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. 

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). 

ELPEOS has MWIR images with high resolution, a color CCD camera, laser range finder and an integrated ballistic computer. 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. According to EurAsian Times, 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 EurAsian time stated that 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.
