Allied bombings had little to do with delays in getting V-1s
operational, so presuming an early debut of them is unrealistic. (same
thing with jets, buggy and immature technology combined with limits in
the industrial base kept them delayed) Then, the things were terribly
inaccurate. At their extreme range, hitting greater New York, even less
Manhattan, would have been iffy. Any attack would have been a dramatic
propaganda blow, but serve no useful military purpose. And finally, you
would not need a carrier to launch them. Any moderate size ship could be
fitted with simple fold out launch rails, they would only need to extend
about 15 ft away from the hull and only need to handle a couple of tons,
a simple installation. But by '43/'44, the Atlantic was an Allied lake
and any German surface types wouldn't have a chance. I love "what if"
scenarios, but let's keep a little realism to it.
