Tacoma Boatbuilding Company
Tacoma Boatbuilding Company (sometimes Tacoma Boat) was a shipyard at 1840 Marine View Drive, Tacoma, Washington, in the United States. It was established in 1926 and closed in 1992. History Tacoma Boat was established in 1926 and built many boats during World War II. The shipyard grew rapidly in the 1970s and early 1980s but got into difficulty with several large government contracts and filed for Chapter 11 protection in 1985. It emerged from bankruptcy in 1986 but could not recover and closed in 1992. In 1998, the company was liquidated Liquidation is the process in accounting by which a company is brought to an end in Canada, United Kingdom, United States, Ireland, Australia, New Zealand, Italy, and many other countries.

Asheville Class Gunboat
The ''Asheville''-class gunboats were a class of small warships built for the United States Navy in response to the Cuban Missile Crisis. The class is named for a city in western North Carolina and the seat of Buncombe County. All ''Asheville''-class gunboats have since been donated to museums, scheduled for scrapping, or transferred to the Greek, Turkish, Colombian and South Korean Navies. The last two Asheville-class gunboats in US service were and , which were operated by the Naval Surface Warfare Center until they were stricken in 2016. Origination The ''Asheville''-class gunboats were originally designated PGM motor gunboats, but were reclassified in 1967 as PG patrol combatant ships. The ''Asheville'' class employed a combined diesel or gas turbine (CODOG) propulsion system; twin Cummins diesel engines for endurance, and a GE LM1500 gas turbine for high-speed dash. Engine controls were operated by pneumatics. The controllable reversible pitch propeller allowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Diesel Or Gas
Combined diesel or gas (CODOG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes. For every propeller shaft there is one diesel engine for cruising speed and one geared gas turbine for high speed dashes. Both are connected to the shaft with clutches; only one system is driving the ship, in contrast to CODAG systems that can use the combined power output of both. The advantage of CODOG is a simpler gearing compared to CODAG, but it needs either more powerful or additional gas turbines to achieve the same maximum power output. The disadvantage of CODOG is that the fuel consumption at high speed is poor compared to CODAG.

Exocet
The Exocet () is a French-built anti-ship missile whose various versions can be launched from surface vessels, submarines, helicopters and fixed-wing aircraft. Etymology The missile's name was given by M. Guillot, then the technical director at Nord Aviation. It is the French word for flying fish, from the Latin ''exocoetus'', a transliteration of the Greek name for the fish that sometimes flew into a boat: (''exōkoitos''), literally "lying down outside (, ), sleeping outside". Description The Exocet is built by MBDA, a European missile company. Development began in 1967 by Nord as a ship-launched weapon named the MM38. A few years later, Aerospatiale and Nord merged. The basic body design was based on the Nord AS-30 air-to-ground tactical missile. The sea-launched MM38 entered service in 1975, whilst the air-launched AM39 Exocet began development in 1974 and entered service with the French Navy five years later in 1979. The relatively compact missile is designed for at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bofors
AB Bofors ( , , ) is a former Swedish arms manufacturer which today is part of the British arms concern BAE Systems. The name has been associated with the iron industry and artillery manufacturing for more than 350 years. History Located in Karlskoga, Sweden, the company originates from the hammer mill "Boofors", which was founded as a royal state-owned company in 1646. The modern corporate structure was created in 1873 with the foundation of Aktiebolaget (AB) Bofors-Gullspång. The Bofors Works was acquired by Johan Eberhard Geijer in 1762. It was then acquired by the latter's brother, Emanuel af Geijerstam. A leading Swedish steel producer by the early 1870s, when steel began to be used for gun manufacture in Sweden, Bofors initially sold cast and forged steel produced by the Siemens-Martin process to Finspång gun works, but soon started to expand into weapons manufacture. The company's first cannon workshop was opened in 1884. Bofors' most famous owner was Alfred Nob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboats
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to shore bombardment, bombard coastal targets, as opposed to those military craft designed for naval warfare, or for troopship, ferrying troops or auxiliary ship, supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Republic Of Korea Navy
The Republic of Korea Navy (ROKN; ko, 대한민국 해군), also known as the ROK Navy or South Korean Navy, is the naval warfare service branch of the South Korean armed forces, responsible for naval and amphibious operations. The ROK Navy includes the Republic of Korea Marine Corps, which functions as a branch of the Navy. The ROK Navy has about 70,000 regular personnel including 29,000 Republic of Korea Marines.

Patrol Vessels
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine ("blue water"), estuarine ("green water"), or river ("brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti-smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost make them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
