KMW of German unveiled a derivative of its FLW200 RCWS known as FLW200+. The new system can host not only light weapons, but also a 20 mm cannon, namely the Rheinmetall Rh202 DM6A1. The FW200+ weighs approximately 400 kg including the gun and one hundred 20×139 mm rounds, the Rh202 having a dual feed capability.

Stabilised on two axis, it has an elevation arc of –10°/+50° and defined fire/no fire zones can be established by the crew.

The optronic suite is hosted in a box on the right side of the mount and includes a CCD colour zoom camera, a laser rangefinder and a thermal imager; considering the longer ranges involved the TI system adopted is of the cooled type.

Leveraging the family concept KMW maintained numerous components in common with the FLW100/200 RCWS, such as the control system and the display, as well as mechanical interfaces. The FLW200+ is designed to accept a further weapon system on the top; this can come in the form of either a missile launcher or a light machine gun, though self-defence grenade launchers can also be fitted.

At EUROSATORY 2012 a Boxer APC was shown with a modified FLW200+ with the Rh 202 standard 20mm machine-canon of the Marder AIFV.
