Arjun Mk1A Main Battle Tank to be upgraded with electro-optical fire control

 October 12 2022:  India is set to outfit its domestic Arjun Mk1A main battle tank (MBT) with an electro-optical (EO) fire-control system, allowing the tank to target with greater precision. reports the government-run newsletter INDIAai citing a report in the international defence publication, Janes.
The Mk1A is an upgraded version of the Arjun platform with increased firepower, maneuverability, and survivability, designed and developed by the DRDO. According to the Janes report, Bangalore-based Tonbo Imaging is building the system in collaboration with the state-run Bharat Electronics Limited (BEL) plant in Chennai, India. 
The Elpeos fire-control product will be delivered as part of the deal and integrated into the Arjun MK1A MBIs. According to the Tonbo imaging website, ELPEOS is a multi-sensor electro-optical payload developed for precision targeting and easy integration into remote-controlled weapon systems. (RCWSc). 
The Elpeos system has been designed for integrated automatic target tracking and electronic video stability. It has a gyroscope-based stabilising mechanism that compensates for vibrations, providing steady images.The system automatically identifies and tracks multiple targets, with the objective to reduce the soldier's involvement. The system analyses the images to identify the target of interest within a specific area, decreasing user participation.
It integrates a cooled medium-wave infrared (MWIR) imager, a colour high-definition (HD) charge-coupled device (CCD) camera, a laser rangefinder (LRF), and a ballistic computer. The integrated LRF has a range of 6 km and delivers target data directly to the fire-control system.For target acquisition and georeferencing, it can optionally incorporate a GPS and a digital magnetic compass with an inclinometer.  
With this system, it is easier for tanks to acquire, loc, and engage moving targets using human or automatic tracking. The system has three features: automatic target detection, tracking and classification. Low power consumption and weight are free from foreign export and incising requirements and India’s only indigenous RCWS sighting system.  
Arjun MK1A tank has significant enhancements over the Arjun MBT, the Indian Army’s existing main compact tank in service. Furthermore, the MK1A can operate in all terrains and engage targets at night. 
The driver has a seat that provides additional protection during a mine blast. In addition, an integrated explosive reactive armour system is installed in the turret and the front portion of the chassis.  The Arjun MK II or MK1A is powered by a German V-90 turbocharged, charge-cooled, water-cooled diesel engine producing 1030 kW at 2,400 rpm. The Arjun Mk II has an epicyclic gearbox, a hydrodynamic torque converter, a mechanical lock-up clutch, a hydrodynamic retarder, and four forward and two reverse gears.
