USS Rochester (CA-2)
USS ''New York'' (ACR-2/CA-2) was the second United States Navy armored cruiser so designated; the first was the ill-fated , which was soon redesignated a second-class battleship. Due to the unusually protracted construction of ''Maine'', ''New York'' was actually the first armored cruiser to enter U.S. Navy service. The fourth Navy ship to be named in honor of the state of New York, she was later renamed ''Saratoga'' and then ''Rochester''. With six 8-inch guns, she was the most heavily armed cruiser in the US Navy when commissioned.Gardiner and Chesneau, p. 147Bauer and Roberts, p. 133 She was laid down on 19 September 1890 by William Cramp & Sons, Philadelphia, launched on 2 December 1891, and sponsored by Miss Helen Clifford Page, the daughter of J. Seaver Page, the secretary of the Union League Club of New York. ''New York'' was commissioned 1 August 1893, Captain John Philip in command.

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] |
United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck (ship)
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists tension, compression, and racking forces. The deck's scantling is usually the same as the topsides, or might be heavier if the deck is expected to carry heavier loads ...

Belt Armor
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards. Typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the outer hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection, as described above. The torpedo bulkhead Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Saluting Gun
A salute is usually a formal hand gesture or other action used to display respect in military situations. Salutes are primarily associated with the military and law enforcement, but many civilian organizations, such as Girl Guides, Boy Scouts and the Salvation Army use formal salutes. Ordinary civilians also salute informally to greet or acknowledge the presence of another person; such as a tip of the hat or a hand wave to a friend or neighbour. Military salutes Throughout history, military organizations have used many methods to perform salutes. Depending on the situation a salute could be a hand or body gesture, cannon or rifle shots, hoisting of flags, removing headgear, or other means of showing respect or deference. Hand salutes Origins According to historical reconstruction, the ancient Roman military salute (''salutatio militaris'') was analogous to the current military salute. According to some modern military manuals, the modern Western salute originated i ... [...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] |
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 ...

Quick-firing Gun
A quick-firing or rapid-firing gun is an artillery piece, typically a gun or howitzer, which has several characteristics which taken together mean the weapon can fire at a fast rate. Quick-firing was introduced worldwide in the 1880s and 1890s and had a marked impact on war both on land and at sea. Characteristics The characteristics of a quick-firing artillery piece are: *A breech-loading weapon with a breech mechanism that allows rapid reloading *Single-part cased ammunition, i.e. a cartridge containing both shell and propellant *Recoil buffers to limit recoil, so the barrel can quickly return to the same position after firing *The use of smokeless powder – nitrocellulose, nitroglycerine, or cordite – which create far less smoke than gunpowder, meaning that gun crews could still see their target These innovations, taken together, meant that the quick-firer could fire aimed shells much more rapidly than an older weapon. For instance, an Elswick Ordnance Company 4.7-inch gun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
