The Jupiter is an American tugboat. It was built in Philadelphia in 1902 by Neafie & Levy for the Standard Oil Company of New York ("Socony"), and was named Socony No. 14. In 1939 it was sold to the Independent Pier Company in Philadelphia, and was renamed Jupiter.
When the USS New Jersey was launched, in December of 1942, Jupiter was one of the tugboats that helped move the massive battleship. Seventy-five years later, Jupiter participated in a ceremony to commemorate the anniversary of the launch (and of the attack on Pearl Harbor a year previously).
