The Swedish Navy will be the first NATO member to deploy the new Seasnake 30 naval weapon system, developed by Rheinmetall.
The initial contract, signed in February 2026, provides for the acquisition of eight systems, with an approximate value of €63 million.
The systems will be installed as the main armament of the new fast assault craft Combat Boat 90. Delivery of the first system is scheduled for February 2028.
The framework agreement is valid for four years and includes airburst-capable training ammunition, 30 mm training rounds, spare parts, and support services. The contract also includes the option to procure up to 29 additional Seasnake 30 systems.
Lightweight naval system focused on short-range defense
The Seasnake 30 is a lightweight, remotely operated naval system designed for short-range defense missions. In addition to the 30 mm revolver cannon, the system integrates high-definition daylight cameras, infrared sensors, and a laser rangefinder.
It features automatic target detection and the ability to track multiple contacts simultaneously. The nominal maximum rate of fire is 1,100 rounds per minute.
One of the key differentiators of the Seasnake 30 is its integrated airburst-capable ammunition, which enhances effectiveness against aerial targets, including drones. Its compact, low-signature design helps reduce detectability by enemy sensors.
First NATO customer strengthens strategic positioning
Sweden’s order represents the first Seasnake 30 contract with a NATO member state, consolidating the system’s position in the international maritime defense market. For Rheinmetall, the agreement reinforces its role as a supplier of modern naval solutions within the alliance.
The Swedish decision also signals confidence in the system’s operational capability and technological growth potential, particularly in scenarios marked by increasing demand for protection against asymmetric threats and unmanned systems.
