NATO's Unmanned Systems Integration Showcased in Portugal
NATO has wrapped up Exercise Dynamic Message 2025 in Portugal, marking a significant milestone in the integration of unmanned systems into naval operations. The exercise, held on an unprecedented scale, brought together over 3,800 personnel and 260 systems from 22 nations, with observers from 13 more countries. It was notable for Ukraine's Navy directing the opposing force for the first time, sharing frontline experience of unmanned systems and maritime combat with NATO training.
The exercise combined Robotic Experimentation and Prototyping with Maritime Unmanned Systems (REPMUS) with Dynamic Message (DYMS), providing a live environment to test new technologies and refine operational concepts. Standing NATO Maritime Group 1 (SNMG1) and Standing NATO Mine Countermeasures Group 2 (SNMCMG2) played central roles in rehearsing defences against unmanned aerial and surface threats. The event helped refine tactics and doctrines while strengthening unit self-defence and the ability to respond to emerging threats.
Operational demonstrations covered multiple warfare domains, including naval mine warfare, persistent intelligence, surveillance and reconnaissance, protection of undersea infrastructure, countering unmanned vehicles, and multi-domain command and control. NATO's Centre for Maritime Research and Experimentation introduced advanced data capabilities, including a 'Data Mesh' system for governance and sharing, and trialled the Mainsail system for early warnings of potential sabotage near critical undersea infrastructure. Several participating firms were supported by NATO's Defence Innovation Accelerator for the North Atlantic (DIANA), linking innovation initiatives with operational requirements.
Exercise Dynamic Message 2025 has concluded, leaving a lasting impact on NATO's operational readiness. The exercise has not only tested and refined the use of unmanned systems but also fostered collaboration between industry, academia, and NATO nations. With Ukraine's involvement, the exercise brought a unique perspective to NATO training, further enriching its scope and value.
