Rising Star (USAF TG-71-9001) is a tugboat operated by the United States Air Force to assist cargo vessels supplying Thule Air Base, in northern Greenland.

[1][2] The tugboat is only operated during the period of three months or less that the port is ice-free.

[1] Built in 1991 at the Swiftships yard in Morgan City, Louisiana,[1] Rising Star is 71 feet (22 m) long[1] and powered by two two-stroke diesel engines, capable of generating 900 shaft horsepower (670 kW) each.

In the summertime, the 71-foot tugboat escorts fuel tankers and cargo ships, aligns them with the pier, and moves icebergs out of the way as vessels enter North Star Bay.

The tugboat is also used for sightseeing tours of the surrounding bays and fjords during the summer.
