Unlike the only U.S. air superiority stealthy aircraft, it is planned that the Russian Sukhoi T-50 PAK FA will be offered for export.  Its selling price should be around US$60 million.  It is anticipated that total development cost for the Sukhoi T-50 PAK FA project will be around US$10 billion.

To date Russia's stealth Sukhoi T-50 PAK FA, sometimes referred to as the FG FA, is in the prototype flight testing stages. A total of five prototype aircraft have performed some 500 test flights to date. It is being developed as a supersonic stealthy fighter/bomber that will replace a number of aging Russian aircraft.

The origins of the Sukhoi T-50 PAK FA date back to 1989 when the then Soviet Union decided on a strategy of combining technology used on current fighter jet aircraft with the latest advances in super cruise and stealth engineering.

The project saw considerable delays with the break up of the Soviet Union and ensuing financial problems. Once funding for the program was reestablished, additional delays were encountered in the development of avionics and engine technology.

The first prototype Sukhoi T-50 PAK FA flew on January 29, 2010. Four additional prototype Sukhoi T-50 PAK FA aircraft have now joined it. The Sukhoi T-50 PAK FA made its first public appearance at the MAKS 2011 Air Show on August 17, 2011.

We are told that the design of the Sukhoi T-50 PAK FA presents a minimal target for radar while enabling maximum maneuverability throughout its flight envelope. Its overall handling characteristics enable high alpha flight angles. The use of its fuselage as a lifting body facilitates high altitude maneuverability. About one quarter of the aircraft is built from composite materials, to resist degradation by high temperatures generated at supersonic aircraft speeds, for higher strength, lower weight, and corrosion resistance.

Initial analysis of the Sukhoi T-50 PAK FA shows that, at least primarily, it may not be as stealthy as American fifth generation fighters. Of particular interest are the wing leading edge and engine intakes. If they remain unchanged, the aircraft will probably present a slightly larger radar signature than the U.S. fighter aircraft.

The digitally controlled twin engines of the Sukhoi T-50 PAK FA allow super cruise flight, while giving it the potential of top speeds in the 1,600 + MPH range.  Each engine has independently operated thrust vectoring exhaust nozzles for increased maneuverability.

The total internal fuel of the Sukhoi T-50 PAK FA has been estimated to be around 23,000 lbs., giving the aircraft a long range. It is also equipped for in-flight refueling.

Internal weapons bays of the Sukhoi T-50 PAK FA suggest that they should be able to carry a combination of missiles and up to ten 1,000 lb. smart bombs per weapons bay. There are currently no indications of external hardpoints or missiles being carried on the tips of the wings, but there will most likely be provisions for up to six hardpoints under the aircraft's wings when not flying in stealth mode. The Sukhoi T-50 PAK FA appears to have a weapons bay in each wing capable of holding a single short range air-to-air missile.

It has been revealed that the aircraft is intended to be equipped with the K-77M air-to-air missile. The missile has an active phased array detection system and is said to possess an almost instantaneous reaction time to any evasive maneuvers its target may try while attempting to evade it.

It appears that there is a provision for a cannon in the nose of the fuselage.

The cockpit of the Sukhoi T-50 PAK FA is coated with a special composite material that minimizes its radar signature. The latest computerized avionics used by the Sukhoi T-50 PAK FA are designed to reduce the pilot work load in order that full mission engagement is provided. Full tactical analysis is provided in real time to the pilot through an array of color monitors. The information is also available for instant analysis through a data exchange network synchronized to ground control. Data detection is through an array of antennas producing variable radiation patterns with actively modified output energy. These are designed to maximize acquisition of desired targets through a common data feed.

It is anticipated that along with Russia's most advanced avionics, the Sukhoi T-50 PAK FA will carry both L band and X band radars. It is also possible that it will be equipped for electronic warfare. However, current thinking is that its primary mission will be for use as a stealthy fighter/bomber.

The Indian government is contributing heavily to the development of the aircraft. The Sukhoi T-50PAK FA will be built by HAL in India. Eventually the aircraft will be flown by the Indian Air Force.

Russia anticipates placing an initial order for 150 Sukhoi T-50 PAK FA aircraft. Current projections are that production aircraft will be flying by late 2016 or early 2017.

A number of airplane hobby companies are scrambling to produce their first Sukhoi T-50 Sukhoi T-50 PAK FA airplane. Based on past experience, these are what we think you can expect.

NitroPlanes will probably have a Sukho T-50 Sukhoi T-50 PAK FA made by CMP similar to the aircraft shown in the picture immediately above. Wingspan of the ARF should be 31 1/2 in. and length about 41 1/2 in. A pair of brushless motors turning minimum 55 mm fans should power it. Weigh will be about 28 1/2 oz.

We received the following email from Bob Cundiff aka, bobdaeronort: "Here I am in my little corner airplane shop with my Sukhoi T-50 Sukhoi T-50 PAK FA on my right.  It is 45 in. long with a 34 in. wingspan and the J-20 is 47 in. long with a 34 in. wingspan. Power is with a Grayson Hobby Super MegaJet 2550kv motor spinning a 7x5 prop. Free PDF plan download file links for my planes are posted on my "bobdaeronort" You Tube channel page."  Thank you, Bob. We are sure that lots of folks will appreciate those free plans.

Pictured just above is what a Sukhoi T-50 Sukhoi T-50 PAK FA could look like from Blitz. The ready to fly model should have a wingspan of 34 1/2 in. and a length of 56 1/2 in. Typical is for Blitz to offer the model with a single brushless motor driving a 70 mm ducted fan. Weight should be around 40 oz.
