I've done a cursory search on the reasons of the failure of the ATAGS during trials. Except for a Financial Express article dated Sep 2021 quoting Lt Gen Chawla there's nothing of note worth citing here .
Even the article in question doesn't quote the General on the reasons for the failure except to state that the reasons have been conveyed to the DRDO with an anodyne statement on how the IA is all for indigenization & support for such attempts to pvt industry players in India adding that the IA wanted them to succeed.
However on the issue of Dhanush he was more forthright identifying production quality issues. I won't quote the article here as it's been linked here before & there's nothing revelatory in it . Besides it can be easily accessed on the net .
What we do know is when the ATAGS in it's present form was allegedly deficient in performance parameters , it was widely reported that the IA has asked DRDO to discard the electric drives & go in for the time & tested hydraulic ones which frankly is considered dated though not obsolete but has a range penalty . ( Hence any ATAGS vs ATHOS comparison ought to take this into account, if the information is accurate. )
Pls note there was no official communication from any of the princpals involved on the precise reason of these failures as can be expected in such cases but were purely speculations from defence correspondents & ex servicemen in addition to a few amateur defence enthusiasts or amateur experts as I label them .
An article from IRDW ( can't be linked here as the link is disabled by the administrators here nor does copy pasting work , I assume , for the same reasons. I'd encourage those interested to check it out on the net ) states that the electric drives would be heavier than the hydraulic ones where the IA has already flagged it's weight issues .( Hence any ATAGS vs ATHOS comparison ought to take this into account, if the information is accurate. )
Kalyani has offered to remedy the situation by incorporating titanium & other aerospace grade material in it lightening the weight but that would have a cost implication which as we well know is already on the higher side even as the IA loves to draw comparisons to the ATHOS. Apart from this , apparently there are also some recoil related issues. Other issues , if any , haven't been highlighted.
Incidentally there's the Kalyani groups Bharat 52 in the same category as ATHOS but the IA isn't interested. In any case by the time it's thru with trials , it'd be a decade I guess by which time some other innovation would have come up . Btw it's a decade since the ATAGS project was first launched . It was supposed to have been inducted in 2017 & then in 2019.
We can already see where this sorry episode is going & the parallels to Arjun if any , I'm sure , is purely co incidental. Incidentally the same Lt Gen Chawla DG Artillery states that the IA were impressed by the performance of the K-9 Vajra & the M-777 howitzers. No surprises on the statement here though it may come as a revelation to some that these are tried & tested products.
I hope someone makes the effort to check up on which Armies internationally have equipped their artillery with electric drives & how did they go about it .
Instead all we have are glib statements from renowned storytellers on why ATAGS failed . Source ? Here's it :
