"U.S.A.F. Intercepters
A years ago the U.S. Air Force abandoned
plans for a long-range intercepter
after bids had been called for a number of
designs. It is now reported that design
proposals for a medium-range intercepter
are being considered. Studies are believed
to have been submitted by Convair, Lockheed,

My dear Nugo,

to this moment,the only known project for this tender is the F-106 Interceptor,which was
a version of Delta Dart with canard and box intakes,and may be that model was it.
