Type VII Interior Tour Series

Matt! some questions about the CR video 1

43:50 you say the night scope could elevate higher?more? that the attack scope; does that mean the night scope could raise higher than the attack scope? Or it could tilt the view to scan more straight up and away from the horizon? Right now the night scope in WP does not raise as high as the scope above it in the conning tower.. so, I'm interested in knowing this, thanks.

Hi Neal, yeah I realize I wasn’t entirely clear about that in the video. It could be angled up higher, up to 90°, whereas the Standsehrohr only could go up 20°.

In terms of extended length, the C/9 NLSR had a length from ocular to exit lens of about 7.5 m, and the attack periscope about 7.8 m (at full extension) so it is appropriate that you need to go a bit shallower to use the NLSR given that the height difference in the boat of the respective oculars is greater than the 0.3 m length difference.

Ok, good deal, thanks.

Another question, if I may: 49:30 that TBT link for the night scope, is there a separate one for the UZO and attack scope?

Yessir. The attack scope one was mounted on the scope itself on the backside (opposite side of where the operator sits). The UZO one is inside the UZO column itself.

@derstosstrupp, thank you for the reply. Oddly, the Norwegian cream color is fairly close, as the original German requirements, specified the RAL color, and called for Ivory. I agree, that stated, the incandescent color temperature would warm it still a bit more.

@Nimmo55, the translated colors for the deck are here, too:

Last two questions:

Ready lamps, 5 of the them, two rows: are they lit when it is safe to dive?

Starting the diesels, they could start them with the e-motors, was that the normal method or was it more routine to start with air?

Oh, and you said there should be 3 hydraulic resevoirs next to the attack scope well,

is that 3 with a non-snorkel boar?
Or 3 with with snorkel or non-snorkel?

I thought the 3rd reservoir was for a snork-boat, the non-snork boats had 2, 1 for each scope...?

thanks!

Correct, they are lit when ready/safe. In the case of the hull valve section, they light up when the electric sensors on the respective hull valve wheels detect that they are shut. In the case of the dive ready lamp section, they light up when the heads of the individual compartments flip the switch in those compartments that their compartment is ready for dive.

It was normal to use the e-motors to start when traveling in diesel-electric mode, which was used for much of the patrol. This is traveling on one diesel used for propulsion, that diesel turning its prop and also the motor on that side as a generator to generate power for the other side’s e-motor, which is turning the other side’s prop. Since they would have the other side’s motor running in this configuration anyway, to save on compressed air, they would simply start the other diesel with that E motor when they switched out the diesels every four hours or so in order to grind the exhaust valve seats.

Based on what I have seen in early type VIIC design documents, it was always three. For instance here is part of a schematic from the Bootskunde für VIIC from 1940:



Same for the U-570 Skizzenbuch diagram for hydraulic system (earlier-war VIIC):

Is/was the new battery meter some kind of remote hydrometer in the real uboats?

[BrendaEM]

@derstosstrupp, what an excellent treatment on the the TDC. I didn't want to comment until I was able to listen to the whole thing.

I have 2 really hard questions. They are better left until the end of the series.

1.) What are your favorite 10 things that Wolfpack got really spot-on with the simulation-game?

2.) Given that: the team has deadlines, limited resources, and compromises must be made to make the game playable for playability (such as the TDC/ladder conflict)—what are the 10 most important changes that could be made to Wolfpack to make it: even more historically accurate, more enduring on the market, and that would the greatest effect on gameplay.
