I was actually ordered to RTB in my last patrol. I had run out of torpedoes, but sent a contact report on an enemy task force. I then received a pop up message saying something like "Excellent work, we will direct other assets to the target. RTB at your discretion."
Other than that, I usually RTB after about 2 months at sea. I can't imagine a sub crew would hold out much longer than that in reality.
