Harbor Boat Building
Harbor Boat Building Company was a shipbuilding company on Terminal Island in San Pedro, California. To support the World War II demand for ships General Engineering built: minesweepers, torpedo boats, submarine chasers, and air-sea rescue boats. In 1919 Romolo Rados founded Harbor Boat Building. After the war he renamed the company Harco Shipyard and built and sold a standard design motor boat. In 1959 he sold the company to LTV. The shipyard was closed and the company was sold again in 1971 to Omega-Alpha, Inc. The last ship built was in 1965 for the US Navy. The shipyard was located at 263 Wharf St, San Pedro.

Ships Built In Los Angeles
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%). Nomenclature Ships are typically larger than boats, but there is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YMS-1-class Minesweepers Of The United States Navy
The ''YMS-1'' class of auxiliary motor minesweepers was established with the laying down of ''YMS-1'' on 4 March 1941. Some were later transferred to the United Kingdom as part of the World War II Lend-Lease pact between the two nations. One ship eventually made its way into the Royal Canadian Navy postwar. Design The design for the class had a displacement of 270 tonnes. The ships had a length of , a Beam (nautical), beam of , and a Draft (hull), draft of . The vessels were capable of , being powered by two General Motors (Cleveland) 8-268A, 2-cycle diesel engines which drove two shafts. The ships had a complement of 32. Their armament comprised one single 3-inch/50-caliber gun, 3-inch/50 caliber gun mount, two Oerlikon 20 mm cannon, 20 mm anti-air warfare, anti-aircraft guns and two depth charge projectors. ''YMS-1''-class ships were relatively small compared to larger contemporary US Navy ships. This led to a view by some sailors that the YMS-designated ships were cramped ...

Naval Vessel Register
The ''Naval Vessel Register'' (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register (often termed ''wikt:stricken, stricken'' or ''struck''), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are not included, but are gradually being added along with other updates. History The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published ''Ships Data US Naval Vessels'', which subsequently became the ''Ships Data Book'' in 1952 under the Bureau of Ships. The Bureau of Ordnance's ''Vessel Register'', first published in 1942 and ret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Minesweeper
Coastal minesweeper is a term used by the United States Navy to indicate a minesweeper intended for coastal use as opposed to participating in fleet operations at sea. Because of its small size—usually less than 100 feet in length—and construction—wood as opposed to steel—and slow speed—usually about 9 or 10 knots—the coastal minesweeper was considered too fragile and slow to operate on the high seas with the fleet. Minesweeping, in conjunction with fleet activities, was usually relegated to the diesel-driven steel-hulled AM-type minesweepers, later to be replaced by the wood-hulled MSO-type minesweeper with aluminum engines An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power gen ....

Crossbill
Crossbills are birds of the genus ''Loxia'' within the finch family (Fringillidae), with six species. These birds are characterized by the mandibles with crossed tips, which gives the group its English name. Adult males tend to be red or orange in color, and females green or yellow, but there is much variation. Crossbills are specialist feeders on conifer cones, and the unusual bill shape is an adaptation which enables them to extract seeds from cones. These birds are typically found in higher northern hemisphere latitudes, where their food sources grow. They irrupt out of the breeding range when the cone crop fails. Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies. Systematics and evolution The genus ''Loxia'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae''. The name is from the Ancient Greek , "crosswise". The Swiss naturalist Conrad Gessner had used the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depth Charge Projector
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarines by detonating in the water near the target and subjecting it to a destructive hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-subm ...

Terminal Island, California
Terminal Island, historically known as , is a largely artificial island located in Los Angeles County, California, between the neighborhoods of Wilmington and San Pedro in the city of Los Angeles, and the city of Long Beach. Terminal Island is roughly split between the Port of Los Angeles and Port of Long Beach. Land use on the island is entirely industrial and port-related except for Federal Correctional Institution, Terminal Island. History Before World War II The island was originally called Isla Raza de Buena Gente and later Rattlesnake Island. It was renamed Terminal Island in 1891. In 1909, the newly reincorporated Southern California Edison Company decided to build a new steam station to provide reserve capacity and emergency power for the entire Edison system and to enable Edison to shut down some of its small, obsolete steam plants. The site chosen for the new plant was on a barren mudflat known as Rattlesnake Island, today's Terminal Island in the San Pedro Bay. ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...
