In December 1942 the Allies broke the German Triton code. Two
things worked against them, however. First, unknown to the Allies the
German intelligence "B" service was decrypting the Allied convoy codes.
Working pretty much in the same manner as Bletchley Park and OP-20G, the
Germans were able to piece together a great deal of information about
the convoy system, including precise convoy timetable information.
My question is does the contact updates Mimic this information gathering or if not is this issue addressed some other way in SH3 .
Should i have contact updates on to be more realistic .
