EOS R400 demonstrated on USV, extending into maritime operations

EOS has demonstrated its R400 Remote Weapon System integrated onto an unmanned surface vessel developed by BlackSea Technologies. The vessel, 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.
