So the delay was caused by the lack of know how of MDL to absorb the techs and provide the necessary infrastructure (which DCNS officials stated in interviews too) and the fact that we see the first sub being ready now, according to the plan from 2012 after the problems was solved, should make it obvious, that the project was monitored way before the new DM came in and that the new MoD had nothing to do with it.
As I keep telling you, it wasn't all as bad as you or the public might "think"! Indian forces are doing pretty good, important upgrades (fighters, subs, transport aircrafts, tanks) were done to keep the modernisation on going, plenty of additional procurements (at least for IAF and IN) were passed and even the right policies for getting the privat Indian industry in the game were initiated by him. So the current government took over from a more than decent level, which is also why, a year without any major procurement, didn't made Indian forces any weaker.
In fact, policy change to invite privat Indian partners, which is the base of the Make in India campaign in defence and the tougher stand against DRDO, were initiated by Antony and now thankfully followed by the NDA government.
Just as his blanket bans were a mistake, it's a mistake to generalize and say everything was bad.
