Battleship New Jersey Museum and Memorial, Military museum on Delaware River in Camden, United States.

The Battleship New Jersey Museum and Memorial is a decommissioned US Navy battleship permanently moored on the Delaware River in Camden, New Jersey. The vessel spans multiple decks, with original gun turrets, command spaces, and crew quarters that remain largely as they were during active service.

The New Jersey was commissioned in 1943 and saw service in World War II, the Korean War, the Vietnam War, and operations off Lebanon before its final decommissioning in 1991. It opened as a museum in Camden in 2001, after a sustained campaign by veterans and New Jersey citizens to bring the ship home.

The ship's nickname "Big J" was coined by crew members during its active years and is still used today by visitors and veterans alike. Former sailors regularly return to share their personal stories on board, giving the place a living human dimension that photographs alone cannot convey.

Exploring the full ship requires a reasonable level of mobility, as the stairs are steep and some passageways are narrow. Guided tours are available for those who prefer a structured visit or have difficulty navigating certain areas on their own.

The New Jersey is the most decorated battleship in US Navy history, a record it still holds today. It is also the only battleship to have seen combat during the Vietnam War, firing its main guns at land-based targets.
