. ''Batfish'' received the Presidential Unit Citation for her sixth war patrol during which she sank three Japanese submarines in the South China Sea in four days. Following the end of World War II, she was decommissioned on April 6, 1946 and laid up as a training vessel in the Pacific Reserve Fleet. She received a reactivation overhaul in January 1952 before she was recommissioned on March 7, 1952 and assigned to Submarine Division 122 in the United States Atlantic Fleet taking part in training operations in the Caribbean and along the East Coast of the United States.. She was decommissioned for the final time on August 4, 1958 and assigned to the Charleston Group of the Atlantic Reserve Fleet. In the Summer of 1959, she was assigned as a United States Naval Reserve training vessel at New Orleans, Louisiana where she was redesignated as an "auxiliary research submarine" (''AGSS-310''). She continued to serve at New Orleans until she was laid up in the Atlantic Reserve Fleet and her name was struck from the Naval Vessel Registry on November, 1 1969. Following a brief time in the reserve fleet she was donated to the Oklahoma Maritime Advisory Board and moved to Muskogee, Oklahoma and opened in 1973 as a museum ship.

The refit was extended, but finally, on 10 May 1944, ''Batfish'' departed Pearl Harbor for Midway Atoll and additional training. While she was at Midway, Lieutenant Commander John K. "Jake" Fyfe relieved Merrill of command.

, she was nearly run over by a Japanese destroyer and only avoided collision by an emergency dive. Upon closing again, she fired six torpedoes from her bow tubes at a trailing transport, but all missed. ''Batfish'' was forced to dive and maneuver to evade depth charges from the convoy's escorts. On 7 November 1944, she again caught up with the convoy when it anchored in San Fernando Harbor. As she closed the crippled heavy cruiser again, the escorts gave chase and depth-charged her until she retreated. ''Batfish'' had no further opportunities to attack Japanese ships until 14 November 1944. Then, while operating in an attack group with the submarines and , she stalked a convoy of eight ships. After ''Ray'' and ''Raton'' had attacked, ''Batfish'' moved in and fired four torpedoes from her stern tubes that she thought sank a transport and an escort. However, these kills were not later confirmed. Soon thereafter, ''Batfish'' received orders to proceed to Pearl, and she arrived there on 1 December 1944.

Since Japanese convoys dwindled constantly both in size and number by this point in the war due to American advances and faltering Japanese defenses, ''Batfish'' encountered only small and isolated transports, and her attacks on them were cut short either by foul weather or by torpedoes that consistently passed under their targets.

During the patrol, Fyfe noted that ''Batfish'' sighted a significant number of Japanese aircraft, but that they passed her without attempting an attack, a behavior he attributed to what he presumed was the Japanese pilots being more concerned about the large number of American planes also in the area than with ''Batfish''.

The three Japanese submarines' use of radar, which, while helping them locate enemy targets, also made them vulnerable to attack because of ''Batfish''′s capability to detect their radar emissions. There were no survivors from any of the three Japanese submarines. ''Batfish'' had performed the unparalleled feat of sinking three enemy submarines in only four days. She headed for Guam on 16 February 1945 in company with ''Blackfish''. As she pulled alongside the submarine tender in Apra Harbor on 21 February 1945, U.S. Navy photographers greeted the successful "sub killer." She continued on to Hawaii in company with ''Archerfish'' and reached Pearl Harbor on 3 March 1945. She received a Presidential Unit Citation for the patrol.

The Muskogee City-County Trust Port Authority in the meantime donated of prime waterfront real estate for the submarine's berth and a memorial park. The procurement committee of the Oklahoma Submarine Veterans chapter met with the Navy to make preliminary arrangements for the transfer of ''Piranha'', but the Navy refused to hold the submarine unless the committee made a formal application for her with transfer from the Navy being immediate once the donation contract was approved. Since the Arkansas River Navigable Waterway system would not be open for at least a year, the procurement committee would have to incur interim docking charges in the meantime. To avoid this expense, the committee decided to wait and take its chances on another submarine being made available after the waterway opened. In September 1970, the procurement committee inspected ''Batfish'' as a possible alternative to ''Piranha'', both of which by then were in reserve at the Naval Inactive Ship Facility in

. Both submarines had suffered considerable neglect and ''Piranha'' had been almost completely cannibalized for parts, but ''Batfish'' was much cleaner and better outfitted. ''Batfish''s better war record compared to ''Piranha''′s impressed the committee. In 1971, the committee made a formal application to the Navy to acquire ''Batfish''. The Navy made no objection to the last-minute swap, and the donation contract was drawn up on 24 June 1971. John H. Chafee, the

. After a general inspection and clearing of fuel and ballast tanks, ''Batfish'' was sealed up and was ready to tow to the Avondale Shipyard on 1 March 1972. At Avondale, it was found that the four barges were insufficient to reduce the submarine's draft, and a new plan was devised to use six barges, ballasted to the outside and linked together by steel cables. On 13 March, ''Batfish'' was partially secured to the barges by lifting straps, but no cables had been placed to bind them together when the British tanker ''Silverman'' passed through a nearby zone at that afternoon: the resulting wake sank one barge and seriously damaged several others, although ''Batfish'' herself escaped major harm. The flotilla of barges was re-assembled, and by two tugs slowly moved ''Batfish'' upriver at .

''Batfish'' arrived at the Will Brothers Port of Muskogee Terminal on 7 May 1972: this was her temporary home until a wide, long trench could be dug to ''Batfish''′s permanent berthing site. On 4 July 1972, while still at Muskogee Terminal, ''Batfish'' unofficially was opened to the public. Heavy spring rains flooded the Arkansas River on 12 March 1973, which caused ''Batfish'' to strain at her moorings, with fears that she would rip loose and damage the surrounding docks or collide with the new

Flood damage and planned relocation

filling her ballast tanks with water. While the park and grounds remain open for visitors, ''Batfish'' was closed to the public. In November 2021, citing the poor drainage and plans to expand the Port of Muskogee, discussions started to center on relocating ''Batfish'' to Three Forks Harbor in Muskogee along with the museum and its artifacts. A firm plan to relocate the Batfish to Port Muskogee’s Three Forks Harbor, along with the proposed Oklahoma War Memorial and Museum, was announced in March 2025. The $28 million proposal would involve relocating the ship by building two 300-foot boat ramps, trailering the ship to a point a mile up the river, and then loading it on a barge to complete the movement to the new site. $8 million of the cost would be for the Oklahoma War Memorial & Museum, which would be upgraded from the current museum and would include interactive displays and exhibits. However, funding was not yet in place, and would need to come from a variety of sources. In May 2025 the Oklahoma State legislature approved $4 million in funding towards the planned relocation. The Museum moved to a temporary spot inside the Robinson Galley at Three Forks Harbor on July 1, 2025.
