Su-57 (PAK FA T-50) latest news 2019
Su-57 (factory designation T-50) is a fifth-generation Russian multirole fighter, developed by the P. O. Sukhoi Design Bureau as part of the PAK FA (Advanced Aviation Complex of Frontline Aviation) project (I-21 program). Until August 2022, the aircraft was known under the factory designation T-50. On August 11, 2022, the Commander-in-Chief of the Aerospace Forces of the Russian Federation, Viktor Bondarev, for the first time officially announced the serial name of the fifth-generation fighter T-50. The aircraft was designated Su-57.
History of creation
The PAK FA T-50, or the advanced front-line aviation complex, is a prototype of the domestic fighter of the latest fifth generation Su-57, developed by the Sukhoi Design Bureau. For 2022, several test samples of the machine with the first stage engine are known. However, a more advanced engine has already been developed, which will be installed on production aircraft in 5–7 years.
Work on creating a fifth-generation fighter began in 2001, when Rosaviakosmos and the Ministry of Defense developed a joint program to develop the latest aircraft. Development work was entrusted to the State Unitary Enterprise "APVK Sukhoi". It was planned that serial production and large-scale delivery of the aircraft to Russian troops would begin in full by 2015, however, for unknown reasons, there were significant delays in the development of the aircraft, which is why, among other things, India withdrew from the program for financing and purchasing aircraft of this project.

Many foreign experts regarded this step as a potential failure of the program to develop the latest generation fighter. However, the fate of the Su-57 today promises to be very promising. According to V.V. Putin, who very highly assessed the prospects of the new fighter, domestically produced serial aircraft will cost the army at least half as much as foreign ones, and therefore a decision was made to continue development.
Considering the novelty of the development, the name of the chief designer, as well as many of the technical characteristics of the machine, are unknown today.
The first tests of the Su-57 aircraft (then T-50) took place at the beginning of 2010. The flight lasting 45 minutes was carried out by Honored Test Pilot Sergei Bogdan. The following year, the test vehicle broke the sound barrier after 40 test flights at subsonic speeds.
In February 2022, 4 Su-57 aircraft were delivered to Syria to test the aircraft’s capabilities in combat conditions. In the skies over the province of Latakia, it was planned to study the weapon system, on-board equipment, as well as the degree of detection by enemy aircraft.

Characteristics of the Su-57
The characteristics of the Su-57 can be judged very conditionally, since there is no data on models with updated second-stage engines. It is known that the aircraft has a length of 19.4 m and a wingspan of 14 m. In addition, the sweep angle has been increased compared to its predecessors: 48°.
The empty weight of the aircraft is estimated at 18.5 tons, the maximum take-off weight is 35.5 tons. With 63% fuel (normal load), the aircraft is capable of flying 2,700 km at cruising speed and 1,200 km at supersonic without afterburning. The maximum speed of the Su-57 at altitude reaches Mach 2.45, the maximum without afterburner is Mach 2. The height ceiling is 20 km.
The fighter's main armament
The T-50 is equipped with a 9-A1-4071K aircraft cannon. It is an improved version of the long-known GSh-30-1. The main weapon system consists of a set of air-to-air and air-to-surface guided missiles. They can be placed in internal compartments (this option ensures maximum stealth of the aircraft), as well as on external hardpoints.

The “standard” version of weapons for working against air targets is 8 medium-range RVV-SD missiles and two short-range RVV-MD missiles. Instead of the RVV-SD, it is planned to use the K-77M in the future, capable of hitting highly maneuverable enemy aircraft at a distance of up to 180 kilometers, which will greatly expand the potential of the Su-57 as an interceptor.
To destroy ground targets, up to 8 KAB-500 adjustable bombs or guided missiles with a total weight of up to 4,220 kg, including the latest X-59MK2, can be placed in the internal compartments.
The total weight of the Su-57 combat load reaches 10 tons.
Design
The PAK FA drawing is currently strictly classified. The properties of the new military machine can only be judged from open sources. It is known that the Su-57 belongs to the class of heavy fighters, is multifunctional, has high maneuverability and supersonic cruising speed. Also, the new domestic aircraft is inconspicuous thanks to stealth and electronic warfare technologies.
Cabin
The cabin of the Su-57 is designed for one person, but its space is wider than that of the Su-27 due to the design of the airframe. There is an oxygen generator inside the cabin. The information display system is complemented by displaying information on the pilot's helmet glass.
The cockpit canopy is covered with a radio-absorbing compound. It is reported that now its configuration is not final and will undergo changes during mass production. The digital computer takes into account the pilot’s parameters, including height and weight, optimizing the maneuvers and control of the aircraft for them.
For serial production, the designers promise to develop a new life support system, equipment and oxygen system.
Glider
The PAK FA airframe is made according to a normal aerodynamic design and is of an integral type. The shape of the airframe is largely determined by visibility reduction technologies, which is necessary for a fifth-generation fighter. The weight of the body has been reduced through the use of composites: a quarter of the empty weight of the aircraft and 70% of its surface are composites. In addition, the Su-57 has 4 times fewer parts compared to the Su-27, which reduces the time and complexity of assembling the product.
Do you believe that the Su-57 is the future?1
Not really
Engines
The first samples of the Su-57, its prototype, as well as previous models were equipped with AL-41F1 engines, allowing them to reach supersonic speed without the aid of afterburner. This engine had improved fuel consumption characteristics, a fully digital control system, and increased traction force.
However, in the future it is planned to install a new engine for the Su-57, which is currently called “Product 30”, and in the future will receive the index “AL”. This is a completely new engine, with a new fan, control system and hot end. According to a representative of the developers, this engine has no analogues in the world and is capable of not only improving the flight characteristics of the vehicle, but also reducing its visibility.
Avionics
According to the general director of NIIP, the PAK FA radio-electronic system will be fundamentally different from similar systems in the usual sense. The innovative effect will be achieved thanks to a network of active and passive radio and optical location systems that make up the “smart skin” of the aircraft.
It is planned to install an optical-location system on serial Su-57s, which will effectively detect the enemy both in the front and rear hemispheres relative to the aircraft, protect the vehicle from solar erosion, and also reduce the effective scattering area (RCS), which will reduce the visibility of the aircraft.
A new radar, Belka, is being designed for use on the Su-57, since the previous Irbis model cannot be installed on this aircraft model due to inconsistency with the dimensions. A prototype of this system was first demonstrated in 2009.
Stealth
During the development of the PAK FA, aircraft designers were especially puzzled by technologies for reducing visibility, since this is the main requirement for fifth-generation fighters. This term refers to a set of measures to reduce the likelihood of detecting an aircraft in various wave ranges, including acoustically.
In the Su-57 project, stealth for radio waves is achieved thanks to the shape and coating of the aircraft's airframe, as well as electronic warfare equipment. In particular, the design eliminates the mutual arrangement of surfaces at right angles, which eliminates the effect of a corner reflector.
In addition, some of the weapons are located in the internal compartments of the aircraft to reduce radio signature. For visual camouflage, camouflage coloring of the airframe is used. The first Su-57 had a winter deformation color - this means that the protruding parts of the aircraft were painted in dark spots, and the rest - in a light color, which visually deformed the outline of the aircraft in the visible range.
Thermal and sound signatures have been reduced thanks to the new design of the aircraft's engines. The PAK FA also uses a system of passive sensors that allow it to receive information about enemy positions without giving itself away as signals.
Fighter weapons
The armament of the Su-57 allows the PAK FA fighter to be called a universal fighter, capable of hitting both ground and air targets. The maximum combat load of the Russian fifth-generation fighter is 10 tons. The projectiles are located on 16 suspension points: eight internal and eight external. For air combat, air-to-air missiles can be located in the main weapon compartments:
- up to 6 medium range;
- up to 4 short range.
The following weapons are provided against ground targets:
- up to 4 KAB-500, adjustable bombs;
- up to 4 X-38, high-precision missiles;
- up to 2 X-58, anti-location missiles.
In addition, new types of weapons are being developed for production Su-57s, which will be supplied along with newly produced aircraft for service in the Air Force.
History of the development of the fifth generation fighter T-50 PAK FA (Su-57)
In the 80s of the last century, two aircraft were created in the United States that stood out noticeably against the background of all other military aviation. These were the F-117 and B-2 - very different combat vehicles both in their purpose and in appearance, which were united by only one thing - they were built using technology known as stealth. This word can be translated as “sneaky” or “secretly,” but more often “stealth” aircraft are simply called invisible, since, according to their creators, they are invisible on the screens of radars and heat direction finders. It is clear that this quality can enhance the capabilities of both fighter and strike aircraft.
F-19 is a mythological, never-existing stealth fighter, information about which was actively promoted in the 80s for propaganda or provocative purposes
In those years, the USSR had already begun mass production of the Su-27 and MiG-29, and the next step was to create the so-called MFI - a multifunctional fighter. Stealth in the radar and infrared ranges was one of the main requirements for the new aircraft, at the same time it had to have some other characteristics:
- Capable of long-term flight at supersonic cruising speed;
- Shortened takeoff and mileage;
- Super maneuverability;
- The ability to equally successfully destroy both air, ground and sea targets.
Special requirements were also imposed on the on-board equipment: the radar was supposed to be made much more powerful than that of fourth-generation fighters, and the software system was supposed to have “artificial intelligence,” making the pilot’s work as easy as possible.
The goal was not to build something like the F-117: the customers were more focused on the F-22, which was already being developed then.
When the USSR collapsed in 1991, the “new Russia” inherited two projects for a promising fifth-generation fighter. The first of them is the MiG-1.44 - an aircraft that makes a strong impression even today. The second was a heavier fighter with a forward-swept wing, later known as the S-37 or Su 47 Berkut. At first it seemed that the MiG should become the “Russian stealth” aircraft, since the S-37 was more of an experimental aircraft. Fate, however, decreed otherwise: although Berkut was indeed destined to shine exclusively at air shows, the “1.44 project” completely froze, since its progress was hampered by a chronic lack of funding.
MiG 1.44 - failed “Soviet stealth”
In the meantime, specialists from the Sukhoi Design Bureau were able to organize serial production of the commercially successful Su-30 aircraft, the proceeds from the sale of which made it possible to develop new aircraft models, despite even the deplorable situation in which the Russian aircraft manufacturing complex was located.
The creation of the prototype of the fifth-generation T-50 fighter officially began in 1999. Two years later, the Russian Air Force once again compiled a list of characteristics that the new aircraft should have. Now it has received the preliminary name PAK FA - a promising aviation complex for front-line aviation. Previously, it was planned to build simultaneously a heavy MFI fighter and a cheaper LFS (light front-line aircraft). Now both of these projects were united. It is possible that this decision was influenced by the experience of the United States, where the F-35, which was originally developed as a “cheap addition” to the more powerful F-22, eventually became, on the contrary, prohibitively expensive.
It is also worth noting that a fundamental decision was made to abandon the creation of a special version of the PAK FA with a vertical landing and short take-off - apparently also under the impression of the difficulties faced by American designers.
received an official order for the development of a promising fifth-generation fighter in 2002. In 2004, India began to be involved in this project, having previously purchased Su-30 aircraft and interested in strengthening its air force. It was assumed that mass production of the new machines could begin in 2015, and the total cost of the work would be about five billion dollars.
The first takeoff of the T-50 from the airfield in Komsomolsk-on-Amur
It is noteworthy that Sukhoi JSC was simultaneously engaged in the project of the RRJ passenger aircraft, now known as the Superjet. Nevertheless, priority was still given to military programs, half of which in one way or another related to the future T-50. Flight prototypes of these machines were built in Komsomolsk-on-Amur, and the first run of the promising fighter took place there at the end of 2009.
Flights began in January 2010. First, the T-10M-10 flying laboratory took off, and at the end of the month the T 50 plane took off from the airfield, and after 47 minutes made a successful landing. From this moment on, the “biography” of the Su-57 entered a fundamentally new stage.
Cost of Su-57
Due to the fact that serial deliveries of the PAK FA to the Air Force have not yet begun, the cost of purchasing these aircraft has not yet been disclosed to the general public. What is clear is that the cost of the Su-57 for the Russian army will be significantly lower than for foreign buyers.
Based on the price of its closest analogues, we can say that the price of a domestic innovative fighter will be approximately 120–150 million dollars per unit. Thus, the closest in concept is the fifth generation American F-22, which is supplied at a price of $150 million per aircraft.
Flight tests
The first flaws in the design of the T-50 were identified even before the flights began - during technical runs along the runway. In particular, it was necessary to correct the ground braking system and steering. Fortunately, it wasn't too difficult.
The first stage of the test program included seven flights in Komsomolsk-on-Amur, however, only five were completed - one in January and two each in February and March. In April, two T-50 fighters were loaded onto an An-124 and sent to Zhukovsky, the air force base. At the end of the same month, another test flight took place.

Supersonic speed was achieved for the first time on March 14, 2011. The total number of flights by the end of October 2013 exceeded 450. Moreover, at least one of the experienced fighters was already equipped with a radar station. The state testing program for the aircraft has not been fully completed (completion is scheduled for this year), but back in 2022, the Su-57 was tested in combat conditions in Syria. As is known, aircraft such as the F-35 and F-22 may be in the airspace of this country and in its vicinity, which makes it possible to compare the capabilities of the on-board equipment of the T-50 and American fifth-generation fighters.
Export modification
The version of the Su-57 for delivery to other countries (first of all, deliveries to India were planned) was called FGFA. India, together with the United Aircraft Corporation, sponsored the development of the PAK FA and partially took part in it.
However, in 2022, the Indian side withdrew from the project, explaining that the declared characteristics of the future aircraft do not correspond to the actual ones, and also that many of the systems of the projected aircraft do not correspond to the parameters of the fifth generation. At the moment, the potential importing country of the Su-57 is Peru.
Interesting Facts
At the MAKS-2011 aviation exhibition, during the takeoff run on the PAK FA T-50 , a flash occurred, the pilot quickly reacted and released a braking parachute, the car did not leave the runway and stopped. It was later discovered that it was a fuel system malfunction.
PAK FA T 50
During landing on June 10, 2014, smoke first appeared above the right engine, then a sudden flash and a local fire, the pilot S. Bogdan urgently ejected and remained alive. On December 7, 2015, the restored aircraft continued test flights.
A new thing that was used on the T-50 in the design of the power plant is a plasma ignition system.
The Indian government agreed to purchase the PAK FA from Russian aircraft manufacturers for $100 million.
