IDEX 2015

Mobile mortars complete [IDX15D3]

25 February 2015

Having been awarded a contract worth AED786 million for 72 production systems, the International Golden Group (IGG) of Abu Dhabi has now integrated the last batch of Agrab Mk 2 120mm Mobile Mortar Systems (MMS) for the UAE Armed Forces. The first batch of 10 was integrated in South Africa, with the remaining 62 being produced at the facilities of IGG (Stands 04-C20, UM-48) in the UAE.

Agrab Mk 2 comprises a BAE Systems Land Systems South Africa RG31 Mk 6E mine-protected vehicle with a Singapore Technologies Kinetics 120mm Super Rapid Advanced Mortar System (SRAMS) integrated into the rear, controlled by a Thales South Africa Systems integrated fire control system. The vehicle is powered by a Cummins turbocharged diesel developing 360hp at 2,600rpm, coupled to an Allison six-speed automatic transmission, to give a maximum road speed of 90km/h.

The vehicle has a Platt Protected Weapon Station armed with a .50 M2 HB machine gun, plus banks of electrically operated grenade launchers.

The 120mm SRAMS fires over the rear arc with elevation limits from +45° to +80°, and a traverse of 40° left and right. The 120mm ammunition is supplied by Rheinmetall Denel Munitions; currently available are high-explosive (HE), bi-spectral smoke and illuminating rounds, all of which are not armed until 40m from the barrel. Maximum range is typically 8.1km for an HE mortar bomb.

ST Kinetics’ smooth-bore 120mm mortar system is currently being qualified to fire a rocket-assisted projectile out to a maximum range of 13km, as well as a laser-guided mortar bomb for the precise engagement of targets designated by a forward observer or unmanned aerial vehicle. The fire control system incorporates an automatic laying capability, ballistic computation that includes a feed from the onboard meteorological sensor, and overall weapon management. The Selex FIN3110 ring laser gyro inertial navigation system is integrated under the 120mm SRAMS.

As well as being used in autonomous mode, one Agrab Mk 2 120mm MMS can control the fire mission for up to 12 other platforms for maximum target effect.
