The Foxbat was one of the most feared and enigmatic aircraft of the Cold War. We chat to Mike Guardia, author of the new book Foxbat Tales: The MiG-25 in Combat about the aircraft’s innovative radar.

The MiG-25 (NATO reporting name Foxbat) combat aircraft first graced the skies in March 1964, entering service with the Soviet Air Force in 1970. Reaching top speeds of almost Mach Three (1,600 knots/3,000 kilometres-per-hour), the MiG-25 was a potent interceptor and reconnaissance aircraft.

For the Foxbat, speed was life. It had little in the way of self-protection, but it did have a mysterious radar under the nose. The Smerch series transmitted on an X-band frequency of 9.993 gigahertz/GHz, but had a secret dual band capability allowing the radar to also transmit on a Ku-band frequency of 14.9GHz.

In our latest Armada EW Podcast Mr. Guardia reveals what made the Smerch radar special, and how the West unravelled its secrets.
