At the MSPO defense exhibition currently taking place in Poland, Radmor and Arex — both part of the private defense consortium WB Group — presented their joint naval drone projects: StormRider and SK@RP.
WB Group openly acknowledges that these systems were developed in response to market demand and the lessons of the war in Ukraine.

StormRider is a large, multipurpose naval drone comparable to Ukraine's Sea Baby. Measuring 8.5 meters in length and weighing 3.5 tons, it is designed for both reconnaissance and strike missions.

StormRider can be fitted with a remote weapon station, such as the ZMU-05N heavy machine gun module showcased at MSPO, or with Warmate TL loitering munitions launched from transport-and-launch containers.
The platform has already undergone trials in the Baltic Sea, which is considered the most likely theater for its employment in the event of conflict with russia.
By contrast, SK@RP is a much smaller platform developed as a one-way attack drone. It carries only a surveillance camera and essentially replicates the functionality of Ukraine's Magura V5, though with smaller dimensions and a lighter warhead.
WB Group emphasizes that all subsystems of the drones — including remote-control and autonomy solutions — are of Polish origin. This marks a key distinction from Ukrainian designs, which rely heavily on satellite communications.
For Poland, however, and under the operational conditions of the Baltic Sea, satellite connectivity is not essential. The distance from the Polish coast to the russian Baltic Fleet's main base in Baltiysk, Kaliningrad Oblast, is just 25 kilometers.
