High Fix**

This is an aircraft range-only intercept radar in fighter-type aircraft. There is very little unclassified information available about this system.

The radar is in service in declining numbers.

Platforms include Su-7/17/20/22 Fitter aircraft; the radar was also fitted to MiG-19P Farmer B aircraft (which is no longer in service) and on early versions of the MiG-21F-13 Fishbed .
