Aylwin-class Destroyer
The ''Aylwin'' class was a class of four destroyers in the United States Navy; all served as convoy escorts during World War I. The ''Aylwin''s were the second of five "second-generation" 1000-ton four-stack destroyer classes that were front-line ships of the Navy until the 1920s. They were known as "thousand tonners". All were scrapped in 1935 to comply with the London Naval Treaty.Gardiner and Gray, p. 122 All four ships were built by William Cramp & Sons in Philadelphia.Bauer and Roberts, p. 170 These ships were built concurrently with the and in some references are considered to be in that class. In design and armament they were essentially repeats of the ''Cassin'' class. Design Unlike the other "thousand tonner" classes, the ''Aylwin''s were not a significant improvement on the previous class. Armament They retained the ''Cassin''s' armament of four /50 caliber Mark 9 guns and eight 18-inch (450 mm) torpedo tubes in twin broadside mounts. Compared with the previous o ...

William Cramp & Sons
William Cramp & Sons Shipbuilding Company (also known as William Cramp & Sons Ship & Engine Building Company) of Philadelphia was founded in 1830 by William Cramp, and was the preeminent U.S. iron shipbuilder of the late 19th century. Company history William Cramp was born in Kensington, Philadelphia in 1807. In 1855, his sons Charles Henry (born 1828) and William C., became partners with their father. In 1872, his other sons Samuel H., Jacob C. and Theodore were taken into the firm. The company was incorporated under the name "The William Cramp and Sons' Iron Shipbuilding and Engineering Company." The pilot boat ''Thomas Howard'' was built by the Cramp shipyard in 1870 for the Delaware Bay & River pilots. She was one of the Philadelphia port's fastest pilot boats. In 1890 the company built the battleships USS ''Indiana'' and USS ''Massachusetts'', armored cruiser USS ''New York'', and protected cruiser USS ''Columbia''. Three of these ships took a part in the battle with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westport, Connecticut
Westport is a town in Fairfield County, Connecticut, United States, along the Long Island Sound within Connecticut's Gold Coast. It is northeast of New York City. The town had a population of 27,141 according to the 2020 U.S. Census. History The earliest known inhabitants of the Westport area as identified through archaeological finds date back 7,500 years. Records from the first white settlers report the Pequot Indians living in the area which they called ''Machamux'' translated by the colonialists as ''beautiful land''. Settlement by colonialists dates back to the five ''Bankside Farmers''; whose families grew and prospered into a community that continued expanding. The settlers arrived in 1693, having followed cattle to the isolated area. The community had its own ecclesiastical society, supported by independent civil and religious elements, enabling it to be independent from the Town of Fairfield. As the settlement expanded its name changed: it was briefly known as "Banksid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Benham (DD-49)
USS ''Benham'' (Destroyer No. 49/DD-49) was an built for the United States Navy prior to the American entry into World War I. The ship was the first U.S. Navy vessel named in honor of Rear Admiral Andrew E. K. Benham. ''Benham'' was laid down by William Cramp & Sons of Philadelphia in March 1912 and launched in March 1913. The ship was a little more than in length, just over abeam, and had a standard displacement of . She was armed with four guns and had eight 18 inch (450 mm) torpedo tubes. ''Benham'' was powered by a pair of steam turbines that propelled her at up to . After her January 1914 commissioning, she assisted her sister ship when that ship suffered an explosion in one of her fire rooms in April. After a period in reserve, ''Benham'' served on Neutrality Patrol duty. As a part of that duty in October 1916, she was one of several U.S. destroyers sent to rescue survivors from five victims of German submarine off the Lightship Nantucket. She picked up officers ...

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Steam Turbines
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3"/23 Caliber Gun
The 3"/23 caliber gun (spoken "three-inch-twenty-three-caliber") was the standard anti-aircraft gun for United States destroyers through World War I and the 1920s. United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 23 calibers long (barrel length is 3" x 23 = 69" or 1.75 meters.) Description The built-up gun with vertical sliding breech block weighed about 531 pounds (241 kg) and used fixed ammunition (case and projectile handled as a single assembled unit) with a 13-pound (6 kg) projectile at a velocity of 1650 feet per second (500 m/s).Campbell 1985 p.146 Range was 10100 yards (9235 meters) at 45 degrees elevation. Ceiling was 18000 feet (5500 meters) at the maximum elevation of 75 degrees.Campbell 1985 p.146 History The 3"/23 caliber cannon was the first purposely-designed anti-aircraft cannon to reach operational service in the US military, and was a further development of a 1 pound ...

Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, 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-submarine missile from a s ...

General Board Of The United States Navy
The General Board of the United States Navy was an advisory body of the United States Navy, somewhat akin to a naval general staff and somewhat not. The General Board was established by general order 544, issued on March 13, 1900 by Secretary of the Navy John Davis Long. The order was officially recognized by Congress in 1916. The General Board was disbanded in 1951. Origins "The war with Spain had underlined the need for adequate staff work and the success of the War Board had pointed the way for the future. Among the most persistent advocates of a general staff for the Navy was Captain Henry C. Taylor. He had first laid plans for such a staff before Roosevelt in May 1897; now in 1900 he brought the idea once more to the attention of Secretary Long. Long, however, was reluctant to risk a fight with his entrenched bureau chiefs, hesitant about allowing the professional officers wide powers outside civilian control, and rightly dubious whether Congress could be brought to ap ...

London Naval Treaty
The London Naval Treaty, officially the Treaty for the Limitation and Reduction of Naval Armament, was an agreement between the United Kingdom, Japan, France, Italy, and the United States that was signed on 22 April 1930. Seeking to address issues not covered in the 1922 Washington Naval Treaty, which had created tonnage limits for each nation's surface warships, the new agreement regulated submarine warfare, further controlled cruisers and destroyers, and limited naval shipbuilding. Ratifications were exchanged in London on 27 October 1930, and the treaty went into effect on the same day, but it was largely ineffective. The treaty was registered in '' League of Nations Treaty Series'' on 6 February 1931. Conference The signing of the treaty remains inextricably intertwined with the ongoing negotiations, which began before the official start of the London Naval Conference of 1930, evolved throughout the progress of the official conference schedule, and continued for years ...
