How India lags China in submarine race

[Chinese-Dragon]

Wrong read the piece again.Clearly mentions it surfacing while passing through malacca.
'In fact, they passed visibly through the Strait of Malacca with other Chinese naval ships sailing to the Gulf of Aden.'
This refers to both deployments.You see this news report is latest from 20th july not old one.Check date.

Now onto second part.Yes they do have to surface often,unlike nuke subs.U can use AIP to increase time to 3 weeks at the cost of cutting down ur speed to 4-5 knts and take a very long time getting to ur target and increasing endurance load which is limited,and with no refuelling 1 way trip.
Finally don't really know why this is so difficult to understand,pakistan and thailand will operate these ships CLOSE TO THEIR SHORES from their home ports.AIP is perfect for these conditions,no large travel distances required.The reduction of speed with AIP means little here as submarines will largely lay in ambush against enemy forces in shallow waters,no need for huge distance travel which requires speed.Secondly if needed they can surface once maybe in 20-25 days near their home base and under friendly cover.They can also easily come back to home port and refuel.None of these apply for chinese diesel subs in IOR.Unfortunately u don't seem to understand the difference between long range and short range operations and why AIP is not much of use in former ones while very effective in latter due to speed penalty which is vital for long distance travel and ops with no base in the combat area,and second close to home shores.This is reason major navies use nuke subs for global deployments,proof is right in front of you.You can ask any naval specialist too.If AIP was the magic answer,there would be no point in building SSNs at 4-5 times the price.

So is this the 6th time I'm going to ask for that "video proof" you boasted about having?

Stop moving the goal posts. You quoted my post in the first page (about the Malacca straits) and made the ridiculous claim that our AIP diesel electric submarine would have to surface "OFTEN" in order to recharge its batteries before reaching the Malacca straits.

Then you claimed to have video proof of this. Where is it?

And since you're not going to give it again (as before), then can you tell me have you ever seen a map? Can you explain how it would take more than 3 weeks to travel from Hainan island Naval base to the Malacca straits? Seriously?

Granted I do not claim to be an expert on submarines as you are doing, but that doesn't mean you can make such outlandish claims (including a claim to have video proof) and just insult me until I accept it. How can it take more than 3 weeks to travel from Hainan island to the Malacca straits? Hell even a cross-Pacific Ocean shipment from an internet delivery doesn't take that long, and that's from the other side of the world.
