USS Crow (AMS-7)
USS ''Crow'' (AMS-7/YMS-215) was a acquired by the U.S. Navy for the task of removing mines that had been placed in the water to prevent ships from passing. ''Crow'' was constructed by Robert Jacob Inc., City Island, New York. She was laid down on 18 August 1942, launched on 22 February 1943, and was ready-for-sea on 22 July 1943. ''YMS-215'' was reclassified ''AMS-7'' on 17 February 1947 and named ''Crow'' the following day. ''Crow'' was struck from the Navy list A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval autho ... on 1 November 1959.

3"/50 Caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships. Low-angle 3"/50 caliber guns (Marks 3, 5, 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Mount
A gun is a ranged weapon designed to use a shooting tube (gun barrel) to launch projectiles. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons, spray guns for painting or pressure washing, projected water disruptors, and technically also flamethrowers), gas (e.g. light-gas gun) or even charged particles (e.g. plasma gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Taser guns, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within the barrel tube, produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 today. 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 (''Seeba ...

Machine Guns
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City Island, New York
City Island is a neighborhood in the northeastern Bronx in New York City, located on an island of the same name approximately long by wide. City Island is located at the extreme western end of Long Island Sound, south of Pelham Bay and east of Eastchester Bay. At one time the island was incorporated within the boundaries of Pelham, Westchester County, New York, but the island is now part of New York City. City Island is part of the Pelham Islands, a group of islands that once belonged to Thomas Pell. The body of water between City Island and the even smaller, uninhabited Hart Island to the east is known as City Island Harbor. The small island adjacent to the northeast is High Island. The Stepping Stones Light, marking the main shipping channel into New York, is off the southern tip of City Island, near the Long Island shore. As of the 2010 Census, the island had a population of 4,362. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navy List
A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval authorities of a country. Background The Navy List fulfills an important function in international law in that warships are required by article 29 of the United Nations Convention on the Law of the Sea to be commanded by a commissioned officer whose name appears in the appropriate service list. Past copies of the Navy List are also important sources of information for historians and genealogists. The Navy List for the Royal Navy is no longer published in hard-copy. The Royal Navy (United Kingdom) publishes annual lists of active and reserve officers, and biennial lists of retired officers. As of 2015, the Navy List of the Royal Navy has been renamed as the 'Navy Directory'. The equivalent in the United States Navy is the Naval Register, whic ...

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 of , and a 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 mount, two 20 mm 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 and particularly unsteady. These conditions were described (and surely exaggerated) by one aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built In City Island, Bronx
A ship is a large watercraft that travels the world's oceans and other sufficiently deep 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. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. 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. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...
