The ATAGS is a 155mm, 52 calibre artillery gun jointly developed by the DRDO in partnership with Bharat Forge of the Kalyani Group and the TATA Power SED.

In August, 2018 the Defence Acquisition Council had accorded approval for the purchase of 150 of these guns at an approximate ₹3,365 crore which would be split between the two companies. The deal will be split in 60:40 ratio between thee lowest bidder (L1) and L2.

Once the user trials are over, the Army has to give the Request For Proposal (RFP) and the initial lot can be supplied immediately, the official said. The Army requires 1,580 guns in this category and Israeli firm Elbit Systems was shortlisted for a tender floated to procure them.

It may be recalled that in September 2020, the ATAGS had suffered a barrel burst during trials which have since been stopped. A committee was set up consisting of DRDO scientists, Army representatives and OFB officials to determine the cause and submit an evaluation report.

An official was quoted saying that it certainly did not appear to be a design issue and the investigation will determine if it is an ammunition issue.
