ATAGS is fully indigenous towed artillery gun system project undertaken in mission mode by DRDO as a part of artillery modernisation programme of Indian Army. Armament Research & Development Establishment (ARDE), Pune is the nodal laboratory of DRDO for design & development of ATAGS along with other DRDO laboratories. The Armament system of ATAGS mainly comprise barrel, breech mechanism, muzzle brake and recoil mechanism to fire 155 mm calibre ammunitions held by Indian Army with a longer range, accuracy and precision and provides greater fire power.

ATAGS is configured with all electric drive to ensure maintenance free and reliable operation over a longer period of time. It will have a firing range of 40 Kms with advanced features in terms of high mobility, quick deployability, auxiliary power mode, advanced communication system, automatic command and control system with night firing capability in direct fire mode.

The development trajectory of ATAGS aims at establishing indigenous critical defence manufacturing technologies with the active participation of Ordnance Factories, DPSUs and Private industries including Bharat Forge Limited, Tata Power Strategic Engineering Division and Mahindra Defence Naval System to meet the aspiration of Make in India initiative in defence sector.

DRDO is committed to develop and field ATAGS in the shortest timeframe with active participation by leading industries to meet the requirement of Indian Army. The first fully integrated gun system will be ready for user trials by early 2017.
