John Francis Sheehan
USS ''Sheehan'' (DE-541) was a United States Navy ''John C. Butler''-class destroyer escort launched during World War II but never completed. Namesake John Francis Sheehan was born on 20 January 1910 at Fall River, Massachusetts. He enlisted in the U.S. Navy on 25 October 1928 at the Navy Recruiting Station at Boston, Massachusetts as a seaman apprentice and transferred the same day to the Naval Training Center at Newport, Rhode Island. Sheehan was rated seaman 2nd class on 27 February 1929, quartermaster 3rd class on 28 July 1930, quartermaster 2nd class on 16 November 1936, quartermaster 1st class on 16 February 1938, and chief quartermaster (acting appointment) on 1 March 1942. Sheehan was assigned to protected cruiser on 21 January 1929 and served aboard her until 24 October 1929. He went on to serve aboard minesweeper from 1929 to 1932, heavy cruiser from 1932 to 1934, gunboat from 1934 to 1937, and light cruiser from 1937 to 1939. He was stationed at Subm ...

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 t ...

Seaman Apprentice
Constructionman Apprenticevariation Fireman Apprenticevariation Airman Apprenticevariation Seaman Apprenticeinsignia Collarinsignia Seaman apprentice is the second lowest enlisted rate in the U.S. Navy, U.S. Coast Guard, and the U.S. Naval Sea Cadet Corps just above seaman recruit and below seaman; this rank was formerly known as seaman second class. The current rank of seaman apprentice should not be confused with the rank of apprentice seaman which was the lowest Navy rank from 1904 to 1948. In the old system apprentice seaman was followed by seaman 2nd class and seaman 1st class. (The three tiered rank system for seamen dates from the 18th Century Royal Navy when the ranks were called landsman, ordinary seaman and able seaman.) The actual title for an E-2 in the U.S. Navy varies based on the community to which the sailor belongs. Likewise, the color of their group rate marks also depends on their community. * Those in the general deck and adminis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayonne, New Jersey
Bayonne ( ) is a city in Hudson County, New Jersey, United States. Located in the Gateway Region, Bayonne is situated on a peninsula located between Newark Bay to the west, the Kill Van Kull to the south, and New York Bay to the east. As of the 2020 United States census, the city's population was 71,686. Bayonne was originally formed as a township on April 1, 1861, from portions of Bergen Township. Bayonne was reincorporated as a city by an act of the New Jersey Legislature on March 10, 1869, replacing Bayonne Township, subject to the results of a referendum held nine days later.Snyder, John P''The Story of New Jersey's Civil Boundaries: 1606-1968'' Bureau of Geology and Topography; Trenton, New Jersey; 1969. p. 146. Accessed February 9, 2012. At the time it was formed, Bayonne included the communities of Bergen Point, Constable Hook, Centreville, Pamrapo and Saltersville. While somewhat diminished, traditional manufacturing, distribution, and maritime activities remain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Boat Company
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a un ...

New London, Connecticut
New London is a seaport city and a port of entry on the northeast coast of the United States, located at the mouth of the Thames River in New London County, Connecticut. It was one of the world's three busiest whaling ports for several decades beginning in the early 19th century, along with Nantucket and New Bedford, Massachusetts. The wealth that whaling brought into the city furnished the capital to fund much of the city's present architecture. The city subsequently became home to other shipping and manufacturing industries, but it has gradually lost most of its industrial heart. New London is home to the United States Coast Guard Academy, Connecticut College, Mitchell College, and The Williams School. The Coast Guard Station New London and New London Harbor is home port to the Coast Guard Cutter ''Coho'' and the Coast Guard's tall ship ''Eagle''. The city had a population of 27,367 at the 2020 census. The Norwich–New London metropolitan area includes 21 towns and 274,0 ...

Submarine Base New London
Naval Submarine Base New London is the primary United States Navy East Coast submarine base, also known as the "Home of the Submarine Force." It is located in Groton, Connecticut directly across the Thames River from its namesake city of New London. History In 1868, the State of Connecticut gave the Navy of land along the Thames River in Groton to build a Naval Station. Due to a lack of federal funding, it was not until 1872 that two brick buildings and a T-shaped pier were constructed and officially declared a Navy Yard. In 1898, Congress approved a coaling station to be built at the Yard for refueling small naval ships traveling through the waters of New England. The Navy Yard was first used for laying up inactive ships. The Congressional appropriations were small and the Navy had little need for the yard, which was closed from 1898 to 1900 and its personnel reassigned. By 1912, oil replaced coal in warships and again the Yard was scheduled for closure and the land relinqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small cru ...

Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or 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 quick to build, naval forces favoured sw ...

Heavy Cruiser
The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in caliber, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armored cruisers of the years before 1905. When the armored cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theaters.

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Protected Cruiser
Protected cruisers, a type of naval cruiser of the late-19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers, which had in addition a belt of armour along the sides. Evolution From the late 1850s, navies began to replace their fleets of wooden ships-of-the-line with armoured ironclad warships. However, the frigates and sloops which performed the missions of scouting, commerce raiding and trade protection remained unarmoured. For several decades, it proved difficult to design a ship which had a meaningful amount of protective armour but at the same time maintained the speed and range required of a "cruising warship". The first attempts to do so, armored cruisers like , proved unsatisfactory, generally lacking enough speed for their cruiser role. During the 1870s the increasing power of armour-piercing shells made a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartermaster
Quartermaster is a military term, the meaning of which depends on the country and service. In land armies, a quartermaster is generally a relatively senior soldier who supervises stores or barracks and distributes supplies and provisions. In many navies, a quartermaster is an officer with particular responsibility for steering and signals. The seaman is a non-commissioned officer (petty officer) rank; in some others, it is not a rank but a role related to navigation. The term appears to derive from the title of a German royal official, the . This term meant "master of quarters" (where "quarters" refers to lodging or accommodation). Alternatively, it could have been derived from "master of the quarterdeck" where the helmsman and captain controlled the ship. The term's first use in English was as a naval term, which entered English in the 15th century via the equivalent French and Dutch naval titles and , respectively. The term began to refer to army officers in English around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
