USCGC Willow was built by the Marinette Marine Corporation in Wisconsin, launched in June 1996 and commissioned in April 1997.[1] She has a length of 225feet, a beam of 46feet, and a draft of 13feet. Willow is propelled by two Caterpillar diesel engines rated at 3,100 horsepower, and has a top speed of 16 knots. She has a single controllable-pitch propeller, which along with bow and stern thrusters, allow the ship to be maneuvered to set buoys close offshore and in restricted waters. A dynamic global positioning system coupled with machinery plant controls and a chart display and information system allow station-keeping of the ship with an accuracy of within five meters of the planned position without human intervention. Willow is also equipped with an oil-skimming system known as the Spilled Oil Recovery System (SORS), which is used in her mission of maritime environmental protection. The cutter has a 2,875 square foot buoy deck area with a crane that is used for servicing large ocean buoys.
USCGC Willow has an area of responsibility within the Seventh Coast Guard District between South Carolina, and the Caribbean Sea. While her primary mission is servicing ATON, she is also tasked with maritime law enforcement, marine pollution prevention and response, treaty enforcement, defense and homeland security, and search and rescue. Willow is also responsible for the periodic servicing of weather buoys operated by the National Data Buoy Center of the National Oceanic and Atmospheric Administration (NOAA).[1] Willow has an icebreaking capability of 14inches at 3 knots and 3feet backing and ramming.
Upon commissioning, Willow conducted the first trans-Atlantic crossing by a U.S. Coast Guard buoy tender in 33 years. On her 68-day voyage she represented the United States in several international festivals and events and made port calls in Ireland, Portugal, France, and Germany. Willow has made a cruise to the Straits of Florida to conduct alien migration interdiction operations.[1] During May 2011, she attended Fleet Week in New York Harbor along with other U.S. Coast Guard cutters.[2] In August 2011, Willow participated in Operation Nanook with Canadian Forces ships,, and . The ten day joint exercise was used to practice search and rescue techniques in an arctic environment as well as exercise arctic sovereignty for the United States and Canada.[3] Willow was the first Coast Guard ATON asset to reach New York City after Hurricane Sandy struck in October 2012. She assisted in the re-opening of New York Harbor by resetting and replacing damaged buoys to mark shipping channels thereby allowing other ships carrying urgently needed gasoline and heating oil safe passage to the harbor.[4]
