Canard Rotor Wing was a Boeing-DARPA effort to design a vertical takeoff system with enhanced cruise range. jet exhaust would both drive the rotor's tip jets for vertical takeoff and provide thrust for level flight with the rotor halting to function as a wing.

though defined by its helicopter competitors such as the AH-56 and S-66, the 1960s' AAFSS program did permit convertiplanes and tiltwings. the Boeing Vertol Model 147 made use of such a configuration, deriving the lift system from the VZ-2.

Rockwell International next-generation bomber studies from the 1970s. at the time, the advantages of stealth were not realized in full and attention was given to concepts such as active protection and hydrogen fuel alongside the more conservative supersonic penetration option.

photographs of Sukhoi's T8, the prototype designation for the Su-25. as part of the LSSh program, several of these test models would be built in the 1970s. the first photo is of an earlier mockup possessing a distinctive nose and intake shape.

Virtus was a mid 1970s NASA proposal for a Space Shuttle Orbiter transport vehicle. incorporating two B-52 fuselages into its design, it would have been able to perform transport flights for both the Orbiter and outsize rocket components.

from the 1970s onward, Boeing would conduct several studies for a supercruise-capable fighter. these heavyweight interceptor proposals would begin to incorporate certain stealth elements as time progressed, bleeding into Boeing's pre-ATF developments.

McDonnell Douglas studies for ATT, a reduced-observability STOVL transport program. closely-related is a jet-propelled design proposal of slightly greater weight class.
