EOS Defense Systems USA has demonstrated its R400 Remote Weapon System integrated onto an unmanned surface vessel developed by BlackSea Technologies. The vessel, known as Chaser, was unveiled at Sea-Air-Space 2026 in the United States.

The company participated as a mission partner on the platform, supplying the gun system as part of a broader configuration involving multiple industry contributors. These included Lockheed Martin providing a JAGM launcher, Echodyne supplying radar systems and Current delivering perception camera systems.

The integration demonstrates the adaptability of the R400 system to new operational platforms within a short timeframe. The system transitioned from concept to a live maritime demonstration within weeks.

 

 

The demonstration combines remote operation via satellite communications, maritime integration and autonomous deployment into a single operational capability. These elements had previously been demonstrated separately but were unified on one platform.

The deployment highlights the flexibility of the R400 system across multiple domains. It extends the system’s application into maritime and autonomous operations.

This marks the first deployment of the R400 on an unmanned surface vessel in the United States. The development is expected to open new opportunities for engagement with U.S. Navy stakeholders.

The demonstration is anticipated to support further testing and operational assessments. It reflects growing demand for integrated autonomous and remotely operated defense capabilities.
