What Type of U-boats were U-799 and U-800 to have been? I can't seem to find them anywhere. TIA for any info.

Type XVII-K. But we're canceled before anything was done.

Type XVII-K. But we're canceled before anything was done.

That is what is listed in GERMAN WARSHIPS OF WORLD WAR II, by J. C. Taylor (1966)

XVIIK Germania Werft, Kiel
U.798 Not completed, scrapped
U.799 Cancelled
U.800 Cancelled


But both Groner, DIE DEUTSCHER KRIEGSCHIFFE 1815-1945, Band 3, and Rossler, THE U-BOAT state that only one Type XVIIK U-Boat (U-798) was ordered as an experimental type with closed cycle propulsion and make no mention of any further boats being ordered of this type. U-798 was laid down but never completed.

U-799 and U-800 are not listed in 'U-boats never laid down' in uboat.net

What types were U-919 and U-920? I can't find them on U-boat.net. Thanks for any info.

What types were U-919 and U-920? I can't find them on U-boat.net. Thanks for any info.

Again, GERMAN WARSHIPS OF WORLD WAR II:

VIIC Stuelcken Sohn, Hamburg

***
U.909-918 Cancelled
U.919-920 Projected

U-BOAT OPERATIONS OF THE SECOND WORLD WAR:

U 909 - U920 were never built, orders cancelled

Groner, Volume 2, English edition, for Type VII C/41

U909-U912: construction suspended

U-919 and U-920 not mentioned in Groner

I believe u-boat.net has access to a lot more sources than I have, so if a U-boat is not mentioned there, the U-boat most likely was never projected or ordered

[ijnfleetadmiral]

Thanks for the info!

[jbroshot]

Happy to have been of some small assistance

[ijnfleetadmiral]

Is there any info on U-943 through U-950? They are not on uboat.net. Thanks for any info.

And this note in The U-boat The evolution and technical history of German Submarines, by Eberhard Rossler, 1981 English version

"However, after the Supreme Commander-in-Chief of the Navy had decided in favour of large series production of the new Type XXI..., General Director Merker, the new head of the Main Committee for Ship Construction, suspended all work on the Type VIIC/42. All contracts were withdrawn on 24 July 1943." (page 160)
