FAN SONG

The maximum radar range of the E-band Fan Song A/B/F radar varies between 60-120 km depending upon target type, altitude and operating conditions. The G-band Fan Song D/E maximum range is extended to between 75-145 km under equivalent conditions.

As U-2 operations continued in the late 1950s, photography from these missions revealed that more and more Soviet Air Force and Air Defense units were receiving new combat and electronic equipment. For example, P-30 (probably the Fan Song series) radar systems that could detect aircraft at altitudes above 20 kilometers (about 66,000 feet) began to enter service with Air Defense units during this period. In addition, Soviet air regiments in 1959 received T-3 (probably SU-9 fishpot) high-altitude interceptor aircraft with a supersonic speed and an altitude ceiling also above 20 kilometers. And SAM units around that time started receiving the highly regarded S-75--almost certainly the SA-2 Guideline missile system, which had a 25-kilometer (approximately 82,000 feet) engagement altitude against targets flying at up to 1,500 kilometers (about 930 miles) per hour.
