# Ukraine Demonstrates Maritime Drone Integration in Portugal

Ukraine reported that its DELTA command-and-control system integrated aerial, surface, and underwater uncrewed systems with radar data during the REPMUS 2026 multinational exercise in Portugal. Some assets transmitted telemetry using NATO STANAG 4817. This was an interoperability demonstration—not a procurement announcement—and no contract, funding, delivery schedule, or NATO-wide adoption decision was reported.

- For defense contractors, the exercise provides a practical signal of interoperability areas relevant to future maritime uncrewed-system work: integrating different platforms and radar data, telemetry standards, resilient communications, and command-and-control security.
- The Ministry of Defence of Ukraine, Portuguese Navy, NATO Allied Command Transformation, and NATO are relevant stakeholders identified in the exercise context; the signal does not establish a procurement commitment by any of them.
- Companies may use the demonstration to assess their system interoperability capabilities and, as the signal suggests, follow subsequent interoperability trials and requirements. No active solicitation or submission deadline is identified.
