The PAK FA T-50 is in an entirely new league of fighter aircraft. PAK FA is short for Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii. When translated into English, it means “Prospective Airborne Complex of Frontline Aviation” or “Future Air Complex – Tactical Air Forces”. It is being developed by Russia to be a fifth generation stealth fighter with capabilities rivaling and even exceeding in some areas those of the American Lockheed F-22A, the first fifth generation fighter in the world. The finished prototype belonging to the Russian Air Force possesses advanced features like supercruise and extreme maneuverability and is expected to enter into service by 2015.

Origin of the PAK FA T-50
In the 1980s, Russia sought to develop a multirole fighter that could serve as a replacement for the MiG-29s as well as for the, then recently deployed, Su-27s. The MiG 1.44 was created through the MFI program. The program encountered repeated delays. Its first flight was behind schedule by nine years. By then, Sukhoi had already started developing the technology required for the next generation aircraft even though it was not a part of the MFI program. The development of MiG 1.44 was officially scrapped due to the lack of funds ensuing from the collapse of Soviet Union. At that point, Sukhoi was, after winning the PAK FA competition, chosen to lead the designing of a new fifth generation aircraft.
Since 2007, Russia and India have collaborated to jointly develop an Indian prototype of the T-50 stealth fighter. The program, initially known as FGFA (Fifth Generation Fighter Aircraft) is now jointly called the PMF (Perspective Multirole Fighter). India has agreed to bear half the cost of the projected $12 billion. Two separate prototypes are expected to be developed in the process – one each by India and Russia. India is expected to buy over 144 single seater PAK FAs while Russia is expected to order over 150.
Timeline for the PAK FA T-50
- The initial design for PAK FA was completed in 2004.
- The first public flight was in January 2010 and lasted 47 minutes.
- In August 2012, flight testing of the AESA radar suite was started.
- In June 2014, a prototype T-50 caught fire during landing. However, Sukhoi has stated that this incident “will not affect the timing of the T-50 test program”.
PAK FA T-50 Design
Due to the secrecy surrounding PAK FA project, there is not much substantiated information available regarding the design and development of the T-50 prototype. However, it is clear that it will be the first aircraft in the Russian Air Force that is stealthy. Besides stealth, this fighter aircraft will also possess other advanced features. Among them is a highly advanced radar system called the advanced phase array radar that adds the capacity for both, forward looking as well as side scanning. Its sensor fusion capability will allow it to track and engage with multiple targets at the same time. The current PAK FA prototypes that are scheduled to go into service will use the izdeliye 117 engine. These powerful engines will allow the aircraft to supercruise; that is, sustain a supersonic flight without the use of afterburners.
The armament details of the PAK FA have been kept largely under wraps. However, it is believed that the current T50 prototype could be equipped with air to surface missiles, air to air missiles, anti ship missiles, anti radiation missiles, and guided bombs. When the prototype comes into service, it may use the in-service missiles. However, it is expected that over time special munitions will be developed specifically to be used in the PAK FA family.
In certain aspects of design, the PAK FA does resemble the existing American fifth generation F-22s, notably in its broad shape and long lines. Its advanced aerodynamic system gives it extreme agility, a trait that is somewhat lacking in the F-22s. The 25,000 lb internal fuel load gives it another edge over the F-22s when it comes to combat persistence.
The Political and Strategic Impact of the PAK FA
A technical analysis of the PAK FA shows that is clearly more advanced in agility and aerodynamic performance than any aircraft built by the USA, whether in service currently or in planning. Given the configuration of the PAK FA and its stealth parameters, it is believed that it will change the nature of missile combat. The missile will come into the combat at a closer range than before, and the timeline of actual engagement will be shorter as well. This means that stealth will be one of the most important features for fighter aircrafts in the time to come. The other factor most likely to affect the outcome of the air combat would be the ability of the fighters to supercruise for longer periods of time. As such, the advent of the mature production PAK FA could mean the end of line for the teen series generation aircrafts such as F-15 / F-16 / F/A-18.
Even when it comes to the current fifth generation American fighter F-22A, the United States will not have a clear and certain advantage when it comes to air strikes and will immediately lose the ability to impose air superiority rapidly. According to the tactical analysis, “Fights between the F-22A and the PAK FA will be close, high, fast and lethal …The outcome will be difficult to predict as it will depend a lot on the combat skills of the pilots and the capabilities of the missiles for end-game kills. There is no guarantee that the F-22 will prevail every time.”
Summary
PAK FA T-50 is believed to be the one of the foremost “game changers” in the field of fighter technology since T-10 & Su-27s. Its impact is not just limited to technology and politics, but rather it could have fundamental ramifications tactically, strategically, as well as operationally. Most importantly, it challenges the aerial advantage that the United States has held for many decades. Unless their planning for future air power tactics changes immediately and drastically, United States will have fewer strategic options going forward that are nonnuclear in nature. The PAK FA T-50 is certainly a counter punch that will cause the US to innovate an even better fighter than the F-35 and F-22.
