USS Toro (SS-422), a Tench-class submarine, was the only ship of the United States Navy to be named for the toro, a name applied to various fish including the cowfish, the catalufa, and the cavallo. Her keel was laid down on 27 May 1944 at the Portsmouth Navy Yard. She was launched on 23 August 1944 sponsored by Mrs. Alan G. Kirk, and commissioned on 8 December 1944 with Commander James D. Grant in command.

Following her completion on 26 December 1944, Toro participated in training exercises out of Portsmouth, New Hampshire, Newport, Rhode Island, and New London, Connecticut, before arriving at Key West, Florida, on 11 February 1945. She provided services to the Fleet Sonar School, then, on 28 February, departed Key West in company with submarine Bumper (SS-333), bound for the Panama Canal Zone were she underwent a week of intensive training. The two submarines set a westward course for Hawaii on 15 March and arrived at Pearl Harbor on 1 April. Toro conducted training exercises out of that port with Submarine Division 101 until 24 April when she departed Oahu in company with submarine Billfish (SS-286). She arrived at Saipan on 6 May and, after one false start, got underway for her first war patrol on 10 May.

After arriving in her patrol and lifeguard area south of Shikoku and east of Kyūshū on 16 May, she occasionally encountered Japanese planes as she pursued her duties. On 18 May, following a probable periscope sighting, Toro detected a transmission on Japanese submarine radar frequency and attempted to close the contact but was unsuccessful.

As she patrolled Bungo Suido, she was often assigned as lifeguard for air strikes against the Japanese islands. While off Omino Shima before sunrise on 25 May, she received word that a B-29 Superfortress was in trouble. She began the search in state four seas with only fair visibility and, two hours after dawn, homed in by friendly air cover, she rescued two Army aviators who had been floating in their lifejackets for three and one-half hours. Twenty minutes later, she rescued another aviator and then continued her search for additional survivors until late in the day. While patrolling on the surface on the following morning, she made radar contact with a possible target at 2,000 yards (1,800 m). The submarine turned toward the contact and shortly there after a torpedo wake crossed her bow, indicating that an enemy vessel had first located her. Toro dove and had no further contact with the unseen attacker. Toro continued patrols and lifeguard duty in Bungo Suido until 14 June when she set her course for the Mariana Islands. She moored at Apra Harbor five days later.

Following refit by submarine tender Fulton (AS-11), she got underway from Guam on 14 July; paused briefly at Saipan for fuel, water, and the replacement of her torpedoes with Mark 18s; and arrived in her patrol area on 24 July. Late in the day, she was drawn far out of her assigned area in a fruitless search for a downed flier. The departure of Toro’s air cover at 1800 left her in a most dangerous situation due to the expected passage of an American task force on an antishipping sweep. Unable to clear the area in time, Toro made radar contact with the task force at 2055. Despite attempts to establish her identity, Toro was soon the target of two obviously unfriendly American ships which bore down on the submarine at a speed of 22 knots (41 km/h) and bracketed her with gunfire at a distance of 7,400 yards (6,800 m). Toro attempted to establish her identity using a flare, smoke bombs, and sonar, but the ships were still firing when she passed 150 feet (46 m). The beleaguered submarine continued down to 400 feet (120 m) and rigged for depth charges. The surface vessels, thinking that they had sunk a Japanese picket boat, remained in the area for half an hour searching for survivors without discovering that their target had been a friendly submarine. An hour after midnight, Toro surfaced and set her course back to her patrol area.

That morning, she returned to her lifeguard station and, in the afternoon, rescued three British aviators afloat on a raft. She maintained her station for carrier strikes against Japan on 28 July and, shortly after noon on 30 July, received a distress message from an United States Army Air Corps P-51 Mustang plane. After circling his plane over the submarine the pilot parachuted from the crippled aircraft at an altitude of only 800 feet (240 m). Within seven minutes, Toro’s crew brought the aviator on board.

She transferred the rescued British fliers to submarine Gabilan (SS-252) on 1 August. On 5 August, while patrolling her lifeguard area for planes returning from bomber raids on the Japanese islands, Toro sighted dense black smoke on the horizon and, receiving reports of a downed pilot in the area, put on all possible speed to investigate the source of the smoke. Less than 20 minutes later, she picked up an Army aviator afloat in his lifeboat impressively marked by a smoke display. Minutes later, a second Army aviator jumped from his plane nearby, and again Toro had a flier on board within seven minutes of the time his parachute opened.

At mid-month, Japan capitulated. After destroying a number of naval mines south of Honshū, the submarine departed the area on 17 August and proceeded via Guam to Midway Island where she arrived on 27 August.

On 4 September, she departed Midway and proceeded via Pearl Harbor and the Panama Canal to east coast ports. She arrived at Philadelphia, Pennsylvania, on 31 October to prepare for inactivation. In January 1946, rescue ocean tug ATR-67 towed the submarine to New London, where on 7 February 1946, Toro was decommissioned and placed in reserve.

Toro was recommissioned on 13 May 1947, and she reported for duty to Submarine Squadron 2, Atlantic Fleet, on 28 May. She conducted hunter/killer exercises, made a simulated war patrol in the Arctic Sea, and joined fleet tactical exercises in the Mediterranean Sea. On 28 January 1950, she joined Submarine Development Group 2, and her operations helped to refine submarine tactics, weapons, and equipment. She worked in the Atlantic Ocean and Caribbean Sea until July 1952, when she reported to Submarine Squadron 2 at New London and assumed new duties training submariners. During the next ten years, she combined these activities with type training and services to ships and aircraft engaged in antisubmarine warfare exercises. She also participated in Operation "Springboard" and made one Mediterranean cruise. She was redesignated an auxiliary submarine with hull classification symbol AGSS in July 1962 and, on 22 November 1962, as her Navy career drew to its close, she made her 11,000th dive while operating in Long Island Sound.

In February 1963, she was ordered to berth with the Philadelphia Group, Atlantic Reserve Fleet, for demilitarization and non-industrial stripping; on 11 March 1963 she was decommissioned, and on 1 April 1963 her name was struck from the Naval Vessel Register. She was slated to be sunk in an attempt to locate submarine Thresher (SSN-593) but the plan was abandoned, and Toro was later sold and scrapped.

Toro received two battle stars for World War II service.
