Rye, New Hampshire
Rye is a town in Rockingham County, New Hampshire, United States. The population was 5,543 at the 2020 census. The town is home to several state parks along the Atlantic coastline. History The first settlement in New Hampshire, originally named Pannaway Plantation, was established in 1623 at Odiorne's Point by a group of fishermen led by David Thompson. The settlement was abandoned in favor of Strawbery Banke, which became Portsmouth. The first settler in present-day Rye was probably William Berry. Prior to its incorporation in 1726 as a parish of New Castle, Rye was called "Sandy Beach" and its lands were once parts of New Castle, Portsmouth, Greenland and Hampton. In 1726, the town of New Castle set off a parish for Sandy Beach called "Rye", for Rye in Sussex, England, the ancestral lands of the Jenness family who continue to live in the town to this day and even have a beach named after them. The town was incorporated in 1785. In 2013, a researcher pointed out that the to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretary Of War
The secretary of war was a member of the U.S. president's Cabinet, beginning with George Washington's administration. A similar position, called either "Secretary at War" or "Secretary of War", had been appointed to serve the Congress of the Confederation under the Articles of Confederation between 1781 and 1789. Benjamin Lincoln and later Henry Knox held the position. When Washington was inaugurated as the first President under the Constitution, he appointed Knox to continue serving as Secretary of War. The secretary of war was the head of the War Department. At first, he was responsible for all military affairs, including naval affairs. In 1798, the secretary of the Navy was created by statute, and the scope of responsibility for this office was reduced to the affairs of the United States Army. From 1886 onward, the secretary of war was in the line of succession to the presidency, after the vice president of the United States, the Speaker of the House of Representatives, ...

Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...

6-inch Gun M1
The 6-inch gun M1897 (152 mm) and its variants the M1900, M1903, M1905, M1908, and M1 (a.k.a. T2) were coastal artillery pieces installed to defend major American seaports between 1897 and 1945. For most of their history they were operated by the United States Army Coast Artillery Corps. They were installed on disappearing carriages or pedestal (a.k.a. barbette) mountings, and during World War II many were remounted on shielded barbette carriages. Most of the weapons not in the Philippines were scrapped within a few years after World War II. History In 1885, William C. Endicott, President Grover Cleveland's Secretary of War, was tasked with creating the Board of Fortifications to review seacoast defenses. The findings of the board illustrated a grim picture of existing defenses in its 1886 report and recommended a massive $127 million construction program of breech-loading cannons, mortars, floating batteries, and submarine mines for some 29 locations on the US coastline. ...

Coast Artillery Fire Control System
In the U.S. Army Coast Artillery Corps, the term fire control system was used to refer to the personnel, facilities, technology and procedures that were used to observe designated targets, estimate their positions, calculate firing data for guns directed to hit those targets, and assess the effectiveness of such fire, making corrections where necessary. Fire control instruments The Coast Artillery's early fire control instruments supported optical rangefinding and position finding, either horizontal base or vertical base, with both systems usually present for each fort. Early horizontal base rangefinding required two azimuth (a.k.a. bearing or deflection) instruments, preferably widely separated, and a communications system to transmit data to a plotting room and then to the guns. The instruments were often in bunkers called base end stations, as they defined the endpoints of a baseline. A base end station might be a two-story structure with a plotting room or other instrument ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plotting Room
A plotting room was the co-ordination centre of a fire control system for guns used against enemy ships or aircraft, whether naval guns or coastal artillery. The plotting room received data on ship or aircraft position and motion from fire control instruments or their operators and determined and transmitted the range and bearing (a.k.a. azimuth or deflection) the guns would fire on. Plotting rooms came into use in the early 1900s for coastal artillery and during World War I for warships as gun ranges increased, and were in general use through the 1970s on World War II-era ships (and into the 1990s on the US Navy's s). Warships had plotting rooms for naval fire control for guns from 5-inch to 18-inch calibre, including anti-aircraft use for the smaller guns. On armoured ships such as battleships and cruisers, plotting rooms were located in the armoured citadel, protected by both deck and belt armour. With a few exceptions (mostly in Scandinavia), coastal defence gun installa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casemate
A casemate is a fortified gun emplacement or armored structure from which artillery, guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to Ancient history, antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see #Antiquity: casemate wall, Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
16"/50 Caliber Mark 2 Gun
The 16"/50 caliber Mark 2 gun and the near-identical Mark 3 were guns originally designed and built for the United States Navy as the main armament for the ''South Dakota''-class battleships and s. The successors to the 16"/45 caliber gun Mark I gun, they were at the time among the heaviest guns built for use as naval artillery. As part of the Washington Naval Treaty of 1922, both of these ship classes were cancelled part way through construction, rendering surplus about 70 examples of the 16-inch/50 which had already been built. Twenty were released to the US Army, between 1922–1924, for use by the Coast Artillery Corps, the rest were kept in storage for future naval use. Only ten of the twenty available guns were deployed (in five two-gun batteries) prior to 1940.Berhow, p. 61 When the design of the began in 1938, it was initially assumed these ships would use the surplus guns. However, due to a miscommunication between the two Navy departments involved in the design, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

155 Mm Gun M1918
The Canon de 155 Grande Puissance Filloux (GPF) modèle 1917 was a WWI-era French-designed 155 mm gun used by the French Army and the United States Army during the first half of the 20th century in towed and self-propelled mountings. History The gun was designed during the First World War by Colonel Louis Filloux to meet an urgent need for modern heavy artillery and became the standard heavy field gun of the French Army from 1917 until the Second World War. It was also adopted by the United States as the M1917 and a close derivative of it was made in and used by the US as the M1918 through the Second World War. The design adopted the split trail invented by French Colonel Deport in the early 1910s (see Cannone da 75/27 modello 11), and unlike the previous pieces, which had their carriages riveted from machined and/or pressed steel parts, utilized very large steel castings. The gun was also manufactured in the United States from 1917, after the US switched to metric art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
