One of the novelties presented at the ZM Tarnów booth during the MSPO Exhibition is a variant of the remotely controlled armament module - ZSMU - offering an option of quick replacement of the .50 cal. machine gun with the 40 mm automatic grenade launcher - HK GMG. Alternatively, a 7.62 mm machine gun may also be mounted within the module.
The ZSMU-1276 module is being used, among other vehicles, in case of the Rosomak WRT IFV. In that case the module is fitted with a 7.62 mm UKM-2000C machine gun. The standard variant is equipped with .50 cal. WKM-B machine gun (optionally - .50 cal. NSW machine gun), with ammunition supply provided by a box containing 150 rounds of ammunition.
The module, presented during the MSPO event, could also be fitted, thanks to a special-purpose mounting adapter, with the 40 mm automatic GMG grenade launcher manufactured by the Heckler & Koch company, or with a 7.62 mm UKM-2000C machine gun.
ZSMU module may additionally be integrated with the PCO S.A.-produced ZMO-1 or ZMO-2 “Horus” optronic systems, both of which are fitted with a thermal vision camera and a laser rangefinder.
ZSMU is controlled by a single operator. The kit that is tailored to be fitted with the .50 cal. machine gun has a weight of - along with the ammunition - 190 kilograms. In case of the 7.62 mm machine gun it is 28 kilograms lighter. The system is capable of covering 360 degree sphere with fire, with the elevation ranging from -5 to +50 degrees.
The optronic system itself - coming in the ZMO-2 variant - makes it possible to carry out observations:
1.54 µm wavelength laser range-finder makes it possible to measure the distances between 100 and 10 000 meters.
