On Monday, October 6, 2025, WB Group announced that the StormRider unmanned reconnaissance and strike surface vessel, developed by a consortium of Radmor and Arex, has completed its first stage of sea trials. As MILMAG’s editorial team learned, StormRider was remotely controlled via a satellite communication terminal for the first time.

“The StormRider unmanned surface vessel, developed by the Radmor and Arex consortium (both part of WB Group), has completed the first phase of sea trials. The maritime unmanned systems StormRider and SK@RP, the ZMU-05 remote weapon module, and the family of radios featuring national encryption will be showcased at the 23rd International Maritime and Military Fair BALTEXPO in Gdańsk. Come see us from October 7–9 at booth C.47 in Hall C of the AMBEREXPO Exhibition and Congress Center,” the company announced on the social media platform X, attaching a video clip.
The StormRider, based on the general concept of the Unmanned Surface Vessel Demonstrator (see: WB Group unveils Unmanned Surface Vessel Demonstrator), was publicly revealed in late August ahead of its planned premiere at the XXXIII International Defense Industry Exhibition MSPO 2025 in Kielce (see: WB Group unveils StormRider unmanned surface vessel).
The vessel measures just over eight meters in length and is equipped with multiple sensors and weapon systems, including a remote weapon station and loitering munitions, both developed by WB Group companies. Its design was inspired by Ukrainian unmanned surface drones used in combat against the Russian Black Sea Fleet.
The Polish unmanned surface vessel was designed for a variety of missions, including reconnaissance, engaging enemy personnel and surface targets, target identification, battle damage assessment, information operations, operational support, precision strikes, critical infrastructure protection, and maritime surveillance. It is intended to operate in coordination with manned reconnaissance vessels.
The StormRider’s reconnaissance suite includes a high-resolution, independent observation turret operating in both daylight and night-vision modes, a navigation radar, echo sounder, and sonar. Its armament consists of the Arex ZMU-05N weapon station with a 12.7 mm heavy machine gun, also produced by Arex. The module features a laser rangefinder and day/IR camera. The vessel is additionally equipped with tube launchers for Warmate TL-R and TL-C loitering munitions, as well as X-Fronter reconnaissance drones in both vertical (V) and horizontal (H) configurations.
During MSPO 2025, Bartłomiej Zając, President of Radmor, told MILMAG that the StormRider serves as a maritime component complementing WB Group’s established air and land systems, sharing proven technologies from those domains. He added that the vessel’s operational range can be significantly extended using communication relay drones such as FlyEye.
Zając emphasized that the platform is a response to the evolving nature of warfare, defined by digitalization, dronization, and robotization, which require rapid decision-making and integrated control of all such assets.
“When we talk about multidomain operations today, we are talking about building an entire ecosystem—not just an effector—which is the result of ongoing doctrinal changes on the modern battlefield,”
Zając added.
