CAMDEN, N.J. (AP) — Residents in the Philadelphia area are about to see a rare site — a battleship floating down the Delaware River.

The USS New Jersey is scheduled to move from its dock in Camden on Thursday, when it will head to the Philadelphia Navy Yard for extensive maintenance work. The vessel, guided by tugboats, will initially head to the Paulsboro Marine Terminal, where it will be balanced to prepare for dry docking, and will then go to the Navy Yard six days later.

The maintenance work is expected to take about two months to complete, officials said. Three major repair projects are planned, including repainting the ship’s hull, fixing the anti-corrosion system underneath the ship and inspecting through-hull openings.

The battleship, which was built in the 1940s in Philadelphia, served for about 50 years before its retirement in February 1991. It has been a floating museum since 2011. The ship was built at the former Philadelphia Naval Shipyard and was launched from there on Dec. 7, 1942, the first anniversary of the Japanese air attack on Pearl Harbor.

The ship is the most decorated battleship in Navy history, earning distinction in World War II, the Korean War, the Vietnam War, the Cold War and conflicts in the Middle East, according to its website. The ship steamed more miles, fought in more battles and fired more shells in combat than any other battleship.
