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] |

IMX-101
IMX-101 is a high-performance insensitive high explosive composite mixture developed by BAE Systems and the United States Army to replace TNT in artillery shells. IMX stands for "Insensitive Munitions eXplosives", which refers to the purpose of IMX-101: to provide explosive force equivalent to TNT without its sensitivity to shocks such as gunfire, explosions from improvised explosive devices, fire, and shrapnel. For example, it is believed that a training incident in Nevada which killed seven Marines would not have occurred with the new explosive. On March 23, 2013, the United States Army ordered $780 million worth of the explosive, with a production of millions of pounds annually, to be produced by BAE at Holston Army Ammunition Plant in Tennessee. The new explosive will cost $8 per pound, compared to $6 per pound for TNT. As of 2023, IMX-101 filled shells are being used in the 2022 Russian invasion of Ukraine. ''Time Magazine'' called IMX-101 one of the "50 best inventions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

Dual-Purpose Improved Conventional Munition
A dual-purpose improved conventional munition (DPICM) is an artillery or surface-to-surface missile warhead designed to burst into submunitions at an optimum altitude and distance from the desired target for dense area coverage. The submunitions use both shaped charges for the anti-armor role, and fragmentation for the antipersonnel role, hence the nomenclature "dual-purpose". Some submunitions may be designed for delayed reaction or mobility denial ( mines). The air-to-surface variety of this kind of munition is better known as a cluster bomb. They are banned by more than 100 countries under the Convention on Cluster Munitions. United States DPICM projectiles Development work for DPICM projectiles began in the late 1950s. The first projectile, the 105 mm M444, entered service in 1961. Its submunitions were simple bounding anti-personnel grenades (ICM). Production of the M444 ended in the early 1990s. The first true DPICM was the 155 mm M483, produced in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M109 Howitzer
The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44 and M52. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. It has a crew of four: the section chief/commander, the driver, the gunner, and the ammunition handler/loader. The British Army replaced its M109s with the AS-90. Several European armed forces have or are currently replacing older M109s with the German PzH 2000. Upgrades to the M109 were introduced by the U.S. (see variants) and by Switzerland (KAWEST). With the cancellation of the U.S. Crusader, non-line-of-sight cannon and M1299 the M109A6 ("Paladin") will likely remain the principal self-propelled howitzer for the U.S. until a replacement enters service.

Course Correcting Fuze
An artillery fuze or fuse is the type of munition fuze used with artillery munitions, typically projectiles fired by guns (field, anti-aircraft, coast and naval), howitzers and Mortar (weapon), mortars. A fuze is a device that initiates an explosive function in a munition, most commonly causing it to detonate or release its contents, when its activation conditions are met. This action typically occurs a preset time after firing (time bomb, time fuze), or on physical contact with (contact fuse, contact fuze) or detected proximity to the ground, a structure or other target (proximity fuze). Fuze, a variant of fuse, is the official NATO spelling. Terminology Munitions fuzes are also used with rockets, aircraft bombs, guided missiles, grenades and mines, and some direct fire cannon munitions (small calibre and tank guns). Broadly, fuzes function on impact (percussion fuzes) or at a pre-determined time period after firing (time fuzes). However, by the 18th century time fuzes were a ...
