XM1128
The M1128 "Insensitive Munition High Explosive Base Burn Projectile" is a boosted artillery round designed to achieve a maximum range of . It is used for fragmentation and blast effect against personnel and/or materiel. The development of this round follows testing of (and is based on aspects of) boosted M795-series test projectiles. The M1128 is not yet in production, but the first successful test firings have already taken place. The M1128 is expected to be compatible with a nose-mounted guidance system—specifically, the XM1156 Precision Guidance Kit, which fits the standard fuse threading common to several types of rounds. Development The design program for the M1128 was established in FY2011 with the stated purpose of addressing USMC requirements for artillery ammunition capable of range. It is also designed for improved accuracy. It carries a larger payload than the aging M549 Extended Range Projectile or ERP, which is the previous boosted round the M1128 is designe ...

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 ...

155 Mm
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] |

M549
The M549 is a high-explosive rocket-assisted (HERA) 155 mm howitzer round developed for use by the US military in order to add additional range to standard howitzers, with a maximum range from a M198 howitzer. The projectile has two distinctive pre-assembled components—the high-explosive (HE) warhead and the rocket motor, making it a form of rocket-assisted projectile. The warhead is fabricated from high-fragmentation steel for increased effectiveness in terms of damage caused to target and contains a bulk-filled explosive (either TNT or Composition B). Development The projectile was developed to provide extended range for standard and developmental howitzers. The projectile has two distinctive preassembled components—the high-explosive warhead and the rocket motor. The warhead is fabricated from high-fragmentation steel for increased effectiveness and contains a bulk-filled explosive. Currently there are two models.

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] |
M114 155 Mm Howitzer
The 155 mm Howitzer M114 is a towed howitzer developed and used by the United States Army. It was first produced in 1941 as a medium artillery piece under the designation of 155 mm Howitzer M1. It saw service with the US Army during World War II, the Korean War, and the Vietnam War, before being replaced by the M198 howitzer. The gun was also used by the armed forces of many nations. The M114A1 remains in service in some countries. Development Early development After the end of the First World War a board later named the Westervelt Board after its president, Brigadier General William I. Westervelt, was convened to assess the artillery experience of the combatant powers and map out future directions for the US Army artillery. The conclusion of the board vis-a-vis corps (heavy field) artillery was that an ideal heavy howitzer should have range of at least and allow the elevation of 65°B. P.

Circular Error Probable
Circular error probable (CEP),Circular Error Probable (CEP), Air Force Operational Test and Evaluation Center Technical Paper 6, Ver 2, July 1987, p. 1 also circular error probability or circle of equal probability, is a measure of a weapon system's Accuracy and precision, precision in the military science of ballistics. It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the Round (firearms), rounds; said otherwise, it is the median error radius, which is a 50% confidence interval. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, an average of 50 will fall within a circle with a radius of 100 m about that point. There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, a form of the standard deviation. Another is the R95, which is the radius of the circle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
