So people saying ATAGS dead because of <15ton asked by IA.
ATAGS has problems, and not just the greater weight. And is frigging expensive.
Right now, only imported guns are doing well. The ATAGS has issues, Bharat 52 doesn't meet some requirements and Dhanush has seen quality issues during production, which OFB claims to have fixed now. M777 is also facing some problems because we don't produce most of the parts in India, so it needs full Indian production. Only K9 has seen success, along with Sharang and Bofors. The IA wants many more Sharangs and the existing Bofors upgraded to 45 cal. Considering all of this, the cancellation of ATHOS has been extremely detrimental.
I don't think ATAGS is dead. It could go the Arjun way, or the IA will wait for further fixes before placing bulk orders. The fact is the IA needs far more than just 1600 towed guns. ATAGS is also available in MGS form, where weight and electical power are lesser issues. So even this requirement can easily climb above the current 800-900 guns.
