Production :
In 1980s, Su-27 entered service with the Soviet Air Forces. On the mean time Sukhoi looked to develop a follow-on variant. Originally designated "Su-27M", it would be much more better and powerful .It had improved air to ground weaponary capabilities.Aluminium-lithium alloys were used to reduce weight and boost internal fuel volume.The aircraft was fitted with Turbofan engine which is much more powerful ,bigger and reliable .Range was increased to 4,000 km.The Su-27M prototype first flew on 28 June 1988 piloted by Sukhoi chief test.Two more prototypes were made designated as T-10M1 and T10-M2. The third prototype, T10M-3, appeared at the Dubai Airshow in 1993, by which time Sukhoi had re-designated its fighter the "Su-35".In total, 15 airworthy Su-35s were produced, including an Su-35UB two-seat prototype, along with two static test prototypes. The Su-35UB,made its first flight on 7 August 2000. It was demonstrated to South Korea during that country's F-X replacement fighter tender.
Design work on SU-35 had been completed by 2007.On 19 February, Sukhoi test pilot took the aircraft aloft for its first flight from Zhukovsky, accompanied by an Su-30MK2 acting as a chase plane . During the 55-minute flight, the Su-35 reached a height of16,000 ft, and tests were carried out on its stability, controllability and engines.The Su-35S's estimated price was $40 million each. In November 2009, KnAAPO started manufacturing the first serial aircraft; Sukhoi estimated that 24 to 30 aircraft would be produced each year from 2010 to 2020. On 11 October 2010, the first production Su-35S had completed.It made its debut in 2014 in an airshow The fighters will be delivered at a rate of 10 aircraft per year starting in 2016.
There have been two different Sukhoi Su-35s in the aviation history; they even look different. The first jet fighter to get this designation in the early 1990s at international trade shows was an aircraft also known as Sukhoi Su-27M.
The earlier Su-35 was a comprehensive upgrade of the basic Su-27. In fact, that was the first attempt to make a multi-role fighter out of the interceptor jet.
Then the upgraded Su-27 was given new capabilities to control guided precision weapons. To enable this capability, a new airborne radar was installed on the jet. The weapons control system and the airframe were also modified, adding a canard wing.
For a number of reasons, that jet did not go into production, and the manufacturer did not resurrect the Su-35 designation until 2005. The new Sukhoi Su-35 took off from the Ramensky Airfield of the Gromov Flight Research Institute in February 2008.
The fighter jet was originally designated Sukhoi Su-35BM (the Russian index for “big modernization,” or “a major upgrade”), and was subsequently renamed as Su-35 for the export markets. After the Russian Air Force became interested in the new model, a Sukhoi Su-35S variant emerged, with the index S traditionally signifying a version designated for the Russian Defense Ministry. At that point the Thirty-Five became the “poster boy” for the Russian combat air force: the defense contract for 48 Sukhoi Su-35S fighters was the largest procurement deal for new combat aircraft. The Russian Defense Ministry is planning to sign another procurement deal for the aircraft next year. The Thirty-Five offers a feature set and performance making it very nearly a Fifth-Generation fighter jet. The Su-35S falls short on only two requirements: lack of stealth technology and APAR (active phased array radar). The Sukhoi Su-35S carries a 30mm cannon, has 12 hard points and can detect targets at more than 400 kilometers, while its radar can track up to 30 targets simultaneously. The fighter has range in excess of 3,500 kilometers without refueling. The world’s most powerful Fourth-Generation fighter’s standout features include new engines, avionics and radar.
Use of high-thrust engines is a significant differentiator of Sukhoi Su-35 from predecessor Su-27 family jets. The new engines were developed by NPO Saturn, a UEC subsidiary, and are known under the 117S designation.
The new engines are essentially a deep upgrade of production AL-31F engines, with fifth-generation technologies used in the upgrade. The upgrade has increased the engine’s thrust by 16% to 14,500 kgf with afterburners and to 8,800 kgf maximum dry thrust. The engine has a significantly improved expected life (by a factor of 2x – 2.7x) compared to the production AL-31F: from 500 to 1,000 hours between repairs (and to 1,500 hours running time before the first overhaul), with the total expected life increasing from 1,500 to 4,000 hours.
Two engine manufacturers – the Ufa Engine Manufacturing Company (UMPO) and Rybinsk-based NPO Saturn – will manufacture 117S engines in cooperation with each other. The manufacturing partners, NPO Saturn and UMPO, have decided to share equally the scope of work to manufacture 117S engines.
The avionics used in the new jet are a completely new system of onboard electronics. The entire complement of Sukhoi Su-35 electronics is integrated into a single system. Avionics and other equipment are integrated into a single cohesive system by an information processing and control system, which comprises two digital CPUs, interface and data conversion systems, and a head-up display (HUD) implementing the glass cockpit concept. The Su-35 has two MFI-35 large color multi-functional LCDs, a multi-functional panel with an integrated display processor, a wide-angle collimated head-up display superimposed over the windscreen and a control panel in the cockpit.These indicators and a range of other avionics systems of the aircraft were developed by the Ramenskoye Instrument Design Bureau, also a Concern Radioelectronic Technologies (KRET) subsidiary. KRET engineers also designed a new navigation system for the fighter jet – the BINS-SP-2 strap-down inertial navigation system. The navigation system can identify the aircraft’s location independently from satellite positioning and without communicating with ground-based systems, at accuracy levels double those offered by earlier versions. BINS-SP-2 has an expected operating life of 10,000 hours, nearly double that of currently available comparable navigation systems. Incidentally, this state-of-the-art navigation system, created from scratch by KRET subsidiaries, will be also used in the Fifth-Generation advanced front-line aircraft system.
IRBIS Radar :
While lacking an APAR, the Su-35 radar system can detect targets at distances up to 400 kilometers, as well as tracking up to aerial targets and engage up to eight of these targets simultaneously. Sukhoi Su-35S has owes these capabilities to its new Irbis phased-array radar control system. The system was developed by Tikhomirov Instrument Engineering Research Institute, a KRET subsidiary, and is being manufactured by the Ryazan State Instrument Factory, another subsidiary of KRET. The state-of-the-art system enables Sukhoi Su-35S to detect quickly and track simultaneously up to four ground targets or up to 30 airborne targets, as well as engaging up to eight airborne targets at the same time. Besides, the radar control system has the friend-or-foe identification capability for aerial and maritime objects, is capable of identifying the class and type of airborne targets and take aerial photos of the ground. The system can be used in any weather at any time of the day, and remain effective in the face of interference, either natural or organized by the enemy electronic warfare systems. This puts the Sukhoi Su-35S radar system on par with the best state-of-the-art international designs, and ahead for most US and European active and passive phased array radars.
First Crash :
On 26 April 2009, the fourth Su-35 prototype was destroyed at Dzemgi Airport during a taxi run. The aircraft crashed into a barrier at the end of the runway, burned, and was written off. The pilot, Yevgeny Frolov, ejected and was taken to hospital with burns and other injuries.The aircraft was expected to be the third flying prototype, with its first flight scheduled on 24 April, which was rescheduled for 27 April.A commission was opened to investigate the crash, but several sources initially speculated that the incident had been the result of a brake failure or a faulty fuel pump.

In 2006, China was showing interest in the modernized Su-35, and was negotiating with Moscow for a purchase of the fighter.On March 2013, it was reported that Russia and China sides had signed an initial agreement for 24 fighters worth $2 billion, was signed. The first aircraft was delivered to China in 2016.
