Her keel was laid on 25 March 1935 by the Electric Boat Company in Groton, Connecticut. She was launched on 7 July 1936 sponsored by Miss Evelyn Standley, and commissioned on 26 January 1937, Lieutenant Leon J. Huffman in command.
After her shakedown cruise, the new boat conducted training exercises out of New London, Connecticut until getting underway on 26 October 1937 and heading, via Guantánamo Bay, Cuba to transit the Panama Canal on 9 November. Joining the Pacific Fleet, Pickerel operated out of San Diego, California, along the West Coast, and in Hawaiian waters. Subsequently transferred to the Asiatic Fleet, she prepared for war with a vigorous training schedule in the Philippines.
World War II
Upon receiving word of Japan's attack on Pearl Harbor, Pickerel - commanded by Lieutenant Commander Barton E. Bacon, Jr. - sped to the coast of French Indochina and conducted her first war patrol off Cam Ranh Bay and Tourane Harbor. She tracked a Japanese submarine and a destroyer but lost them in haze and rain squalls before they came in torpedo range. On 19 December, she also missed a small Japanese patrol craft with five torpedoes, before returning to Manila Bay on 29 December.
On her second patrol - from 31 December 1941-29 January 1942 - conducted between Manila and Surabaya, the submarine sank Kanko Maru on 10 January 1942. On her third war patrol - from 7 February-19 March - along the Malay Barrier and her fourth - from 15 April-6 June - in the Philippines, she failed to score (although she did make an unsuccessful torpedo attack on the unarmed Japanese hospital ship Takasago Maru on 26 April). 
Pickerel 's fifth war patrol, from 10 July to 26 August, was a voyage from Brisbane, Australia, to Pearl Harbor for refit, with a short patrol in the Mariana Islands en route, during which she damaged a freighter.
She departed Pearl Harbor on 18 March 1943 and, after topping off with fuel and provisions at Midway Island on 22 March, headed for the eastern coast of northern Honshū, Japan and was never heard from again. Pickerel was the first submarine to be lost in the Central Pacific area. She was stricken from the Naval Vessel Register on 19 August 1943.
Post-war analysis of Japanese records give conflicting suggestions about Pickerel 's fate. The Japanese officially credit her with sinking Submarine Chaser Number 13 on 3 April and Fukuei Maru on 7 April, and give no official report of her destruction. Those records also describe an action off Shiramuka Lighthouse on northern Honshū on 3 April 1943 in which naval aircraft first bombed an unidentified submarine, then directed Shiragami and Bunzan Maru to the spot, where they dropped twenty-six depth charges. A large quantity of oil floated to the surface, which was often enough for Japanese ASW ships to believe their target was sunk. It is likely Pickerel 's fuel oil bunkers leaked. Since there were several other ASW operations in the area in that period, and Pickerel was the only American submarine in that area; one of these other attacks, sometime after 7 April, probably claimed her.
