"How such sub will be mission killed?"
I am no expect, but I believe 'mission killed' doesn't mean the submarine is sunk, but that it is not in a position to launch it's missiles, as that is its primary mission, and it can't carry out that mission, it is mission killed. It can't launch if there is a SSN in the area, to do so is suicide, or if travelling too fast, I think less than 5 knots.
"Large noisy target... common. Any sub what will try to follow will be exactly as noisy."
A submarines primary passive sensor is located in the bow, if the SSBN and the following SSN both are doing 15 knots, surely the noise of the reactor pumps, prop cavitation, etc will make it difficult for the SSBN to detect the SSN behind it, while the reverse is true for the SSN. I'm not a submariner, but it seems logical.
And then again - how it is easy to track SSBN under ice?
No idea, but to hazzard a guess, a SSBN has a maximum dept of say 2000, in the open it can be anywhere in that water column, hiding in thermals etc. Under thick ice, which extends mostly underwater, its ability to hide in thermals will be greatly reduced, there may not be a lot of water between the berg and the bottom. Would the ice act as a reflector of any noise emmitted from the SSBN. Now I am curious, must do a search lator.
I think our friend has read a few books, listened to a bit of propaganda, and casts himself as an expert.
