“Should NATO be afraid of Russia’s Su-27 and Su-30 fighter jets?” the magazine said. “Calls for special attention to be paid to Russia’s old-fashioned tactical aircraft. Military officials say it was a mistake to believe the Russian Air Force posed a danger to U.S. pilots, largely because of the new Russian multi-role Su-35S fighter jet. According to the London-based International Institute for Strategic Studies, the number of Su-35s is small, and NATO estimates that Russia now has 90 Su-35s and 220 Su-27s.
The more than 200 Su-27s are obsolete aircraft that were put into mass production in 1985 and do not have long-range guidance and data chains. But in close combat, however, they also pose a very serious threat to the pilots of America’s most powerful F-15 and F-16 fighter jets due to their unique manoeuvrability.
These Su-27s have very serious defects that prevent these aircraft, which are basic modifications to the production line, from seriously threatening the Ace of the U.S. Air Force. First, a very weak old-fashioned radar, equipped with a Cassegren antenna, rotates automatically when scanning the space in front of the aircraft. The maximum on-face detection range is not more than 80-100 km and the maximum detection range for tail-end mode is not more than 30-40 km.
