Details: The combat system was tested at the annual REPMUS 2026 (Robotic Experimentation and Prototyping with Maritime Unmanned Systems) international exercise, led by the Portuguese Navy.

Unmanned aerial, surface and subsurface systems, as well as radars, were integrated into the Ukrainian combat system.

Quote: "During the exercise, partners and Allies practised the joint employment of unmanned aerial, surface, and subsurface systems and tested interoperability within multinational forces. It is the largest international exercise focused on employing unmanned systems in maritime operations."

Details: According to the Defence Ministry, the Ukrainian team, participating in the exercise for the third time, coordinated its activities through DELTA. In particular, the military and their allies practiced maritime operations, namely reconnaissance, maritime area monitoring, manoeuvring, and escort and simulated engagement exercises.

The Defence Ministry noted that assets transmitting telemetry in line with NATO STANAG 4817 had already been integrated into the Ukrainian combat system.

Quote: "During the exercise, Ukrainian service members also shared combat experience with partners, particularly in the employment of unmanned systems in the maritime domain."

Details: The DELTA system is a Ukrainian situational awareness platform that ensures the collection, processing and display of information regarding enemy and friendly forces in real time, creating a single digital picture of the battlefield. It is an ecosystem of digital military products, which notably includes the Army of Drones.Bonus ( e-points ) programme, where strikes on enemy targets carried out by units using UAVs are recorded and confirmed.

In early 2026, the Mission Control module was introduced into DELTA, recording data on mission execution, the employment of unmanned systems and the results of combat operations.

Background: Earlier, Ukrainska Pravda reported that all DELTA users had been granted access to an AI assistant to work within the interface.
