USS Lionfish
Moored at Battleship Cove, USS Lionfish preserves a different experience of naval warfare from the towering surface ships nearby. Its long, low hull belonged to a vessel designed to patrol beneath the water, where concealment, careful observation, and coordination among the crew were essential to survival.

Built in Philadelphia, Lionfish was a Balao-class submarine commissioned on November 1, 1944. After training off New England, it traveled to the Pacific, beginning its first war patrol in Japanese waters on April 1, 1945. Its arrival came during the final months of World War II, but its crew soon encountered the dangers of submarine combat. On April 11, Lionfish evaded two torpedoes fired by an enemy submarine.
Submarine service involved more than attacks on enemy vessels. During its first patrol, Lionfish took aboard survivors of a B-29 bomber from another American submarine and transported them to Saipan. Its second patrol included lifeguard duty off Japan, standing ready to assist downed airmen. These assignments made submarines part of a rescue network as well as a fighting force.
Life aboard required sailors to share confined spaces filled with machinery, controls, weapons, and supplies. Work and rest followed watch schedules, while the crew depended on one another to operate the boat and respond to danger. Beneath the surface, an equipment failure or an approaching enemy could demand immediate, coordinated action.
Lionfish’s service continued after the war through training cruises, NATO exercises, and a later assignment as a reserve training submarine in Providence, Rhode Island. In 1973, it became a permanent memorial at Battleship Cove, preserving both the vessel and a connection to the generations who served aboard submarines.
Along Fall River’s waterfront, Lionfish gives visible form to a service often conducted out of sight. Its preserved hull invites attention to the sailors whose duties carried them below the ocean’s surface, far from home and dependent on the skill of their shipmates.

The Fall River Historical Society Mansion
The granite mansion at 451 Rock Street has occupied two locations and served several purposes during its long history. Built as a private home in 1843, it became associated with the Underground Railroad, underwent relocation and architectural transformation, and eventually became the home of the Fall River Historical Society. The house was originally constructed on […]
The Ship’s Store
Touring the ships at Battleship Cove, it was the ordinary spaces that often made me stop and look more closely. The enormous guns and machinery tell us what these ships were built to do, but places like this tell us what it was like to live aboard one. The ship’s store was a small piece […]
Charles M. Braga Jr. Memorial Bridge
Stretching across the Taunton River between Fall River and Somerset, the Charles M. Braga Jr. Memorial Bridge is one of the most recognizable structures on the city’s waterfront. Its steel framework carries Interstate 195 high above the water, connecting communities across southeastern Massachusetts. Opened in 1966, the bridge became an important part of the region’s […]
