The Defence Ministry has placed orders for Main Battle Tank Arjun’s Mark-1A variant for the Army, which is manufactured by Heavy Vehicles Factory (HVF), Chennai.



Few months back, PM Modi had handed over the prototype Arjun Mk-1A to Chief of Army Staff General M M Naravane at a ceremony in Chennai.



  • The Defence Research and Development Organisation (DRDO) started developing the Arjun to replace the Russian-made tanks.

  • After the start and conclusion of trials of the tank, it was inducted into the Indian Army in 2004. The work on Mark 1-A variant started in 2010.

  • Extensive trial, including field trials was started by the army in 2012. The DRDO and army were both involved in the trial process.

  • About 14 major upgradation and 58 minor changes have been made in the Mark-1A variant of the tank from the existing Mark-1 version.

  • The indigenous manufacturing will boost ‘Make in India’ initiative in the defence sector and is a big step towards ‘Aatmanirbhar Bharat’.

  • Multi-layered robust protective armour named ‘Kanchan’

Other characteristics

The Mark-1A variant has more parts sourced from indigenous vendors. It has helped India reduce dependence on foreign vendors.



  • The acquisitions will increase the number of tanks in armoured regiment. Pakistani army has also recently acquired some Chinese origin tanks.

  • The tanks are aptly suited for desert terrain. It is more effective and lethal in comparison to existing tanks.

  • In some aspects these tanks have matched the capacity of Russian-made T-90 and in some they have outperformed them when pitted against each other.
