I mean, the V1 was a 1944 weapon and is a bit advanced.
That said, things like the Kettering Bug existed as early as WW1, so there is nothing inherently wrong with cruise weapons. Which means the controversy here is centered on the propulsion type, or the pulse jet engine.
So all things said, Yylledenwhatever already has very primitive mid/late 1930's level jets which means strapping one of the engines to a bomb can't be that hard.
So given the V-1's flaws were... Numerous... I don't really see an issue with it, given the highly limited utility.
It is up to Volyus, of course, just my two cents on the matter.
