Bengaluru, February 14, 2017: Navratna Defence PSU Bharat Electronics Ltd (BEL) has unveiled a new Weapon Control system — Remote Controlled Weapon Station (RCWS)/Air Defence Weapon Station (ADWS) for 12.7 mm Gun of MBT Arjun Mk II battle tank, at Aero India 2017, today.

The RCWS is an improvised version of the manually operated air defence gun. It enables the soldier to aim and fire at aerial targets from the safe interiors of the battle tank. Presently, the 12.7 mm guns of all tanks are manually operated. RCWS integrated on MBT Mk II has successfully completed tank integration and firing trials in September 2015. RCWS has also been developed for use in Armed Repair and Recovery Vehicle (ARRV). It can also be mounted on hovercraft / fast moving boats for the Coast Guard. 

Thefeatures of RCWS include: Remote Firing option; Automatic Cocking; DSPBased Brushless Drive Technology; 2 Axis Self-stabilised platform; Day Camera& Night Vision; Automated FCS & Ballistics corrections; and AutomaticTarget Tracking.


The RCWS forMBT ARJUN Mk II is intended to lay and stabilise the NSVT 12.7 mm machine gunalong with the optical sensors in traverse and elevation mounted on the MBTturret. The system allows the operator to control the gun and sight from theoperating console and joy stick from inside the turret. The opticalsensors include a day camera, Thermal Imager and a Laser Range Finderintegrated on a single housing. The system allows automatic target tracking forair and ground targets and performs necessary ballistic computations to feedthe ballistic offsets to the gun / sight. The system has a provision for theoperator to do automatic loading and firing of the gun. 


Thesystem can operate on power mode without stabilisation or in stabilised modewhere the gun along with the optical sensors is stabilised. The system canposition the turret with an angular travel of 360 deg and elevate the gun in 60to -5 degree elevation. The sight has a freedom of +/- 17 degree in azimuth andin elevation it can move from -5 to +60 degree. It operates from the 28VDC power source available on the tank. The RCWS meets allenvironmental specifications and EMI specifications as per MIL STD 461 F.
