Indian Army’s massive new firepower addition tomorrow; K9 Vajra howitzer guns will meet requirements of 21st-century warfare
Three decade wait will be over when the K9 VAJRA-T 155mm/ 52 calibre tracked self-propelled howitzer will be inducted in the Indian Army arsenal on Friday. The gun has been developed and built by a private sector company by Larsen and Toubro (L&T) and South Korea’s Hanwha Tech Win (HTW).

The K9 Thunder development programme started in 1989 and the first gun entered service with the South Korean Army in 1999.
The private sector company had won the bid in May 2017 to deliver 100 howitzers at a cost of nearly Rs 4,500 crore under the government’s ‘
Make in India’ initiative in 42 months. The guns have over 50 per cent indigenous components.
As has been reported earlier by FE Online, under the contract, L&T brought 10 K9 VAJRA-T from South Korea and the remaining 90 will start getting produced at L&T’s Strategic Systems Complex in Talegaon near Pune. This project has been fast tracked to ensure that Indian Army’s modernisation programme.
