28cm Kanone auf Raupenlafette

[Geertvdp]

can anyone give more info on this vehicle?


It is pictured on the inside of the cover of an Ian Hogg book, "German & Allied secret weapons of World War II"

the gun's is noted as "54.5 Kaliber", probably the 28cm L54.5 ship gun..

Title on the blueprint :
28cm Kanone auf Raupenlafette
Tarnbezeichnug R2
Gewicht - 136t

This is one of the planned self-propelled coastal defence guns for Kriegsmarine from 1939. Series was to include 14 different platforms designated from R1 to R14. Armament was to range from 150mm to 380mm and it was to be mounted on fully traversible turntables on tracked carriages. The series never left drawing boards.

Thanks for the info!
So in a certain way (purpose), this is related to the P-1000 project.

I presume this is a Krupp project?
Are there any other drawings available on this project, in other books?

Hi Geert

Here a other drawing of the R 2 from the
book German Tank and Antitank in W.W. 2
from E.J. Hoffschmidt and W.H. TantumIV

Great artisit impression !
Thank you very much for providing the scan. I might end up making a 3D model of this paper project after all !

Makes me think of the rusisian Oka 420mm.

a side question:
I know that a caliber gun length is the relation of the internal diameter to the barrel length.
In this case it would mean the barrel is 15260mm long, so this is an excellent way to scale the object correctly.

But how is a caliber length exactly determined?
is it the length of the gun without breechblock and muzzlebrake?

That would be an interesting series: 3D models of all the weird, foolish, and wasteful projects that never got off the drawing boards. Well, okay, the ones that would have worked, too! It would be nice to see what some of them would have looked like!

Hello Gentlemen

I am looking for Information, Drawings etc of the series of self-propelled coastal defence guns designed for Kriegsmarine.
according to a member (Martti), there was to be a series of 14 different platforms disignated from R1 to R14. Any additional Information, drawings etc would be greatfully appreciated.
Here is the link to the first question concerning these vehicles. with a photo.

Are you sure they were supposed to be self-propelled? It could be a design like the Soviet 203mm howitzer, which was also on a caterpillar mount, but without an engine.

If it were to be self-propelled, should the designation not be "28cm Kanone auf Raupenlafette (sf)"?

The scan shows an engine compartment ("Antriebsraum") on the right with the numbers of the proposed gears, and a driver's compartment ("Fahrerraum") under the gun. So it is intended to be selfpropelled. But as it is only a layout, they don't have to worry about correct designations.

@TimR,
your link loops back to this article. Please correct it.

The link loops back because I merged the two threads.

Thanks for the info.
