The German Bundesamt für Wehrtechnik und Beschaffung (BWB) required a new recoilless autocannon, therefore the development of the RMK 30 started in 1993.

A fraction of the propellant gases is ejected to the rear of the cannon, compensating for the recoil and allowing lightweight and less rigid mounts.

[1] RMK 30 cannons have been proposed as upgrade for the Bundeswehr's (German armed forces) Tiger UHT attack helicopters.

[1] An unusual study (Project MORAINE) suggests mounting an RMK 30 gun in a retractable mast on a Type 212 submarine.

Such masts would extend the capabilities of submarines, which currently lack appropriate means to fight small surface targets or just give warning shots.
