21 Cm Mörser 16
The 21 cm Mörser 16 (21 cm Mrs 16), or 21 cm Lange Mörser M 16/L14.5, was a heavy howitzer used by Germany in World War I and World War II (although classified as a mortar (Mörser) by the German military). History It was based on the earlier 21 cm Mörser 10 but had a longer barrel, a gun shield and other refinements. Originally, it broke down into two loads for transport but the Germans rebuilt surviving guns during the 1930s with rubber-rimmed steel wheels to allow for motor traction in one piece with a limber under the trail and generally removed the gun shield. Combat service In German service, it used two shells, the 21 cm Gr 18 ( HE) that weighed and the 21 cm Gr 18 Be concrete-piercing shell of with a filler of of TNT. They remained in first-line use with the Germans until replaced by the 21 cm Mörser 18 by about 1940. Afterwards, they were used for training, although some equipped units in secondary theaters.

Mortar (weapon)
A mortar today is usually a simple, lightweight, man-portable, Muzzleloader, muzzle-loaded cannon, consisting of a Smoothbore, smooth-bore (although some models use a Rifling, rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a Sight (device), sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy Siege, siege artillery. Mortars launch explosive shell (projectile), shells (technically called Bomb, bombs) in high arching Projectile motion, ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventi ...

World War II Artillery Of Germany
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creatio ...

BL 8-inch Howitzer Mk VI – VIII
The BL 8-inch howitzer Marks VI, VII and VIII (6, 7 and 8) were a series of British artillery siege howitzers on mobile carriages of a new design introduced in World War I.Britain used Roman numerals to designate Marks (i.e. models) of ordnance until after World War II. Hence this article refers to the sixth, seventh and eighth models of British BL 8-inch howitzers They were designed by Vickers in Britain and produced by all four British artillery manufacturers but mainly by Armstrong Whitworth, Armstrong and one American company. They were the equivalents of the German 21 cm Morser 16 and in British service were used similarly to the BL 9.2-inch howitzer but were quicker to manufacture and more mobile. They delivered a shell to . They had limited service in the British Army in World War II before being converted to the BL 7.2-inch howitzer, new calibre. They also equipped a small number of Australian and Canadian batteries in World War I and by the US Army in that war. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
220 Mm TR Mle 1915/1916
The Mortier de 220 mm Tir Rapide modèle 1915/1916 Schneider or 220 mm TR mle 1915/1916 was a French howitzer designed and produced during the First World War. A number were still on hand during the Second World War and served in Belgian, French and German service. History Before the First World War, the doctrine of the French Army was geared towards a war of rapid maneuver. Consequently, attention was focused on light mobile field guns such as the Canon de 75 modèle 1897 with little consideration given to heavy artillery. As the Western Front settled into trench warfare, the light field guns that the combatants went to war with were beginning to show their limitations when facing an enemy who was now dug into prepared positions. Indirect fire, interdiction, and counter-battery fire emphasized the importance of long-range heavy artillery. The projectiles from the heaviest howitzer available the 155 mm CTR Mle 1904, were found to be ineffective against deeply d ...

Continuation War
The Continuation War, also known as the Second Soviet–Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union during World War II. It began with a Finnish declaration of war on 25 June 1941 and ended on 19 September 1944 with the Moscow Armistice. The Soviet Union and Finland had previously fought the Winter War from 1939 to 1940, which ended with the Soviet failure to conquer Finland and the Moscow Peace Treaty. Numerous reasons have been proposed for the Finnish decision to invade, with regaining territory lost during the Winter War regarded as the most common. Other justifications for the conflict include Finnish President Risto Ryti's vision of a Greater Finland and Commander-in-Chief Carl Gustaf Emil Mannerheim's desire to annex East Karelia. The following paragraph contains a bundle of cites for the Finnish participation in the siege of Leningrad, which is a commonly debated complex issue in the article (see talk).--> On 22 June 1941 ...

Winter War
The Winter War was a war between the Soviet Union and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from its organization. The Soviets made several demands, including that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasonsprimarily the protection of Leningrad, from the Finnish border. When Finland refused, the Soviets invaded. Most sources conclude that the Soviet Union had intended to conquer all of Finland, and cite the establishment of the Finnish Democratic Republic, puppet Finnish Communist government and the Molotov–Ribbentrop Pact' ...

21 cm Mörser 18
The 21 cm Mörser 18 (21 cm Mrs 18), or 21 cm Mörser M 18/L31, was a German heavy howitzer used in the Second World War by Independent artillery battalions and batteries. A number were also used by coastal artillery units. Design The Mörser 18 was designed to replace the obsolescent World War I-era 21 cm Mörser 16 The 21 cm Mörser 16 (21 cm Mrs 16), or 21 cm Lange Mörser M 16/L14.5, was a heavy howitzer used by Germany in World War I and World War II (although classified as a mortar (Mörser) by the German military). History It was based .... The gun design itself was not significantly different from its predecessor but the carriage was improved considerably. It was one of the first artillery pieces that incorporated a dual-recoil system. The barrel retracted naturally in its cradle, and the entire top carriage—which held the barrel and its cradle—retracted across the body of the carriage as well. This system damped out the recoil ...

Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are sai ...

Limbers And Caissons
A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed. The trail is the hinder end of the stock of a gun-carriage, which rests or slides on the ground when the carriage is unlimbered. A caisson () is a two-wheeled cart designed to carry artillery ammunition; the British term is "ammunition wagon". Caissons are also used to bear the casket of the deceased in some state and military funerals in certain Western cultures, including the United States. Before the 19th century As artillery pieces developed trunnions and were placed on carriages featuring two wheels and a trail, a limber was devised. This was a simple cart with a pintle. When the piece was to be towed, it was raised over the limber and then lowered, with the pintle fitting into a hole in the trail. Horses or other draft animals were harnessed in single file to haul the limber. There was no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Shield
A U.S. Marine manning an M240 machine gun equipped with a gun shield A gun shield is a flat (or sometimes curved) piece of armor designed to be mounted on a crew-served weapon such as a machine gun, automatic grenade launcher, or artillery piece. Military Some mounted machine guns and artillery pieces are equipped with metal armor plates to protect the gunners from small arms fire and shrapnel from explosions. They were fitted to some armored fighting vehicles and patrol boats during the Vietnam War. Gun shields fell out of widespread use after the Vietnam War, but they have seen a resurgence in popularity during the 1980s and 1990s. Israeli military analysts began urging the use of gun shields, pointing to the grave risk to soldiers exposed to fire from automatic weapons. In particular, it was noted that many casualties were hit in areas not protected by body armor or a helmet, such as the neck or face. The United States Armed Forces began using gun shields in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
