The Ukrainian company FRDM Group has unveiled an upgraded version of the ground robotic complex D-21, featuring the combat module D-18 equipped with five launchers for 70-mm rockets. A journalist from "Defense News" interviewed the developers during the Brave1 Defense Tech Valley 2025 exhibition.
The primary goal of this system is to increase the range of target engagement. The missile system can strike targets at distances of up to 10 km. With remote control capabilities, the operational range expands to 15 km.
"Our objective was to replace large multiple launch rocket systems on the battlefield. In our conditions, the firing range of such systems is about 15 km, which we cover with our product. It is significantly cheaper, more mobile, and can launch rockets from distant positions," explains a representative from FRDM Group.
The robotic platform has a payload capacity of 200 kg on soft terrains and 300 kg on hard surfaces, allowing for the installation of a module with five Hydra 70 rockets. The developer also plans to integrate more launchers for a higher-capacity chassis.
The developers note that the mobile MLRS has several applications. It can engage targets close by or fire at full range from cover, significantly reducing the system's visibility compared to larger systems.
Before heading to the combat position, operators determine the firing point and a reference for targeting. To protect the control block's cameras from dust and rocket fuel combustion byproducts, they are covered by a curtain, which opens after placing the robot in the firing position.
The MLRS is designed to use not only unguided 70-mm rockets but also laser-guided missiles. The FRDM Group team is concurrently integrating a laser targeting system on the R-34 drone, which can provide targeting assistance to the robot.
"Our infantry currently lacks sufficient tools for laser guidance. However, we have drones that can carry payloads and perform this function. Our coded solution already identifies and surveys the target, creating a laser beam with coordinates for the robot on the ground. The system then launches and guides the missile to the target via laser," explains a FRDM Group representative.
The fire system is designed with significant upgrade potential aimed at creating a complex for combating aerial targets. The future D-18 module based on the D-21 robot will seek and guide laser-guided missiles at aerial threats, such as strike and reconnaissance drones operating along the frontline.
Thus, Ukrainian developers may soon create a system similar to the American VAMPIRE air defense system with upgraded Hydra 70 missiles, which has proven effective against drones like the "Shahed".
