A 1968 letter from Defense Secretary Clifford to State Secretary Rusk
at http://www.state.gov/r/pa/ho/frus/jo...b/xii/2262.htm mentioned
that the air bases in Spain were originally built for SAC operations
and some B-58 bombers and accompanying tankers were earmarked for
forward deployment there.


The B-58 was a high-maintenance airplane and very rarely moved for very
long from home base.

Moving a squadron for an extended stay would be a logistical
challenge-- just the number of tools, spares, and test gear was not
something done on a whim. I suspect there were no cargo aircraft
assigned for such a move, so it's not something that could be set in
motion in under a week or so.

During the Cuban Crisis some B-47's were flown to various disparate
civilian airports within the US, but those required much less ground
support.
