Her keel was laid down on 4 March 1943 by Electric Boat Co., Groton, Connecticut. She was launched on 14 November 1943 (sponsored by Mrs. M. Comstock), and commissioned on 29 February 1944, Lieutenant Commander (later Rear Admiral) Herman J. Kossler, USN, (class of 1934) in command.
On her maiden patrol Cavalla, en route to her station in the eastern Philippines, made contact with a large Japanese task force on 17 June. Cavalla tracked the force for several hours, relaying information which contributed to the United States victory in the Battle of the Philippine Sea (commonly known as the "Marianas Turkey Shoot") on 19–20 June 1944. On 19 June, she caught the carrier Shōkaku recovering planes, and quickly fired a spread of six torpedoes, with three hits. Shōkaku sank at . After a severe depth charging by three destroyers, Cavalla escaped to continue her patrol, having suffered relatively minor damage by depth charges from the Urakaze. The feat earned her a Presidential Unit Citation.
On 25 November 1944, during her third patrol, Cavalla encountered two Japanese destroyers and made a surface attack which destroyed the Shimotsuki at . The companion destroyer began depth charge attacks, while Cavalla evaded on the surface. Later in the same patrol, on 5 January 1945 Cavalla made a night surface attack on an enemy convoy and sank two converted net tenders (Kanko Maru, Shunsen Maru) at .
Fourth and fifth patrols
Cavalla cruised the South China and Java Seas on her fourth and fifth war patrols. Targets were few and far between, but she came to the aid of an ally on 21 May 1945. A month out on her fifth patrol, the submarine sighted HMS Terrapin, damaged by enemy depth charges and unable to submerge or make full speed. Cavalla stood by the damaged submarine and escorted her on the surface to Fremantle, arriving 27 May 1945.
Cavalla received the cease-fire order of 15 August while lifeguarding off Japan on her sixth war patrol. A few minutes later she was bombed by a Japanese plane that apparently had not yet received the same information or heard the Gyokuon-hōsō radio broadcast. She joined the fleet units entering Tokyo Bay 31 August, remained for the signing of the surrender on 2 September, then departed the next day for New London, arriving 6 October 1945. She was placed out of commission in reserve there 16 March 1946.
Recommissioned 10 April 1951, Cavalla was assigned to Submarine Squadron 8 and engaged in various fleet exercises in the Caribbean and off Nova Scotia. She was placed out of commission 3 September 1952 and entered Electric Boat Co. yard for conversion to a hunter-killer submarine (reclassified SSK-244, 18 February 1953). The SSK conversion included remodeling Cavalla's bow with the addition of a curved housing for a BQR-4 sonar system. The conversion included removal of two bow torpedo tubes, along with remodeling the original conning tower and bridge into the sail visible today.
Cavalla was recommissioned 15 July 1953 and assigned to Submarine Squadron 10. Her new sonar made Cavalla valuable for experimentation, and she was transferred to Submarine Development Group 2 on 1 January 1954, to evaluate new weapons and equipment, and to participate in fleet exercises. She also cruised to European waters several times to take part in NATO exercises, and visited Norfolk, Va., for the International Naval Review (11–12 June 1957). On 15 August 1959, her classification reverted to SS-244.
In November, 1961, Cavalla was ordered to Puerto Rico and provided electrical power via umbilical connection to USS Thresher (SSN-593) which had suffered a diesel generator failure while the nuclear reactor was shut down. Cavalla successfully assisted Thresher's restart of her reactor. Thresher was lost during post-overhaul sea trials on April 10, 1963 during a deep dive.
Cavalla was reclassified an "auxiliary submarine," AGSS-244, in July 1963. Cavalla was decommissioned and struck from the Naval Register on 30 December 1969.
On 21 January 1971, Cavalla was transferred to the Texas Submarine Veterans of World War II. She now resides at Seawolf Park on Pelican Island, just north of Galveston, Texas. Cavalla has undergone an extensive restoration process (see photos, below), and is open for self-guided tours. Among the early benefactors was then President of the Texas United States Submarine Veterans of World War II, Paul Francis Stolpman, and the former Texas secretary of state George Strake, Jr.
