LW25 Bushmaster
Lightweight 25mm Bushmaster Chain Gun TM
Warfighters can meet the need for a more flexible, reliable, and lethal lightweight weapon system by selecting ATK’s LW25Bushmaster Chain Gun TM. It builds upon the combat proven Bushmaster tradition of excellence and includes such features as:• Dual Feed System — This gives the Warfighter the flexibility to select between two different types of ammunition during
the fight, depending on the threat situation and desired lethality. This affords options when faced with difficult rules ofengagement that require quick transition between a lethal and non-lethal response. Next round select capability enablesusers to switch between the two feeds, with the next round fired being the newly selected ammunition.
• Increased Lethality — The system includes a robust family of ammunition and is compatible with ATK’s ProgrammableAirburst Munition (PABM) technology. The PABM round affords the ability to defeat troops in defilade and greatly enhanceslethality over current legacy weapon systems. Additionally, the gun is capable of firing the current XM307 and LW25 ammu-nition. This provides Warfighters scaleable lethality, from non-lethal to airburst, based on the specific conditions of the mis-sion at hand.
• High Reliability — Due to its externally powered (electric) chain driven design, the system has a Mean Rounds BetweenStoppages (MRBS) in excess of 35,000 rounds. This allows Warfighters prolonged use in diverse applications and difficultenvironments where performance and sustained firepower are crucial. Sluggish performance and constant stoppages are athing of the past.
• Remote or Manned Operation — Due to its externally powered chain driven action, the gun can be fired remotely fromweapon stations while the crew remains protected and under armor without the need for charging and manually clearingstoppages. This is particularly important for applications such as MRAP where gun access and system reliability demandsuch flexibility. The gun system has been integrated and fired from the Common Remotely Operated Weapon Station(CROWS). The system also can be employed in manned applications on ground, naval, and helicopter aviation platforms.
• Compact Lightweight System — The gun is a compact lightweight design based on the highly successful Bushmasterfamily of Chain Guns TM. This combat design allows the Warfighter ease of use and leverages over the twenty five years ofengineering expertise. This compact design makes it ideal for lightweight applications currently limited to gas operatedguns. The system is lighter, more compact, and offers a dramatic increase in lethality over the current M2 .50cal., M2407.62mm, and Mk19 40mm Grenade Machine Gun.
