TDC

Ok, about the automatic link from the UZO/periscope to the TDC. I can't give you the source; I read it some time ago and I don't recall details. My memory is that it was more procedure oriented than mechanical/technology oriented.

Based on what you quote, what tvre.org says, and what I remember, I'll go with the idea that there was a automatic link. However, I don't think it operated in real-time. That is to say, continuously; so to have a valid/updated firing solution a crewmember had to perform some action (press a button?) so that the TDC would receive the new input. This would have to be done on command, or else how would he know the skipper wasn't just looking to see if there were any escorts nearby.

I would not say it was done automatically, just that they were mechanically linked. In any case, it doesn't make sense to me to have the bearing automatically fed into the TDC all the time, as the UZO/peri. would be rotated a lot in normal searching to maintain situational awareness, and to have the TDC always fed changing bearings might 'burn up the gears', so to speak.
