The Sukhoi T-50 is a Russian fifth generation fighter developed by Sukhoi Aviation under the PAK FA project, designed to counter the F-22 Raptor and its sister fighter the F-35 Lightning II in the international market, the T-50 isn't fully developed, but is planned to replace the MIG-29 Fulcrum and the Su-27 Flanker.

After the debut of the F-117 Nighthawk and the YF-22 Lightning II by the United States, the Soviet Union began work on what would be its own stealth aircraft.

However, most of its military investment projects were abruptly ended after the Soviet Union's collapse. Part of the industrial structure and technique that was saved was in Russia, and was used to initiate an attempt to keep at least part of which had been adrift. One of the projects given priority was to develop a new aircraft for the Russian air force, trying to follow the path suggested by the Americans, developing large-capacity aircraft with stealth before the enemy radar. The first flight of the aircraft known as Sukhoi T-50, and that is the result of a program called PAK-FA ' Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy 'or' Study of aerial system for frontal aviation took place on January 29, 2010. Several hypotheses have been initially presented as' concepts 'to the Russian authorities. The variety of artistic visions that went to press, was a mirror of the wide variety of options that presented themselves.

Among the issues to be resolved by the Russian authorities, was the degradation of productive structures and industries related to defense. The production of a revolutionary aircraft, which had been studied for example in the form of Su-47 Berkut was not only too expensive, and above all would take a huge development. Placed within this dilemma, the Russian authorities approved in 2006 a project design PAK -FA would become the final draft, from which the aircraft will be developed to the stage of production. Apparently, the base configuration of the PAK -FA, based on the Su-27 Flanker, very changed. The option was the most logical view of the known difficulties in Russia. When you choose the configuration that was shown at the end of January 2010 the Russians have opted for an aircraft on Stealth, but that will not fail to mark the presence in the Russian market. The new engine used by the aircraft, is the 117S, a derivative of AL-31 engine. This is an already traditional in Flanker aircraft type and is known to be extremely spender, because of the high performance aircraft. But an aircraft with less speed and enhanced for the 'concealment' spend less and need less fuel.

The exact power of the engines is also unknown. Most data points to a power 29000kgf. In any case it is certain that the plane will be capable of 'supercruise, that is the ability to fly faster than the speed of sound, without triggering the post-combustion systems, which greatly increase the consumption and make the plane very more "visible" . The maximum speed of an aircraft Stealth is not the most important factor. The Su-27 has been 'refined' so as to take advantage of the power of their engines, but the PAK/FA has to contend with other problems such as the aircraft configuration to reduce the radar signature. Both are difficult to reconcile. Typically, the aerodynamic enhancement leads to better performances, but the improvement to reduce the silhouette in the enemy radar is not the best in terms of aerodynamics.

Preliminary data released by the Russian press, to indicate that the aircraft will have less autonomy maximum (5.500 km to 8.000 km against the Su-27) a

lso point towards a lower aerodynamic efficiency, greater effort of the engines. The value of 5.500 appears to be very conservative, especially considering that the aircraft must have a maximum.

The reduction in the autonomy of the PAK-FA but should not be just the aerodynamics, but the need to carry weapons inside compartments that are blocked when the plane flies. The space that hold these magazines, will reduce the available space for additional fuel.

Naval VersionEdit

Navalized Sukhoi T-50 PAK FAs will be deployed on the Russian aircraft carrier Admiral Kuznetsov and future Russian aircraft carriers. There will be a competition between the Sukhoi, Mikoyan and Yakovlev design bureaus to choose the new naval aircraft.[43]
