USS Picket (ACM–8) was a Chimo-class minelayer of the United States Navy during World War II.


Picket was completed 15 April 1942 by Marietta Manufacturing Co., Point Pleasant, West Virginia, as the U.S. Army mine planter USAMP-1 General Henry Knox as the first of the WW II period planters [1] built for the U.S. Army Mine Planter Service. USAMP Knox was transferred to the U.S. Navy 2 January 1945; completed conversion to an Auxiliary Minelayer, ACM-8, at Charleston Navy Yard 5 March 1945; and commissioned 6 March 1945, Lt. Robert F. Harwood in command.

Service history

Pacific Theatre operations

Picket departed Charleston, South Carolina on 11 March 1945, and arrived Little Creek, Virginia, 13 March. Following shakedown, she reported for duty 3 April to Commander, Service Force, Atlantic, Norfolk, Virginia. Loaded with minesweeping equipment, she departed Norfolk 26 April, transited the Panama Canal 7 May, and arrived San Diego, 20 May. Following training, Picket departed San Diego 9 June, and proceeded via Pearl Harbor, Eniwetok, Guam, and Saipan to Okinawa, arriving 28 July to serve as minesweeper tender.

Picket departed Okinawa on 16 August, and, following rendezvous with Task Force 31 on the 21st, she entered Tokyo Bay on the 28th. With minesweepers, she departed Tokyo Bay on 12 September, and arrived at Wakayama, Japan, on the 14th.

Sailing from Kii Suido on 20 September, she entered the Inland Sea on the 22nd. Through 31 October she operated with minesweepers to clear the approaches to Hiro, Kure, Gunchū, and Matsuyama for U.S. Army landings.

Following postwar occupation duties, Picket returned to the United States. She decommissioned 24 June 1946, and was transferred to the U.S. Coast Guard that date. She was struck from the Naval Vessel Register 19 July 1946.

U.S. Coast Guard

The ex-Picket (ACM 8) ex-General Henry Knox was commissioned 20 September 1947 as USCGC Willow (WAGL/WLB-332). The ship was converted to a buoy tender and assigned to San Juan, Puerto Rico from 23 July 1947 until transfer to San Francisco, California during June 1949. Willow's area of responsibility extended from San Luis Obispo Bay to the Golden Gate, northern San Francisco Bay, San Pablo Bay and Suisun and shared logistics support of the Farallon Island Light Station and the San Francisco Lightship with USCGC Magnolia (WAGL/WLB-328). On 10 October 1969 Willow was decommissioned and stored at the Coast Guard Training Support Center in Alameda, California. As a buoy tender, the largest in the Coast Guard at time of conversion, duties were tending navigational aids and conducting search and rescue and law enforcement as needed. [2]

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. Light House 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.

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.

<i>Major General Wallace F. Randolph</i> (ship) Mine planter of The US Army

The ship was transferred to the U.S. Navy in 1951, placed directly into the Atlantic Reserve Fleet without being commissioned classed as the auxiliary minelayer ACM-15, then reclassified minelayer, auxiliary (MMA) and named MMA-15, and finally given the name Nausett without any active naval service. After being stricken from the Naval Vessel Register, the ship was transferred to different owners, and eventually was scuttled off the coast of Florida as an artificial reef and fish aggregating device. The site is currently known as the Thunderbolt Wreck, and is considered to be an excellent and challenging dive site for advanced divers.

Mine Planter Service

The U.S. Army Mine Planter Service (AMPS) was an outgrowth of civilian crewed Army mine planter ships dating back to 1904. It was established on July 22, 1918 by War Department Bulletin 43 and placed the Mine Planter Service under the U.S. Army Coast Artillery Corps. Its purview was to install and maintain the underwater minefields that were part of the principal armament of U.S. coastal fortifications, including those at the approaches to the Panama Canal and the defenses of Manila Bay in the Philippines.

Mine planter

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.

Three cutters of the United States Coast Guard have been named Willow

USCGC Acacia (WAGL-200) was originally built for service by the U.S. Army as a mine planter shortly after World War I and later transferred to the U.S. Lighthouse Service, which became part of the U.S. Coast Guard in 1939; when transferred the ship was redesignated as a Speedwell-class buoy tender. She was sunk in 1942 by a German U-boat.
