Boomerang grenades would be a classic mis-direction project. The enemy gets ahold of the idea, starts working on it and deploys the weapon to its troops who are soon clobbered by self-fire.
Watching The History Channel today. (Hence, accuracy is suspect.) They claimed the Russians had plans for a flying submarine (or submersible airplane) in WWII. It was never built.
However, they did build one flying tank. Basically, wings and an empannage werre attached to a tank and it was towed aloft by a bomber. Upon reaching the landing zone it was to jettison the flying structure upon landing, after which it would be a regular tank. It was flown once.
The Panjandrum was a huge self-propelled demolition bomb - it had a pair of enormous wheels propelled by rim-mounted rockets firing tangentially. It featured in a Dad’s Army episode and caused about as much havoc as it would if it had ever been deployed operationally.
Blohm und Voss came up with some other asymmetrical designs as well as the Bv141. I found this out only a few months ago. There are some pics on the web.
This is one of those contraptions I mentioned above that was supposed to demolish the Atlantic Wall. It wasn’t the only one. I think they would’ve done as much damage to our side as theirs, if they’d actualy deployed it.
Yes. “Here’s the new wonder device, which will roll unerringly to its destination as long as the ground is perfectly level, all the rockets fire with perfect synchronisation, and the device itself, which is roughly the size of a double-decker 'bus, is not damaged. Any questions?” :smack:
We tried that in the Thirties, which is why we found ourselves in France in 1939 with a whole bundle of obsolete stuff and got our sorry behinds booted the following May.
