Coast Guard Cutter Fir (WLM 213) underway. Fir is a 225-foot buoy tender homeported in Cordova, Alaska. The Fir’s primary mission is to maintain aids-to-navigation. The ship’s dynamic positioning system allows the buoys to be set in a precise location. Other missions include maritime law enforcement, ports, waterways, and coastal security, search and rescue and environmental protection. U.S. Coast Guard courtesy photo.
