DRDO rather than starting all over again the Arjun Mk.2 will have the same design of Arjun Mk.1, but major changes are planned for the new generation variant of Arjun Tank to keep up with the new technological changes which are been incorporated in the MBT’s world over.

Arjun Mk.2 will have Battle Field Management System (BFMS) which will enable the tank to get feed from UAV‘s and Helicopters, which then enable the Arjun Mk.2 tank crew much aware of their surroundings and better understanding of the battle zone, this will lead to improvement in coordinating with other Friendly tanks in the zone and also avoid Friendly kills, it will also give information regarding enemy tank movement along with their troops and help navigate terrain in the battle zone.

Self-diagnostic system (SDS) will also be added to Arjun Mk.2 which is like a health monitoring system. it will not only tell the tank crew if it is having any problem but also point out the trouble area , it is also important when Tank has taken multiple hits from different position and from different ammunition after a self-diagnose Tank crew will know exact damage inflicted on the Tank .

Arjun Mk.2 will get a new efficient 1500bhp engine which has been in development by DRDO in India its self, they are reports that a Indian Private industry is also working with DRDO on the engine development, currently Arjun Mk.1 is powered by German supplied 1400bhp engine which is quite old in design and technical parameters but still a powerful and respected engine in the world.

NERA (non-explosive reactive armor) will be added to Arjun Mk.2 this will give the tank additional protection against anti-tank munitions, unlike ERA, NERA will enable tank to take multiple hits anti-tank munitions, but also increase the weight of Arjun Mk.2 to 60 tons from its current weight (Arjun Mk.1) of 58 tons.

It is much likely that Arjun Mk.2 will also spot Air-conditioning system for the crew, which will be powered from an APU which will draw its power from the Main engine of the Tank; this will enable the tank crew to operate in higher temperature of desert heat without any discomfort to the tank crew, Arjun Mk.1 already has hardened electronics that function perfectly even in the Rajasthan summer without requiring any Air-conditioning system

The Arjun Mk.2 is to undergo summer and winter trails in 2012. If the tests are satisfactory, then the tank will be able to begin production in 2014.

FMBT

The Indian Army wants the tank to have an Identification Friend or Foe (IFF) system “to obviate chances of own tanks firing at each other in battle”, and a whole new reliable and secure mobile communication system capable of data transmission, audio and video conference. Protection in the form of soft-kill system requires IR detectors, laser warning, radar warning and devices to instantaneously integrate these signals and control a countermeasure suite. Such systems are threat specific so all would have to be carried on a vehicle to gain protection against more than one part of the EM threat spectrum.

For mobility, in order to achieve ‘extraordinary’ acceleration, the Army observes that it is necessary to seek a compact power pack in the form of a gas turbine. The Army wants an active suspension system with sensors, control units, and a hydraulic power source in combination, to automatically alter the suspension characteristics to more closely match the speed of the vehicle and the terrain profile, especially in Indian terrain conditions.

The Army says it wants a high-performance armour system on its FMBT with advanced materials incorporating the following qualities A. Reduced penetration by most lethal weapons, B. Elimination of parasitic mass leading to a weight reduction, C. Excellent corrosion resistance, D. Inherent thermal and acoustic insulation properties.
