السو 35 هي تطوير للسو27 ..
Before there was theory of 2 different SU-35s. One was a mid-life modernized SU-27 Flanker, but there’s also a much more re-engineered “SU-35” variant with canards, thrust vectoring, etc. which has been confused with (and possibly redesignated between) the SU-37.
Revelations after 2007 began to provide answers. This article explains the sources of the widespread confusion regarding the SU-35’s layout and key characteristics, reviews what is now known about the platform, and tracks its development. Those developments are likely to have broad consequences. The aircraft has a home customer in the Russian Air Force, and the SU-35 is being positioned to succeed most SU-30MK variants as Russia’s fighter export of choice within the coming decade.

The SU-35S will also depend on its sensors. It couples an electronically-scanned array with a 2-step electro-hydraulic drive unit , which creates a maximum radar beam deflection angle of 120 degrees. The NIIP Tikhomirov Irbis-E passive phased-array radar radar can reportedly detect and tracks up to 30 air targets, simultaneously engaging up to 8. It can also reportedly detect, choose and track up to 4 ground targets and engage 2. Detection ranges of over 400 km/ 240 miles hav been reported for airborne targets, which are the easiest, but resolutions are unspecified. Detecting a 747 opassenger jet at 400 km is much easier than detecting a JAS-39 Gripen lightweight fighter, and information about its resolution would be needed before its real capabilities would be clear.

Full stealth jets like the F-22A Raptor, of course, create drastic reductions in radar detection range that make them a special case. In an emerging age of stealth fighters, the 80km+ detection range of the SU-35S’ IRST (infra-red search and track) system is very significant.
