The Sukhoi PAK FA (Russian: Перспективный авиационный комплекс фронтовой авиации, Perspektivny aviatsionny kompleks frontovoy aviatsii, literally "Prospective Airborne Complex – Frontline Aviation") is a twin-engine jet fighter being developed by Sukhoi OKB for the Russian Air Force.
The current prototype is Sukhoi's T-50.[12] The PAK FA, when fully developed, is intended to be the successor to the MiG-29 and Su-27 in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA being developed with India.[13][14] A fifth generation jet fighter, the T-50 performed its first flight 29 January 2010.[3][15] Its second flight was on 6 February and its third on 12 February 2010. As of 31 August 2010, it had made 17 flights and by mid-November, 40 in total. The second prototype was to start its flight test by the end of 2010, but this was delayed until March 2011.[16][17][18][19][20]
Sukhoi director Mikhail Pogosyan has projected a market for 1,000 aircraft over the next four decades, which will be produced in a joint venture with India, two hundred each for Russia and India and six hundred for other countries.[21] He has also said that the Indian contribution would be in the form of joint work under the current agreement rather than as a joint venture.[22] The Indian Air Force will "acquire 50 single-seater fighters of the Russian version" before the two seat FGFA is developed.[23] The Russian Defense Ministry will purchase the first 10 aircraft after 2012 and then 60 after 2016.[24][25] The first batch of fighters will be delivered without the "Fifth generation" engines.[26] Ruslan Pukhov, director of the Centre for Analysis of Strategies and Technologies, has projected that Vietnam will be the second export customer for the fighter.[27] The PAK-FA is expected to have a service life of about 30–35 years.

In the late 1980s, the Soviet Union outlined a need for a next-generation aircraft to replace its MiG-29 and Su-27 in frontline service. Two projects were proposed to meet this need, the Sukhoi Su-47 and the Mikoyan Project 1.44. In 2002, Sukhoi was chosen to lead the design for the new combat aircraft.[28]
The Tekhnokompleks Scientific and Production Center, Ramenskoye Instrument Building Design Bureau, the Tikhomirov Scientific Research Institute of Instrument Design, the Ural Optical and Mechanical Plant (Yekaterinburg), the Polet firm (Nizhniy Novgorod) and the Central Scientific Research Radio Engineering Institute (Moscow) were pronounced winners in the competition held in the beginning of 2003 for the development of the avionics suite for the fifth-generation airplane. NPO Saturn has been determined the lead executor for work on the engines for this airplane.
The Novosibirsk Chkalov Aviation Production Association (NAPO Chkalov) has begun construction of the fifth-generation multirole fighter. This work is being performed at Komsomol'sk-on-Amur together with Komsomolsk-on-Amur Aircraft Production Association; the enterprise's general director, Fedor Zhdanov reported during a visit to NAPO by Novosibirsk Oblast's governor Viktor Tolokonskiy on 6 March 2007. "Final assembly will take place at Komsomol'sk-on-Amur, and we will be carrying out assembly of the fore body of this airplane", Zhdanov specified.
On 8 August 2007, Russian Air Force Commander Alexander Zelin was quoted by Russian news agencies that the development stage of the PAK FA program is now complete and construction of the first aircraft for flight testing will now begin.[29] Alexander Zelin also said that by 2009 there will be three fifth-generation aircraft ready. "All of them are currently undergoing tests and are more or less ready", he said.[30] In the summer of 2009 the design was approved.[28]
On 11 September 2010, it was reported that Indian and Russian negotiators had agreed on a preliminary design contract that would then be subject to Cabinet approval. The joint development deal would have each country invest $6 billion and take 8 to 10 years to develop the FGFA fighter.[31] The agreement on the pre-design of the fighter was to be signed in December 2010.[32] The preliminary design will cost $295 million and will be complete within 18 months.[33]

Flight testing

On 28 February 2009, Mikhail Pogosyan announced that the airframe for the aircraft was almost finished and that the first prototype should be ready by August 2009.[34] On 20 August 2009, Sukhoi General Director Mikhail Pogosyan said that the first flight would be by year end. Konstantin Makiyenko, deputy head of the Moscow-based Centre for Analysis of Strategies and Technologies said that "even with delays", the aircraft would likely make its first flight by January or February, adding that it would take 5 to 10 years for commercial production.[35]
The maiden flight had been repeatedly postponed since early 2007 as the T-50 encountered unspecified technical problems. Air Force chief Alexander Zelin admitted as recently as August 2009 that problems with the engine and in technical research remained unsolved.[36]
On 8 December 2009, Deputy Prime Minister Sergei Ivanov announced that the first trials with the fifth-generation aircraft would begin in 2010.[37] The testing, however, has commenced earlier than stated, with the first successful taxiing test taking place on 24 December 2009.[38][39][40]
The aircraft's maiden flight took place on 29 January 2010 at KnAAPO's Komsomolsk-on-Amur Dzemgi Airport; the aircraft was piloted by Sergey Bogdan (Сергей Богдан) and the flight lasted for 47 minutes.[3][41][42] [43]
A second airframe was first planned to join the flight testing in the fourth quarter of 2010 but was postponed. On 3 March 2011 a second prototype was reported to have made a successful 44 minutes test flight.[16] These first two aircraft will lack radar and weapon control systems, while the third and fourth aircraft, to be added in 2011, will be fully functional test aircraft.[44]
On 14 March 2011, the aircraft achieved supersonic flight at a test range near Komsomolsk-on-Amur in Siberia.[45]
The T-50 is expected to be on display at the 2011 MAKS Airshow.[46]

Naval version

Navalized Sukhoi T-50 PAK FAs will be deployed on the Russian aircraft carrier Admiral Kuznetsov and future Russian aircraft carriers.[47] There will be a competition between the Sukhoi, Mikoyan and Yakovlev design bureaus to choose the new naval aircraft.[48]

Light fighter

Alexei Fedorov has said that any decision on applying fifth generation technologies to produce a smaller fighter (in the F-35 range) must wait until after the heavy fighter, based on the T-50, is completed.[49]


Although most of information about the PAK FA is classified, it is believed from interviews with people in the Russian Air Force and Defense Ministry that it will be stealthy,[9] have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, incorporate a fix-mounted AESA radar with a 1,500-element array[50] and have an "artificial intellect".[51]

According to Sukhoi, the new radar will reduce pilot load and the aircraft will have a new data link to share information between aircraft.[52]
Composites are used extensively on the T-50 and comprise 25% of its weight and almost 70% of the outer surface.[44] It is estimated that titanium alloy content of the fuselage is 75%. Sukhoi's concern for minimizing radar cross-section (RCS) and drag is also shown by the provision of two tandem main weapons bays in the centre fuselage, between the engine nacelles. Each is estimated to be between 4.9-5.1 m long. The main bays are augmented by bulged, triangular-section bays at the wing root.[53]
The Moskovsky Komsomolets reported that the T-50 has been designed to be more maneuverable than the F-22 Raptor at the cost of making it less stealthy than the F-22.[54] One of the design elements that have such an effect is the Leading Edge Vortex Controller (LEVCON).


The PAK FA SH121 radar complex includes three X-Band AESA radars located on the front and sides of the aircraft. These will be accompanied by L-Band radars on the wing leading edges.[55][56] L-Band radars are proven to have increased effectiveness against very low observable (VLO) targets which are optimized only against X-Band frequencies, but their longer wavelengths reduce their resolution.
The PAK FA will feature an IRST optical/IR search and tracking system, based on the OLS-35M which is currently in service with the Su-35S.
Hindustan Aeronautics Limited will reportedly provide the navigation system and the mission computer.[54][dubious ]


The PAK FA was expected to use a pair of Saturn 117S engines on its first flights. The 117S (AL-41F1A) is a major upgrade of the AL-31F based on the AL-41F intended to power the Su-35BM, producing 142 kN (32,000 lb) of thrust in afterburner and 86.3 kN (19,400 lb) dry. In fact, PAK FA already used a completely new engine in its first flight, as stated by NPO Saturn.[57] The engine is not based on the Saturn 117S and is rumoured to be called "127 engine".[58] The engine generates a larger thrust and has a complex automation system, to facilitate flight modes such as maneuverability. Exact specifications of the new engine are still secret. It is expected that each engine will be able to independently vector its thrust upwards, downward or side to side. Vectoring one engine up with the other one down can produce a twisting force. Therefore the PAK FA would be the first fifth generation fighter with full 3-D thrust vectoring along all three aircraft axes: pitch, yaw and roll. These engines will incorporate infrared and RCS reduction measures.[59][60]


The PAK FA has a reported maximum weapons load of 7,500 kg.[61] It has an apparent provision for a cannon (most likely GSh-301). It could possibly carry as many as two 30 mm cannons.[26] It has two internal bays estimated at 4.6-4.7 metres by 1-1.1 metres.[62] Some sources suggest two auxiliary internal bays for short range AAMS and six external hardpoints.
Two Izdeliye 810 Extended beyond visual range missiles per weapons bay. Multiple Izdeliye 180 / K77M beyond visual range missiles. K74 and K30 within visual range missiles can also be carried.[62] Two KH38M or KH58 USHK air-to-ground missiles per weapons bay. Multiple 250–500 kg precision guided bombs per weapons bay,[62] with a maximum of 10 bombs in internal bays.[61] Other possible loads include one 1,500 kg bomb per weapons bay or two 400 km+ range anti-AWACS weapons on external hardpoints.[63]

Operational history


The first flight video shows that PAK FA has no conventional rudders, its vertical tails are fully movable.[64] This special tail fin design is mechanically similar to V-tails used by the Northrop YF-23 in 1990s,[65] but is supplemented by dedicated horizontal stabilators (as on the F-22). The T-50 has wing leading-edge devices above the jet engine intakes that have been called a challenge for signature control.[66]


Because the aircraft is in development, these specifications are preliminary and are taken as estimates from the available images.

  1. DPR komisi 1 berbicara pemborosan.......apa manfaatnya...ngak mudeng kali...pertahanan kedepan dibangun dengan daya getar.....bukan perang....dan ini ada berkaitan dengan daerah terluar yang sering diganggu...jelas dong pasti ada manfaatnya... nah kalau bicara manfaatnya, apa manfaatnya gedung DPR (1 trilyun lebih) buat negara ini.....kayaknya besok2 ngak usah ngomong deh......memalukan sebagai wakil rakyat...

  2. TNI AU perlu melengkapi diri dengan Sukhoi PAKFA bukan dengan F5E yang sudah ketinggalan teknologi. sebagai negara besar harus mempunyai alutsista yang paling unggul dan mampu untuk menjaga wilayah NKRI yang luas agar negara lain tidak berani dan gentar untuk coba-coba mau merebut sejengkalpu wiloayah NKRI

  3. ngga ada manfaatnya gedung DPR 1 triliun besok2 jng dipilih lg wakil rakyat yg muka tembok otaknya oon

  4. Pak Pres kita hrs punya 1 skadron sukhoi PAK FA, melihat situasi wilayah sekitar NKRI semakin tdk menggembirakan dg adanya kasus Sabah dan ke depan bila Bapak sdh pensiun masih akan ada daya gentarnya Tentara Udara NKRI. Salam...berjuang.
