At the recent Northrop Grumman Bushmaster Users Conference, military and industry leaders gathered to witness the latest advancements in weapon systems and platform integration. Among the participants, EOS Defense Systems USA stood out with their unveiling of next-generation Remote Weapon Systems (RWS) technology during a live-fire demonstration.
The event provided a platform for EOS to showcase two of their latest innovations: the R800 RWS and the Slinger RWS, both of which demonstrated impressive capabilities in engaging aerial and ground targets.
The official debut of the R800 RWS was a key moment at the conference. This high-performance weapon station integrates the Northrop Grumman MK44S 30mm cannon, delivering extended range and precision in a notably compact design.

EOS has engineered the R800 to be half the size and weight of a traditional turret, yet it retains its effectiveness across a variety of operational scenarios. This reduction in size and weight enhances mobility and opens up new possibilities for integrating the system onto different military platforms. The inclusion of the MK44S 30mm cannon ensures that the R800 can engage targets with accuracy and power, even at longer distances, making it a versatile tool for modern armed forces.
In addition to the R800, EOS presented the Slinger RWS, a system tailored for counter-unmanned aerial system (C-UAS) missions. The Slinger was equipped with the next-generation Northrop Grumman M230LF dual-feed cannon and mounted on a Joint Light Tactical Vehicle (JLTV).
This setup was developed in collaboration with integration partner Pratt Miller, demonstrating the system’s adaptability and seamless compatibility with existing military vehicles. The Slinger addresses the rising challenge of unmanned aerial systems, which have become a common feature in today’s conflicts. Its mobility on the JLTV allows it to respond quickly to threats in fast-moving battlefield conditions.
In a separate configuration, the Slinger supported Northrop Grumman’s Modular Advanced Counter UAS Equipment (MACE) system, proving its flexibility and ability to work within modular defense frameworks. This compatibility with other systems strengthens its role in building layered strategies to counter diverse threats.
The live-fire demonstration at the conference put EOS’s systems to the test, engaging both aerial drones and ground targets. EOS reported that their systems “packed a punch,” successfully taking down drones and hitting ground targets with precision.
This hands-on display offered a clear look at how the R800 and Slinger perform under conditions that mirror real combat, providing military and industry observers with concrete evidence of their reliability and effectiveness. Such practical evaluations are vital for assessing whether new technologies can meet the demands of actual operations.
Hosted by Northrop Grumman, the Bushmaster Users Conference serves as an essential venue for bringing together military personnel and defense industry experts to explore emerging capabilities in weapon systems and their integration onto various platforms.
The event creates a realistic field environment where new technologies can be assessed, offering companies like EOS a chance to demonstrate their solutions to an audience directly involved in defense planning and procurement. Beyond showcasing individual systems, the conference encourages collaboration and the sharing of insights, driving progress in the defense sector as a whole.
Remote Weapon Systems like those developed by EOS have become critical in modern warfare, blending firepower and precision with enhanced safety for operators. By enabling soldiers to engage targets from protected positions, these systems reduce exposure to danger while maintaining combat effectiveness.
The R800’s compact yet powerful design and the Slinger’s specialized focus on countering unmanned aerial threats reflect the evolving needs of military forces, where adaptability and accuracy are increasingly important. These advancements position EOS as a key contributor to the future of defense technology.
EOS Defense Systems USA’s showcase at the Northrop Grumman Bushmaster Users Conference marks a notable step forward in remote weapon systems technology. The introduction of the R800 RWS and the demonstration of the Slinger RWS reveal EOS’s commitment to advancing what’s possible in this field.
These systems offer improved performance and greater flexibility, essential qualities for addressing the varied and dynamic challenges of modern conflicts. As threats continue to evolve, innovations like those presented by EOS will be crucial in equipping military forces to meet future demands effectively.
