Airport air defense should introduce a set of radar-based air defense systems (such as the British Sky Sabre), a set of infrared-based air defense systems (such as the German IRST-SLM), replace manually operated command line air defense with the Pantsir S1, and replace short-range infrared air defense with infrared and imaging-based 81 short-range systems, in order to cope with the pressure from anti-radiation missiles.
The firing range is limited as follows: radar-based separated air defense can only be launched within 20 km; infrared-separated air defense can only be launched within 16 km; the Armored S1 manually operated air defense can only be launched within 12 km; infrared and image-separated 81 short-range air defense can only be launched within 8 km.
