Your news is behind the times.Tracks and Engine are now built in india and indian tracks are better than the russian ones in fact .Engine was recently indigenized,its a copy.1500HP engine work in progress.Gun production is nearing completion for gun barrels for t-72 and t-90 which are better than older ones.Orders have gone to private industry(kalyani bharat forge and TATA who both have casting experience on arty guns) and private industry is not OFB loser.Armata may not happen due to no ToT and more importantly i'm not sure the no crew in turret system is proven enough for IA to mass adopt it.Yes the requirements in the RFI do point towards T14. The two issues with that are going to be Cost and ToT. India wants full ToT and local integration, Russia so far has not given any country full ToT for even base model T90S, india still has to import the guns, the tracks, the transmission and other things for it because Russia refuses to give ToT. So it’s unlikely they will give full ToT for T14. However if india is willing to make a compromise there and can come up with the funds, then T14 is a very formidable tank, one of the best in the world (granted the APS and ammo are purchased with it).
The RFI also states that induction is to start in 2030, and judging by previous Induction rates, will take over 20 years to complete the order of 1800 tanks. So it will be some time still before we see this in service.
The other thing to consider here would be the increasing closeness of india to the USA and how they might react to this sale in 2030. Or how Russia might react to Chinese pressure over this sale in 2030. Both of these might be a non issue or a major hinderance depending on how things are a few years down the line.
Regardless of all that, if a tank like this is purchased even in 2030, it will be a great capability boost to IA.
