(b/w 19k) from Ever Changing Page of Roy Cochrun. John Geiger collection

Single-seat all-weather interceptor. The two jet engines were installed in tandem, behind the deep intake in the nose. The forward engine exhausted under the fuselage, the aft engine at the extreme tail. The cockpit was offset to left to make room for the air of the aft engine.

The radar was put on the upper lip of the nose intake. The Su-15 prototype crashed because of flutter during the test flight.

Development was abandoned, designation was used for another P.O.Sukhoj Su-15 known to the West as 'Flagon'.
