What It Is

The Advanced Towed Artillery Gun System (ATAGS) is India's indigenous 155mm/52-calibre towed howitzer, designed by the Armament & Combat Engineering Systems (ARDE) laboratory of DRDO in Pune, with the KAILAS gun carriage developed in collaboration with the Indian Army. The ATAGS represents a major breakthrough in indigenous artillery capability, featuring a 52-calibre barrel providing a maximum range of approximately 48 km with Indian extended-range full-bore/base-bleed (ERFB/BB) ammunition — among the longest ranges of any towed howitzer in the world. The system incorporates a semi-automatic loader, computerised fire control system with inertial navigation and GPS, and can be operated by a reduced crew. The ATAGS was selected by the Indian Army and approximately 300 guns were ordered following cabinet approval in 2023 at an estimated cost of ₹3,364 crore. Production is being carried out jointly by Bharat Forge (Pune) and Tata Power Strategic Engineering Division. The ATAGS fills a critical gap in Indian Army artillery, which has operated without a new indigenous towed howitzer since the Bofors controversy of the 1980s. The system has undergone extensive trials including in desert and high-altitude conditions.

FAQ

How does the ATAGS compare to the K9 Vajra-T?

The ATAGS is a towed 155mm/52-cal howitzer (18.5 tonnes, towed by truck), while the K9 Vajra-T (def-016) is a self-propelled 155mm/52-cal howitzer on a tracked chassis (~47 tonnes). The ATAGS offers comparable range (~48 km) at lower weight and cost, making it more deployable in mountainous terrain. The K9 is better suited for armoured/manoeuvre warfare. Both fill different operational niches in Indian Army artillery.

Sources: [1]

What is the range of the ATAGS?

The ATAGS has a maximum range of approximately 48 km with Indian ERFB/BB (Extended Range Full-Bore / Base-Bleed) ammunition. This is among the longest ranges of any towed howitzer in the world and exceeds the range of the M777 (24–30 km) and Bofors FH-77B (24 km) currently in Indian Army service.

Sources: [1][2]

Why is the ATAGS significant for India?

The ATAGS is the first fully indigenous towed howitzer design and production programme since the Bofors controversy of the 1980s effectively froze Indian artillery modernisation for decades. It demonstrates India's capability to design and produce world-class artillery systems domestically, reducing dependence on imports for a critical battlefield capability. The ~90% indigenous content target further strengthens the domestic defence industrial base.
