Battleship Secondary Armament
Secondary armaments are smaller, faster-firing weapons that are typically effective at a shorter range than the main (heavy) weapons on military systems, including battleship- and cruiser-type warships, tanks/armored personnel carriers, and rarely other systems. The nature, disposition, size and purpose of Naval secondary weapon systems changed dramatically as the threat changed from torpedo boats, to torpedo-carrying destroyers, to aircraft, to anti-ship missiles. Naval Pre-dreadnought era Pre-dreadnoughts, from the period 1890 to 1905, were typically fitted with 3 or 4 different calibres of weapon. The main guns were usually approximately 12-inch caliber, secondary weapons usually 6-inch but typically in the range 5-inch to 7.5-inch. Guns smaller than 4.7-inch are usually considered "tertiary". (Many pre-dreadnoughts also carried 9.2 to 10-inch "secondary" guns, but they are usually treated instead as a mixed-caliber main armament.) Secondary guns were "quick firers ...

Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close-in Weapon System
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examples of ...

Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a naval gun or group of guns used in volleys, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles and torpedoes as a warship's principal offensive weaponry, deployed both on surface ships and submarines. A main battery features common parts, munition and fire control system across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and belo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Inch Turrets Aboard USS Massachusetts (BB-59)
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. Humans, and many other animals, have 5 digits on their limbs. Mathematics 5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple ( 3, 4, 5). 5 is the first safe prime and the first good prime. 11 forms the first pair of sexy primes with 5. 5 is the second Fermat prime, of a total of five known Fermat primes. 5 is also the first of three known Wilson primes (5, 13, 563).

Battle Of Jutland
The Battle of Jutland () was a naval battle between Britain's Royal Navy Grand Fleet, under Admiral John Jellicoe, 1st Earl Jellicoe, Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War. The battle unfolded in extensive manoeuvring and three main engagements from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. It was the largest naval battle and only full-scale clash of battleships of the war, and the outcome ensured that the Royal Navy denied the German surface fleet access to the North Sea and the Atlantic for the remainder of the war. Germany avoided all fleet-to-fleet contact thereafter. Jutland was also the last major naval battle, in any war, fought primarily by battleships. Germany's High Seas Fleet intended to lure out, trap, and destroy a portion of the British Grand Fleet. The German naval force was insufficient to openly engage the British fleet. This was par ...

Magazine (artillery)
A magazine is an item or place within which ammunition or other explosive material is stored. The word is taken originally from the Arabic word ''makhāzin'' (مخازن), meaning "storehouses", via Italian and Middle French. The term is also used for an ammunition dump, a place where large quantities of ammunition are stored for later distribution. This usage is less common. Field magazines In the early history of tube artillery drawn by horses (and later by mechanized vehicles), ammunition was carried in separate unarmored wagons or vehicles. These soft-skinned vehicles were extremely vulnerable to enemy fire and to explosions caused by a weapons malfunction. Therefore, as part of setting up an artillery battery, a designated place would be used to shelter the ready ammunition. In the case of batteries of towed artillery the temporary magazine would be placed, if possible, in a pit, or natural declivity, or surrounded by sandbags or earthworks. Circumstances might requ ...

Danton-class Battleship
The ''Danton''-class battleship was a class of six semi-dreadnought battleships built for the French Navy (''Marine Nationale'') before World War I. The ships were assigned to the Mediterranean Fleet after commissioning in 1911. After the beginning of World War I in early August 1914, five of the sister ships participated in the Battle of Antivari. They spent most of the rest of the war blockading the Straits of Otranto and the Dardanelles to prevent warships of the Central Powers from breaking out into the Mediterranean. One ship was sunk by a German submarine in 1917. The remaining five ships were obsolescent by the end of the war and most were assigned to secondary roles. Two of the sisters were sent to the Black Sea to support the Whites during the Russian Civil War. One ship ran aground and the crew of the other mutinied after one of its members was killed during a protest against intervention in support of the Whites. Both ships were quickly condemned and later sold f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Duke-class Battleship
The ''Iron Duke'' class was a group of four dreadnought battleships built for the British Royal Navy before the First World War. The class comprised four ships: , , , and . Launched from October 1912 to November 1913, this was the third class of Royal Navy super-dreadnoughts. The ships were essentially repeats of the battleships; they retained the same ten 13.5 inch (34.3 cm) guns in five twin gun turrets on the centreline. However, the ''Iron Duke''s had improved armour and a more powerful secondary armament of 6-inch weapons instead of the 4-inch mounted on the earlier ships. The four ships were the most advanced battleships in the Royal Navy at the outbreak of the First World War, though they were soon surpassed by the five ships of the . They all saw extensive service during the war with the Grand Fleet, where ''Iron Duke'' acted as the flagship for the fleet commander, Admiral John Jellicoe, 1st Earl Jellicoe, John Jellicoe. Three of the ships, ''Iron Duke'', ''B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreadnought
The dreadnought was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's , had such an effect when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany. Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Within five years, new battleships outclassed ''Dreadnought'' herself. These more powerful vessels were know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
