In the above video, The Sukhoi SU-35 made a stunning performance at the Paris Air Show 2013.

The Sukhoi Su-35 Flanker-E is a Russian 4 ++ generation fighter. Sukhoi Su-35  is a single-seat, twin-engine, highly maneuverable aircraft. It is an improved derivative of SU-27 FIGHTER JET.

SU-35  has 2 powerful AL-41F1S engines manufactured by Saturn Lyulka, with TVC (vector nozzles) in 3D (up-down, right-left) for maximum maneuverability if needed, also has FADEC technology (Full Authority Digital Engine Controls)


The Su-35S has 3 powerful and advanced radars.

An  ESA (hybrid between PESA and AESA) X-band radar called N035 Irbis-E, is currently the most powerful radar in the world, with a range of 400km for an aircraft with RCS 3m ^ 2 located on the nose of the fighter, this radar can detect a cruise missile and tactical UAVs of low radar signature (RCS of 0.01m ^ 2) at 90 km.

The Su-35S also has two AESA L-band radars in the wing extensions, the N035L, these AESA radars have as their main function, detect Stealth aircraft (LO and VLO), in addition to acting as EW (jamming) for the enemy communications and as long-range IFF and many other functions, all this at great distances, in addition to being able to geolocate them


The Su-35S has an advanced IRST system, the OLS-35 this OLS consists of IRST, laser rangefinder, and TV camera, 3 in 1, can detect up to 90km (back of the target) and up to 50km (front of the target ), and follow up to 4 targets simultaneously.


The cockpit is given by two large color screens with BACKUP, it has an open and modular architecture, it also lacks analog indicators since it is 100% digital.


The Su-35S, like the other 4 ++ generation aircraft, has several passive and active fifth-generation sensors distributed throughout the plane, in order to collect information from their environment such as ELINT, advanced RWR, MAWS, etc. The KNIRTI SAP-518 Khibiny-M system is the new ECM / EW pod that equips for the self-protection of the fighter or the KNIRTI SAP-14 that acts as a noise jammer similar to the AN / ALQ-99E that equip the EA-18G.


The Su-35S is very agile even if it did not have any TVC, this is due to the fact that the “airframe” (fuselage) has been reinforced, as well as the use of composite materials for non-structural elements, such as the dome, wheel the nose, the door, and the flaps. Some of the structures of the fuselage are carbon fiber and lithium-aluminum alloy. On the other hand, the extreme maneuverability of the Flanker is due to the integrated control system, where all the moving parts are synchronized.


RCS OF Su-35:

The Su-35S, unlike the previous Flankers, has a low radio signature, so it is classified as LO (Low Observability), where its RCS is close to 2m ^ 2 (it can vary) in “clean” configuration, this it is due to an increase of composite materials, streamlined and refined aerodynamic design and the use of RAM (Radar Absorbent Material) paints, when carrying armaments, the RCS of the Su-35S increases, but not significantly because of the missiles and pumps, they are also placed RAM paint.


The Su-35S can carry a large number of weapons, as well as a wide variety of weapons such as air-to-air/air-to-ground missiles, guided bombs, and unguided bombs on 12-14 pylons


The Su-35S, from its conception, has a great internal capacity of fuel, including protection against explosions, which is why practically never has been seen with external tanks, unlike Western aircraft that we often see them with tanks in pairs, and that in turn is a disadvantage for two reasons:

a) It removes space for more armament, and

b) Because it limits the maneuverability of the fighter and increases the drag (resistance) to a great extent, where it generates greater consumption and power in the engines (even though these can be launched before combat )

This does not mean that the Su-35S can not carry external fuel tanks, in fact, if it can, as well as become a “tanker” if necessary.
