From wiki ''The F-15 in all air forces had an air-to-air combined record of 104 kills to 0 losses in air combat as of February 2008.[43] To date, no air superiority versions of the F-15 (A/B/C/D models) have ever been shot down by enemy forces. Over half of F-15 kills were achieved by Israeli Air Force pilots.''
Mind you this also from wiki''An earlier variant of the Sukhoi Su-30MKI, the MK, took part in war games with the United States Air Force (USAF) during Cope-India 04, where USAF F-15 Eagles were pitted against Indian Air Force (IAF) Su-30MKs, Mirage 2000s, MiG-29s and elderly MiG-21. The results have been widely publicized, with the Indians winning "90% of the mock combat missions".[42]''
