Afaik army said just they need an Armata like Indian platform. Some experts said at that time that Armata can be a good case study for India's own development. And that's for entire FRCV not just for FMBT. I don't know they ever mentioned T-14 perticularly. Even T-14 is much heavier (around 60T by Russian defence posts,claimed a Quera user, personally I have no info) than is claimed. Besides it is longer thus need more space to move. So can't be used in urban gullies,or in mountainous terrain of India. For that T-90MS is quite perfect. T-72 Ajeya sees a recent third time (or second whatever you say) upgrade package. Will be equivalent of Russian T-72B3. So they will be in service till 2035 at least. NGMBT (as termed by DRDO scientists in their article,rather FMBT) has two prototypes on paper. But it need further study to start work practically. By the way,I don't want without enough experience work on FMBT / NGMBT starts. Arjun Mk 2, with 1500 hp & APS is enough . Now time to time they must be modified with better electronics,engine etc. When we will get better metallurgy,with same design, weight will be reducted. What we need most is good ammos. OFB rather concentrate on it.
