U-234 and Me262

I've been following the thread on the U-234 and was most intetested in
the statement that there was a Me262 on board. Can anyone provide any
substantial evidence of this, other than the statement that there was
one on board? And if there was one on board what happened to it? I
would assume that if there was one aboard that it remained in Navy
hands. There doesn't appear to be any Navy records of it.

There was no complete Me-262, there were components for
one. The cargo was carried in multiple containers fitted in
place of the mines the type normally carried.

Given that the sllies captured hundreds of intact Me-262's
many in flyable condition I doubt much was done with these bits.

To be more exact there were 240 tons of German documents and war
materials aboard U-234. The war material included 560 kg of Uranium
Oxide, jet & rocket components for missiles and aircraft, the latest
proximity fuses and AP shells, a complete pressurized pilot's chamber,
and various other stocks of strategic materials along with components
to various guidance systems.
The boat also carried several Messerschmitt engineers with documents
on the latest jet aircraft... but no complete aircraft, just
components in storage containers.

To my knowledge the Germans never developed a true proximity
fise as they lacked the cavity magnetron and miniaturized electronics
necessary.IRC correctly the best they could manage was the "Kranich"
acoustic proximity fuze.

The boat also carried several Messerschmitt engineers with documents

For several read two, August Bringewalde, Willi Messerschmitt's "right-hand
man"
who was in charge of ME 262 production, and Franz Ruf, an industrial
machinery
specialist who designed machines and appliances to manufacture aircraft
components.

By the time the shipment had been readied, the German had in their
possession possibly several dozen "dud" Allied proximity fuses, recovered
from the battlefield. Gen Eisenhower had authorized the use of these devices
over land at the onset of the Ardennes Offensive. German authorities offered
soldiers a bounty for the recovery of partial or complete "duds". Their
analysis revealed the super-tough tubes employed therein.

However, no Allied proximity fuse developed duringWWII used the resonant
cavity magnetron. Research and development on the miniaturization of such
devices had not begun by the end of the conflict in Europe. Instead, a radio
signal on a lower frequency was used.

As best I've been able to learn, the characteristics of the cavitron were
better and more fully understood only long after the war, when it was
realized that these devices could be fabricated from a far lesser amount of
material (and from materials less dear than copper) than formerly had been
used.

A form of "smart" artillery shells was built, (at least in the US, during
the 1970's) using a rather tiny, shrunken cavitron in conjunction with some
form of "guidance fins" on the shell body. The cavitron allowed friendly
artillery to loft shells to the area of an enemy advance; other circuitry
connected to the return radio-wave receiver could discern between a target
of great mass (i.e., armor) and a target of lesser mass (i.e., a lorry) and
to "select" the more massive (and presumably more valuable) target, for
which the "fins" served for terminal steering.

Individual shells could either achieve a direct hit on the selected target,
or detonate overhead of it within sufficient proximity to disable a tank or
self-propelled artillery, for example.

Try all these:

Bad: Acoustic, Graf Zeppelin Institute
Elku/Paplitz: Electro-Acoustic, ELAK, Kiel
Fuchs: Radio, AEG, Berlin
Isegrimm: Electrmagnetic, Ernst Orlich Institute, Danzig
Kakadu: Radio, Donaulandische GmbH, Vienna (3000 produced for Hs 293)
Kranich: Acoustic, Ruhrstahl AG, Brackwede
Kugelblitz: Radio, Patebt Verwertungs Gesellschaft, Salzburg
Kuhglocke: Electrostatic, Rheinmetall-Borsig
Lotte: IR
Marabu: Radio, Siemens-Halske
Marder: Radio, Ernst Orlich Institute, Danzig
Meise: Acoustic, Neumann & Borm, Berlin
Pinscher: Radio, Ernst Orlich Institute, Danzig
Pistole: Photo-Electric
Roulette: IR, Brinckmann, Gera
Stimmgabel: Acoustic, Graf Zeppelin Institute
Trichter: Radio, Blaupunkt
Wassermaus: Photo-Electric
Wiesel: Radio, Ernst Orlich Institute, Danzig
Zunder-19: Aerial bomb prox. fuse for burst height of 25-30 ft above
ground, Rheinmetall-Borsig

At least some of these were on U-234...

The boat also carried several Messerschmitt engineers with documents

For several read two, August Bringewalde, Willi Messerschmitt's "right-hand

What about Dr. Schauerns and Dr. von Chiligensberg also?

Upon further reading on U-234 I discovered that the proximity fuses
onboard were of the IR type.

Err.. my memory is the two were quite separate. ISTM the proximity
fuses were in the 150 mhz range, NOT microwave at all.

Yes I've already been corrected in that regard, thanks anyway.
