Closest airbase I can think of with the facilities to support F-16s is Toledo Express, which IRL hosts a squadron for the Ohio Air National Guard.
Yep. Toledo Express is within the potential launch zone.
Also, include Selfridge Air National Guard base outside of Detroit
Edit: Bad news for us - every single runway at Detroit Metropolitan Airport exceeds minimum requirements rather handily - if I was a betting man, I'd bet you Victorian operations would center out of there.
Other metropolitan airports that exceed the minimum requirements within the area specified in the above map include -
- Bishop International Airport (Flint Michigan) - 2x Runways of 7000+ length
- MBS International Airport (Freeland Michigan) - 2x Runways, 1x of 8000+ length and 1x of 6000+ length
- Cherry Capital Airport (Traverse City Michigan) - 2x Runways, 1x of 7000+ length and 1x of 5000+ length
- Mansfield Lahm Regional Airport (Mansfield Ohio) - 2x Runways, 1x 9000+ length and 1x of 6000+ length
Note, this list is by no means comprehensive, but it does mean that the Victorians have at least 5x Civilian Airports that they could potentially repurpose for F-16 base sites within the ideal distance. I can't get much more comprehensive, but we should try to ascertain the status of all of these installations. I doubt time has necessarily been kind to them, but they could all still be capable of maintaining and fielding aircraft.
