F-15 vs Su-30MKI

Published on June 4, 2012,

Useful F-15 AN/APG-70 radar mode is the velocity search. When this is selected the radar shows only target velocities at long range, so if the pilot sees a return that is bowling along at Mach 3 and 70,000ft (20,000m) with no identification friend or foe (IFF), he can be fairly certain that he is dealing with a MiG-31 or MiG-25.

The radar can also be used to scan the field of view displayed in the HUD for up to 10 miles (16km) ahead of the F-15; in this mode it automatically locks on to the nearest target, which is then interrogated. If an IFF response shows it to be friendly, radar lock is broken and the radar continues to search for the next priority target.

The concept of the F-15 Eagle as an air-superiority fighter was first proven in the summer of 1982, when the Israeli Air Force, which was then rearming with the American aircraft, embarked on a period of intensive action in support of the invasion of southern Lebanon. Israeli and Syrian combat aircraft had been involved in a series of skirmishes over Lebanese territory since 1979, and in the course of these F-15s encountered MiG-25s for the first time.

Since the F-15 had been brought into service to counter the MiG-25 in the first place, the results of these actions, which were firmly in the F-15′s favour, attracted a lot of attention. The Israelis reported that the Foxbat was fast at high altitude but that its manoeuvrability was poor, as was the visibility from the cockpit. At medium and low altitudes the heavy MiG-25′s speed fell away markedly and its handling qualities were sluggish.

During the Gulf War, F-15s claimed no fewer than thirty of the thirty-nine Iraqi aircraft destroyed in air combat. In every case the Iraqi pilots failed completely to get the best out of their aircraft, even though some were MiG-29s, which in theory were a match for the F-15.
