats of her own division, Division 16, and headed back to San Pedro. The following January, 1924, she returned to the Canal Zone and the Caribbean for further fleet problems and exercises and then operated primarily off southern California into 1926. The previous year, 1925, Division 16 had been transferred to the Asiatic Fleet; and, in November 1926, S-33 moved west to join her sister ships at Cavite. On 22 December, she arrived at that Luzon submarine base and, for the next five years, operated as a unit of the Asiatic Fleet. During the fall and winter months, local exercises and annual overhauls kept her in the Philippines. Each spring she deployed to the China coast for division and fleet exercises out of her summer base at Tsingtao.

In 1932, Division 16 was transferred to Pearl Harbor; and, in May, S-33 retraced her route across the Pacific. She operated in Hawaiian waters for five years. Then, ordered inactivated, she departed Pearl Harbor for the United States east coast on 14 June 1937. Two months later, she arrived at Philadelphia. On 1 December, she was decommissioned and, until 1940, was berthed at League Island.

That summer, increased United States involvement in World War II brought activation orders; and, on 16 October 1940, S-33 was recommissioned. She conducted trials and exercises out of Philadelphia into the spring of 1941. Then, in April, she moved north to New London, the homeport for her division, Submarine Division 52.

The submarine then conducted exercises and patrols off the southern New England coast and out of Bermuda. Toward the end of 1941, however, her operational area was extended, and she moved up to the Newfoundland coast to test S-boat capabilities under high latitude conditions. She returned to New London after the entry of the United States into World War II and, at the end of December 1941, proceeded to Philadelphia for an overhaul. From Philadelphia, she moved south to the Panama Canal Zone and, before the end of May, had conducted two defensive patrols in the western approaches to the canal. In June, she proceeded on to San Diego and, toward the end of the month, moved north to the Aleutians.

S-33 arrived at Dutch Harbor, Unalaska, in early July. On the 7th, she departed on her first offensive war patrol. For the first week, she patrolled in the Adak area, then shifted to the Near Islands. There, off Agattu, fog prevailed from the 15th to the 29th. On the morning of the 30th, visibility increased to about four miles for a few hours but then diminished again. Six days later, the S-boat encountered her first clear day, but fog and mist soon returned. On 7 August, S-33 was ordered back to Dutch Harbor.

On her second Aleutian patrol, 24 August to 26 September, S-33 served as a protective scout during the occupation of Adak. Then, on 2 September, she shifted west to hunt off Kiska. She sighted three enemy ships, but Japanese antisubmarine measures, surface and air, prevented her attacking the first two targets and fog saved the third. Poor visibility, rough seas, and slow speed hindered hunting during her fifth war patrol, conducted in the Kiska area from 15 October to 11 November. Her sixth, 23 November to 9 December in the Attu area, yielded no enemy contacts.

On 11 December, S-33 departed Dutch Harbor for San Diego where she provided services to the West Coast Sound School into February 1943, then underwent overhaul in which she received a fathometer, new radio, radar, keel-mounted sound equipment, and a new distilling unit.

On 18 April, S-33 returned to Dutch Harbor, whence she conducted three more war patrols. Her seventh and eighth patrols were conducted in the Kurils, off Shimu-shu and Paramushiro from 25 April to 22 May and from 4 June to 2 July. Contacts on both patrols were few, and she was able to attack successfully only two; both large fishing sampans which she left burning on 18 June. She conducted her last war patrol, photographic reconnaissance of Buldir and Kiska islands, from 14 July to 9 August, then got underway to return to California.

S-33 arrived at San Diego at the end of August, underwent overhaul, and, then, commenced operations with the West Coast Sound School which were continued until 13 August 1945. Two days later, hostilities ended in the Pacific, and S-33 was ordered to San Francisco for inactivation. She was decommissioned on 23 October 1945 and struck from the Navy list on 1 November. The following year, her hulk was sold for scrapping to the Salco Iron and Metal Co., San Francisco, Calif.

S-55 earned one battle star for her World War II service.
