The R400S remote weapon station (RWS) is capable of employing up to 30 x 113mm firepower at a significantly lower weight and with greater accuracy and reliability than other RWS within the marketplace. 

The R400S can accommodate a variety of other weapons including machine guns, automatic grenade launchers and missile systems, providing a tailorable lethality overmatch in every combat situation. The modularity of the system provides the capability to change weapon configurations in less than one hour.

The weapon system is controlled by the same components and user interface as the EOS family of RWS, minimizing the training burden for the organization and individuals.
