Arjun MK-1A

Date: 20 February 2021 Tags: Military


Prime Minister Narendra Modi had recently handed over the indigenously developed Arjun Main Battle Tank (MK-1A) to the Indian Army.



The Main Battle Tank is developed and manufactured by CVRDE and DRDO along with 15 academic institutions, eight labs, and several MSMEs.



  • 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 fire power, high mobility, and excellent protection”.

  • During the development, the CVRDE achieved breakthroughs in the engine, transmission, hydropneumatic suspension, hull, and turret as well as the gun control system. 



  • 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 stabilised sighting that works in all lighting conditions. 

Mk-1A upgradation

  • 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 percent indigenous content against the 41 percent in the earlier model.
