Marinekleinkampfmittel "MANTA"

[moin1900]

Hi everybody

I have found a very unusual Project from the Germans in 1945. It should be called the "MANTA"
It should be a Submarine-Catamaran-Glider designed by Hellmuth Walther.
Able to drive on land, drive at high speed on water and also to submerge .

SOME DATA
length: 15m, breadth: 6m , displacement: 50t
engine: 2x 800 PS Walterturbines
2x 25 PS Electric Engines
speed: 20kn with airfoils 50kn
30kn underwater
Crew: 2 crew members

Here is a Picture

Are there any other Pictures ?

Thanks in advance and many greetings

Fourthly , the existence of tracks from midget submarines
supported the conclusion that the Warsaw Pact was responsible for the
intrusions. It would, according to the Defence Staff Report, be ‘almost
impossible to keep such systems secret in the West.’82

This is from the following document

and here is a picture from the link you posted above

Hmmm ... I wonder

Hmmm...
I made an AutoCAD drawing of the MANTA a year or so ago, but abandoned it due to more pressing matters. Let me look through my archives for the drawing and I will post it sometime next week as a PDF.

Hi everybody

Maybe a stupid question ! How many gliding surfaces are located between the side keels ?
I see three ? Are there four !
Please look here

Hi everybody

Somebody knows this ? It would be very helpful!

Interesting stuff, moin1900. I suspect that the wheels were to allow handling ashore and launch via a slipway - they wouldn't have been much use on the seabed! It might work quite well as a single-purpose coastal defence craft.

Might those keels be sound attenuators?
Whatever the noise the main body of the sun makes…flat surfaces can cancel out…or allow communication up above:

Researchers realize water-air acoustic communication based on broadband impedance matching

With increasing demand for exploration and utilization of marine resources, achieving direct and efficient communication between water and air has been an urgent need. Sound waves, as the only propagation way with low attenuation in both water and air, has been considered the most practical way...

New AI noise-canceling headphone technology lets wearers pick which sounds they hear

Most anyone who's used noise-canceling headphones knows that hearing the right noise at the right time can be vital. Someone might want to erase car horns when working indoors, but not when walking along busy streets. Yet people can't choose what sounds their headphones cancel.

Those flat surfaces to either side may have other uses…

Probably not at the time.

Now it would definitely be on the list.
