New DOT-Chain System Grades Drones by Combat Performance—Built for Ukrainian Forces

DOT-Chain Defence, the weapons marketplace, has launched a new rating system that allows Ukrainian soldiers to evaluate drones and leave feedback based on their performance in combat conditions.

According to the Ukrainian Ministry of Defense on October 9, this feature will help frontline units make more informed procurement decisions by considering not only technical specifications but also real battlefield experience.

Each authorized user can now rate a drone on a five-point scale—from 1 (“unsatisfactory”) to 5 (“excellent”)—and provide comments detailing advantages, drawbacks, ease of use, build quality, and resistance to interference.

For now, only military users can view the ratings, but the feature will later be expanded to include manufacturers. This will enable direct communication between producers and operators, allowing companies to respond to feedback from the field.

The Ministry added that the rating system was introduced at the request of servicemembers who participated in the DOT-Chain pilot project. It marks the first step in a broader plan to implement improvements suggested during field visits and soldier surveys.

In parallel, Ukraine is expanding its Drone Army Bonus program. Defense Minister Denys Shmyhal announced that service members can now order electronic warfare (EW) systems through the DOT-Chain Defense platform—in addition to FPV drones and bombers previously available under the initiative.

According to Shmyhal, the expansion will strengthen troop protection on the front line. The Defense Procurement Agency has already signed contracts with domestic manufacturers, and part of the EW equipment has been delivered to the Armed Forces.

Earlier, it was reported that in its first month of operation, the DOT-Chain Defense system delivered 5,600 drones worth a total of $5.4 million to the front line.
