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 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.
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.
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.
The 2K25 Krasnopol [12] [13] [14] 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.
The M77 was developed from the M483A1 that was developed for so-called "cargo" artillery shells in the 155 mm and 8-inch (203 mm) calibers. 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 ...
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.
It had a 155 mm autocannon with an exceptionally high rate of fire, being able to fire 15 shells in 45 seconds with one round preloaded and full magazine of two rows of seven rounds in a clip. [3] The magazine could then be reloaded with a built-in hoist in about 2 minutes. Each shell had a weight of 47 kg and a tactical range of 28 km.
