Interenting topic. How the hell do you build electronics that survives 15000G
!
Got any technical info on RF proximity fuses ? I read somewhere that they
used the capacitance between shell nozecone and target to pull the osc off
frequency, a bit like a Theramin.
BTW, the Germans developed a remotely controlled TV guided bomb during WW2.
Luckily for the allies the picture broke up as the bomb approached its target
and
development was stopped.

Nope they were picking up early 'I love Lucy' shows by mistake.
Anyhow I thought the V2 was the last ditch bomb of the war.

Nope. This winged, rocket-propelled, and tv-guided bomb sank an Italian
battleship late in the war. The British called it the 'Chase me Charlie'
bomb. It was pretty effective when used by a trained crew. It was guided
from the launching aircraft by an operator with a
joystick.

Jeff

The TV-guided glidebombs of World War 2 were too far ahead of their time -
lens technology just was not able keep up. As the bombs reached their
target, there was no way to effectively zoom the image for finer guidance
during the most critical part of the run. Things went out of focus, and
the image turned into mush. So much for guidance. They never did work
well, and only a few really hit their targets effectively (one being the
example given).
The German glide bomb sets were better than the US sets. The US sets
(SCR-549 and SCR-550, ARE/ATE, AN/AXT-series) suffered from extereme
microphonics (virbrations that direct effect the performance of tubes),
and were quite useless in aircraft.
If anyone needs original 1944 AN/AXT-2 Operators Manuals, please contact
me off list.
There were many interesting developements in World War 2, mostly from the
Germans and the US, that really were bleeding edge (mostly secret). Some
of it is quite legendary - the so called "Wizard War" of radar
countermeasures, jet engines, the code breaking - but much of it really
has not been researched much (either because so much of the original
records are lost or recently declassified). Examples of the latter
are heat-seeking missles (US and German), digital encryption (SIGSALY),
passive search radar (Klein-Heidlburg), variously-controlled glide bombs,
magnetic anomaly detection, and so on.

Several 'last ditch' things were attempted. Schmetterling (Butterfly) was a
radar guided SAM that fortunately never saw service. The Henschel HS893
glide bomb did, and was used in active service in the anti ship role. The
original version was first radio, then wire guided, with the operator
eyeballing the track from the launch aircraft. The switch to wire was made
after the Brits found it's R/C frequencies and jammed them. IIRC it was used
to sink at least one warship. The TV guided version never saw service, but
they did make it work, though not perfectly, and it inspired the Walleye
glide bomb and Maverick ASM amongst others. To fit a vaccuum tube tv camera
and transmitter into a small enough package using WW2 tech was a feat of
electronics never before attempted.

This is new to me. Lets not forget the almost technology -- "The skip
bomber"?.
The idea was you would fly into space,then bounce of the Earth's
atmosphere
once, drop your bomb on New York and bounce again and keep bouncing
until
you land in Japan. The real details could be different but you get the
idea.

The Japanese developed a remote guided bomb as well, but apparently it was
easily "jammed" by turning on en electric shaver.
Just a story I read from an old '50's book on guided missles and rockets.

It was true, we had examples like that in our training manuals in the AF for
missile school, to show inovations and how the present day missiles have
moved up (back in 76) - even though we still had AIM-4F Falcons that were
about the biggest hunk of crap - tubes that were non-functional in certain
climates, cracks in glass envelopes, etc.
