The time of detonation of each airburst round is electronically programmable. In line with the Rheinmetall approach, this takes place via an infrared signal from the fire control/aiming unit once the projectile has left the barrel. The round explodes at an exactly calculated distance above its target, even if it is located behind cover. As a result, this innovative ammunition substantially enhances the combat effectiveness of the Bundeswehr's battle-proven 40mm automatic grenade launcher. With the right fire control technology, the DM131 attains a maximum effective range of 2,200 metres.
Rheinmetall is the world's leading source of 40mm technology. The Group supplies a multifaceted array of 40mm low-velocity (LV), medium-velocity (MV) and high-velocity (HV) ammunition, together with weapon systems like the Cerberus mountable grenade launcher and the Hydra automatic grenade machine gun. Thanks to built-in hydraulic shock absorbers, both weapons are suitable for MV and LV ammunition. Fire control/aiming units from the Vingmate family of products round out the Group's 40mm portfolio.
