Ukraine's DELTA Combat System Integrates NATO-Standard Drones and Radars at REPMUS 2026

Ukraine's Ministry of Defence reported integrating NATO-standard unmanned aircraft, surface vessels, underwater vehicles and radar feeds with its DELTA battlefield awareness system during the REPMUS 2026 exercise in Portugal. The demonstration used interfaces aligned with NATO STANAG 4817 to exchange platform data and included video integration through Ukraine's Vezha capability under challenging communications conditions. Running from August 31 to September 25, the multinational event tested interoperability across maritime and air domains using a broad collection of allied systems. The Ukrainian announcement describes a successful integration demonstration, not the permanent operational adoption of every participating platform by NATO forces.
