Mortier De 370 Modèle 1914 Filloux
The Mortier de 370 modèle 1914 Filloux (MLE) was a siege mortar. It was designed before the First world war and was used during the First world war. History Although the majority of combatants had heavy field artillery prior to the outbreak of WWI, none had adequate numbers of heavy guns in service, nor had they foreseen the growing importance of heavy artillery once the Western Front stagnated and trench warfare set in. Since aircraft of the period could not carry large bombs, the burden of delivering heavy firepower fell on the artillery. Two sources of heavy artillery suitable for conversion to field use were surplus coastal defense guns and naval guns. However, a paradox faced artillery designers; while large-caliber naval guns were common, large-caliber land weapons were not due to their weight, complexity and lack of mobility. Large-caliber field guns often required extensive site preparation because the guns had to be disassembled into multiple loads light enough to b ...

Naval Guns
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

Trunnion
A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion. In mechanical engineering (see the trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. As they allowed the muzzle to be raised and lowered easily, the integral casting of trunnions is seen by military historians as one of the most important advances in early field artillery. With the creation of larger and more powerful siege guns in the early 15th century, a n ... [...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 belt ...

Shell (projectile)
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape ...

Interrupted Screw
Breech from Russian 122 mm M1910 howitzer, modified and combined with 105 mm H37 howitzer barrel An interrupted screw or interrupted thread is a mechanical device typically used in the breech of artillery guns. It is believed to have been invented in 1845. The system has also been used to close other applications, including the joint between helmet (bonnet) and breastplate (corselet) of standard diving suit helmets, and the locks of diving chambers. Design An interrupted screw has a section of thread along its axis removed. The screw is mated with a partially threaded hole in the receptacle: threadless channels in the breechblock screw line up with the threaded parts of the screw, and vice versa. The screw can thus be smoothly inserted all the way into the receptacle, after which as little as one-eighth of a turn can engage the two sets of threads securely, sealing the joint. The amount of rotation required to achieve full closure depends on the number of unthread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Built-up Gun
A built-up gun is artillery with a specially reinforced barrel. An inner tube of metal stretches within its elastic limit under the pressure of confined powder gases to transmit stress to outer cylinders that are under tension.Fairfield (1921) p.161 Concentric metal cylinders or wire windings are assembled to minimize the weight required to resist the pressure of powder gases pushing a projectile out of the barrel. Built-up construction was the norm for guns mounted aboard 20th century dreadnoughts and contemporary railway guns, coastal artillery, and siege guns through World War II. Background The first built-up gun was designed by French artillery officer Alfred Thiéry in 1834 and tested not later than 1840. Also about 1840 another one was made by Daniel Treadwell, and yet another one was produced by Mersey Iron Works in Liverpool according to the John Ericsson's design. Sheffield architector John Frith received a patent on their manufacture in 1843. However, all these guns (w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siegfried Line
The Siegfried Line, known in German as the ''Westwall'', was a German defensive line built during the 1930s (started 1936) opposite the French Maginot Line. It stretched more than ; from Kleve on the border with the Netherlands, along the western border of Nazi Germany, to the town of Weil am Rhein on the border with Switzerland – and featured more than 18,000 bunkers, tunnels and tank traps. From September 1944 to March 1945 the Siegfried Line was subjected to a large-scale Allied offensive. Name The official name for the German defensive line construction program before and during the Second World War that collectively came to be known as the "Westwall" (and "Siegfried Line", or sometimes "West Wall", in English) changed several times during the late 1930s reflecting areas of progress. * Border Watch programme (pioneering programme) for the most advanced positions (1938) * Limes Programme (1938) * Western Air Defense Zone (1938) * Aachen–Saar Programme (1939) * Ge ...

Second Battle Of Champagne
The Second Battle of Champagne ( or Autumn Battle) in World War I was a French offensive against the German army at Champagne that coincided with an Anglo-French assault at north-east Artois and ended with French retreat. Battle On 25 September 1915, twenty divisions of the Second Army and Fourth Army of (GAC, Central Army Group), attacked at with each division on a front. A second line of seven divisions followed, with one infantry division and six cavalry divisions in reserve. Six German divisions held the line opposite, in a front position and the (, Reserve Position) further back. French artillery observers benefited from good weather but on the night of 24/25 September, heavy rain began and fell until midday. The German front position was broken in four places and two of the penetrations reached as far as the , where uncut barbed wire prevented the French from advancing further. In one part of the line, the French artillery barrage continued after the first German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Somme
The Battle of the Somme ( French: Bataille de la Somme), also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and French Third Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the Somme, a river in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle of whom one million were wounded or killed, making it one of the deadliest battles in human history. The French and British had committed themselves to an offensive on the Somme during the Chantilly Conference in December 1915. The Allies agreed upon a strategy of combined offensives against the Central Powers in 1916 by the French, Russian, British and Italian armies, with the Somme offensive as the Franco-British contribution. Initial plans called for the French army to undertake the main part of the Somme offensive, supported on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
