Stepping back to the B-29/B-50 for a jiff:
Stretch B-29, turboprops, swept aft stabilizers.   Enlarged RASCAL called, say for instance, the Rebellious Redneck or something as such, and for self defense 2 Phoenix and two Sidewinders.   In USN service circa 1980.     (or whenever pre-SALT-II was)   Presumptions:   The Superfortress was kept in service as an adjunct to USAF and USN bombers and was used for this type of mobile missile delivery system.   I guess that means a bunch of frugal Baby Boomers in positions of power so it truly would be a Whiff.  (Epic Facepalm emoticon inserted here).
