105mm Round

105mm rounds in the U.S. military are used by the M1128 Stryker Mobile Gun System vehicles.

M900 Armor Piercing, Fin Stabilized, Discarding Sabot - Tracer

The M900 is a kinetic energy, armor-piercing anti-tank round intended for use with the 105mm, M68 series gun. The complete round contains a propulsion system consisting of an M148A1B1 steel cartridge case, an M43 LOVA propellant, an M128 primer, and a gun tube wear-reducing titanium dioxide liner which is assembled to the interior wall of the cartridge case. The projectile portion of the round consists of a depleted uranium subprojectile and a sabot.

Timeline

1989 - Entered service

M456A2 High Explosive Anti-Tank Multipurpose - Tracer

The M456A2 is a High Explosive Antitank Multipurpose with Tracer (HEAT-MP-T) cartridge for use in the M68, 105mm Cannon of the Stryker Mobile Gun System (MGS). It is designed for use against armored targets and contains Composition B Explosive and a copper shaped charge liner inside a steel body. A point-initiating, point-detonating fuze is initiated by an impact switch in an aluminum standoff spike. Upon initiation, the explosive collapses the copper liner and creates a high velocity jet of metal particles that penetrates the target.

M490A1 Target Practice - Tracer

The M490A1 Target Practice - Tracer (TP-T) Cartridge is for use in the M68 Series Cannon for training in marksmanship. The cartridge is similar in external appearance and ballistically similar to the M456 Series HEAT-T Cartridge. The projectile consists of a steel body and steel standoff spike. It also has no fin assembly and is static stabilized. The cartridge case is filled with loosely packed propellant and is fitted with an electric primer.

Muzzle velocity: 1 170 meters per second 3 840 feet per second

M724A1 Target Practice Discarding Sabot - Tracer

The M724A1 Target Practice Discarding Sabot - Tracer (TPDS-T) Cartridge is similar in external appearance and is ballistically similar out to 2,000 meters with the M392A2 APDS-T cartridge. A plastic band encircles the sabot at the forward end while a fiber rotating band and rubber obturating band are mounted toward the base of the sabot. The igniter tube of the electric primer extends almost the entire length of the propellant, which is packed loosely in the cartridge case. The electrically initiated primer ignites the propelling charge and tracer. Gases produced by the burning propellant propel the projectile from the gun. The sabot is discarded after leaving the muzzle of the weapon as a result of setback, centrifugal, and air pressure forces and the solid core of the projectile continues to the target. Since it is a practice round, the projectile lacks the penetrating capability of a service round.

M1040 Canister

The M1040 Canister Cartridge satisfies the Mobile Gun System's (MGS) primary armament requirement to defeat a dismounted infantry squad approaching in a wedge formation. Upon muzzle exit, the projectile breaks apart and releases over 2000 tungsten spheres, similar to a shotgun shell. The cartridge’s unique design provides effectiveness across temperature extremes.

Characteristics

Features
Range (threshold): 100-300 meters (to provide 50% incapacitation to 5 men of a 10 man squad) 328-984 feet (to provide 50% incapacitation to 5 men of a 10 man squad)
Range (objective): 50-500 meters (to provide 50% incapacitation to 5 men of a 10 man squad) 164-1 640 feet (to provide 50% incapacitation to 5 men of a 10 man squad)

M724A2 Target Practice Discarding Sabot - Tracer

The M724A2 Target Practice Discarding Sabot-Tracer (TPDS-T) Cartridge supports live fire training for the Stryker Mobile Gun System (MGS) crews in the Stryker Brigade Combat Team (SBCT). The cartridge is similar to the 105mm M900 tactical cartridge in weight and physical appearance. The M724A2 is range limited to 7,000 meters maximum when fired at a 10⁰ gun elevation.

M393A3 High Explosive Plastic - Tracer

The M393A3 High Explosive Plastic - Tracer (HEP-T) Cartridge satisfies the Mobile Gun System’s (MGS) primary armament requirement to defeat standard infantry bunkers and create openings in double reinforced concrete walls through which infantry can pass through. It is also effectivew against light armored vehicles, trucks, cars and sniper positions.

M467A1 High Explosive Plastic Target Practice - Tracer

The M467A1 High Explosive Plastic Target Practice - Tracer (HEP-TPT) Cartridge is an inert round of ammunition fitted with a tracer. The cartridge is used in the M68 Series Gun mounted on the Mobile Gun System (MGS) of the Stryker Brigade Combat Team (BCT) in support of gunnery training and qualification. The cartridge is also physically and ballistically matched to the 105mm M393A3 High Explosive Plastic with Tracer (HEP-T) Cartridge.
