Aero India 2017: BEL Launches ARJUN Mk II MBT RCWS

RCWS integrated on ARJUN Mk II successfully completed tank integration

At Aero India 2017, Navratna Defence PSU Bharat Electronics Ltd. (BEL) has unveiled a new Remote Controlled Weapon Station (RCWS) for the 12.7mm gun of the ARJUN Mk II main battle tank (MBT).

The RCWS is an improvised version of BEL’s manually operated air defence gun. It enables soldiers to aim and fire at aerial targets from the safe interiors of the MBT. Currently, the 12.7mm gun of all tanks are manually operated. The RCWS integrated on the ARJUN Mk II has successfully completed tank integration and firing trials in September 2015, and also has been developed for use in Armed Repair and Recovery Vehicles (ARRV); as well is able to be mounted on hovercraft/fast moving boats for, e.g. Coast Guards.

The features of RCWS include: Remote Firing option; Automatic Cocking; DSP Based Brushless Drive Technology; 2 Axis Self-stabilised platform; Day Camera & Night Vision; Automated FCS & Ballistics corrections; and Automatic Target Tracking.

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

The system can operate on power mode without stabilisation or in stabilised mode where the gun along with the optical sensors is stabilised. The system can position the turret with an angular travel of 360° and elevate the gun in 60° to -5° elevation. The sight has a freedom of +/- 17° in azimuth and in elevation it can move from -5 to +60 degrees. It operates from the 28V DC power source available on the tank. The RCWS meets all environmental specifications and EMI specifications as per MIL STD 461 F.
