AIP is 2 weeks without recharge, that is very relevant in Pak v India war.....I already said about endurance! I also said about technology as you are claiming that A90Bs is far and more sophisticated than IN Scorpenes.
The same claim I can make that an upgraded kilo submarine is far and more sophisticated than your upcoming new subs.
But, The only fact is that Scorpenes is one generation ahead to A90Bs. Technological one of the advanced present available submarines.
AIP does not make difference in India and Pak WAR scenario. Kilo-class sub endurance is around 60 hours without a recharge..
