On 2 May 1945, Baya joined the submarine Lagarto in the Gulf of Siam just north of Singapore. The next night, she began tracking a Japanese convoy made up of two gasoline tankers and two escorts. Baya maneuvered into position and fired her bow tubes, but the attack proved unsuccessful. The leading escort, a minelayer, gave chase, but Baya quickly eluded her pursuer. The following day, Baya rendezvoused with Lagarto to plan a coordinated attack on the convoy. The convoy's unusually alert escorts frustrated the efforts of the two submarines, and no opportunities for attack presented themselves that day. Early the next morning Lagarto tried to attack the convoy from a position away from Baya. Afterward, Baya attempted to contact Lagarto but her calls went unanswered. Lagarto was never heard from agan, and Japanese records indicated that the minelayer Japanese minelayer Hatsutaka sank a submarine in that location at that time. Lagarto was lost with all hands. Baya shifted her patrol to the Java Sea, where on 13 May 1945 off Rembang, Java, she attacked a three ship convoy consisting of the tanker Yosei Maru, the tanker Enoshima Maru — which she misidentified as a cargo ship — and an escort bound for Palembang, Sumatra. She chose Yosei Maru as her first target and scored three hits with a spread of six torpedoes. She then aimed her stern tubes at the escort, and believed she scored two hits. To make a clean sweep, she fired her two remaining torpedoes at Enoshima Maru and retired, leaving Yosei Maru sinking and, her crew believed, the other two ships severely damaged. The guard boat No.17 Shonan Maru carried out an unsuccessful counterattack on Baya. Although Baya claimed to have sunk Enoshima Maru, the latter had, in fact, escaped unscathed. On 18 May 1945, Baya reached Fremantle for a refit alongside the submarine tender Clytie.

A fire in the maneuvering room delayed the start of Baya′s fifth war patrol, but after the completion of repairs, she got underway on 20 June 1945. At the beginning of the patrol, she operated south of Cape Selatan in support of Allied landings at Balikpapan, Borneo. On 27 June 1945, she intercepted a single Japanese minelayer but her torpedoes missed. On 29 and 30 June 1945, Baya and the submarine Capitaine conducted a coordinated gun attack on five Japanese small craft. Heavy return fire ended this engagement before Baya could add another sinking to her record. Baya performed lifeguard duties in the Java Sea during the first half of July 1945 and then continued her patrol in that same area. On 16 July 1945, she torpedoed and sank the Japanese Ōtori class torpedo boat Japanese torpedo boat Kari, then en route from Surabaya, Java, to Ambon with two torpedoes; two officers, 22 men, and one civilian passenger who survived Kari′s sinking ultimately reached Masalamo Besar on 18 July. After an unsuccessful gun attack on another Japanese patrol craft, Baya received orders to proceed to Subic Bay on 26 July 1945. She reached Subic Bay on 31 July 1945 and moored alongside Anthedon. She was at Subic Bay when hostilities with Japan ended on 15 August 1945.

Two weeks after Japan's capitulation, Baya departed Subic Bay bound for San Francisco, California, which she reached on 24 September 1945, passing under the Golden Gate Bridge as part of Admiral Halsey's symbolic end of war parade. Shortly thereafter she began inactivation, remaining in the San Francisco area, and on 14 May 1946 she was decommissioned and placed in reserve at Mare Island Navy Yard at Mare Island, California.

Baya was converted to an electronics experimental submarine and recommissioned on 10 February 1948. All torpedo loading and stowage equipment was removed at the Mare Island Naval Shipyard to make room for Naval Electronics Laboratory (NEL) personnel and equipment. Reclassified as an auxiliary research submarine, AGSS 318, on 12 August 1949, Baya conducted experiments for NEL San Diego, California. She participated in local operations near San Diego and served with a joint American Canadian task force gathering scientific data off western Canada in November and December 1948. During July–September 1949 she made a cruise to the Arctic to gather valuable scientific data in the Bering Sea and Chukchi Sea. In April 1953, Baya began an overhaul at the Pearl Harbor Naval Shipyard at Pearl Harbor, Hawaii, and, upon completing it, resumed her duties in support of underwater electronics research, which occupied her throughout 1954 and for most of 1955. Between July and October 1955 she was deployed to Pearl Harbor for further experimental research. In December 1955 she commenced an overhaul at the Hunters Point Naval Shipyard in San Francisco to update her capabilities for NEL testing. Baya was used as a testbed for two early sonar transducer arrays which markedly changed her appearance. The first arrangement of 196 transducers in a 14×14 array was attached to the former gun mount abaft the conning tower, facing starboard and surrounded by a fairwater resembling a second conning tower. She then operated from San Diego and Pearl Harbor for the rest of her career. She conducted a one day cruise to film an episode of the 1958–1961 television show Sea Hunt, starring Lloyd Bridges. After the first array and fairwater were removed, Baya was completely reworked at Mare Island Naval Shipyard during 1958 and 1959 to test a second array, called LORAD (for "LOng RAnge Detection"). The forward torpedo tubes were removed and replaced by a blunt bow containing the forward facing transducer array. A mushroom anchor was installed in the bottom of the hull; and a 23 feet (7 m) section was added between the former forward torpedo room and the forward battery compartment, with quarters for twelve scientists. These modifications increased her overall length to 330 feet (101 m), and her submerged displacement to approximately 2,600 tons. Her maximum speed was reduced to
Baya served in the Vietnam War zone for two months in 1966 in conjunction with sonar research operations for NEL and in submerged visibility studies for the Naval Oceanographic Office. In 1968, she commenced a series of tests for the Operational Test and Evaluation Force, Pacific, and the Naval Undersea Warfare Center. In 1971, she performed research in the Gulf of Alaska before returning to San Diego in December 1971. In April 1972, she made one last cruise to Pearl Harbor to conduct sonar experiments before returning to San Diego.

Baya was decommissioned and struck from the Naval Register on 30 October 1972. She was sold on 12 October 1973 for scrapping.
