The PAK FA (or PAK-FA), also known as the Sukhoi Su-50 is a fifth-generation fighter jet which is being developed by Russia. The PAK FA is being developed by a consortium of companies spearheaded by Sukhoi OKB. It stands for Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsyi (Перспективный авиационный комплекс фронтовой авиации in Russian) which means Future Air Complex for Tactical Air Forces. Sukhoi's internal project codename is T-50. The PAK FA is intended to replace the MiG-29 Fulcrum and Su-27 Flanker in the Russian Air Force. It is scheduled to have its first flight in 2008^[2]and enter service with the Russian Air Force subsequently. It will face direct competition from the F-22 Raptor.

Development

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. The PAK FA (or Sukhoi T-50) will incorporate technology from both the Su-47 and the MiG 1.44. The 1980s refers to the years from 1980 to 1989. ...

The Novosibirsk Chkalov Aviation Production Association (NAPO) has begun construction of the fifth-generation multirole fighter. This work is being performed at Komsomol'sk-on-Amur together with the aircraft plant at Komsomol'sk-on-Amur; 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. The fifth-generation fighter, which will replace the MiG-29 and Su-27 airplanes of the previous generation, was developed by the Sukhoi design bureau.

NAPO Chkalov also has been realizing serial production of the newest Su-34 Fullback multirole bomber since last year. According to the governor, the oblast's government will adopt a complex of measures for supplemental governmental support to NAPO in the very near future. As of today, the most severe problem at the enterprise is personnel. "In the 1990s, many highly-qualified workers were let go under the conditions of a slump, and now time is needed for training new ones. Our assistance will be in the resolution of personnel questions, and also in the provision of lodging for the enterprise's specialists," governor Tolokonskiy said in this connection.

According to reports in the Indian media, Russia and India had agreed in early 2007 to study a joint 5th-generation fighter project.^[6][7] On October 27, 2007, Asia Times quoted Sukhoi's director, Mikhail Pogosyan, "We [India and Russia] will share the funding, engineering and intellectual property [of the new project] in a 50-50 proportion."^[8] The Indian version, according to the deal, will be different from Russian version and specific to Indian requirements.^[9].

Design

The Sukhoi Su-47 (S-37) experimental aircraft (PAK FA Technology demonstrator)

Although there is no reliable information about the PAK FA's specifications yet, it is known from interviews with people in the Russian Air Force that it will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate an AESA radar. The PAK FA will use on her first flights 2 Saturn 117S engines (about 14.5-ton thrust each). The 117S is an advanced version of the AL-31F, but built with the experience gained in the AL-41F program. The AL-41F powered the Mikoyan MFI fighter (Project/Article 1.44). Later versions of the PAK FA will use a completely new engine (16⁺-tn thrust), developed by NPO Saturn or FGUP MMPP Salyut. Clearly, the use of such powerful engines demonstrates that the PAK FA will be a heavy-class fighter, comparable to F-22 Raptor, but analysts will have to wait till late 2007 for official disclosure of the design.^{[citation needed]}

Stealth

It is uncertain how small the Radar Cross Section (RCS) of the PAK FA will be. All latest production variants of Mikoyan, Sukhoi and Tupolev military aircraft use Radar Absorbent Materials (RAM) that lower RCS to that of less than 1 m² objects. And it is natural to assume, the stealthier the aircraft, the higher its development costs and selling price will be.
