German Navy Frigate Sachsen Conduct First Tests of High-energy Laser Weapon Against Drones

It was a big step in the direction of fully operational laser weapons. For the time ever, the German Armed Forces fired a shipboard laser weapon. On August 30th 2022, the German frigate Sachsen successfully engaged drones at short and very short range in the Baltic Sea near Putlos Major Training Area. The laser weapon demonstrator was developed by the High-Energy Laser Naval Demonstrator working committee (“ARGE”), consisting of MBDA Deutschland GmbH and Rheinmetall Waffe Munition GmbH. Future high-energy laser (HEL) weapon systems for the Navy will be especially useful in defending against drones and drone swarms as well as engaging attacking speed boats at close and very close range. But the system can also be designed for greater output, enabling it to destroy guided missiles and mortar rounds.

The joint integration and test phase of the naval demonstrator started in November 2021, which the ARGE integration team concluded with a successful factory acceptance test at Rheinmetall’s Unterlüß proving ground. The demonstrator was then installed onboard the frigate Sachsen in Kiel. In July 2022 the first test campaign took place in Eckernförde Bay near the Bundeswehr’s Technical Centre for Ships and Naval Weapons, Marine Technology and Research, WTD 71, in Surendorf. During the trials, the capabilities of various sensors, including the electro-optical sensor suite from the ARGE and the radar, were verified. In addition, the interplay between all the components and procedures in the entire operational sequence from target acquisition to engagement was put to the test. The trials included multiple highly realistic engagement scenarios. The test planning and the provision of various types of targets on land, at sea or from the air were carried out and organised by the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). The test management was carried out by WTD 71.

Daniel Gruber, naval demonstrator project manager at MBDA Deutschland, and Dr. Markus Jung, in charge of laser weapon development at Rheinmetall Waffe Munition GmbH, were on hand to observe the test campaign with the frigate. Looking back on the integration and test phase, they drew a positive conclusion.“Solid teamwork between the two ARGE partners played a key role in helping us integrate a fully functional, high-performance demonstrator onboard the frigate. Close cooperation with the command team of the Sachsen enabled direct communication with the future user.”

Dr Thomas Baumgärtel, project manager for the naval demonstrator at Rheinmetall Waffe und Munition GmbH, was also satisfied with the outcome: “The principal components of the demonstrator are truly high tech. This is the result of long years of research at both the participating companies. Many of the demonstrator’s system components were developed specially for the project and combined in this form for the first time.”

Both Doris Laarmann, head of laser activities at MBDA Deutschland, and Alexander Graf, in charge of programme management for laser weapons at Rheinmetall Waffe und Munition GmbH, emphasized how the current trials have now set the basic stage for introducing laser weapon systems and capabilities into the Bundeswehr – capabilities whose relevance is by no means restricted to the Navy. Testing of the high-energy laser weapon will continue until mid-2023. In subsequent test campaigns, new scenarios will challenge the demonstrator’s capabilities. Effector-related tasks in the ARGE are basically evenly divided. MBDA Deutschland is taking care of target detection and target tracking, the operator console and linking the laser weapon demonstrator to the command-and-control system. Rheinmetall is responsible for the slewing system, the beam guidance, the demonstrator container as well as mechanical and electrical integration of the demonstrator onto the deck of the Sachsen, and finally for the high-energy laser source, including its periphery.
