Vijayanta, first India-made millitary tank which was handed over to the Army, was manufactured at Avadi Heavy Vehicles Factory at Madras.
The Vijayanta was a main battle tank built in India based on a licensed
design of the Vickers Mk.1. The Vijayanta was the first indigenous tank
of the Indian Army. The prototype was completed in 1963 and the tank
entered service in 1965. The first 90 vehicles were built by Vickers in
the UK. Production continued at the Heavy Vehicles Factory in Avadi
until 1983 with 2,200 units. A number of the tank hulls were converted
to other uses such as self-propelled guns after being withdrawn from
service. The Vijayanta has been supplemented by the T-72M1 in Indian
service.
