Kriegsmarine - KM Ship Plans/Discussion

I wonder what Germany would had used the Zenker Monitor design if built.

You mean the I/35? am thinking Kriegsmarine would operate her like how they did with old pre-dreadnoughts, having a bigger punch are certainly worth it (the original purpose of I/35 was to use long-range 35cm bombard against French ports and their aging battleships something like that).
 
Yes I/35. Say two Deutschlands and two Monitors. Though 3-4x I/10 Heavy Cruisers would be the best value having good experince for the next cruiser design.

Beyond H-41, they're mostly speculated, you can look up here.

Thanks for the vote of confidence, Alexi. FWIW, I'm collecting some of the information gathered here for an eventual version 2.0. I have a couple of other projects in the meantime.
 
And are there informations about H-41 battleship, like armour scheme and etc.

I have found these blueprints on the disc you have on first page. I thought that this is H-40 B but the length isn´t right and superstructure is same as on H-39.

Left one is steam turbine powered design and right side is H-39/42, bigger than H-39 (close to H-41 size), there's one preliminary H-39 with 16x15cm guns (only data) in RM-6.

Do you think this?

That's gotta be fake. I don't think they mixed 12.8cm and 15cm even in their wildest designs.

There is 1 H-class design with x16 15cm guns though.

I've looked into page 31 of the RM_6_60 and can only find this, so can you guy show me the exact file ?

Early evolution of the Panzerschiff P - class: schemes of preliminary studies with 2 and 3 turrets of the main caliber and various armor options

The source of the preliminary P-class are founded in RM7 "Seekriegsleitung der Kriegsmarine" but its non digitalize, two more files mentioned about mysterious armored ship "F" plans and preliminaries (later into battleship "F").

Thank you. If it is deemed possible, I can post a part of the text from S.Breyer's book, "Schlachtschiffe und Schlachtkreuzer 1921 - 1997", describing the evolution of Panzerschiff P and subsequent Handelszerstorer projects.
 
Do you know anything about u-boots type XII,XIX or XX?

Type XII Large U-boat project​

A fleet U-boat design from 1938. 8 torpedo tubes, 6 at the bow and 2 at the stern, all below the CWL. This boat was to carry 20 torpedoes and no mines. The gun armament was to be the same as for the type IX boats. No contracts granted for these boats.

Type XIX freighter U-boats​

Designed by the OKM from the XB plans in late 1942. Those large vessels were nor armed with any offensive armament, only AA guns, as they were only for transportation of material. Those plans were preliminary for the type larger XX U-boats and no contracts were awarded.

Type XX freighter U-boats

Designed in 1943 by AG Weser and the OKM (German Navy High Command) as transport U-boats to carry material from the Far East. They were based on the type XB mine layers. They could carry 800 tons of material and they had no torpedo tubes and no deck gun, only AA armament. They were to have a crew of 6 officers and 52 men. 30 contracts granted, 15 to Deutsche Werft in Hamburg (U-1601 thru U-1615) and 15 more (U-1701 thru U-1715) to Vegesacker Werft in Bremen-Vegesack. Of those 30 contracts only 3 (U-1701 thru U-1703) were continued after 15 Aug 1944, but none was completed and their construction was halted in early 1945.

About the H-39/42 design i replied last months, it's possibly the redesign of H-41 battleship.

Thank you for answering. I found these shipbucket drawings of type XII, do you think it is realistic?

Hi Alexi.

Yes, I agree, this sounds like the 15 Nov 1941 redesign that Dulin & Garzke mentioned. (pg 320)
 
Do you have this blueprint of Europa in one photo or without the right pillow? I want to make model of Europa and I need to print the blueprint.

Hello everyone.

I plan to post a series of pictures of German destroyers and rangefinders. These pictures are screenshots and photographs of line drawings from many sources (Z-Vor, Marine-Archiv, etc) (not copies of 'real' photos taken of the destroyers - yet). There are several dozen images in total and were taken at the request of Tzoli. I figured since I did all that work, it might be good to further distribute. I'm not sure who it'll really benefit or why it would benefit them even if it did, but I'm sure someone will find them interesting. They are mostly Type 1934-1936B destroyers, FuMO 24/25 & FuMO 63 Hohentweil-K and Flakleitgerat M42 drawings with some Flottentorpedoboote sprinkled in there.

Of slightly more interest, I am sure, is that I also intend to upload plans of various German destroyers (1934A and 1936 mostly, but these two classes are the most representative anyway).

This will not happen for at least a week, but the intention is there.
As usual, I will post again when everything has been good and uploaded - links included.
Thank you for your time.

Today I learned that Scharnhorst's overall machinery plant is rather small when compared to Derfflinger's, and that if you reduced the amount of E-Werke rooms you could fit Graf Zeppelin's machinery in the space.
 
Any idea how to access Krupp Archive files?, i have hard time to navigate the site.
 
Bummer, looks like there are none digitalize free files or unless am missing something.
 
Can you help me to understand the aft section of Europa. Do you have any blueprints only of this part? I don´t know if it is only like narrow bridge or are they big platforms.

The top one is an extension of the 'A' deck that forms the roof above the aircraft hangar. The second looks like the beginnings of a B deck - but that would run through the hangar bay, and it isn't included in the line drawings depicting the final plan. Instead, the extension of the A deck outside the rear of the hangar bay forms the covering for a small boat - possibly 2, side-by-side.

Thank you, but on picture I send those extensions of deck are covering whole aft or are they only gallery?
 
I am going to have to assume they cover the whole deck if they are an extension of the A deck, which also likely covers the entire width. I cannot say with any certainty, but it would only make sense.

Also note that the flight deck supports do not come all the way down, meaning it must be pretty wide overall.

Is there any reason why some German Carrier designs had the superstructure and funnel on the Port side and not the starboard side? I haven't really seen a vivid reason to this.
 
Likely the same reason as on Hiryu and Soryu and Akagi and Kaga to be used side by side with aircraft recovery from opposite rotations.
