I track boomers a fair bit, your best tactic is to be slightly deeper and to one side but behind if its american SSBN your tracking, if its russian then go ahead of it by about 2nm.
Never ever stay at the same depth as the enamy submarine if it turns you have little to no chance of stopping yourself and turning, if your below him he can ride right over you otherwise your going to slam into him (if your behind).
I will generaly track american boats from the rear to the left hand side about 600 yards - 1000 yards behind where all three of my arrays can hear him and i have a good HF visual.
A boomer traveling at 15 knots is totaly blind and will make so much noise you might as well put a massive arrow saying here i am on it. most boomers i track will generaly not go above 8 knots unless 1) fired on 2) they detect you.
its even harder to track under ice as you then have a massive new problem, in all ive only tracked 2 ohio class SSBN's sucsessfully 1 vangaurd class (SC) a few french boats chinese xia and a han and a fair few others but where i normaly play its only me and other SSN's.
if you want a MP game on it then PM me
