NATO Completes Groundbreaking Exercise on Unmanned Naval Systems
NATO has concluded Exercise Dynamic Messenger 2025 in Portugal, marking a significant advancement in integrating unmanned systems into naval operations. The exercise, involving around 3,800 personnel and 260 systems from 22 nations, tested new technologies and refined operational concepts on an unprecedented scale.
The exercise combined Robotic Experimentation and Prototyping with Maritime Unmanned Systems (REPMUS) with Dynamic Messenger (DYMS), allowing NATO to trial new systems like the A9-M Autonomous Underwater Vehicle and the Pivot Remotely Operated Vehicle. These trials helped refine tactics and doctrines, strengthen unit self-defence, and respond to emerging threats.
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. Notably, Ukraine's Navy directed the opposing force, bringing frontline experience of unmanned systems and maritime combat to NATO training. Operational demonstrations covered multiple warfare domains, including naval mine warfare, persistent intelligence, surveillance and reconnaissance, and multi-domain command and control.
The exercise concluded with a demonstration of advanced data capabilities, including a 'Data Mesh' system and the Mainsail system for early warnings of potential sabotage near critical undersea infrastructure. Spanish Navy Captain Julio Hernandez highlighted the importance of collaboration between industry, academia, and NATO nations in rapidly integrating advanced technologies into operational readiness. The exercise has set the stage for further advancements in NATO's maritime capabilities.
