Heh, just upgraded my hydrophone and didnt have the required renown. Makes me mad as on my first patrol I saw the HMS King George V all by herself (may have been the Aston) in a firce storm. Before I could get to a good firing position she spotted my conning tower in the trough of a wave and fired a round at me before going full throttle and leaving at 20+ knots. Will always be remembered as the one that got away
Thanks for the help.
