OT: Drawings of the 1942 German V2 Rocket

[Uwe Hercksen]

Yes, it seems that way. But a lot of resources was put into these war advances. The V2 project was actually bigger than the Manhatten project (Atomic bomb). A bomb is just a bomb (he he), the V2 was radio beam controlled, had all sorts of control mechanisms including analog computers and doppler system for cut of control.

Hello,

no, the Manhattan project was much bigger and it was not only a bomb.

They developed both a uranium and a plutonium bomb. But before they had
to develop methods to enrich the needed uranium isotop to weapon grade.
They had to design and build and operate nuclear reactors for plutonium
production. They needed a facility to get pure plutonium out of the used
fuel rods under very heavy nuclear radiation. The had to test the
critical masses of plutonium and uranium. They had to design the
concentric implosion to start the plutonium fission. But they had less
years than the V2 project. When they were ready, the war with Germany
was over.

Aha! Seems everyone finds that out early in their career. I carried a
full set of four colors with even back in the late 80's, even on
international flights. For that same reason.

The other problem back then were projectors. "So here is the block
diagram of the circuitry we want to talk about in this design review"
.... *POOF* ... clatter ... phut ... darkness came over the land. "Do you
have a spare bulb and some tools?" ... "Uhm, I think so, possibly,
maybe, let me ask".

That was usually true at IBM as well, at least after the department
secretaries stopped keeping supply cupboards (about 1994).

I actually took two semisters of engineering drawing, which nobody much liked

but was really valuable. Lots of kids nowadays know how to drive Autocad but not

how to draw. I still design with pencil on vellum.

You're not seriously suggesting that drawing that way was advantageous I hope. We can draw a whole ship inside and out now and show it in virtual reality - much better and faster.

Pencil drawing is advantageous for me, designing schematics and mechanical
stuff. I hand it off to people who do the electronic and machanical CAD entry
and go on to lay out PC boards or machine stuff. I find CAD entry to be clumsy,
and it slows me down.

That's just lack of experience and/or using cheap/free tools that have
crappy GUI's... or the "semisters" >:-}

...Jim Thompson

I do it the same way. I plead guilty to lack of experience in
mechanical CAD and PCB software, because nobody has wanted to pay me to
do any of that when there are lots of other folks who (with guidance)
can do it at least as well as I would, and work cheaper.

I'm looking around for a good modelmaking shop, because I have a bunch
of prototyping jobs coming in, it looks like.

Clueless. There was a lot of US military in that area of Alaska
during W.W.II.

Within 200 miles of Russia? There's only part of one little (for
Alaska) peninsula within that range, Cape Prince of Wales.

Really? You might get a clue that is was initially deployed while
still in the developmental stage. Germany was out of time and
resources. For such a worthless weapon, the U.S. put quite a lot of
money and work into using it to advance the state of the art of
missile technology.

If all they'd had were conventional warheads, they probably wouldn't
have bothered.

The German V-weapons (V-1 and V-2) cost $3 billion (wartime dollars) and was more costly than the Manhattan Project that produced the atomic bomb ($1.9 billion)

Nonsense, that so-called A4 airframe was a planned component of the A4/A10 combination that was definitely long range.

The A9/A10 combination that they almost finished was the "Amerika Weapon". Was meant to be flown by a pilot, guided by radio beacons. Had a 1 ton payload and 5000km range.

"The V2 was intercontinental, they could have thrown it into a trajectoryto hit

North America if they wanted, according to Aberdeen."



about a 200 mile missile.

An 80 km altitude is more than enough for intercontinental range and the A4airframe was the basis for earlier missiles that /were/ intercontinental. So the assertion that the V2 had intercontinental capability is true, just a little more invention was needed.

It took 30 tons of potatoes to make the alcohol to launch one V2, while the rest

of the country was starving. About 10 times more slave-labor workers died making

the things as enemy population died.

That slave labor statistic is dumb, the Nazis murdered those people, it's not like they were killed because of some kind of extraordinarily risky method required to build the V2.

It was a civilian terror weapon, and the

Brits had already shown that they would carry on.

The Nazis viewed it as a retaliation weapon in response to British bombing of German civilians.

It took nukes, the "Jewish Science" that the Nazis rejected, and inertial

guidance computers to make ICBMs into serious weapons. Using a gyro-guided

sub-orbital missile to deliver conventional explosives doesn't make sense.

Yep, and another 20 years... The Germans did not reject "jewish science," they put nuclear weapon development on the back burner because they reasoned it would not be ready in time to affect the outcome of the war.

Hindsight is 20/20 BUT it was within their means to develop lethal surface-to-air missile technology using more conventional search and track radars in combination with simplified target illumination directors enabling simpleterminal homing guidance for the missiles with relatively small conventional explosive fragmentation warheads. They could have wiped out the combinedBritish and American air forces if they tried to bomb the continent. Bombers back then had mountainous radar cross-sections, were slow moving, and struggled to operate at altitude. SAMs would have brought the war to a standstill, that is if you believe air power played a significant role in winningthe war, which it most certainly did.

 

[[email protected]]

Wiki says more like 1200 km altitude.



http://en.wikipedia.org/wiki/ICBM#Flight_phases



Depends on which continents you pick, I suppose.

Guess you lack the wherewithal to figure out if that number is dictated by physics or tactical operational necessity...

 

[Phil Hobbs]

There were a lot of ships hauling supplies to the US Army, US Navy
and to supply the Lend-Lease program. If the Germans had made it to the
Bearing Straits, it would have been easy enough to attack the military
installations, or use those crude missiles to attack the troop's morale.


A lot of supplies were flown across the Bearing Straits by Russian
pilots, in American built planes.

You're seriously proposing that anyone could have hit a ship with a V2?
Or even an _airplane_? And what military installations were there
within 200 miles of continental Russia?

You're making that up.

The Japanese occupied the Aleutians, and apparently were shipped a few V2s, so a

V2 attack on American soil could have happened. They might have stirred up a bit

of ice on the ground.

The Japanese were evicted by mid-1943, long before V2s were available, it was one of the earliest campaigns in the war.

 

[Tom Del Rosso]

The V2 is the only known weapon system that killed more of its makers
than its target. It helped end the war by draining huge amounts of
German resources for little damage inflicted on the enemy.

Like the Big Bertha gun that took a crew of 25 or 30 who could have better
served in regular artillery units.

Depends which ones you mean. IIRC the real Big Bertha was an excellent
weapon: a railway gun reduced the Belgian frontier forts in a few days.
Later on there was the Pariskanone, called Big Bertha by the press,
which was a complete waste of effort.

Nobody on the planet had the resources to do that in the 1940's,

especially the Germans, who had primitive radar technology. And the

defense would be simple: chaff and jammers.

As usual you're making stuff up to try to get out of making an ass of yourself. The Germans invented radar! Germany had the first operational radar inrecorded history, a shipping collision avoidance radar, in the 19th century! They were ahead of the GB and US in radar controlled AA guns.

Big Bertha was a world war I gun. Maybe you are thinking of the Gustav gun. That was very effective during a couple of WW2 battles

Indeed. And the only reason they were not effective during the air-raid on Germany was that the AA guns did not have height setting of the shells, so even though the AA guns were radar guided, they did not send the shell to the correct height

It was more than that, the Allies knew enough to constantly change their altitude during flight to evade flak.
