Come on, people. Use common sense, life gets much easier if you do that.
Tata/L&T made a prototype each with 55% indigenisation, followed by an additional one with 75%. This is the version that's been tested and these 4 guns are the only ones that exist today. Any number beyond 75% is just a roadmap. And this roadmap has to come via LSP and the IA's GSQR. So, based on the GSQR, they can then make new prototype guns with significantly more than 75% indigenisation.
Meaning, 95% or 100% don't exist. They are simply on paper. And once they do exist, they have to be tested all over again. Post which they can begin induction.
If the LSP deal goes ahead next year, or even the year after, it will take until 2026 to have them all. During this time they should receive a GSQR, followed by new prototypes and a new round of testing, which could take us to 2027 or 2028 or even 2029 before an order can be placed, followed by another year or two before serial deliveries begin. So that's 2030+.
Common sense, people, common sense.
