Medium calibre weapons

Rheinmetall's family of automatic cannons with exceptional firepower, precision and reliability

Rheinmetall’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.

20 mm x 139 Rh202

The MK20 Rh202 is a precision weapon with a high rate of fire of 1,000rds/min. Its long combat range and high accuracy allow engagement of targets, which cannot be reached with rifles, machine guns and early models of 20mm guns. The MK20 is a fully automatic, gas-operated cannon with floating mounted base, thus reducing the recoil forces and achieving maximum accuracy, reliability and service-life.

The MK20 is an open bolt weapon, i.e. in loaded condition, the bolt is in its rear position and the return springs are under tension. The cartridge is in its feeding position, the chamber is cartridge free (cook-off safety).
