The USCG seagoing buoy tender is a type of United States Coast Guard Cutter used to service aids to navigation throughout the waters of the United States and wherever American shipping interests require. The U.S. Coast Guard has maintained a fleet of seagoing buoy tenders dating back to its origins in the U.S. Lighthouse Service (USLHS). These ships originally were designated with the hull classification symbol WAGL, but in 1965 the designation was changed to WLB, which is still used today.
USCGC Sundew (WLB-404) was a 180-foot (55 m) sea going buoy tender (WLB). An Iris, or C-class tender, it was built by Marine Iron and Shipbuilding Corporation in Duluth, Minnesota, United States. Sundew's preliminary design was completed by the United States Lighthouse Service and the final design was produced by Marine Iron and Shipbuilding Corporation in Duluth for the U.S. Coast Guard. On 29 November 1943 the keel was laid. It was launched on 8 February 1944 and commissioned on 24 August 1944. The original cost for the hull and machinery was $861,589.
USCGC Alder (WLB-216) is the final Juniper-class, 225-foot (69 m) seagoing buoy tender of the United States Coast Guard.
The Keeper class of coastal buoy tenders consists of fourteen ships built for and operated by the United States Coast Guard. The ships were launched between 1995 and 1999 and all remain in active service. Their primary mission is to maintain thousands of aids to navigation, both buoys and land-based. Their secondary missions include marine environmental protection, search and rescue, law enforcement, and light ice-breaking.
The USCGC Acacia (WAGL-406/WLB-406) is an Iris-class 180-foot seagoing buoy tender operated by the United States Coast Guard. Acacia was a multi-purpose vessel, nominally a buoy tender, but with equipment and capabilities for ice breaking, search and rescue, fire fighting, logistics, oil spill response, and other tasks as well. She spent almost all of her 62-year Coast Guard career on the Great Lakes. After decommissioning she became a museum ship in Manistee, Michigan.
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.
USCGC Spar (WLB-403) was a 180-foot (55 m) sea going buoy tender. An Iris class vessel, she was built by Marine Ironworks and Shipbuilding Corporation in Duluth, Minnesota. Spar's preliminary design was completed by the United States Lighthouse Service and the final design was produced by Marine Iron and Shipbuilding. On 13 September 1943 the keel was laid, she was launched on 2 November 1943 and commissioned on 12 June 1944. The original cost for the hull and machinery was $865,941.
USCGC Maple (WLB-207) is a Juniper-class seagoing buoy tender operated by the United States Coast Guard. She was based at Sitka, Alaska for 16 years and is currently homeported at Atlantic Beach, North Carolina. Her primary mission is maintaining aids to navigation, but she also supports search and rescue, law enforcement, oil spill response, and other Coast Guard missions.
The U.S. Coast Guard Cutter Oak is a United States Coast Guard seagoing buoy tender; the second of her name and the eleventh of the Juniper class. Home ported in Newport, Rhode Island the "Maine Responder" maintains Aids to Navigation (ATON) along the rugged New England coastline, promoting economic security through navigation safety of the Marine Transportation System. A multi-mission platform, the cutter can also support search & rescue, domestic icebreaking, living marine resources maritime law enforcement, environmental protection, national defense and homeland security missions. The cutter occasionally assists with maintenance support of the National Oceanic and Atmospheric Administration (NOAA) National Data Buoy Center's offshore weather buoys.
USCGC Juniper (WLB-201) is the lead ship of the U.S. Coast Guard's current class of seagoing buoy tenders. She is outfitted with some of the most advanced technological and navigational capabilities currently available.
USCGC Fir (WLB-213) is a Juniper-class cutter of the United States Coast Guard. USCGC Fir is under the Operational Control (OPCON) of the Commander of the Seventeenth Coast Guard District and is homeported in Cordova, Alaska. Fir's primary mission is to service and maintain 132 aids to navigation around the Gulf of Alaska. The buoys USCGC Fir maintains are essential to commercial vessel traffic in major shipping ports of the Prince William Sound such as Valdez, Cordova, as well as across the Gulf of Alaska in Yakutat. USCGC Fir conducts heavy lift aids to navigation operations, law enforcement and other missions as directed.
USCGC Elm (WLB-204) is a U.S. Coast Guard Juniper-class seagoing buoy tender home-ported in Astoria, Oregon. She is responsible for maintaining aids to navigation on the coasts of Oregon and Washington, including the Columbia River.
USCGC Woodrush (WLB-407) was a buoy tender that performed general aids-to-navigation (ATON), search and rescue (SAR), and icebreaking duties for the United States Coast Guard (USCG) from 1944 to 2001 from home ports of Duluth, Minnesota and Sitka, Alaska. She responded from Duluth at full speed through a gale and high seas to the scene of the SS Edmund Fitzgerald sinking in 1975. In 1980, she took part in a rescue rated in the top 10 USCG rescues when she helped to save the passengers and crew of the cruise ship Prinsendam after it caught fire in position 57°38"N 140° 25"W then while being towed sank off Graham Island, British Columbia. She was one of the first vessels to respond to the Exxon Valdez oil spill in 1989. She was decommissioned on 2 March 2001 and sold to the Republic of Ghana to serve in the Ghana Navy.
USCGC Sycamore (WLB-209) is a United States Coast Guard seagoing buoy tender, the second of her name and the ninth of the Juniper-class. She is now home-ported in Newport, Rhode Island, following a one year long Midlife Maintenance Availability (MMA) in Baltimore, Maryland. She was originally home-ported in Cordova, Alaska. Sycamore primarily tends to aids-to-navigation (ATON) in Martha's Vineyard, the Long Island Sound, Hudson River, and New York City Harbor and entrances; however, she is also responsible for maintenance support of National Data Buoy Center's offshore weather buoys. In addition to her primary ATON role, Sycamore also performs other duties, such as, marine environmental protection, maritime law enforcement, domestic icebreaking, search and rescue, and homeland security missions.
USCGC Tupelo WAGL/WLB-303, was a Cactus (A) Class 180-foot buoy tender vessel built by Zenith Dredge Company of Duluth, Minnesota. Her keel was laid 15 August 1942, launched 28 November 1942 and commissioned on 30 August 1943. She was built as a WAGL and redesignated a WLB in 1965.
