Driggs-Schroeder
Driggs-Schroeder was the name of several naval guns designed by US Navy officers William H. Driggs and Seaton Schroeder for the United States Navy in the late 1880s, fitted on ships built in the 1890s. Some Driggs-Schroeder weapons were also adopted by the US Army. Driggs later founded the Driggs-Seabury Ordnance Company in 1897, in partnership with his brother Louis Labadie "L. L." Driggs and Samuel Seabury, a retired US Navy officer. Driggs-Schroeder weapons included 1-pounder, 3-pounder (Navy Marks 2 and 3), and 6-pounder (Navy Marks 6 and 8)American Ordnance, pp. 37–39 naval guns. All were rapid-firing, which today would be called "single shot", with brass cased ammunition. They were among numerous models of these guns equipped on US Navy ships of the 1890s. Unlike some other manufacturers, Driggs-Schroeder did not design fully automatic 1-pounder and 3-pounder guns. Most Driggs-Schroeder weapons were manufactured by the American Ordnance Company in Bridgeport, Connecticu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QF 6-pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defense guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defense guns. The last ships to carry 6-pounders were the Aegir-cl ...

Driggs-Seabury
Driggs-Seabury Ordnance Company was founded in 1897 by William H. Driggs and Samuel Seabury, both US Navy officers, in partnership with William's brother Louis Labadie "L. L." Driggs, originally to produce guns for the US Army and US Navy designed by the partners. After a few reorganizations and an entry into the motor vehicle market, the company reorganized again in 1925; its ultimate fate is unclear from references. History Driggs-Seabury was preceded by the Driggs-Schroeder series of weapons, designed by W. H. Driggs and Seaton Schroeder in the late 1880s and produced by the American Ordnance Company in the 1890s. Driggs-Seabury incorporated the former Seabury Gun Company at its founding. Driggs-Seabury's plant was initially in Derby, Connecticut, in the former Brady Manufacturing facility.Williford, p. 222 Although Seabury died in 1902, followed by Driggs in 1908, the company continued under the leadership of Driggs' brother Louis Labadie "L. L." Driggs until at least 1935. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Warren (Massachusetts)
Fort Warren is a historic fort on the Georges Island at the entrance to Boston Harbor. The fort is named for Revolutionary War hero Dr. Joseph Warren, who sent Paul Revere on his famous ride, and was later killed at the Battle of Bunker Hill. The name was transferred in 1833 from the first Fort Warren – built in 1808 – which was renamed Fort Winthrop. Fort Warren is a pentagonal bastion fort, made with stone and granite, and was constructed from 1833 to 1861, completed shortly after the beginning of the American Civil War. Fort Warren defended the harbor in Boston, Massachusetts, from 1861 through the end of World War II, and during the Civil War served as a prison for Confederate officers and government officials, including Confederate Vice President Alexander H. Stephens. The fort remained active through the Spanish–American War and World War I, and was re-activated during World War II. It was permanently decommissioned in 1947, and is now a tourist site. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QF 3-pounder Hotchkiss
The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts. Operational history French service The French Navy used two versions of the Hotchkiss 3-pounder: the short-barreled M1885 and the long-barreled M1902, which had a larger muzzle velocity than its predecessor. The French L/40 M1885 and the British QF 3-pounder were largely the same gun. Like the British who paired their 3-pounders with the larger QF 6-poun ...

4"/40 Caliber Gun
The 4"/40 caliber gun (spoken "four-inch-forty-caliber") was used for the secondary batteries on the United States Navy's battleship , protected cruisers, and the armored cruiser , and was the primary batteries on the gunboats , , and . Design The Mark 1 Mod 0 was a built-up gun constructed in a length of 40 caliber. The Mod 0 had a tube, jacket, and two hoops, hooped to from the muzzle, all of gun steel. All Mark 1s were fitted with slotted-screw breeches but were later refitted with Fletcher rapid-fire breeches. The Mark 1 was described in the 1902 handbook as the M1889. The Mod 1 was of similar construction as the Mark 1 Mod 0 but had a screw-box liner and chamber liner so that it could use fixed ammunition instead of bag like the Mod 0 with all Mark 1s having their chambers bored out to diameter with a liner inserted so they could all use fixed ammunition in 1900. All Mark 1, 2, and 3 guns, were mounted on rapid-fire recoil mounts. The Mark 2 only consisted of two guns, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

QF 1-pounder Pom-pom
The QF 1 pounder, universally known as the pom-pom due to the sound of its discharge, was a 37 mm British autocannon, the first of its type in the world. It was used by several countries initially as an infantry gun and later as a light anti-aircraft gun. History Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun. Its longer range necessitated exploding projectiles to judge range, which in turn dictated a shell weight of at least , as that was the lightest exploding shell allowed under the Saint Petersburg Declaration of 1868 and reaffirmed in the Hague Convention of 1899. Early versions were sold under the Maxim-Nordenfelt label, whereas versions in British service (i.e. from 1900) were labelled Vickers, Sons and Maxim (VSM) as Vickers had bought out Maxim-Nordenfelt in 1897 but they are the same gun. Service by nation Belgium The Belgian Army used the gun on a high-angle field carriage mounting. Finlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seacoast Defense In The United States
Seacoast defense was a major concern for the United States from its independence until World War II. Before Military aviation, airplanes, many of America's enemies could only reach it from the sea, making coastal forts an economical alternative to Standing army, standing armies or a large navy. After the 1940s, it was recognized that fixed fortifications were obsolete and ineffective against aircraft and missiles. However, in prior eras foreign fleets were a realistic threat, and substantial fortifications were built at key locations, especially protecting major harbors. The defenses heavily depended on fortifications but also included Submarine mines in United States harbor defense, submarine minefields, nets and boom (navigational barrier), booms, ships, and airplanes. Therefore, all of the armed forces participated in seacoast defense, but the United States Army Corps of Engineers, U.S. Army Corps of Engineers played the central role in constructing fixed defenses.

Harbor Defenses Of Manila And Subic Bays
The Harbor Defenses of Manila and Subic Bays ("Coast Defenses of Manila and Subic Bays" until 1925) (a.k.a. CD/HD Manila Bay) were a United States Army Coast Artillery Corps harbor defense command, part of the Philippine Department of the United States Army from circa 1910 through early World War II. The command primarily consisted of four forts on islands at the entrance to Manila Bay and one fort on an island in Subic Bay.McGovern and Berhow 2003, pp. 7-12 Background and construction The United States acquired the Philippines as a territory as a result of the Spanish–American War in 1898. The Taft Board of 1905 recommended extensive, then-modern fortifications at the entrance to Manila Bay. The islands there had been declared military reservations on 11 April 1902. Accordingly, El Fraile, Carabao, Corregidor, Grande, and Caballo Islands in the Philippines were to be fortified and incorporated into the harbor defenses of Manila and Subic Bays, protecting the bases of the ...

Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for naval gunfire support, shore bombardment and anti-aircraft roles. The term generally refers to tube-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire, fire-throwers. From the late Middle Ages onwards, warships began to carry cannon, cannons of various calibres. The Mongol invasion of Java introduced cannons to be used in naval warfare (e.g. Cetbang by the Majapahit). The Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiscal Year
A fiscal year (or financial year, or sometimes budget year) is used in government accounting, which varies between countries, and for budget purposes. It is also used for financial reporting by businesses and other organizations. Laws in many jurisdictions require company financial reports to be prepared and published on an annual basis but generally not the reporting period to align with the calendar year (1 January to 31 December). Taxation laws generally require accounting records to be maintained and taxes calculated on an annual basis, which usually corresponds to the fiscal year used for government purposes. The calculation of tax on an annual basis is especially relevant for direct taxes, such as income tax. Many annual government fees—such as council tax and license fees, are also levied on a fiscal year basis, but others are charged on an anniversary basis. Some companies, such as Cisco Systems, end their fiscal year on the same day of the week each year: the day ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...
