India's state-run Armoured Vehicle Nigam Limited (AVNL) has unveiled the Arjun Mk-1A main battle tank (MBT) at Defexpo 2022, held in Gandhinagar from 18 to 22 October.

According to AVNL, the Arjun Mk-1A has been designed and developed indigenously by incorporating numerous improvements over the Arjun Mk-1 MBT, which is in service with the Indian Army.

The modern technologies fitted onto the Arjun Mk-1A give it an edge over other contemporary battle tanks, said AVNL. The new MBT is fitted with a computer-controlled integrated fire-control system incorporating a ‘day-cum-night' stabilised sighting system that guarantees a “very high first round hit probability“ and reduced reaction time to bring effective fire on targets, said AVNL.

To enhance firepower, AVNL also equipped the Arjun Mk-1A with commander's panoramic sight, an Mk-Il automatic target tracker, a remotely controlled weapon station, and a muzzle reference system.

AVNL added that the Arjun Mk-1A is referred to as a “desert Ferrari“ because of its “mobility characteristics that have proved [their] worth while operating in highly demanding Indian desert conditions“.

The Mk-1A has low ground pressure, a high power-to-weight ratio, and a high-performance power pack, including a “robust“ transmission system that helps increase its mobility capabilities, said AVNL.

Other technologies fitted onto the Mk-1A include an advanced running gear system, a new final drive unit with increased reduction ratio, a new track system, a driver's night-sight system, and an advanced land navigation system.
