An early 1970’s Lockheed concept for a fully reusable shuttle. Shown here is the orbiter, a minimum-mass, low-cross-range design with a vast fuselage and relatively tiny wings. The system used a reusable flyback booster for the first stage. Far more information is available on this and related concepts in Aerospace Projects Review issue V3N2 and V3N2 Addendum, available HERE.
That looks a lot like Tacit Blue.
