According to The New York Times, NATO countries played an active role in funding the development of Ukraine’s Delta system, which was designed to improve coordination between different units of the Ukrainian Armed Forces.

The platform is built around a digital battlefield map that allows troops to identify targets and exchange operational data more quickly.

The newspaper reported that NATO supported the project in an effort to bring Ukraine closer to the alliance’s own doctrine of rapid battlefield coordination. However, Ukrainian forces were initially reluctant to adopt the system on a broad scale and continued to rely heavily on paper maps and radio communications.

That changed after the conflict began. According to the report, Delta quickly proved its practical value, prompting its wider deployment across Ukrainian units. By the summer of 2025, it had become a unified battlefield management platform used throughout the Ukrainian military.

Delta had already entered service with the Ukrainian Armed Forces in 2018. It was developed as a situational awareness and decision-support tool intended to improve coordination between different units.
