The U-Boat and Kleinst U-Boat Project

Kapitän Schneider · 03-07-12, 05:55 AM

Ah yes the Type XVIII. Basically a slightly larger Type XXI with enlarged battery capacity. It's on my extended list, should really update my first post. Have to really finish and release my other subs first before I get to this one. If I ever do finish them

No, basically the same size and design (from the outside), with much smaller battery capacity - and Walter turbines instead

I'd still prefer the XXVI W

Kapitän Schneider · 03-12-12, 01:35 PM

Ah yes the Type XXVI-W. Does any coding genius out there know how to implement 10 torpedo tubes?

Dam you JayDee and you demand for one of the most advanced and heavily armed U-Boat's that I have come across in my research.

Not to mention all the different combinations possible for propulsion, when you have
- main electric motor
- "silent" electric motor
- Walter turbine
- main diesel engine
- diesel generator

You can run the boat (surfaced or while snorkeling) with the main diesel engine while using the diesel generator to charge the batteries... Or run the boat with the generator using the "silent" motor as propulsion, while main diesel + main electric motor are charging batteries... Or... Or...
You could even power the boat submerged with the "silent" motor while the Walter turbine charges the batteries via the main electric motor

Endless combinations...

Yeah, it's a nice little boat... Fast, nimble, the best sonar that would have been, packs a good punch with its 10 tubes, "folding" snorkel which was way better than the periscopic one on type XXI... And best of all, not just some fantasy somebody put on a sheet of paper, but actually in production at the end of the war. The soviets built it in the 50ies... That means, a XXVI W rear end with a modified XXI front. Project 617.

Ok folks I need some help. I'm currently working on the Turm of the Type XI U-Cruiser and now i'm stuck. I've been working from technical details and blueprints but it hasn't given me enough information to finish the Turm.

First of all there is this problem.

I have no idea what the thing circled in green is. At first I thought it was for the antenna, but if it is the housing for the antenna its twice the size! I know the compass among other things should go here, but if anyone knows or wants to have a guess and help me on this please leave a comment. Especially from you experienced Turm moddelers.

Second problem is circled in red. At first this is where I thought the compass went but there are two of them. I do have a blueprint of what is meant to be there but you can barely see it.
Reading from my U-boat book by Eberhard Rossler. Now I know its not rangefinding equipment as thats behind the periscopes. What they are meant to be are Quote: two special periscopes for artillery spotting.
I am a little familliar with Army artillery spotting binoculars, but if you see where they are located on the bridge, they are quite wide apart.
Agian of anyone knows what this is, please leave a comment.

It also says in my book, later the bridge was given a roofed surface-control platform with portholes, similar to those used in Italian and Japanese submarines. I've found barely anything on this, so do any of you know?

Here is the half finished Turm in 3d.

If anyone can point out where what should go that would help me alot. Before you point out where the UZO should go, the Type XI didn't have any, hence the Rangefinder and artillery spotting scopes.

So Information, Help and Advice appreciated please.

The area in green might just be a quick diagram to indicate the location of the dash-board. The crescent curve would be the wind deflectors while the dotted-lines would be the dash-board underneath. As seen from your first diagram.

Italian U-boat docked in Bordeaux.

This could be the roofed conning tower design mentioned in your book. You could just make out the rectangular port holes. It's also rather similar to some Russian subs.

As for the area in red, those might look closer to a pair of tank-artillery periscope. From what I know, some tanks were equipped with duel artillery scopes, not sure why though. However, it make sense to place two artillery periscopes for the U-cruiser considering that it is equipped with two large turrets.

These are just some theories, hope more would come up.
cheers,

Great idea for mod, looking forward to play it

Kapitän Schneider · 09-24-12, 06:58 AM

Sorry for the late reply folks.

Thank you Alpha Von Burg! This has left me scratching my head for months!

I think I can actually start to work out the conning tower, dashboard shouldn't be too hard. Have to look at some pics of Italian Subs with this kind of roofed conning tower with port holes.

The tank artillery periscopes might be a problem. Guess it's another case of googling pics again.

Any news about playable type XIV Kapitän Schneider please?

Lipud U-107 · 10-24-12, 10:01 AM

Rotor diameter: 7.31 m
Length: 4.42 m
Weight: 82 kg
Optimal rotor speed: 205 per Minute
Minimum prêdko¶ the air: 27 km / h
Operating speed: 20
range view, it in good weather: 40 km
use in battle: the U861 arguably the Indian Ocean near Madagascar.

Method of use: he had to be towed by a ship that had to have a speed of at least 18 in the other there was a problem with the start

more ship and info. next time

Alpha Von Burg · 03-24-13, 04:33 AM

Just thought this might come in handy. Its a development report on the type XI-B U-Cruiser you're working on.

Specific design specifications have been coped from the article under [III. T H E "B L A C K K N I G H T"] section in the article:

According to the official design drafts laid out for the German Type XI-B U-Cruiser in 1939, the specifications for this vessel were as follows:

Length Overall: . . . . . . 115 meters (377 ft.)

Breadth: . . . . . . . . 9.5 meters (31.3 ft.)

Depth: . . . . . . . . . 6.2 meters (20.3 ft.)

Extreme Displacement: . . . 3,630 tons.

Deadweight: . . . . . . . 6,800 tons +

Propulsion Machinery: . 2-shaft diesel/electric motors, (eight 12cyl. diesel engines in two separate engine rooms), plus two high-grade electric motors in third compartment.

Armament: . . . . . 4 torpedo tubes in the bow

2 torpedo tubes in the stern

6 torpedoes in ready-fire with

6 spare torpedoes carried below internal storage plates.

Above-Deck

Armament: . . . . . 4 127mm Guns in two twin armored turrets.

2 37mm AA mounted on deck amidships.

2 20mm AA mounted in after Wintergarten.

Ammunition Carried: . . 940 rounds total of 127mm.

4,000 rounds total of 37mm.

2,000 rounds total of 20mm.

(all carried in 3 separate magazines)

Crew: . . . . . . . . 110 men, with capability to carry an additional compliment of two company's' of "Special Coastal Troops", ('Brandenburgers')

Cargo Capacity: . . . . 600 cubic tons above provisions.

Accessories: . . . . . 1 One-Man "Arado/Argus 231" reconnaissance seaplane stowed in forward vertical storage tube.

.Cheers,

I don't buy it. For a start 26 knots is way too high for such a boat, it would have meant sacrificing underwater performance to the extent that it would be able to dive but not much else. WW2 submarine design had already to deal with such a delicate balance between surface and underwater perfomance that throwing in a substantial artillery armament, with its attendant requirements in terms of stability, supporting equipment, armor mass etc made the problem effectively untractable.
Improving one area could be done only by robbing perfomance somewhere else. Technology could help a bit but that would cost extra money and time.

Alpha Von Burg · 03-28-13, 05:32 AM

I agree that 26 knots might be a lot and that underwater speed would have been sacrificed. Then again, this boat would seem more fit for surface attacks than submerged attacks.

Also I doubt that a fully operational model was tested and achieved a result of 26 knots, its more likely that it was a test without the turret and ammunition on board.
