USS Milwaukee (C-21)
The second USS ''Milwaukee'' (C-21) was a protected cruiser in the United States Navy. Entering service in 1906, ''Milwaukee'' was deployed to the Pacific Ocean. On 13 January 1917, while aiding a grounded submarine, the cruiser grounded herself. The ship was decommissioned and sold for scrap in 1919. Construction and commissioning ''Milwaukee'' was laid down on 30 July 1902 by Union Iron Works at San Francisco, California, and launched on 10 September 1904, sponsored by Miss Janet Mitchell, daughter of U.S. Senator John L. Mitchell of Wisconsin. The cruiser was commissioned on 10 December 1906. Service history After a shakedown cruise off the coast of California and Mexico, from 14 March through 28 May 1907, ''Milwaukee'' departed San Francisco, California on 26 June 1907 and cruised off the coast of San Salvador and Costa Rica and engaging in target practice with the squadron in Magdalena Bay. On 26 March 1908, the cruiser sailed from San Francisco for Bremerton, Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

6"/50 Caliber Gun
The 6"/50 caliber gun Mark 6 and Mark 8 (spoken "six-inch-fifty-caliber") were used for the secondary batteries of the United States Navy's and battleships, as well as the and armored cruisers. They were also used as the main battery on the protected cruisers. Design The /50 caliber Mark 6 guns were developed around the time of the Spanish–American War. The gun card designates the gun as 46-caliber but the Bureau of Ordnance lists the guns as 50-caliber. The Mark 6 gun was constructed of gun steel using a tube, jacket, four hoops, a locking ring, and Welin breech block. It was discovered that the pressure curve of the charge and the strength curve of the barrel match exactly along one point of the barrel, because of this the muzzle velocity was reduced from the original to . With the Mod 1 nickel-steel was used for the tube, two hoops and the locking ring, the gun was also hooped to the muzzle, because of this, the original muzzle velocity was able to be restored. T ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence airc ...

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during batt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amidships
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water (mostly though not necessarily on the sea). Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin ''nauticus'', from Greek ''nautikos'', from ''nautēs'': "sailor", from ''naus'': "ship". Further information on nautical terminology may also be found at Nautical metaphors in English, and additional military terms are listed in the Multiservice tactical brevity code article. Terms used in other fields associated with bodies of water can be found at Glossary of fishery terms, Glossary of underwater diving terminology, Glossary of rowing terms, and Glossary of meteorology This glossary of meteorology is a list of terms and concepts relevant to meteorology and atmospheric science, their sub-disciplines, and related fields.

Deck (ship)
A deck is a permanent covering over a Compartment (ship), compartment or a hull (watercraft), 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 (physics), tension, Compression (physics), compression, and racking forces. The deck's scantling is usually the same as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 be ...

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. Finla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hotchkiss Gun
The Hotchkiss gun can refer to different products of the Hotchkiss arms company starting in the late 19th century. It usually refers to the 1.65-inch (42 mm) light mountain gun; there were also a navy (47 mm) and a 3-inch (76 mm) Hotchkiss guns. The 42 mm gun was intended to be mounted on a light carriage or packed on two mules to accompany a troop of cavalry or an army travelling in rough country. Descriptions 1.65-inch gun The gun and accessories could be packed on two mules. The gun was introduced as a modern replacement for the aging twelve-pounder mountain howitzer. The first gun purchased by the U.S. military from the French arms firm of Hotchkiss was employed against the Nez Percé in 1877. Over the next twenty years the U.S. purchased 56. They were used at the Wounded Knee Massacre in 1890, and again in Cuba at the Battle of Las Guasimas, the Battle of El Caney and the attack on San Juan Hill during the Spanish–American War of 1898. ...

Gun Salutes
A 21-gun salute is the most commonly recognized of the customary gun salutes that are performed by the firing of cannons or artillery as a military honor. As naval customs evolved, 21 guns came to be fired for heads of state, or in exceptional circumstances for heads of government, with the number decreasing with the rank of the recipient of the honor. While the 21-gun salute is the most commonly recognized, the number of rounds fired in any given salute will vary depending on the conditions. Circumstances affecting these variations include the particular occasion and, in the case of military and state funerals, the branch of service, and rank (or office) of the person to whom honors are being rendered. History The custom stems from naval tradition in the sixteenth century, when a warship entering a foreign port would fire each of its cannons while still out of range of targets. Since cannons then required a considerable time to reload, the ship was effectively disarmed, sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
