I am a bit curious about how the US might have used this weapon. The PoD here is in early 1943 when a Allied spy provides construction plans and detailed engineering data for the V1. The decision to build the weapon is made NLT April 1943 & design/production schedules occur as in OTL, except some 14 months earlier.
With 1,000 of the new JB-2 available to ship out of the US between March & May 1944, & approx 4,000 more to be produced through June 1945, what would the best use for these? Training & preparation for use may within reason occur concurrent to set up & early production. So, combat use may occur after April 1944.
With the limited range of 240 kilometers it is not practical to bomb the Ruhr from UK launch sites. What are the other options?
