AGRAB mortar nears production
Christopher F Foss
Under the project leadership of the International Golden Group, an international consortium has developed the 120mm AGRAB (Scorpion) self-propelled (SP) mortar system.
Development of this commenced in early 2006 in response to anticipated future operational requirements for a highly mobile SP system with a high level of protection. The system integrates the Singapore Technologies Kinetics (STK) 120 Super Rapid Advanced Mortar System (SRAMS) onto the rear of the latest combat-proven BAE Systems OMC RG-31Mk 5 (4x4) mine-protected armoured utility vehicle. A total of 46 rounds of 120mm mortar bombs plus associated charges are carried in two carousels, each holding 23 rounds. In addition there are two further ready racks, which hold a total of 12 ready rounds.
All the 120mm mortar bombs have been supplied by Denel, with the exception of the Improved Conventional Munition (ICM), which has been developed by STK.
Maximum range depends on the charge fitted, but using a high explosive mortar bomb and top charge, a maximum range of 8,200m can be achieved. Also fitted as standard is the FIN3110 ring type laser gyro navigation system, which can be combined with other sources of navigation – including GPS – to provide accurate pointing.
To enable targets to be rapidly engaged, the Denel Arachnida computerised fire control system is installed, which not only increases accuracy but also allows the weapon to come to a halt, open fire and redeploy to another fire position before counter battery arrives.
The system has a crew of three – commander, loader and driver – and can come out of action in about 30 seconds. Unlike some other systems of this type, no stabiliser has to be lowered to the ground before firing commences.
Since firing trials started in mid- 2006, more than 800 120mm mortar bombs have been fired in four series of user trials. It is expected that the complete system will be type qualified next month.
Rapid development of the AGRAB system has been achieved because all the key subsystems have already been proven in other applications, especially in the Middle East.
