USCGC Spar (WLB-206) is a United States Coast Guard Juniper-class seagoing buoy tender home-ported in Duluth, Minnesota The ship maintains aids to navigation in the Twin Ports and Great Lakes.

Also speaking at her launch ceremony was US Senator Herb Kohl, and US Coast Guard Vice Admiral Timothy Josiah.

In 2007, her area of responsibility extended from Kodiak in the east to Attu in the western Aleutians and north into the Bering Sea, including the Pribilof Islands.

[8] Spar also supports a number of other Coast Guard missions including search and rescue, fisheries law enforcement, light icebreaking, and oil spill response.

[9][10] She cooperates with NOAA to maintain weather buoys in her area of responsibility and to collect hydrographic data to update charts.

Spar was able to secure a tow line on the fishing boat, but it broke in the heavy seas and high winds.

Spar successfully deployed her Vessel of Opportunity Skimming System (VOSS) to practice oil spill recovery.
