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.
M712 Copperhead approaches an old M47 Patton tank used as a target M712 detonating. The M712 Copperhead is a 155 mm caliber cannon-launched guided projectile.It is a fin-stabilized, terminally laser guided, explosive shell intended to engage hard point targets such as tanks, self-propelled howitzers or other high-value targets.
The Army bought 5,480 mortar guidance kits in response to an operational needs statement in Afghanistan, sometimes hitting as close as 2.2 meters from the target. With the success of the XM395, the Army is seeking a guided 120 mm mortar Program of Record with comparable accuracy through the High Explosive Guided Mortar (HEGM) proposal.
A lower cost alternative to the Excalibur is to use the US Army designed M1156 Precision Guidance Kit to turn existing 155 mm shells into precision weapons. [19] The munition was co-developed by United States-based Raytheon Missiles & Defense (guidance system) and the Swedish BAE Systems Bofors (body, base, ballistics, and payload). [11]
The PGK is compatible with various 155 mm artillery stockpiles to reduce dispersion. It was demonstrated on German DM111 shells in September 2014 fired from a PzH2000 self-propelled howitzer. From a distance of 27 km (17 mi), 90 percent of the PGK-equipped German shells landed within 5 meters of the target.
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.
The 155 mm M549/M549A1 HERA is a separate-loading munition with a two-part forged shell body. The forward HE-filled shell body is constructed from high-fragmentation steel (HF1) and is of a low-drag aerodynamic profile. The rocket-motor body makes up the rear of the shell, this constructed from 4340 steel.
The BONUS (Bofors Nutating Shell) [2] or ACED (Anti-Char à Effet Dirigé) [3] [4] [5] 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.
