...a predecessor of today’s guided cruise missiles...
I read somewhere that the V3 (planned but not built) was going to be radar guided by receiving radio waves for a direction. Then either by range or by intersecting radio wave of a different frequency, they would cut their engines. This would have resulted in a FAR more accurate “bomb”
Fast prop planes would put their wing under the buzz bomb’s wing and tip it over sending it out of control. Great sport!
The USN had a mini-biplane version in development during WWI.
Not to be outdone, the US Army hired Charles Kettering to design one for them, but the war ended the work on both.
