During a live firing demonstration, the Northrop Grumman M230LF 30mm Chain Gun mounted on the EMAV-LW30 UGV (Unmanned Ground Vehicle) has fired Northrop Grumman’s suite of advanced ammunition, including the XM1211 High Explosive Proximity-fuzed round and the XM1198 High Explosive Dual Purpose, Self-Destruct round defeating light ground targets.
Northrop Grumman is a leading producer of a complete family of 30mm tactical and target practice ammunition that is accurate and lethal in anti-armor, anti-material, anti-personnel, ground suppression, air defense and shipboard-defense applications that is fired from land-, air- and sea-based platforms worldwide.
The XM1211 30x113mm High Explosive Proximity (HEP) round can sense ground and air targets using an onboard proximity sensor. These advanced munitions provide enhanced lethal effects that greatly increase effective ranges against ground targets. The XM1198 is a High Explosive Dual Purpose Self Destruct (HEDP-SD) design to engage aerial targets.
The EMAV-LW 30 is an armed version of the Expeditionary Modular Autonomous Vehicle (EMAV) completely designed by the American company Pratt Miller. The vehicle was originally created under contract to the US government to provide tactical infantry support at the platoon level. The UGV is based on a tracked chassis and is powered thanks to the use of a hybrid engine.
The EMAV is based on a tracked chassis using four wheels and one return roller. It can reach a maximum speed of 72 km/h. It can ride a gradient of 60°, a side slope of up to 60°, and is able to climb a vertical obstacle with a height of up to 60 cm.
The EMAV-LW30 is fitted with an EOS R400 Remote Weapon station armed with one Bushmaster M230LF 30mm automatic cannon. EOS is an Australian-based company that has developed a family of fully stabilized remotely operated weapon stations that can be integrated on various vehicle platforms and used for different mission profiles.
with the Mk2 variants of its RS400 RWS (Remote Weapon Station), EOS has developed a new generation of weapon station that can be configured as a single or dual weapon system to operate a variety of weapons including a machine gun, automatic grenade launcher through to the Orbital ATK M230LF 30mm cannon. In its dual configuration, it is equipped with the M230LF, 7.62mm MG (and optional missile) to provide significant and flexible lethality from a land or sea platform.
The RS400 RWS armed with the M230LF 30mm automatic cannon provides a high level of firepower. A variant of the RWS was also developed for tracked vehicles which minimizes high-frequency road and vehicle vibration to optimize the video image displayed to the operator. This variant can also track faster-moving targets such as drones.
