Rising Star (ship, 1991)

Rising Star is a tugboat operated by the United States Air Force to assist cargo vessels supplying Thule Air Base, in northern Greenland. The tugboat is only operated during the period of three months or less that the port is ice-free. For the remainder of the year the vessel is pulled up on the beach. Rising Star is the Air Force's only tugboat.

Built in 1991 at the Swiftships yard in Morgan City, Louisiana, Rising Star is 71 ft long and powered by two two-stroke diesel engines, capable of generating 900 shp each.
