These first exercises ran at Korat Royal Thai Air Force Base and showed the advantages of the smaller and more technologically-advanced Gripen over the Russian Sukhoi. Several of Li’s summations from the exercise are:
The JAS-39 performance was at its worst inside the within visual range (WVR) envelope. Over a two-day period, PLAAF pilots shot down 25 Gripens at a loss of only one Su-27. The Su-27 has an advantage over the performance of the JAS-39 due to its more powerful Salyut AL-31F engines, and the Swedish aircraft was handicapped in that it was equipped with the older-generation AIM-9L Sidewinder instead of the current-generation Diehl IRIS-T missile.
Once the exercise transitioned to beyond visual range (BVR) combat, the superiority of the JAS-39 became readily apparent. The Swedish aircraft shot down 41 Su-27s over a period of four days with a loss of only nine JAS-39s.
The Su-27s flown by the PLAAF were operating with a modified version of the NIIP N001 radar that could fire the Vympel RVV-AE active-homing air-to-air missile (AAM). But its effective detection range was only 120km in comparison with the JAS-39’s Ericsson PS-05/A at 160km. The Gripen’s Raytheon AIM-120 AAM also outranged the RVV-AE at 80km versus only 50 km for the Russian missile.
Li stated that the JAS-39C/D’s much smaller radar cross-section (RCS) at 1.5-2.0 m2 was a major factor, as the much larger Su-27 is easier to detect at 12 sq miles. The JAS-39 can also ripple-fire up to four AIM-120s simultaneously but the Su-27 can fire only one RVV-AE at a time.
Gripen achieved 88 percent of its kills at 19 miles or greater, while the Su-27 had just 14 percent of its kills at this range. The RTAF also had 10 kills at a distance of more than 31 miles compared with zero long-distance kills by the Su-27.
