Introducing the Enhanced D-21 Ground Robotics System
Ukrainian company FRDM Group has unveiled the upgraded version of the ground robotics system D-21, now featuring the D-18 combat module equipped with five launchers for 70-mm missiles. A journalist from "Oboronka" interviewed the system developer during the Brave1 Defense Tech Valley 2025 exhibition.
The primary goal of the company was to enhance the target engagement range of the D-21 system. The missile system can strike targets at distances of up to 10 km. With the ability to control the robot from 5 km away, the effective range extends to 15 km.
"Our aim with this system was to replace large multiple launch rocket systems on the battlefield. In our context, such systems have a firing range of about 15 km, which we cover with our product. It is significantly cheaper, more mobile, and can launch missiles from a distance," explained a representative of FRDM Group.
The robotic platform has a payload capacity of 200 kg on soft ground and 300 kg on hard surfaces, allowing for the installation of a module with five Hydra 70 rockets. However, the developers are planning to integrate more launchers for heavier chassis.
The development team notes that the mobile MLRS has several application scenarios. It can engage targets nearby or fire at full range from behind trees and bushes, significantly reducing the system’s visibility compared to larger systems.
Before heading to the combat position, operators identify a firing point and a reference for targeting the system. To protect the control module's cameras from dust and rocket fuel combustion products, they are covered with a shield that opens after positioning the robot at the firing location.
The MLRS is designed to utilize not only unguided 70-mm missiles but also laser-guided ones. The FRDM Group team has simultaneously integrated a laser targeting system onto the R-34 drone, which can provide targeting information for the robot’s missile launches.
"Our infantry currently lacks sufficient tools for laser targeting. However, we have drones capable of carrying payloads and performing this function. Our coded solution can already detect, scout a target, and create a laser beam with coordinates that the robot on the ground is aimed at. Then the system executes the launch, and the missile is guided to the target via laser," explained a representative of FRDM Group.
The fire system has significant modernization potential aimed at developing a complex for engaging aerial targets. The prospective D-18 module based on robot D-21 will aim to laser-guide missiles at aerial targets—both strike and reconnaissance drones operating along the front line.
Thus, Ukrainian developers may soon create a system similar to the American VAMPIRE air defense complex with upgraded Hydra 70 missiles. This system has proven effective against drones such as the "Shahid."
