The Australian Army will soon take delivery of the first Mercedes-Benz G-Wagon 6×6 surveillance reconnaissance vehicles (SRV) fitted with a new customised weapons suite. Each weapon mount can accept either a Minimi 5.56mm light machine weapon or a MAG-58 7.62mm general purpose machine gun.
Under Phase 3A of Project Land 121, around 200 G-Wagon 6×6 SRVs will each receive front and rear weapon mounts developed by Australian weapon mount specialist W&E Platt. The company is currently building the mounts at a rate of about 10 sets per week. The $2.5M AUD contract also includes a spare parts package and technical documentation, and delivery of the weapon mounts will continue through the first quarter of 2014.
Designed specifically for the unarmoured 300 CDI G-Wagon 6×6 SRV platform, the weapon mount fit comprises a front rail mount for both left and right-handed gunners that is installed on the upper dash structure for the vehicle commander; and a rear skate mount fixed to the rear stowage compartment. The latter enables the gunner to engage targets left, right and to the rear of the vehicle but not to the front of the vehicle, where arcs of fire are restricted by rotation stops.
Australian Army units earmarked to receive the 6500kg gross vehicle mass G-Wagon 6×6 SRV include the three Regional Force Surveillance Units: the Pilbara Regiment, NORFORCE and the 51st Battalion, Far North Queensland Regiment. It is understood that Royal Australian Air Force Airfield Defence Guards units will also receive the vehicle.
