Rheinmetall's family of medium calibre cannons

Rheinmetall Defence’s portfolio of medium-calibre automatic cannons is based on the products of two highly regarded companies: Oerlikon and Mauser. Rheinmetall continues to build on their legacy, developing and manufacturing automatic cannons featuring exceptional firepower, precision and reliability. Rheinmetall is proud to present its current family of medium-calibre cannons in the 20 mm to 35 mm calibre range.

Designed to retain their firepower, precision and reliability even under extreme environmental conditions, they have excellent mass-to-performance ratios, compact designs, long service lives and reduced recoil forces – to name just a few of the factors that make our cannons the ideal solution for ground, naval and air applications. They are designed with the user in mind. For example, service members can fieldstrip them without special tools, while the Group’s replacement part packages reflect our extensive in-service experience.

SeaSnake – Light Naval Gun System

The SeaSnake is a remote-controlled, semi-automatic, stabilized CIWS defense system with an optional integrated or detachable E/O sensor unit on a stabilized pan and tilt platform that can be moved and steered independently of the weapon. The multi-target tracker integrated in the system represents state-of-the-art technology at the highest level and enables, among other things, simultaneous multiple target tracking and automatic target recognition. The bus system used in the SeaSnake, which is qualified in accordance with IECEN61508&MIL-STD-882, facilitates integration into a Combat Management System. In addition, the SeaSnake can also be used independently as a “standalone” system.
