Sweden becomes first NATO customer to procure Rheinmetall’s Seasnake 30 naval weapon system

Delivery of the first system is scheduled for February 2028, while the four-year framework agreement also covers airburst and 30 mm calibre training ammunition. Spare parts and services are included, and the contract contains an option for up to 29 additional Seasnake weapon systems.

The Seasnake 30 is a remote-controlled naval light gun designed for close-range defence and integrates daylight cameras, infrared sensors and a laser rangefinder. It features automatic target detection, the ability to track multiple targets simultaneously and a revolver cannon with a nominal maximum rate of fire of 1,100 rounds per minute.

Equipped with integrated airburst capability, the system is described as particularly effective against aerial threats such as drones. Its low silhouette and compact stealth design are intended to reduce detectability by enemy sensors.

Rheinmetall described the Swedish order as an important market success, as it positions the Seasnake 30 with a NATO customer for the first time. The company stated that the decision reflects confidence in the performance and future viability of its naval weapon systems and reinforces its standing as a provider of maritime defence solutions within the alliance.
