X-7 Rotkäppchen anti-tank missile

A piece of technology I did not know was in use as early as it was.  Of course, now I want to put a few of these on my Weird WW2 German Vehicles.  Here is a great mockup of a turret mounted launcher on an E-100 Maus

The Panzerabwehrrakete X-7 "Rotkäppchen" (Red Riding Hood) was a anti-tank missile. Designed and developed by Ruhrstahl AG in 1943. 

The X-7 was shell shaped body had two wings at its aft end with parabolic leading and trailing edges and two small pods for the wire link spools were attached to the wing tips. The wire link control system was employed for the X-7 Rotkäppchen which used Düsseldorf FuG 510 transmitter and the Detmold FuG 238 receiver, also a radio controlled system was planned for the X-7 Rotkäppchen using the FuG 203/230h. Detonation was achieved by use of an impact fuse.

 trials were undertaken on September 21st 1944 with seven X-7 missiles. Because of the unusual and unfamiliar flying characteristics the first four weapons had ground contact after some distance and therefore crashed. On the next two the rocket engine exploded on the way to the target. The last Rotkäppchen flew all the way and hit the target tank at a range of 500m dead center.

Only about 300 X-7 Rotkäppchen were completed; mass production was planned and had already started at the companies Ruhrstahlwerke in Brackwede and the Mechanische Werke in Neubrandenburg. Many almost finished weapons were captured by the allies (which the French continued to develop after the war).  There were unconfirmed reports of the X-7 being used operationally on the eastern front, and it appears that this missile was extremely effective even against the heavy armoured Stalin tanks.

Brian has already made up some rules for a Stug variant with an X-7 launcher at his great Weird WW2 Blog here.  Great minds think alike I guess!

You can certainly see older, small chassis getting a new lease of life with this small launcher fitted.

"1946 Racket AT Misile tank" Late WW2/'46 German AT Guided Missile vehicle. Based on a Panzerjager IV chassis and using the X-7 Rotkappchen Missile.  From http://www.modelblokez.org.au/othermodels.html#prettyPhoto

And here is the Pz.IV Raketenwerfer: Missile tank on Panzer IV chassis, armed with four wire-guided Х-7 Rottkapptchen AT missiles".   A single prototype was made.

From Achtung Panzer: "It was also planned to arm Panzerkampfwagen IV Ausf C/D/E with four 280mm or 300mm rocket projectors mounted in a special turret, which replaced the standard one. Turret consisted of forward mounted cabin with machine gun and rear mounted hydraulically operated launching frame. A single prototype was produced and tested although full-scale production did not take place. It was designated as Raketenwerfer auf Fahrgestell PzKpfw IV."

  1. That's the good part about blogs, is to learn something every day. Thanks for sharing!

  2. Hm, not used to seeing kilogram as a unit of thrust.

  3. Never saw one of those before looks great! Lovely job,

  4. Don't forget that they designed a carriage-mounted version to deploy via infantry similar to that of the PaK guns. Got rules written up for a man-portable X-7 but its more like the Soviets early Sagger ATGM set ups. Just imagine dug in teams of X-7s deployed during a massive Soviet tank attack! Now that's some Weird WWII gaming!!!!

    Thanks for the nod, buddy,

    1. Yes indeed it would be! In my mind I see PaK guns being replaced with smaller Recoilless Rifles. There were a few in service, and I think that this would be a natural avenue for greater development. Backed up with a brace of semi-man portable X7 launchers for the big IS style tanks this would make formable defensive capabilities
