Arjun Main Battle Tank

  • The Arjun Main Battle Tank project was initiated by DRDO in 1972 with the Combat Vehicles Research and Development Establishment (CVRDE) as its lead laboratory.
  • The objective was to create a “state-of-the-art tank with superior firepower, high mobility, and excellent protection”.
  • During the development, the CVRDE achieved breakthroughs in the engine, transmission, hydro-pneumatic suspension, hull and turret as well as the gun control system.
  • Mass production began in 1996 at the Indian Ordnance Factory’s production facility in Avadi, Tamil Nadu.

Features of the Arjun tank

  • The Arjun tanks stand out for their ‘Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS)’ ammunition and 120-mm calibre rifled gun.
  • It also has a computer-controlled integrated fire control system with a stabilised sighting that works in all lighting conditions.
  • The secondary weapons include a co-axial 7.62-mm machine gun for anti-personnel and a 12.7-mm machine gun for anti-aircraft and ground targets.

How is Mk-1A different?

  • The Mk-1A version has 14 major upgrades on the earlier version.
  • It is also supposed to have missile firing capability as per the design, but this feature will be added later as final testing of the capability is still on.
  • However, the biggest achievement with the latest version is 54.3 per cent indigenous content against the 41 per cent in the earlier model.
