EOS has demonstrated its R400 Remote Weapon System integrated onto an unmanned surface vessel developed by BlackSea Technologies. The Unmanned Surface Vehicle (USV), Chaser, was unveiled at Sea-Air-Space 2026 in the United States. EOS Defense Systems USA is a mission partner on the USV, providing the gun system as part of the vessel’s configuration, alongside partners including Lockheed Martin (JAGM launcher), Echodyne (radars) and Current (perception camera systems). This integration demonstrates how rapidly EOS’ R400 can be adapted to new platforms, moving from concept to live maritime demonstration in a matter of weeks.
It brings together remote operation over satellite communications, maritime integration and autonomous deployment into a single, working capability, combining elements previously demonstrated separately onto one platform. It also highlights the versatility of the R400 across multiple domains, extending its application into maritime and autonomous operations. As the first time R400 has been deployed on an unmanned surface vessel in the US, it creates a new pathway for engagement with US Navy stakeholders, reflecting growing demand for these capabilities. The demonstration is expected to support further testing and operational assessment activities.
The R400 Marine (R400-M) brings the advanced functionality of our land-based R400 remote weapon system to the maritime domain, using maritime-compliant subcomponents and finishes that meet applicable standards and test requirements. The system can fire a wide range of weapon systems, from 7.62 mm machine guns up to 30 × 113 mm cannons firing proximity-fuzed munitions to ranges of about 2,000 m. It also supports Javelin, Stinger, and Spike missiles, extending engagement capability to 4,000 m. This weapon compatibility delivers adaptability across maritime operations, from close-in ship self-defense to extended-area engagement.
EOS has designed, manufactured and exported advanced technology systems for nearly 40 years. The company product range covers remote weapon systems, turrets, high energy laser weapons, counter-drone systems, and space intelligence and space control services. EOS’ Firepower Systems offer a cost-effective solution for medium-calibre firepower, suitable for integrating with new vehicles or upgrading existing reconnaissance and assault vehicles. The company systems minimise costs and programme complexity while incorporating advanced features such as 30 mm cannons, anti-tank guided missiles, surface-to-air missiles, novel effectors, and advanced electro-optic systems.
