USCG seagoing buoy tender
Template:More citations needed
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.
Ex U.S. Army mine planters
Six U.S. Army mine planters built 1917–1919 were transferred to the U.S. Light House Service during a reduction in the Army in the early 1920s. These, after absorption into the U.S. Coast Guard, became that service's "Speedwell class":Template:Sfn

The ships were Template:Convert in length, Template:Convert beam with Template:Convert draft displacing 1,130 tons.Template:Sfn Early mine planters, at first termed "torpedo planters," had been modeled after USLHS vessels which had similar requirements for handling heavy loads alongside the vessels so that mine planters were easily converted to buoy work.Template:Sfn
Ex U.S. Army Chimo-class 188' mine planters 1942–1943
Built from 1942 to 1943 by Marietta Manufacturing Company, Point Pleasant, West Virginia, these Template:Convert U.S Army mine planters were designed for diesel engines but low pressure steam plants were installed instead. Six of the vessels were transferred to the U.S. Navy as the Chimo class. Five vessels were later transferred to the U.S. Coast Guard and refitted as the Jonquil class of buoy tenders were after World War II.

- USAMP Colonel Henry J. Hunt (MP-2) (USS Bastion (ACM 6) then USCGC Jonquil (WAGL / WLB-330))
- USAMP Colonel George Armistead (MP-3) (USS Barbican (ACM-5) then USCGC Ivy (WLB-329/WAGL-329))
- USAMP 1st Lt. William G. Sylvester (MP-5) (USS Obstructor (ACM 7) then USCGC Heather (WABL / WLB-331))
- USAMP Colonel John Storey (MP-8) (USS Barricade (ACM 3) then USCGC Magnolia (WAGL / WLB-328))
180' – class ships
Two classes of purpose-built, rather than refitted mine planters, Coast Guard seagoing buoy tenders have been produced. The first was the 180 ft-class cutters, which were Template:Convert long. Thirty-nine of these vessels were built from 1942–1944. All but one were constructed in the shipyards of Duluth, Minnesota. The 180 fleet, many of which served for more than 50 years, all went through different mid-life modifications that essentially resulted in three different classes of ship. All of the 180s are now retired and have been replaced with the Template:Convert Juniper-class cutters. The last 180-foot cutter, Template:USCGC, was decommissioned on 7 June 2006.

225' – Juniper-class ships
The Juniper class ships, launched in the late 1990s, are the second class of purpose-built Coast Guard seagoing buoy tenders. They are designed and operated as multi-mission platforms. While the 180s also performed other Coast Guard missions, they lacked the speed, communications, navigation and maneuverability of the new Junipers. Today, the Junipers conduct almost as much law enforcement as aid to navigation work; they are also outfitted to handle oil spill recovery, search and rescue, homeland security, and some ice breaking operations. The Juniper class uses Dynamic Positioning which allows maintenance of the vessel's position within a Template:Convert circle in winds of up to Template:Convert and waves of up to Template:Convert.
