As global maritime threats continue to evolve, modern naval platforms increasingly rely on cutting-edge defense systems. One such system is the SeaSnake 27, a remotely operated, stabilized weapon system developed by Rheinmetall. Available since 2020, the SeaSnake 27 is designed as a primary armament for patrol boats and fast attack crafts, and as a secondary weapon system for larger vessels like frigates and corvettes.
Smart Targeting and Automatic Threat Tracking
Equipped with an integrated electro-optical sensor unit, the SeaSnake 27 features advanced multi-target tracking capabilities. Its stabilized rotating platform allows the sensor suite to independently identify, track, and engage multiple targets in real time. This makes it especially effective against fast, small targets employing swarm tactics.
Compact Design, Maximum Firepower
At the heart of the system lies the BK27 revolver cannon, firing 27mm x 145mm ammunition with exceptional accuracy. The system can utilize FAPDS (Frangible Armor Piercing Discarding Sabot) rounds — sub-caliber, high-kinetic energy ammunition developed specifically for the BK27. These rounds offer high penetration and fragmentation effects, making the SeaSnake 27 highly effective against light armored and agile threats.

Integrated or Stand-Alone Use
The SeaSnake 27 can be seamlessly integrated into a ship’s combat management system (CMS) or operate independently as a stand-alone unit. It requires no deck penetration, simplifying installation and reducing integration costs — a major advantage for navies seeking quick deployment.
A New Layer of Naval Protection
With its lightweight structure, high-precision targeting, and advanced sensor suite, the SeaSnake 27 becomes a critical line of defense against asymmetric threats, unmanned systems, and low-flying air targets. It is especially well-suited to modern naval warfare’s need for fast-reacting, multi-role protection systems.
