SDK-5
Already used for a MiG-15, this designation was repeated for MiG-17s used for further tests of the guidance system of the KS-1 Komet cruise missile. The original test-bed for this system had been the M1G-9L, and like that aircraft the SDK-5 had forward-facing antennas on the nose and wings and an aft-facing antenna above the tail. Like the MiG-9L this aircraft later assisted development of the large supersonic Kh-20 (X-20) missile.
