I have some remarks to realism of type XXXI in silent hunter 2 which could be improved.
I have read the book from Eberhard Rössler about that type and I found some interesting things.

It was possible to run with schnorchel up to 6 kn and (!) 9 to 10,5 kn.
Between 6,5 to 8,5 kn it was not possible because of vibrations.
Activating time of schnorchel: 2min 40 s
Deactivating time of schnorchel: 1min 30 s

It was not possible to use the periskope above 8,5 knots because of vibrations.
A brandnew accoustic weapon called "Nibelung" was build in for aiming without periskope:
Range 5 to 10 km
Accuracy: 0,5 degrees
It offered speed, distance, course

Counter measures were available (Bold 4 and 5) making hydrogen bubbles. Bold 4 was used since 1944. Bold 5 was new and could be launched from 200 m depth.

This u-boat never sank a ship or saw action, apart from an alleged dummy attack after the cease fire order had been issued.

It should only be included in 1945 to simulate an early release.

'Neiblung' was an active sonar set which could measure very accurately dopplar shifts from a targets echo return. After 3/4 active pings it could work out target range, speed and course. This info could then be fed automatically into the torps for firing. A further refinement of 'neiblung' was called 'sarotti', a PPI (Plan Position Indcicator) display of the sonar returns. Not only that but the Gremans planned several new and highly advanced sonars for the Type XXI (and any further U-Boats). I don't have the details in front of me now (i'm in work ) but they composed of a listening sonar which used the angle at which sound arrived at its array+the time delay between sound arriving at each individual element to measure distance and range to a target (this is an early version of PUFFS or its modern equivlent WAA). 2nd was 'SP-Gear' a very accurate passive sonar for ranging for the 'Hecht' defensive rocket torpedos. 3rd was 'Erda' an active 'intercept' array to show transmitting active sonars and their relative bearing and strength. 4th was specialised 'own-noise' sonars to detect and characterise own ship generated noise. 5th was 'Dorsh', a towed array passive sonar. 6th was 'Kav' a device for determining acoustic conditions and thus average detection ranges based on know allied soanr frequency's (actice and passive). 7th 'Argus' which seems to be some kind of non-acoustic sensor for detecting electrical and magnetic fields given off by ships. 8th 'Kastor' a high frequency sonar for mine avoidance/hunting.

So you can see that if the Type XXI is available then it should be fitted/upgraded with this equipment to make it a true underwater hunter. There are also loads of other equipment fits planned for the Type XXI, specifically advanced torpedo's, radios for underwater use 'Horing' and 'Aal' and an advanced 'gertrude' underwater telephone called 'Steingraf'.

I'd like to see the introduction of the Type XXI handled like it was done in AOD, i.e you can specify in the campaign options if it becomes available historically (i.e you can only get it in 1945) or you could specify an earlier introdiction, maybe early 1944 for example. Also when you are assigned a new boat there should be an option for training missions in the Baltic to 'work-up' you and your new boat (though you should be able to 'skip' them if you want to plunge straight into the action).

As a departure from the normal game (whatever that turns out to be) ya know how some movies have "special features"? Well SHIII could have an alternate ending for the XXI.......allow it to continue past the end of the war as a survival-rogue U-Boat type of game. Instead of sinking ships you have to get them to stop so you can steal their fuel and stores to resupply. Once your supply of torps runs out..you get no more. But, it is a big world afterall so hiding out with one XXI couldnt be that hard, or could it? LOL

Frank,

That sounds like a pointless excercise to me. If i get the Type XXI in a campaign i want to use it against allied convoys, not fart around after the war like a later day pirate.

[Gian]

I definately think that they should have the XXI in there as it is a dynamic campaign. Otherwise, I hope if will be included for the custom quick mission generator. I hope they will have it in there just like they had it in SH2

That is a must have!!!!!!!

Cheers

As long as it isn't like CAOD where i got command of a XX! in March '43. Almost doubled my career tonnage in one patrol!

[Henric Edwards]

What about the Type XXIII? It managed a few patrols and even a couple of sinkings. It was small, but it would still be cool to have it in the game.

[Sniper_1]

All,

And while we are at it, why not a Walter U-Boat?. The Germans were buliding a series of Walter Boats at the war's end, the Type XXVI with 10 torpedo tubes and a single walter turbine for 20+ knots underwater preformance. I'd like to see Walter boats allowed by the source code so that even if the subs are'nt in the game, they could be modded.

[cdragon]

Wire-guided torpedoes would be welcome, too.
