Mobile Gun System (MGS)
Through a contract agreement with our parent company, General Dynamics Land Systems, GDRS has been tasked to develop, design, manufacture, assemble, and test the Ammunition Handling System (AHS) of the Mobile Gun System (MGS) Stryker variant.
The MGS variant carries a General Dynamics 105mm tank cannon in a low-profile, fully stabilized “shoot on the move” turret. Its armor protects the three-soldier crew from machine gun bullets, mortar, and artillery fragments on the battlefield. The Stryker Mobile Gun System can fire 18 rounds of 105-mm main gun ammunition; 400 rounds of .50 caliber ammunition; and 3,400 rounds of 7.62-mm ammunition. It operates with the latest C4ISR equipment as well as detectors for nuclear, biological and chemical weapons.
The MGS will employ four types of 105mm tactical ammunition. High explosive/high explosive plastic (HE/HEP) ammunition will destroy hardened enemy bunkers, machinegun and sniper positions, and create openings in walls through which infantry can pass. Kinetic energy (KE) ammunition will be employed to destroy a variety of Level II armored vehicles. High explosive, anti-tank (HEAT) ammunition is well suited to defeat a variety of thin-skinned vehicles and provide fragmentation effects. Finally, anti-personnel (canister) ammunition will defeat attacking dismounted infantry in the open. HE/HEP, KE and HEAT each have or will have complementary training ammunition.
The AHS enables the MGS gunner to select any type round at the touch of a button while maintaining a rate of fire of 6 rounds per minute. The AHS consists of three Line Replaceable Units (LRU’s): the Carousel and Rammer, which are mounted in the turret and spin with the main gun, and the Replenisher, which is mounted in the lower hull and feeds the Carousel when the main gun is at 0 degree azimuth.
