Immersive techniques for the true subsimmer!

[bstanko6]

Wanted to say thank you to all the subscribers to my YouTube channel. You guys are making it bigger and better. It tells me that I taught you guys something crucial in this wonderful game!

I can’t believe they’re only a number of years ago I started making these videos and now I’m looking at all the videos I’ve made and all the wonderful comments.

It’s getting harder to figure out what else to make a video on! Hence the reason I been away.

If you guys have any ideas of what videos I should make next for you please let me know. I will let you know if I’m able to make that video or not if I have the knowledge to even start a video.

Just let me know!

Congrats on hitting 1k

[bstanko6]

Thank you I really appreciate it

Really interesting stuff here, still going through all the videos. No longer using the periscope when travelling 5 knots or more and learning the 4 bearings method! Thanks everyonie esp bstanko and tonci87

[bstanko6]

Glad we can help enhance your game!

What I wish we had is Vorpostenstreifen, the patrol lines set up by BdU north to south. He would even tell boats “travel x degrees at x knots til further notice”.

We are way more on our own in these sims than they were in real life. BdU dictated their every move in most cases. It would be nice to get more orders like that.

True, almost every movements and actions of U-Boote on patrol area were micro-managed and dictated by B.D.U. In addition, Kaleuns weren't really enthusiastics about "hunting freely" on locations.
About ""Vorpostenstreifen", if found this passage in "Convoy S.C122 & GX229 : Climax of the Battle of the Atlantic, March 1943" by Martin Middlebrook.

The distance between U-boats in patrol lines was about twenty sea miles [...] A Gruppe that was sweeping forward to meet an expected convoy was an "Aufklärungsstreifen" - a "reconnaissance" or "patrol line" - while a Gruppe that was ordered to remain static on a given line became a "Vorpostenstreifen" - an "outpost" or "picket line".

U-boat men much prefered to be in one of these lines than on the "free manoeuvre" type of operation in wich a boat was given an area of ocean and left to search for targets in it [...] We were always very pleased to get the order from B.d.U. to form a patrol line, we knew from experience that this gave the best opportunity of finding a convoy. We put the best men on look-out duty; very often there was a bootle of champagne or cognac on return to harbour for the man who made the first sighting. Morale reached the depths when storms or rain blotted out visibility and went even lower if the sweep went on too long without a sighting. (Käpitänleutnant Kurt Baberg, U.618)

Got to admit I hadn't been around much or playing sh5 don't know maybe do videos doing a historical campaign from start to finish

I encourage anyone visiting this subject start at page 1. Full of great stuff from many individuals here at Subsim!

The “Mehrfachschuss”:

One of the three types of firing (besides single shots and fans) was the “Mehrfachschuss”, or multiple shot. This type is very little known, and so if you want to use it the way the Germans used it, I will lay it out. In the game it is easy enough to just shift the point of aim to different parts of the target in rapid succession, but if you want to simulate how a shot like this was done in real life, here it is. This differed from “Einzelschüsse”, which were single shots that were individually aimed at separate targets.

You can see mention of this both in the commander’s handbook (1) as well as the British report on the captured U-570 (2):

(1)

“171. To the extent sufficient torpedoes are still available, multiple shots (double or triple shots) should be used against valuable targets, even if at close range and with reliable shooting data. All shots should then hit, the purpose being to destroy the enemy with certainty. In doing this, the shots should be fired by shifting the aiming point on the target.”

(2)


How -
The gist of it is you fire what is effectively a longitudinal spread, either two or three torpedoes all on the same bearing, at intervals of 8 seconds. This interval insured that torpedoes did not interfere with each other when firing MZ and also made it easier on the man at the firing switch box in the control room.

For a Mehrfachschuss of 2:
You take the target speed and multiply it by 2, and then shift your aim point that many meters forward of target center. Fire, wait 8 seconds on same bearing, fire again.

As an example, say the target is going 16 kn. In 8 seconds that target will travel about 65 m. You take 16×2, which is 32, so shift your aim point 32 m forward of the target’s center. You fire, and by the time the 8 seconds are up and you fire the next torpedo, your aim point should be somewhere in the aft half of the target, providing a nice forward/aft dispersion so both hit.

For a Mehrfachschuss of 3:
Same as above however you would just multiply the target speed by 4. In the example above, you would have shifted your aim point about 64 m forward, and so in 8 more seconds, your aim point is then center mass for the second torpedo, and then aft for the third.



The Germans used this for firing on good data when they wanted all two or three torpedoes to hit to ensure sinking. They used fans (“spreads”) to ensure one hit (on bad data), as the handbook lays out.

If anyone ever needs me to dig up a video for them to help them out to learn how to play this game please do not hesitate to ask. I’ve made many videos on many subjects about SH three and five and I’m more than willing to help you find whatever you need.

Hello, thanks for all the tips, I have read that with great interest. I do have a question as a player playing full immersive. How do you remove or hide the alert for shallow waters or the alert when your sub is close to the bottom of the sea?
I find it really not immersive :-/

Thanks

edit : And another question. I never used another setting than impact for my torpedoes. How do you set your torpedoes (impact or magnetic) and wich death ? I would really appreciate your point of view, thanks again

[bstanko6]

Rosco, I have an old version of TWOS, but in the upper right hand of the screen there is a button for shallow depth alerts. Click that off.

Here is my video on torpedo settings:



Hope this helps!

[Rosco74]

Thank you I will check that button, strange I've never seen it before, I am on the last version of TWOS.
And thanks for this video, very nice I learned some nice tips
