Real Submarine Technology & History Q&A

Good. I'll lead off with a question that you might not be able to completely answer. In Clear the Bridge, Dick O'Kane mentions setting up the PK and when he's happy with the solution, he sets up for a constant bearing attack. He points the scope at the shoot bearing and turns the bearing crank backwards to stop the bearing. However the AoB keeps updating and the speed of course, remains the same. This way he can shoot as juicy parts of the target cross the wire.

All this implies that there was a direct connection between the periscope bearing and the TDC, such as modeled in the U-Boat for SH3 and SH4. In addition, Nisgeis has reported that such an automatic TDC input from the periscope did exist.

What do you know about all that? And do you know if it was there in WWII?
