Yeah. IDDM means an Indian company can collaborate with a foreign company using their systems. They need a proper roadmap for indigenization, including software.
This competition is for ATHOS to win, they are providing up to 100% ToT, and Adani is the Indian partner. The closest competitors are Dhanush and Bharat 52, but I don't think they are advanced enough, at least Dhanush, in terms of computers and networking. There are other European competitors, but they are expensive, including Bofors.
In any case I don't think there's gonna be a cheaper and more advanced gun than ATHOS. It costs 10.7Cr versus Dhanush 45's 14.5Cr, not 52 cal. ATAGS is over 20Cr now. Bharat 52 is up to 14Cr.
They have a certain interpretation of dpp2020.
