Doesn’t have to go into the Dragons lair. China can’t track a nuke in the Pacific and won’t be able to for some time.
They probably can’t track a sub 500+ km from their coast either.
A short fast run into firing range of coastal targets should be pretty safe.
The actual patrol zone could be out in the Pacific 2000+ miles from China.
Here is the problem with India, they cant build a road let alone a good submarine.
It’s not that they are stupid, it’s just weird politics.
India is an odd place that can not get shit done because they adhere to democracy. That is punctuated with violence.
China is on the rise because they roll over all that stuff.
The road goes through your family farm.
Violence punctuated with democracy.
