The core of the Su-35 armament is a new radar control system with a phased antenna array (Irbis-E). It features unique capabilities in terms of the target detection range. This is a development V V Tikhomirov Research Institute of Instrument Production. In design, this is an X-waveband multi-role radar with a passive phased antenna array (PAA) mounted on a two-step hydraulic drive unit (in azimuth and roll). The antenna device scans by an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60°. The two-step electro-hydraulic drive unit additionally turns the antenna by mechanic means to 60° in azimuth and 120° in roll. Thus, in using the electronic control and mechanical additional turn of the antenna, the maximum deflection angle of the beam grows to 120°. Irbis-E radar control system detects and tracks up to 30 air targets, retaining continuity of space observation and engaging up to eight targets. The system detects, chooses and tracks up to four ground targets in several map-making modes with various resolution at a range of up to 400 km, without stopping to monitor the airspace. Irbis-E radar detects air targets with an absolute cross section of 3 m2 on a head-on course at a range of up to 400 km. Being an improvement on radars with a PAA, Irbis has much better capabilities: expanded (by more than twice) operating frequency band, increased from 70о to 120о target detection and tracking zone in azimuth, substantially (by 2-2.5 times) increased effective range, improved anti-jamming capability, etc. In this aspect, Irbis is comparable to the best foreign counterparts, outperforming most of the US- and Wes-European-made radars with passive and active PAA. The Research Institute has been developing Irbis since 2004. By now, the engineering prototypes of the system have passed the required bench trials. The first of them has been installed on the Su-30MK2 flying laboratory and is undergoing flight tests. The first flight of the flying laboratory with Irbis onboard occurred in early 2007 at Gromov Flight Test Institute. During the flight, the laboratory proved the superior performance of the new radar in the air-to-surface operating mode. Among other new onboard systems of the Su-35 is modern navigation and radio communication equipment, systems maintaining fighters operation in a formation and a highly efficient electronic countermeasures suite. The component package of the latter and its complementation with specific jamming devices can be determined by the customer.

The Su-35 has long been a brand name in the aviation world. Since 1992, an export version of the Su-27 fighter (created under the order of the Russian Air Force) has been demonstrated at international air shows. At the turn of the millennium, Su-35 fighters participated in the tenders of Korean and Brazilian air forces. By the mid-decade of the new century, a general concept emerged of a considerably modified Su-27 fighter, which retained the name of Su-35. What is new in the Su-35? First off, the fighter will get an improved airframe, which will dramatically increase its service life to 6,000 hours, 30 years of operation (the time before the first test and recondition and the between-repairs period has been increased to 1,500 hours, or 10 years of operation). Aerodynamically it is similar to the Su-27. But unlike the Su-30MKI it will feature no canard fins. All the three channels will have electrically signaled control without mechanical cabling. The use of a new integrated control system (developed by MNPK Avionika Moscow-based Research and Production Association) simultaneously performing functions of several systems – remote control, automatic control, limiting signals system, air signals system, chassis wheels braking system – will enhance the fighter’s handling capability and maneuverability. Among the Su-35 design features, worth of note is the absence of an overhead brake flap, a standard characteristic of the Su-27. Its functions are performed by an active rudder. The Su-35 chassis has been reinforced because of the increased takeoff and landing weight of the aircraft. For the same reason, the front bearing has two wheels. The improved radar stealth reduces the reflectance of the Su-35 in the X radio waveband and in the angle range of ±60°. Another important difference of the Su-35 from predecessors from the Su-27 family is the use, in its power plant, of new engines with an increased thrust. Those engines, known as 117S, have been developed by NPO Saturn Research and Production Association. In terms of engineering, the engines are substantially modified AL-31F production engines employing fifth-generation technologies. They use a new fan, new high and low pressure turbines, and a new digital control system. A provision is made for using a vectored thrust nozzle. The modernization has increased the engine special mode thrust by 16%, up to 14,500 kgf. In the maximum burner-free mode it reaches 8,800 kgf. Compared to today’s AL-31F engines, their capabilities will grow substantially, by 2 to 2.7 times. For instance, the between-repair period will grow from 500 to 1,000 hours (the operating period before the first overhaul is 1,500 hours). The designed period will vary between 1,500 and 4,000 hours. The 117S engines will be co-produced by Ufa-based Motor Building Association and Rybinsk-based NPO Saturn Research and Production Association. The first production 117S engines were delivered to KnAAPO in early 2007 for testing on the first experimental Su-35 aircraft.

The impressive Su-35S is the latest incarnation of the T-10 family of fighter aircraft. It would be fair to describe this aircraft as the pinnacle of current conventional fighter design, blending a superb basic aerodynamic design with advanced engine, flight control and avionic technology. The designation Su-35 has been applied to two basic Flanker configurations since 1991. The first aircraft to carry the Su-35 label was the early 1990s digital T-10M/Su-27M Flanker E, powered by the Al-31FM engine and fitted with the Tikhomirov NIIP N011 planar array radar. Export configurations were designated Su-35. This aircraft was used as the basis of the Su-37 Flanker F advanced technology demonstrator, often labelled as the Super Flanker. The Su-37 was used as a platform to prove a modern glass cockpit, the N011M BARS PESA radar, thrust vector control engines and a quadruplex digital flgiht control system with an electrical sidestick controller. Much of the technology proven on the Su-37 migrated into the Su-30MKI/MKM Flanker H exported to Asia. The current Su-35S, ordered in 2009 for the Russian Air Force, was the result of a series of design studies for a deep modernisation of the Su-27M design. This was actually more of a deep re-engineering of the basic design in the manner of the F-15E against the F-15C performed during the 1980s. The new Su-35BM retained the basic aerodynamic design and much of the structural design of the late model Flanker, but sees important aerodynamic enhancements and completely new engines and digital systems. Notable changes include the removal of the dorsal speedbrake, additional internal fuel, and plumbing for AAR and external drop tanks. A quadruplex digital flight control system is used. The Item 117S engines, which use key components of the Al-41F supercruising core, are employed. The Su-35S is the first non-US fighter with substantial sustained supersonic cruise capability, which provides this aircraft with an enormous energy advantage against conventional opponents in most regimes of air combat. The avionic suite is fully digital. The centrepiece is the Tikhomirov NIIP N035 Irbis E (Snow Leopard) 20 kiloWatt class steerable hybrid ESA radar. A new glass cockpit is employed, using large area displays. The Khibiny electronic warfare suite is employed, with new wingtip DRFM technology jamming pods. The aircraft is intended to carry the full spectrum of Russian air to air and air to ground guided weapons. Given the large performance margin in the Su-35S design, it has considerable long term growth potential. It is likely that it will become the platform for the first Russian built large aperture AESA radars, as well as the R-172 very long range AAM.

The latest version of the Sukhoi Su-35, Su-35BM (bolshaya modernizatsiya - big modernisation), is an advanced capability multirole air superiority fighter developed from the Su-27. The aircraft has high manoeuvrability (+9g) with a high angle of attack and is equipped with high-capability weapon systems that contribute to the new aircraft's exceptional dogfighting capability. The maximum level speed is 2,390km/h or Mach 2.25. The Su-35BM was unveiled at the Aerosalon MAKS air show in Moscow in August 2007 and its first flight was in February 2008. The aircraft will enter service with the Russian Air Force in 2010-11 and Sukhoi has announced that the aircraft will be available for export deliveries in 2010-11. The aircraft is being developed, tested and introduced into serial production by the Sukhoi Design Bureau, based in Moscow, and will be manufactured by KNAPPO of Komsomolsk-on-Amur. Both companies are part of the Sukhoi Aviation Holding Joint Stock Company. The Russian Air Force ordered 48 Sukhoi Su-35S jets in 2009 with deliveries scheduled to run until 2015. Sukhoi began producing the components required for assembly of the aircraft in November 2009. The first aircraft will be delivered by end of 2010. The remaining deliveries in large numbers will begin in 2011. An information management system integrated with onboard subsystems and a new phased array radar system with long-range aerial target detection have been installed in the aircraft, which is currently undergoing preliminary testing. The cockpit has a central control column and is fitted with a Zvesda K-36D-3.5E zero-zero ejection seat which allows the pilot to eject at zero speed and at zero altitude. The aircraft has a quadruplex, digital fly-by-wire control developed by the Avionika Moscow Research and Production Complex JSC (MNPK Avionika). The cockpit is fitted with two 230mm×305mm high-resolution MFI-35 liquid crystal displays with a multifunction control panel and a IKSh-1M head up display with a wide 20°×30° field of view. The pilot has two VHF/UHF encrypted radio communications systems and a jam-resistant military data link system between squadron aircraft and between the aircraft and ground control. The navigation system is based on a digital map display with a strapdown inertial navigation system and global positioning system.

The Sukhoi Su-35 (Russian: Сухой Су-35, NATO reporting name: Flanker-E) is a single-seat, twin-engined supermaneuverable multirole fighter. It is a derivative of the Su-27 'Flanker', and was initially known as the Su-27M. More than a dozen of these were built with some used by the Russian Knights aerobatic demonstration team. The Su-35 had been offered to many countries, including India, Brazil and South Korea. In the 1980s, Sukhoi was looking to upgrade its high-performance Su-27. The resultant Su-35 embodies aerodynamic refinements to give it more manoeuvrability, greatly enhanced avionics, longer range, and a more powerful engine. The first prototype, converted from a production Su-27, made its maiden flight in June 1988. The Su-35 was further developed into the Su-37, which has thrust-vectoring capabilities, and the Su-35BM, classed as 4++ generation fighter by its manufacturer. The new model entered into serial production as the Su-35S for the Russian Air Force in 2010. In the early 1980s, while the Su-27 was entering service with the Soviet Air Force, Sukhoi looked to develop a follow-on variant. This variant, originally designated "Su-27M", would be much more agile and feature greatly improved avionics than the aircraft considered to be the best contemporary fighter. It was also to carry more armament to improve its capacity as an air-to-ground platform. The first Su-35UB (Bort 801) twin-seat trainer. It first flew a year earlier on 7 August 2000. 801 is visible on under the canopy and on the vertical stabilizer. Known within the design bureau as the "T10-M", development began in the early 1980s. The improved variant featured a host of changes regarding aerodynamic refinements, avionics and propulsion upgrades, construction methods, as well as increased payload carriage. High-strength composites and aluminium-lithium were used not only to reduce weight, but to boost internal fuel volume. Distinguishing features are the canards, which improve airflow over the wings, eliminating buffeting and allowing the aircraft to fly at a very high angle of attack of 120°, i.e., past the vertical. The canards are governed by a new digital fly-by-wire flight control system. It is outfitted with the Luylka Al-31FM engine, also found on the Su-34 tactical bomber. This powerplant is larger, more reliable, and with a thrust of 28,218 lbf (125.52 kN) is more powerful. Also new was the fire-control system, at the heart of which is the more powerful N-011 Zhuk-27 pulse-Doppler radar. The radar can track 15 aerial targets simultaneously and guide six missiles towards them. To exploit the improved radar, two additional underwing pylons were added. In the aircraft "stinger" is the Phazotron N-012 rear-ward facing radar, which effectively provides the aircraft impunity from attacks from behind. The aircraft can carry a variety of bombs and both air-to-air and air-to-surface missiles. Among the weapons it can carry include the R-27, R-73, R-77, Kh-29, Kh-59, Kh-31, KAB-500 and KAB-1500, along with napalm, dumb and cluster bombs. The cockpit was modernised, equipped with multi-function colour LCD screens, and the pilot sits on the K-36DM ejection seat inclined at 30° to improve g-force tolerance. Range is increased to 4,000 km (2,222 nmi) through additional fuel capacity; with the fitting of an aerial refuelling probe, range can be further extended. The aircraft is characterized by its twin nose wheel – as a result of higher payload – and larger tail fins with horizontal carbon fibre square-topped tips. The Su-27M (T-10S-70) prototype first flew on 28 June 1988 at the hands of Sukhoi Chief Test Pilot Oleg Tsoi. The first prototype differed slightly from later examples in: retaining standard Su-27 vertical stabilizers without the cropped top; lacking a fire-control system; having an unusual three-tone grey/blue camouflage scheme, along with minor differences. Designated T10M-1 to T10M-10, the first 10 prototypes were built by KnAAPO in conjunction with Sukhoi, as the Soviet aerospace system was different from Western structure. They slightly differed from another. Four were converted Su-27s and the others being new-builds. The second prototype started flight testing in January 1989, while the third followed in mid-1992. The prototypes were used to validate the new flight-control system and canard fore-planes.
