USS Flagstaff
''Flagstaff'' top, experimental coastal patrol and interdiction craft at center, and the PTF-23 bottom, off the coast of southern California in August 1974 USS ''Flagstaff'' (PGH-1) was the only ''Flagstaff''-class patrol gunboat (hydrofoil) and was acquired by the United States Navy because of her relatively low cost and very high speed. She was later loaned by the Navy to the U.S. Coast Guard, as USCGC ''Flagstaff'' (WPBH-1). The Coast Guard’s interest in the craft was the craft’s speed and its ability to interdict smugglers and other suspicious craft approaching the U.S. coast. History of evaluation of high speed craft In the mid-1970s, the Coast Guard explored options to replace the aging cutters. There was also considerable interest in developing new "high-speed ways" to combat narcotics smuggling by sea, conduct search and rescue operations, fisheries enforcement, and marine environmental protection. The Coast Guard, of course, looked for the most inexpensive way to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ship Characteristics Board
The Ship Characteristics Board was a unit of the United States Navy. The purpose of the Ship Characteristics Board was to coordinate the creation of 'ship characteristics' that are essential to the design of naval combatants and auxiliaries. Coordination was required because the operators and the designers of ships had different interests, perceptions, concepts, and constraints: as summarized by the naval historian Norman Friedman, "How to achieve the best possible compromise among competing bureaus has been one of the great dilemmas of 20th-century U.S. naval administration." This list of SCB projects is a useful exposition of the U.S. Navy's shipbuilding priorities in the first half of the Cold War. History The Ship Characteristics Board was founded in 1945 under the Office of the Chief of Naval Operations / OpNav. It was created after the body previously responsible for coordinating ships characteristics, the General Board, had been seen as ineffective in a series of ear ...

New Point Loma Lighthouse
The New Point Loma Lighthouse (officially Point Loma Light) is a lighthouse at the southern tip of the Point Loma peninsula in San Diego, California. History It was first lighted on March 23, 1891, replacing the Old Point Loma Lighthouse which is atop the cliffs of Point Loma; the old lighthouse was often obscured by fog. The new light is only above the water. The first lighthouse keeper was Robert Decatur Israel, who had been keeper at the old lighthouse for 18 years. The original light was 600,000 candlepower and could be seen at a distance of approximately 15 nautical miles. There was also a two-tone diaphone fog horn and living quarters for several families. The structure is the only pyramidal skeletal lighthouse remaining on the West Coast. It is very similar to Coney Island Light, Plum Island Range Rear Light, La Pointe Light, and Duluth South Breakwater Inner Light, all of which were built at about the same time. The latter three of these are all on the National R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Whale
The gray whale (''Eschrichtius robustus''), also known as the grey whale,Britannica Micro.: v. IV, p. 693. is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of , a weight of up to and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age. The common name of the whale comes from the gray patches and white mottling on its dark skin. Gray whales were once called devil fish because of their fighting behavior when hunted. The gray whale is the sole living species in the genus ''Eschrichtius''. It is the sole living genus in the family (biology), family Eschrichtiidae, however some recent studies classify it as a member of the family Rorqual, Balaenopteridae. This mammal is descended from filter-feeding whales that appeared during the Neogene. The gray whale is distributed in a Northeast Pacific (North American), and an endangered species, endangered Northwest Pacific (Asian), population. North Atla ...

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a Junior officer, junior commissioned officer rank in the armed forces of many nations, as well as fire services, emergency medical services, Security agency, security services and police forces. The rank in armies and air forces is often subdivided into subcategories of seniority. In Comparative navy officer ranks of Anglophone countries, English-speaking navies, lieutenants are often equivalent to the army rank of Captain (armed forces), captain; in other navies, the lieutenants are usually equal to their army counterparts. ''Lieutenant'' may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is "second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieu ...

Commanding Officer
The commanding officer (CO) or commander, or sometimes, if the incumbent is a general officer, commanding general (CG), is the officer in command of a military unit. The commanding officer has ultimate authority over the unit, and is usually given wide latitude to run the unit as they see fit, within the bounds of military law. In this respect, commanding officers have significant responsibilities (for example, the use of force, finances, equipment, the Geneva Conventions), duties (to higher authority, mission effectiveness, duty of care to personnel), and powers (for example, discipline and punishment of personnel within certain limits of military law). In some countries, commanding officers may be of any commissioned rank. Usually, there are more officers than command positions available, and time spent in command is generally a key aspect of promotion, so the role of commanding officer is highly valued. The commanding officer is often assisted by an executive officer (XO) or s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cam Ranh Bay
Cam Ranh Bay () is a deep-water bay in Vietnam in Khánh Hòa Province. It is located at an inlet of the South China Sea situated on the southeastern coast of Vietnam, between Phan Rang and Nha Trang, approximately 290 kilometers (180 miles) northeast of Ho Chi Minh City (formerly Saigon). Cam Ranh is considered the finest deepwater shelter in Southeast Asia. The continental shelf of Southeast Asia is relatively narrow at Cam Ranh Bay, bringing deep water close to land. Since 2011–2014, Vietnamese authorities have hired Russian consultants and purchased Russian technologies to re-open Cam Ranh Bay (a former United States and later Soviet military base) as the site of a new naval maintenance and logistics facility for foreign warships. Overview Historically, the bay has been significant from a military standpoint. The French used it as a naval base for their forces in French Indochina, Indochina. It was also used as a staging area for the 40-ship Russian Navy, Imperial Rus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
