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.
A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines.
A flechette is a pointed, fin-stabilized steel projectile. The name comes from French fléchette, meaning "little arrow" or "dart", and sometimes retains the acute accent in English: fléchette. They have been used as ballistic weapons since World War I. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial.
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge. The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor.
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. A shell can hold a tracer.
The M270 Multiple Launch Rocket System is an American armored self-propelled multiple launch rocket system.
The M982 Excalibur is a 155 mm extended-range guided artillery shell developed in a collaborative effort between the U.S. Army Research Laboratory (ARL) and the United States Army Armament Research, Development and Engineering Center (ARDEC). The Excalibur was developed and/or manufactured by prime contractor Raytheon Missiles & Defense, BAE Systems AB and other subs and primes in multiple capacities such as Camber Corporation and Huntington Ingalls Industries. It is a GPS and inertial-guided munition capable of being used in close support situations within 75–150 meters (250–490 ft) of friendly troops or in situations where targets might be prohibitively close to civilians to attack with conventional unguided artillery fire. In 2015, the United States planned to procure 7,474 rounds with a FY 2015 total program cost of US$1.9341 billion at an average cost of US$258,777 per unit. By 2016, unit costs were reduced to US$68,000 per round. Versions that add laser-guidance capability and are designed to be fired from naval guns began testing in 2015. By October 2018, over 1,400 rounds had been fired in combat.
Project Sense and Destroy Armor, or SADARM, is a United States 'smart' submunition capable of searching for, and destroying tanks within a given target area.
The 2S4 Tyulpan is a Soviet 240 mm self-propelled heavy mortar. "2S4" is its GRAU designation. The Tyulpan is the largest mortar system in use today.
The M864 is an American made 155 mm artillery shell. It carries a DPICM warhead and incorporates base bleed technology to increase its range. The projectile is capable of delivering 24 M46 and 48 M42 dual-purpose anti-materiel/anti-personnel sub-munitions at ranges out to 29 kilometers. Base bleed technology was developed to reduce the amount of base drag on a projectile, thereby increasing the achieved range. The drag is reduced by a gas generator located on the base of the projectile. Once ignited, the gas generator bleeds hot gas into the projectile's wake, which causes the flow of air at the base to be less turbulent. The decrease in turbulence reduces base drag, which typically accounts for 50 percent of total drag. The amount of thrust produced by the base burner unit is negligible and does not serve the same function as the rocket motor on a rocket-assisted projectile (RAP).
The Extended Range Guided Munition was a precision guided rocket-assisted 5-inch (127 mm) shell (projectile) development by Raytheon for the U.S. Navy. The program was cancelled in March 2008 after twelve years of development and over 600 million dollars in funding. The developmental round was designated EX 171.
The 2K25 Krasnopol is a Soviet 152/155 mm cannon-launched, fin-stabilized, base bleed-assisted, semi-automatic laser-guided artillery weapon system. It automatically 'homes' on a point illuminated by a laser designator, typically operated by a drone or ground-based artillery observer. Krasnopol projectiles are fired mainly from Soviet self-propelled howitzers such as the 2S3 Akatsiya and 2S19 Msta-S and are intended to engage small ground targets such as tanks, other direct fire weapons, strong-points, or other significant point targets visible to the observer. It can be used against both stationary and moving targets.
Ammunition is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons and the component parts of other weapons that create the effect on a target.
A precision-guided munition is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
155 mm is a NATO-standard artillery shell caliber that is used in many field guns, howitzers, and gun-howitzers. It is defined in AOP-29 part 1 with reference to STANAG 4425.
The SMArt 155 is a German 155 mm artillery round designed for a long-range, indirect fire top-attack role against armoured vehicles. The projectile was developed in 1989 by Diehl BGT Defence in Überlingen, Germany, with Rheinmetall and started full-rate production for the German Army in 1998. It consists of a 47-kilogram (104 lb) heavy artillery projectile containing two autonomous, sensor-fused, "fire-and-forget" submunitions. Due to the submunitions, it has been considered by some to be a cluster munition. As of 2008, representatives of the German defense ministry have referred to it as not being classified as submunition weapons, which were prohibited by the 2008 Convention on Cluster Munitions.
The Soviet 240 mm mortar M240 is a 240 millimeter breech loading smoothbore heavy mortar that fires a 130 kilogram projectile. It entered service in 1953.
The BONUS or ACED is a 155 mm artillery cluster round co-developed and manufactured by Bofors of Sweden and Nexter of France. It was designed to fulfill a long range, indirect fire, top attack requirement against armoured fighting vehicles.
The most significant using of incendiary weapons were used a number of times during the Russo-Ukrainian War. Russians were accused of using white phosphorus bombs multiple times; in the Battle of Kyiv and against Kramatorsk in March 2022, against dug-in defenders at the Azovstal steel plant in Mariupol in May 2022, and in Marinka over the 2022 Christmas holiday. White phosphorus is a toxic chemical, and exposure to vapors leads to long-term ailments of the body, up to permanent disfigurement and death through organ failure.
The use of cluster munitions during the Russian invasion of Ukraine (2022–present) has been recorded by a number of eyewitnesses and journalists, as well as representatives of the UN, humanitarian and public organizations. In particular, the head of the UN Human Rights Council, Michelle Bachelet, reported on March 30 at least 24 cases since the beginning of the invasion. As of July 1, hundreds of attacks by Russian forces with cluster munitions have already been recorded in the settlements of the Dnipropetrovsk, Donetsk, Zaporizhzhia, Kyiv, Luhansk, Mykolaiv, Odesa, Sumy, Kharkiv, Kherson and Chernihiv regions. 215 civilians are known to have been killed in these shellings and 474 injured, many of which may go unreported. Both Russia as well as Ukraine have used cluster munitions during the conflict, however, Russian use has been extensive while Ukrainian use has been more limited.
