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 Onondaga (WPG-79), a United States Coast Guard cutter, was built by Defoe Boat Works in Bay City, Michigan, commissioned on 11 September 1934. From its commissioning until 1941, Onondaga was stationed at Astoria, Oregon, where she performed important law enforcement duties and rendered much assistance to ships in distress. Each year she patrolled the annual pelagic seal migration to the Pribilof Islands, and she attempted to prevent out of season halibut fishing.

The United States Coast Guard Cutter Fir was the last lighthouse tender built specifically for the United States Lighthouse Service to resupply lighthouses and lightships, and to service buoys. Fir was built by the Moore Drydock Company in Oakland, California in 1939. On 22 March 1939, the U.S. Lighthouse Tender Fir was launched. She was steam driven with twin screws, 175 feet (53 m) in length, had a beam of 32 feet (9.8 m), drew 11 feet 3 inches (3.43 m) of water, and displaced 885 tons. Fir was fitted with a reinforced bow and stern, and an ice-belt at her water-line for icebreaking. She was built with classic lines and her spaces were lavishly appointed with mahogany, teak, and brass. The crew did intricate ropework throughout the ship. The cost to build Fir was approximately US$390,000. Fir's homeport was Seattle, Washington for all but one of her fifty one years of service when she was temporarily assigned to Long Beach, California when USCGC Walnut was decommissioned on 1 July 1982.
The second USS Suwannee and third USS Mayflower was a United States Lighthouse Board, and later United States Lighthouse Service, lighthouse tender transferred to the United States Navy in 1898 for service as an auxiliary cruiser during the Spanish–American War and from 1917 to 1919 for service as a patrol vessel during World War I. She also served the Lighthouse Board and in the Lighthouse Service as USLHT Mayflower from 1897 to 1898, from 1898 to 1917, and from 1919 to 1939, and in the United States Coast Guard as the first USCGC Mayflower (WAGL-236) in 1939 and from 1940 to 1943 and as USCGC Hydrangea (WAGL-236) from 1943 to 1945.

Mine planter and the earlier "torpedo planter" was a term used for mine warfare ships into the early days of World War I. In later terminology, particularly in the United States, a mine planter was a ship specifically designed to install controlled mines or contact mines in coastal fortifications. This type of ship diverged in both function and design from a ship operating as a naval minelayer. Though the vessel may be seagoing it is not designed to lay large numbers of mines in open sea. A mine planter was designed to place controlled minefields in exact locations so that they might be fired individually or as a group from shore when observers noted a target to be at or near a designated mine's position. The terms and types of specialized ship existed from the 1860s where "torpedoes" were made famous in the American Civil War until the demise of large, fixed coastal fortifications brought on by the changes of World War II.

After the war the vessel was transferred to the United States Lighthouse Service for operation as a tender on 28 October 1919 and renamed Shrub. Upon merger of that service with the U.S. Coast Guard the vessel was designated the buoy tender USCGS Shrub until 1947.
