USS Pike (SS–173), a Porpoise-class submarine in the United States Navy, was laid down on 20 December 1933 by Portsmouth Navy Yard, in Kittery, Maine. She was launched on 12 September 1935, sponsored by Jane Logan Snyder, and commissioned on 2 December 1935. Pike was the first all-welded submarine. The welded hull allowed Pike to submerge to much greater depths than her predecessors and at the same time provided greater protection against depth-charge attacks.

After a shakedown in the Atlantic, Pike departed Newport, Rhode Island on 10 February 1937, and proceeded via the Panama Canal to Naval Station San Diego. In 1937-1938, she participated in maneuvers near Hawaii. Entering Manila Bay on 1 December 1939, she served with Submarine Squadron 5 (SubRon 5) out of Cavite, Philippines, Departing on 20 June 1940, she cruised along the coast of China from Shanghai to Tsingtao, returning to Cavite on 24 August.

In response to the Japanese attack upon Pearl Harbor, she put to sea on 8 December, to guard sea lanes between Manila and Hong Kong.

Pike sailed from Manila on 31 December 1941.

On 1 January 1942 she sighted the hospital ship SS Mactan.

On 10 January she sighted USS Shark (SS-174).

On 12 January she sighted the Japanese minelayer Shirataka. Shirataka was heard "pinging" in the supersonic range.

She moored at Port Darwin, Australia, 24 January 1942.

On her third war patrol from 5 February-28 March, she detected enemy craft off the Alor Islands on 20 and 24 February, and off Lombok Strait on the 28 February 1942.

On her fourth war patrol, she sailed from Fremantle, Western Australia, on 19 April, and patrolled north of the Palau Islands and off Wake Island, before reaching Honolulu on 25 May 1942.

From 30 May – 9 June 1942, she patrolled north of Oahu.

Overhauled at Mare Island Naval Shipyard, California, she guided bombers to Wake Island in December, and escaped a severe depth-charging on 14 January 1943 during an attempted attack off Japan.

Departing Pearl Harbor on 31 March 1943, she fired torpedoes at targets off Truk from 12–14 April, and shelled Satawan Island on the 25th.

Getting under way from Pearl Harbor on 22 July 1943 for her eighth war patrol, Pike sank 2,022-ton Japanese cargo ship Shoju Maru near Marcus Island 5 August.

On 6 August, Pike attacked and damaged a 22,500 ton Kasuga-class aircraft carrier under escort by a Fubuki-class destroyer.

On 22 August, Pike sighted a Japanese convoy consisting of six cargo vessels with a Chidori-class torpedo boat escort. Pike attacked the convoy at night, damaging two ships, one of which was determined to be a 2,500 ton Gosei-class freighter, the other was an unidentified 4,000 ton freighter.

Sailing from Pearl Harbor on 28 September, she arrived at New London, Connecticut, 3 November 1943. During the remainder of World War II, she trained submarine crews at the Naval Submarine Base New London.
