M107 Projectile
The M107 is a 155 mm high explosive projectile used by many countries. It is a bursting round with fragmentation and blast effects. It used to be the standard 155 mm high explosive projectile for howitzers of the US Army and US Marine Corps, but is being superseded in the US military by the M795. Development The M107 is a development of the M102 155 mm shell that was developed in the 1930s from the French Schneider 155 mm projectile for the Model 1917 Howitzer. Description The body consists of a hollow steel shell containing high explosive (either TNT or Composition B) painted olive drab with yellow markings. A fuze adapter is screwed into the body and brazed in place. An eyebolt lifting plug is screwed into the fuze well to assist in transportation. The plug is removed and replaced with a fuze for firing. The complete projectile weighs , is long and contains 15.8% explosive by weight. It is a separate-loading projectile—propellant bags or modular arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates its function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the deton ...

Canon De 155 C Modèle 1917 Schneider
The Canon de 155 C modèle 1917 Schneider (or Canon de 155 C Mle 1917 Schneider), often abbreviated as the ''C17S'', was a French howitzer designed by Schneider-Creusot, Schneider. It was essentially the ''Canon de 155 C modèle 1915 Schneider'' fitted with a different breech to use bagged propellant rather than the cartridge cases used by the older howitzer. It was used by France, Russian Empire, Belgium, Romania, and the United States from 1917 during World War I and was widely exported after the war. Surviving weapons were in service with France, Poland, Greece, Italy, Belgium, the United States, and Finland during World War II. Captured weapons were used by the Wehrmacht, Germans for their 2nd-line artillery and coast defense units. Development and description Canon de 155 C modèle 1915 Schneider The ''Canon de 155 C modèle 1915'' was based on Schneider's 152 mm howitzer M1910, M1910 howitzer that had been sold to the Russian Empire. Schneider later used the M1910 carriage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
155 Mm Artillery
Year 155 ( CLV) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Rufinus (or, less frequently, year 908 ''Ab urbe condita''). The denomination 155 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events * The Council of Rome, a pre-ecumenical church council, is held and presided over by Bishop of Rome Anicetus.

List Of Crew Served Weapons Of The US Armed Forces
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

List Of Artillery
Artillery has been one of primary weapons of war since before the Napoleonic Era. Several countries have developed and built artillery systems, while artillery itself has been continually improved and redesigned to meet the evolving needs of the battlefield. This has led to a multitude of different types and designs which have played a role in the history of warfare and continue to be a significant factor in modern combat. For the most part, the following lists of artillery cover guns, howitzers, mortars, and other large projectile weapons. Small arms and missiles are not generally included, though rockets and other bombardment A bombardment is an attack by artillery fire or by dropping bombs from aircraft on fortifications, combatants, or cities and buildings. Prior to World War I, the term was only applied to the bombardment of defenseless or undefended obje ... weapons may be.

Base Bleed
Base bleed or base burn (BB) is a system used on some artillery shells to increase range, typically by about 20%–35%. It expels gas into the low-pressure area behind the shell to reduce Drag (physics), base drag (but does not produce thrust, unlike rocket-assisted projectile, rocket-assisted projectiles). Being percentage-based, the range extension is more useful on longer-range artillery where an increase of approximately can be achieved, and it also was found that the reduced turbulence gave the projectiles a more consistent trajectory, resulting in tighter grouping, and efficient shelling more than away. Base bleed technology was developed in Sweden in the mid-1960s but took some time to spread and find its niche between cheaper classical ordnance and even more expensive rocket-assisted projectiles. It is now a fairly common option. Function Most (50–60%) of the drag (physics), drag on an artillery shell derives from the nose portion of the shell. Artillery shells ...

M198 Howitzer
The M198 is a medium-sized, towed 155 mm artillery piece, developed for service with the United States Army and Marine Corps. It was commissioned to be a replacement for the World War II-era M114 155 mm howitzer. It was designed and prototyped at the Rock Island Arsenal in 1969 with firing tests beginning in 1970 and went into full production there in 1978. It entered service in 1979 and since then 1,600 units have been produced. The M198 was replaced in US and Australian service by the M777 howitzer. Description The M198 155 mm howitzer weighs less than , allowing it to be dropped by parachute or transported by a CH-53E Super Stallion or CH-47 Chinook. The M198 is towed by a truck that is used to carry the nine person crew with supplies and ammunition; it is transported tail first. The gun tube can be rotated over the howitzer's trail legs to reduce its length, though this requires removal of the muzzle brake, or left in the firing position for faster deployment. When f ...

Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or another motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel a ...

Shell (projectile)
A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary device, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer ammunition, tracer. All explosive- and incendiary-filled projectiles, particularly for mortar (weapon), mortars, were originally called ''grenades'', derived from the French language, 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 vehicle, armoured fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape is usually a cylinder (geometry), cylinder topped by an o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M795
The M795 155 mm projectile is the US Army and US Marine Corps' standard 155 mm High Explosive (HE) projectile for howitzers. It is a bursting round with fragmentation and blast effects. The M795 is designed to be more lethal and have a longer range than that of the M107. A welded band replaces the swaged rotating band of the M107, allowing the M795 to be fired with M119 or M203 propelling charges, increasing range by . The explosive payload was improved, as was the fragmentation pattern, giving 30% higher lethality. Description The M795 is a 155 mm high- fragmentation, steel (HF1)-body projectile, filled with of TNT. It weighs approximately . The high-fragmentation steel body is encircled by a gilding metal rotating band, making it compatible with 3W through 8S (M3A1 through M203A1) zone propelling charges across all current 155 mm howitzers. The projectile is packaged on a metal pallet, with a shock-attenuating lifting plug and flexible rotating band cover. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
155 Mm Caliber
The 155 mm calibre is widely used for artillery guns. Land warfare Historic calibres France - 1874 The caliber originated in France after the Franco-Prussian War (1870–1871). A French artillery committee met on 2 February 1874 to discuss new models for French fortress and siege artillery, among which there was a weapon in the calibre range. After several meetings, on 16 April 1874 the committee settled on the calibre, and led to the De Bange 155 mm cannon. NATO standard Among the existing and the former 155 mm artillery shells, there is one that has been standardised by NATO under both the AOP-29 part 1 (in reference to STANAG 4425), and under the (Joint Ballistics Memorandum of Understanding). This standard defines a standard 155mm projectile with a 23 litre combustion chamber volume. NATO is now pushing from standardised artillery shell to sharable ammunition. The standard described above enables the use of NATO shells in all NATO guns. But they still need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
