The 155 mm (6.1 in) 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 14–16 cm (5.5–6.3 in) caliber range (later it became known as the De Bange 155 mm cannon). After several meetings, on 16 April 1874 the committee settled on the 155 mm (6.1 in) caliber (in the subsequent program-letter of the committee, dating from 21 April 1874, the caliber was for the first time expressed as 155 mm (6.1 in)).
Since the early 21st century, most NATO armies have adopted 155 mm (6.1 in) weapons as an all-purpose standard. They are seen as striking a good compromise between range and power, while using just a single caliber greatly simplifies the logistics burden. This has led to the obsolescence of larger caliber artillery shells such as the 175 and 203 mm (6.9 and 8.0 in). Some militaries continue to retain the smaller 105 mm (4.1 in) weapons for their light weight and greater portability. Russia and former Eastern Bloc countries tend to use 122, 130, and 152 mm (4.8, 5.1, and 6.0 in) artillery in similar roles.
Since the end of World War II, the 155 mm (6.1 in) caliber has not found any use among naval forces despite its ubiquity on land with most NATO and aligned navies using 76 mm (3.0 in), 100 mm (3.9 in), 114 mm (4.5 in), or 127 mm (5.0 in) guns on modern warships. At one point the British Ministry of Defence studied "up-gunning" the Royal Navy's 4.5 inch Mark 8 naval guns to give increased firepower and a common caliber between the Royal Navy and the British Army. Despite superficially appearing to be inferior based on a simple comparison of round diameters, when firing conventional ammunition the smaller, 4.5 inch Mark 8 naval gun is comparable to the standard 155 mm (6.1 in) gun-howitzer of the British Army. The standard shell from a 4.5 inch Mark 8 naval gun has the same, if not better, range. Only by using rocket-assisted projectiles (RAPs) can most 155 mm (6.1 in) guns have comparable range to the 4.5 inch Mark 8 naval gun and by doing so there is a reduction in the payload. This is because naval guns can be built much more strongly than land-based self-propelled gun-howitzers, and have much longer barrels in relation to caliber (for example the 4.5 inch Mark 8 naval gun has a barrel length of 55 calibers, while the standard AS-90 self-propelled gun has a barrel length of 39 calibers). This allows naval guns to fire heavier shells in comparison to shell diameter and to use larger propellant charges in relation to shell weight, leading to greater projectile velocities. Even without active cooling, the heavier naval gun barrels allow a faster sustained rate of fire than field guns, and this is exploited with an autoloading system with a capacity of several hundred rounds. The 155 mm (6.1 in) is better than the 4.5 inch Mark 8 naval gun for firing cannon-launched guided projectiles (CLGP) as the lower velocity of the 155 mm (6.1 in) shell makes it much easier for the projectiles' internal electronic guidance systems to survive being fired.
While the US Navy's Advanced Gun System (AGS) also uses a 155 mm (6.1 in) caliber, it is not compatible with NATO-standard 155 mm (6.1 in) ammunition. Only one type of ammunition was ever developed and procurement was discontinued in 2016 due to its high cost, making the AGS unusable. [1]

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 AS-90, known officially as Gun Equipment 155 mm L131, is an armoured self-propelled artillery used by the British Army.
Nuclear artillery is a subset of limited-yield tactical nuclear weapons, in particular those weapons that are launched from the ground at battlefield targets. Nuclear artillery is commonly associated with shells delivered by a cannon, but in a technical sense short-range artillery rockets or tactical ballistic missiles are also included.
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships.
The M114 is a towed howitzer developed and used by the United States Army. It was first produced in 1942 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 FH70 is a towed howitzer used by several nations.
The L118 light gun is a 105 mm towed howitzer. It was originally designed and produced in the United Kingdom for the British Army in the 1970s. It has since been widely exported. The L119 and the United States Army's M119 are variants that use a different type of ammunition.
The Advanced Gun System (AGS) is a naval artillery system developed and produced by BAE Systems Armaments & Services for the Zumwalt-class destroyer of the United States Navy. Designated the 155 mm/62 (6.1-inch) Mark 51 Advanced Gun System (AGS), it was designed to provide long-range naval gunfire support against shore-based targets. A total of six of the systems were installed, two on each of the three Zumwalt-class ships. The Navy has no plans for additional Zumwalt-class ships, and no plans to deploy AGS on any other ship. AGS can only use ammunition designed specifically for the system. Only one ammunition type was designed, and the Navy halted its procurement in November 2016 due to cost, so the AGS has no ammunition and cannot be used. The Navy planned to remove the AGS from the ships starting in 2023.
NORA M-84 is a Yugoslav and Serbian 152 mm and 155 mm gun-howitzer developed by the Military Technical Institute (MTI) for the Yugoslav People's Army, Serbian Army, and export. Gun howitzer NORA has three basic versions, and is usually towed by a FAP 2026 BS/AV truck.
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 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.
The 4.5 inch gun M1 was a field gun developed in the United States in the beginning of World War II. It shared the same carriage with the 155mm howitzer M1 and fired the same ammunition as the British BL 4.5-inch medium field gun. Beginning in 1944, the weapon was used by the U.S. Army as corps-level artillery; with the end of hostilities, it was declared obsolete.
The PLZ-05 or the Type 05 is a 155 mm self-propelled howitzer developed by the People's Liberation Army of China to replace the Type 59-1 130 mm towed gun and Type 83 152 mm self-propelled gun. The PLZ-05 was officially unveiled at the Military Museum of the Chinese People's Revolution to mark the 80th anniversary of the PLA in July 2007, and first entered service with the PLA in 2008.
The Panter howitzer is an artillery weapon developed by MKEK for the Turkish Land Forces Command. It has a 155 mm/52-calibre towed howitzer gun and is able to fire NATO projectiles to a maximum range of 40 kilometers using extended-range ammunition. Mounted on the forward part of the carriage is an Auxiliary Power Unit (APU) that enables the Panter to propel itself at a maximum speed of 20 km/h on asphalt road.
The M992 Field Artillery Ammunition Supply Vehicle (FAASV) is built on the chassis of the M109 howitzer. It is also colloquially referred to as a "cat". It replaced the M548 supply vehicle. Unlike the M548, it is armored.
The SMArt 155 is a German 155 mm guided 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.
Cannon-launched guided projectiles (CLGP) are precision-guided munitions launched by howitzers, mortars, tank guns, and naval guns. Those projectile main propulsion system is the initial kinetic shoot, directed as much as possible toward the target. A secondary GPS or geocoordinates-based system then corrects the trajectory to increase target accuracy and fall closer to the target. This system relies on electronic guidance and pre-programmed coordinates, submitted to the round before its launch.
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 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 30.1 km (18.7 mi) 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.
The BONUS or ACED is a 155 mm guided 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.
