TDC

I thought I would try to word this another way, not saying that anything RR said is wrong though.

There are two major differences between the German TDC and the American TDC. In my book one is a major advantage and the other is a disadvantage required to make the other work.

In the american TDC, the AOB is not coupled to periscope bearing. Moving your scope will not change the AOB. I increased size and bolded there because this cannot be stressed enough. The typical german method of pointing your periscope at 0 and entering the track angle then just point the periscope at the target to get AOB does not work. This is a disadvantage.

In the american TDC, the optional position keeper tracks the target and your own subs movements and updates the torpedo gyro angle in real time, even if you are not tracking the target with any sensors at all. Again, cannot be stressed enough. This is clearly a major advantage.
