I have read about a pair of Mustangs that supposedly overflew a V-2

where an Allied aircraft managed to either damage V-2s on the ground
or see them in flight?  I'd like to know details if possible.

v/r Gordon

A V2 accelerated at nearly 1.1G  (10m/s/s) at launch and reached a
peak of over 6.2G some 70 seconds later.
Thats an initial acceleration of about 40kmh or 24mph faster every
second in the first second.

After 10 seconds the missile will be travelling vertically at around
250mph, all this while tilting over.

The chances of  'catching' the launch of the missile from its well
disguised lanched sites (non of which were ever detected) and then
applying the correct gun deflection are next to nill.

I would suggest that if a hit was obtained the 10 tons of liquid
oxygen, ethanol fuel and high explosives on board the V2 would
detonate and that it would then be more appropriate to score the
allied fighter pilot and his wingman as the first aerial kills by a
guided missile.

Does a V-2 qualify as a "guided" missile?- Hide quoted text -

Certainly the V2 was guided: either with a simple inertial system (one
PIGA accelerometer to shut down the engine when the desired velocity
was released) or in 25% of cases the Hawaii Viktoria "leiststrahl"
guidence beam, possibly with the use of doppler cutoff. This later
beam controlled lateral dispersion only as the tilt over angle was
still controlled by the gyroscopes. A Hawaii - Viktoria 4 using a
beam riding system based around a giant 7m wurzurg had been built and
tested.

The Wasserfall SAM, based in V2 technology but using storable
hypergolic propellants was to use two guidence systems:

1 either command guidence with a beacon tracking the missile, an
advanced radar tracking the target and commands passed up by a command
link automatically. There were various optical tracking systems as
fall backs in case of jamming of the radar and to get a system working
quickly. Surving sketches usually show a 7m Manheim-Reise radar being
used. Maheim was capable of considerable accuracy, auto tracking and
selecting an individual target in a formation. My understanding is
that it was to be based in 13.5cm Magnetron technology though 54cm and
27cm triode technology was available as well. The radar is in anycase
likely to have been the 10cm wavelenth on a 4.5m dish Egerland
Marbourg system then being tested.

2 or a beam riding system with the beam formed in the same radar dish
as the tracking radar.

I believe minutes show that the beam riding system was chosen as due
to the use of directionally sensitive antena it would have been
extremely difficult to jam. In fact this is the cases with all the
uplinks, its the down link that is vulnerable.

The Kehl-Strassbourg FuG 203/ FuG230 kehl strassberg system that was
used on Fritz-X and Hs 293
was only experiemental or interim on the Wasserfall and any jamming
abillity against it limited.
It incidently had 2 different radical frequency changes designed to
delay jamming attempts that
were nerver released fromstores. (different antena required)


FuG 205/FuG 235 Greifwald/Kolber FM (frequency modulated) instead of
amplitude modulated system as drop in replacement backup for Kehl/
Strassberg in the event of significant jamming being detected.


FuG 510/FuG 540 Kogge/Brigge High Frequency 1200Mhz/25cm impulse
modulated using directional polyrod antenna was to be the core of a
number of German guided missiles with development starting in 1944.
It was designed to be very immune to jamming due to the type of
modulation
used. This sytem was to be the basis of several German missiles.
