some useful info -
http://www.domain-b.com/defence/general/20090526_arjun_main_battle_tank.htmlThe tank incorporates GPS-based navigation systems and sophisticated frequency hopping radios. The state-of-the-art Battlefield Management System, developed by DRDO allows it to network with other fighting units. In a search and engage operation, referred to as the "Wolfpack/Hunter Network", several Arjuns can monitor an opponent and its moves, and eliminate it in a chase or ambuscade.
It is protected by a laser warning system and smoke launchers for counter measures. To further enhance combat survivability, the tank has an auto-fire detection and suppression system. Ammunition is also stowed in watertight containers to reduce the risk of fire.
Arjun incorporates heavy composite armour and significant crew protection measures, including ammunition separated from the crew, and blow off panels on the turret bustle, and an integrated fire detection and suppression system.
The typical crew consists of a Gunner, Commander, Loader and Driver.
The Arjun also incorporates nuclear, biological and chemical protection.
Explosive Reactive Armour (ERA) panels can be added, though the current Kanchan armour is deemed sufficient for the time being. The turret and glacis are heavily armoured and use "Kanchan" (gold) composite armour. A new honeycomb design, non-explosive and non-energetic reactive armour (NERA) armour is being tested on the Arjun and is reported to be working perfectly.
The engine and transmission are provided by MTU and Renk respectively. The engine generates 1,400 hp and is integrated with an Indian turbocharger and gearbox. A local transmission is under trials and will ultimately replace the Renk supplied unit.
The tracks which were being supplied by Diehl are now being manufactured by L&T, an Indian company.
The cooling pack has been designed for desert operations.
The Arjun has a lower ground pressure than the lighter T-72, due to its design and offers a lower silhouette than comparable western tanks.
It also has a state-of-the-art hydro-pneumatic suspension, which coupled with its stabilisation and fire control system, allows superb first-hit probability. The ride comfort of the tank is highly praised though it makes the system more maintenance-intensive and expensive.

The DRDO's Combat Vehicles Research and Development Establishment (CVRDE) in Avadi, has taken up the development of a Defensive Aids System for armoured fighting vehicles (AFVs) to enhance the survivability of tanks against anti-tank guided missile (ATGM) threats and to reduce the probability of detection by target acquisition systems.
Under this project, two major systems -- an Advanced Laser Warning and Countermeasure System (ALWCS) and Mobile Camouflage System (MCS) are being developed. MCS is to provide multispectral signature management of the vehicle to reduce the vehicle signature against all known sensors and smart munitions. MCS system has been developed in collaboration with Barracuda Camouflage Ltd, Gurgaon. The system has been integrated on MBT Arjun and the performance evaluation trials have been successfully completed. The methodology and the technologies can be adopted for any AFV platform. ALWCS system comprises laser warning system, IR jammer, and aerosol smoke grenade system. This is being developed jointly with Elbit Systems Ltd, Israel. The system will be integrated on MBT Arjun and performance evaluation trials are expected during summer 2009.
