The Thomaston class was a class of eight dock landing ships built for the United States Navy in the 1950s.

Contents

The class is named after a town of Thomaston, Maine, which was the home of General Henry Knox, the first Secretary of War to serve under the United States Constitution. [2]

Design

The Thomaston class was the third class of U.S. Navy dock landing ships. The class was designed under project SCB 75 and approved in the early 1950s. Compared to the Ashland and Casa Grande-class dock landing ships of World War II, the ships of this class were about a third larger and five knots faster. [3] The class was designed to be able to transport:

The dock was covered by removable segments that were able to carry the weight of two medium helicopters. Both cranes could lift weights of up to 50 tons. The machinery spaces were located underneath the dock, in contrast to the earlier Ashland class, where the machinery spaces were located to port and starboard of the dock.

Originally, all ships were armed with eight 3"/50 caliber gun Mark 33 twin mounts. The number was later reduced.

Spiegel Grove was a trial ship for the Jeff(A) and Jeff(B) landing craft in the mid-1980s. Jeff(B) was then developed into the Landing Craft Air Cushion. All ships were decommissioned by the U.S. Navy between 1983 and 1990, Alamo and Hermitage were sold to Brazil in 1989–1990. [4]

Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States.

<span class="mw-page-title-main">Dock landing ship</span> Type of amphibious warfare ship

A dock landing ship is an amphibious warfare ship with a well dock to transport and launch landing craft and amphibious vehicles. Some ships with well decks, such as the Soviet Ivan Rogov class, also have bow doors to enable them to deliver vehicles directly onto a beach. Modern dock landing ships also operate helicopters.

Landing Ship, Tank Amphibious assault ship of World War II

A landing ship, tank, (LST) is a ship first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto a low-slope beach with no docks or piers. The shallow draft and bow doors and ramps enabled amphibious assaults on almost any beach.

<i>Newport</i>-class tank landing ship US Navy tank landing ship class in service 1969 to 2002

Newport-class tank landing ships were an improved class of tank landing ship (LST) designed for and employed by the United States Navy from 1969 to 2002. The ships were intended to provide substantial advantages over their World War II-era predecessors. Larger and faster than any previous LST design, they carried a ramp over the bow that allowed them to surpass 20 knots, a goal of the United States amphibious forces. 27 were planned of which twenty were completed, the high number due to the demands of US force projection estimates. However, the arrival of the air-cushioned landing craft which allowed for over-the-horizon attacks made the class obsolete in the eyes of the United States Navy. Placed in reserve, twelve were eventually sold to foreign navies, while the remaining eight have since been decommissioned.

An amphibious assault ship is a type of warship employed to land and support ground forces on enemy territory during an armed conflict.

LCM 1 Landing craft used in WWII

The Landing Craft, Mechanised Mark 1 or LCM (1) was a landing craft used extensively in the Second World War. Its primary purpose was to ferry tanks from transport ships to attack enemy-held shores. Ferrying troops, other vehicles, and supplies were secondary tasks. The craft derived from a prototype designed by John I. Thornycroft Ltd. of Woolston, Hampshire, UK. During the war it was manufactured in the United Kingdom in boatyards and steel works. Constructed of steel and selectively clad with armour plate, this shallow-draft, barge-like boat with a crew of 6, could ferry a tank of 16 long tons to shore at 7 knots (13 km/h). Depending on the weight of the tank to be transported the craft might be lowered into the water by its davits already loaded or could have the tank placed in it after being lowered into the water.

LCM (2) Vessel used for amphibious landings by the US in World War Two

The Landing Craft, Mechanized Mark 2 or LCM (2) was a landing craft used for amphibious landings early in the United States' involvement in the Second World War. Though its primary purpose was to transport light tanks from ships to enemy-held shores, it was also used to carry guns and stores. The craft was designed by the Navy's Bureau of Construction and Repair and the initial production contract was let to the American Car & Foundry Company. A total of 147 were built by this company and Higgins Industries. Because of its light load capacity and the rapid production of the superseding LCM (3), the LCM (2) quickly fell out of use following the Allied invasion of North Africa in 1942.
