The KGW-1 'Loon' illustrated above is an American produced variant intended specifically for Naval use.
The US made 'JB2' copy (or the Loon variant, can't remember) of the V1 was, if I recall sent to Japan onboard a Carrier for launch from there with the war ending before it could be used, so in that respect the Technology headed to another 'East'.
