I am wondering about the details of the TDC. SH3 and SH5 unfortunately both got it wrong to an extent and left out one major detail which was a defining feature of the German TDC. Although the TDC didn't track the target per se like the American one did, There was a feature called "Lage laufend", which, when activated, automatically updated the Gyro angle to account for any subsequent motion of the U-boat. In SH3 and SH5, if you change course, you need to redo your inputs, a huge disadvantage that wasn't necessary in real life. It was a common tactic of the U-boat to shoot "im Abdrehen", "while turning", during a night surface attack to enable a quicker escape, a tactic which was made possible by this feature of the TDC.

Not sure how far along in terms of development of this aspect of the Sim you are, but would be great to finally see!
You are correct, and this is a feature that we have implemented. When the u boat is turning, the AOB (but not the heading or distance) values are updated.

Default Update 16


Improved character models! Now they are able to change between different facial expressions and blink.

Thanks! Glad you guys are using this man's tvre.org. It a shame he recently passed away, however in honor of him and his great work it sounds like the site will be maintained indefinitely.

Very much looking forward to this - keep up the good work!

I could be wrong here, but I think that tactic was actually used when shooting without TDC and with zero gyro angle. The necessary lead was calculated beforehand, and then the uboot turned to escape and let the torpedo when reaching the bearing to target needed for the calculated lead. This was also a tactic employed by torpedo boats (S-Boats). The reason for using it with no TDC is that it was a mechanical device, not a digital one, and as such the huge cascade of tooth-wheels needed some seconds to update the calculations after any change in the inputs. So shooting while the uboot was turning essentially threw off the solution and was not used.

That could very well be the case. What made me think that is I seem to recall reading Schussmeldungen where the shooting was noted as "im Abdrehen" and also noted that the TDC was used. I recall reading somewhere that the TDC had a feature, maybe in the later models, that you could set The turning speed of the boat, like "Rot 3" or "Grün 3" based on port or starboard rudder settings. As I think about it, it may have been from an excerpt from Schäffer's book about U–977. I don't have a copy of the book, wish I did, but I remember stumbling across an excerpt from it online where it was mentioned. I've tried to track that site down since but it seems to have been removed. That excerpt also had some interesting things to say about the Standsehrohr being a "technisches Wunderwerk", and its graticle having some kind of colored marks for different purposes. I've always deferred to your work on scopes, it's all I'll ever use, but I'd kill to find out more about these aspects from the book too.

Edit: See the link to Schußmeldung of J. Schepke below.
http://www.uboatarchive.net/U-100/KTB100-2Torpedo.htm

If you look at lines 22 and 23 of the report he did the shooting im Abdrehen (line 22), and on line 23 indicates the angle of turn and direction color for port/starboard as inputs, in this case "r 35" for 35 deg to port. At first I thought this might be the AOB, but that's on line 17. Line 14 has the same shot as being with Vorhaltrechner.

I would be interested in how that actually worked because it seems the computer could indeed compensate for a turn. An amazing piece of equipment that was actually not that far "behind" its American counterpart! And since our "TDC" isn't mechanical and since the devs have done their research and included "Lage laufend",we should be able to replicate this in Wolfpack it seems.

Default Great work, but...

Hi guys, I really do appreciate your work, but when it comes to lightning and colors it seems everyone doing a U-Boat sim is hopelessly spoiled by the (wrong) notion the movie "Das Boot" has spread among people. I have visited many submarines, including the infamous type VII and type XXI and many others. What they all have in common is the fact that they are NOT dark and grey inside, but white and bright due to the artificial light and bright paint job.
As much as I love the movie, it gives you a totally wrong idea of U-Boat interiour, since they had to build some parts larger than life to cramp in all the actors plus the camera and they painted everything in that greyish-dark color, which might be okay film.wise, but which is not realistic.

Cheers, AS

I think you hit the nail on the head with "lighting". Colour is, of course, a result of light.

Did the uboats have dimmer or red lighting for day/night ops and night vision preservation? I would have thought bright light below would have been horrible for something which made attacks on the surface in low light.

Also, i'm not sure about this, but I would have thought the lighting on preserved uboats would have been made brighter for spectating, do the museums record the changes from the operational colouring and lighting?

Certainly ships and tanks paint insides white, and the end brightness and colour would be as a result of the electric lighting only, in the absence of sunlight.

Hello everyone. It has been 5 or 6 years since I have logged in. Sh5 had just been released....Damn I am getting old.
Anyway looks like there have been many changes. Like others before me have said, I too am looking forward to the release of the new sim. The couple updates I have viewed it looks great. I will have to do a recurrent sub Commander school to redevelop my skills...lol
