Why on earth should they ping at all? They are subs. Secret service of the deep. Silent but deadly etc.
And don't tell me it was doctrine. Not in 68 for sure. Its just a bit silly.

Because the enemy is quieter than they are.

To take a point more to your side though, KFG might do well to come up with a passive only AI for when the "Soviet Campaign" goes active. Imagine the screaming when otherwise undetected American submarines give themselves away by active pinging.
