Development of Russia's LFI (logkiy frontovoi istrebitel) lightweight tactical fighter has been dramatically accelerated after the Russian Air Force decided its priorities for the next 10 years. Revealed here exclusively as the I-2000 (Istrebitel {fighter} 2000) project, the aircraft is due to become operational in 2005 as Russia's basic front-line fighter. It is also likely to become the leading export product of the Russian aircraft industry. Available information on the I-2000 indicates that it will be closely comparable to the US Joint Strike Fighter, operating in both the air-to-air and air-to-surface roles.
The aircraft comes from a long line of Mikoyan lightweight fighters, such as the MiG-15 and MiG-21. It is about the same size as the MiG-21 (shorter by 1.3m but wider by 4.5m), but noticeably smaller than its immediate predecessor, the MiG-29. Take-off weight is estimated at around 12 tonnes; maximum take-off weight at about 16 tonnes.

In early 2002 Sukhoi was chosen as prime contractor for the planned Russian fifth-generation fighter is called the PAK FA [ Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsyi - Future Air Complex for Tactical Air Forces]. This intermediate class twin-engined fighter will be larger than a MiG-29 and smaller than a Su-27.
The aircraft will feature a long combat radius, supersonic cruise speed, low radar cross section, supermaneuverability, and the ability to make short takeoffs and landings. In accordance with the technical requirements, the PAK FA will have a normal takeoff weight of 20 tons, which is close to the average normal takeoff weight of the two American airplanes, the F-35 JSF (17.2 tons) and the F-22 (24 tons). The new fighter (a medium version) will have a traditional wing form, though the experience gathered as a result of Berkut's test flights will be taken in consideration when designing the fighter. It is supposed that it will be created using the Stealth technology, and equipped with two AL-41F engines by the Saturn scientific and industrial enterprise, a radar system with an active phased array (to all appearances, it will be produced by the Fazatron-NIIR corporation), and high-precision weapons.
The government commission decided on 26 April 2002 to choose the Sukhoi holding company as the head company to develop and produce the fighter of the fifth generation. The prototype of the PAK FA would take-off in 2006 and that in 2010 the aircraft would be ready for series production. The first deliveries, both for Russian armed forces and for export, would be possible in 2011-12.
The new airplane is being proposed to be brought from the concept design to a prototype series in less than 9 years. Historically, fourth and fifth generation fighters have not been created in less than 15 years. The Russian government has promised to allocate 1.5 billion dollars for the PAK FA through 2010. But the Russian Air Force is receiving less than 200 million dollars a year during this period, and will spend it primarily on other needs.
The prices and sources of funding will determine the destiny of the whole program. To date officials agree that the program will cost $1.5 billion. However, $1.5 billion is the sum needed for creating a new generation of avionics for the fighter (considering the fact that pre-production models of the phased array have already been produced, and will soon be tested). Completion of the AL-41F engine (present readiness is 30 percent) will require, in the opinion of the boss of Rosaviakosmos, 600 - 800 million dollars. Saturn said that launching of production of the AL-41F engine would take $150 million. An improved version of the AL-31F will be used on the aircraft originally (though it is not clear how these heavy motors are reconciled with the concept of a 20-ton fighter). The upgrade of these engines will require expenditures of 1.2-1.5 billion dollars. And finally, designers will have to spend several hundred millions of dollars on creating a new airframe.
According to some reports, India and Russia have agreed to jointly develop this fifth-generation fighter, under a scheduled with entery into service in 2009. This would be the first such joint development venture between the two countries.

Specifications
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. It will be powered by the AL-41F engine or an advanced derivative of it. Reports indicate that it will be slightly larger than the MiG-29 but not as large as the Su-27.
The PAK-FA's competitor from United States will be the F-35. It is believed that the PAK-FA will offer similar capabilities, but at less cost.
Stealth
Top right: a PAK FA with plasma stealth activatedIt is uncertain how low the Radar Cross Section of the PAK-FA will be. However, this will be Russia's first attempt at making a "stealth" aircraft. And it is natural to assume, the stealther the aircraft, the higher its development costs and purchase price will be.
It is also unclear whether the PAK-FA will use conventional stealth, which is used by the USA and demonstrated in Mikoyan Project 1.42 / 1.44, or plasma stealth reported by some to have been successfully developed and used.
Units to be produced
The Russian Air Force is speculated to order around 1000 units of this fighter, since that is the approximate number of MiG-29s and Su-27s currently in service.
However it is said that India and China, as well as other countries such as Indonesia, may want to buy this fighter.
Exports
At this time, there are no confirmed orders for the PAK-FA. This is due to the fact the aircraft is still in its early stages of development.
India
Although reported disagreements between countries over whether the PAK-FA will be a twin engine aircraft (as wanted by Russia) or a single engine aircraft (as wanted by India) has stopped their co-operation on this project, it is likely that India will be buying an uncertain amount of units of this aircraft.
China
China is currently working on their own 5th generation fighter. If that project is unsuccessful, or does not live up to the standard set by the Chinese authorities, it is highly possible that they will too order an uncertain amount of units of this aircraft.
Indonesia
In an arms purchase in the year 2005, Indonesia has requested to order an uncertain amount of "Future Sukhoi Aircraft". While it is not certain whether this request was specifically of the PAK-FA, it appears to be very likely.
Other Countries
In 2005, the Russian Federation sold arms to 72 countries, and it is likely some European as well as Middle-Eastern countries will want to replace their aging fleets of MiG-29s and other planes with this new fighter.
