It forms part of a larger framework agreement that also includes training ammunition in airburst and 30 mm calibre, spare parts, and services over a four-year period.
Delivery of the first system is scheduled for February 2028.
The Seasnake 30 systems will serve as the primary armament for Sweden’s new Combat Boat 90 fast military assault craft.
The contract also covers an option that allows Sweden to purchase up to 29 additional systems, depending on future requirements.
The Seasnake 30 is as a remote-controlled naval gun intended for close-range defence. It is equipped with components such as daylight cameras, infrared sensors, a laser rangefinder, automatic target detection, and the ability to track several targets simultaneously.
The weapon’s revolver cannon can fire at a nominal rate of up to 1,100 rounds per minute.
Developed from the KCA shipboard gun within the Rheinmetall group, the Seasnake 30 introduces the common 30 mm x 173 calibre. T
The system also supports individually programmable fragmentation ammunition (air burst), which is intended to enhance combat capability and tactical options against asymmetric threats.
Its integrated airburst feature enables use against aerial targets, including drones. The design aims to reduce the system’s visibility to enemy sensors through a low silhouette and compact construction.
The agreement with Sweden represents the first time Rheinmetall has sold the Seasnake 30 system to a Nato member country.
Rheinmetall stated: “This decision highlights confidence in the performance and future viability of Rheinmetall’s modern naval weapon systems. At the same time, the order reinforces the Group’s standing as a dependable provider of maritime defence solutions within the alliance.”
In July last year, the Swedish Defence Materiel Administration engaged Rheinmetall Denel Munition to supply artillery shells and propellant charges for use with the Archer artillery system.
