She was converted at Sydney, Australia, into an , shortly after commissioning, and used in the repairing of landing craft. Named after the Greek hero Achilles, she was the only US Naval vessel to bear the name. Construction and career ''LST-455'' was laid down on 3 August 1942, under Maritime Commission (MARCOM) contract, MC hull 975, by Kaiser Shipyards, Vancouver, Washington; launched on 17 October 1942; and commissioned on 30 January 1943. Service in the United States Navy World War II Adjudged ready for service, ''LST-455'' sailed from San Diego on 20 February, for San Francisco and shifted thence to Hunters Point Naval Shipyard, and, later, to the Mare Island Navy Yard, Vallejo, where she completed fitting out and manning. She cleared the Golden Gate on 8 March, bound for the South Pacific and, a month and a day later, arrived in Samoan waters, en route to Australia. ...

Mare Island Navy Yard
The Mare Island Naval Shipyard (MINSY) was the first United States Navy base established on the Pacific Ocean. It is located northeast of San Francisco in Vallejo, California. The Napa River goes through the Mare Island Strait and separates the peninsula shipyard (Mare Island, California) from the main portion of the city of Vallejo. MINSY made a name for itself as the premier U.S. West Coast submarine port as well as serving as the controlling force in San Francisco Bay Area shipbuilding efforts during World War II. The base closed in 1996 and has gone through several redevelopment phases. It was registered as a California Historical Landmark in 1960, and parts of it were declared a National Historic Landmark District in 1975. Beginnings In September 1849, Lieutenant Commander William Pope McArthur was placed in command of the US survey schooner ''Ewing'', which had been brought around Cape Horn to the West Coast by Lieutenant Washington Allon Bartlett.

Dual-purpose Gun
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets. Description Second World War-era capital ships had four classes of artillery: the heavy main battery, intended to engage opposing battleships and cruisers of 305 mm to 457 mm (12 inch to 18 inch); a secondary battery for use against enemy destroyers of 152 mm to 203 mm (6 inch to 8 inch); heavy anti-aircraft guns of 76 mm to 127 mm (3 inch to 5 inch), which could create barrages to knock out airplanes at a distance; finally, light rapid-fire anti-aircraft batteries (A/A) to track and bring down aircraft at close range. The light A/A was dispersed throughout the ship and included both automatic cannons of 20 mm to 40 mm (.787 inch to 1.57 inch) and heavy machine guns of 12.7 mm to 14.5 mm (.50 inch to .58 inch). During World War II, the US Navy, Royal Navy, the French Navy, and the Imperial Japanese Navy combined the secondary battery with the heavy anti-aircraft guns, creating a d ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Maritime Commission
The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, which was passed by Congress on June 29, 1936, and was abolished on May 24, 1950. The commission replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet. As a symbol of the rebirth of the U.S. Merchant Marine and Merchant Shipbuilding under the Merchant Marine Act, the first vessel contracted for ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) 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. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...
