New Photos of Russia’s Sukhoi Su-57 Stealth Jet Show Some Progress of Russian Advanced Fighter Program

New Ninth Example of Russian 5th Generation Sukhoi Su57 (PAK FA) With Its Enormous Fuel Tanks Spotted at Zhukovsky.

Vladimir Zinenko, admin for the Facebook group page “ВВС России”, a page for fans of the Russian Air Forces, has shared new photos of the ninth example of Sukhoi’s 5th generation fighter, the recently designated Su-57. The aircraft has been referred to in development as the T-50 and is the outcome of Russia’s PAK-FA advanced fighter development program. The program is intended to field an advanced 5th gen air superiority aircraft to offer capabilities similar to the U.S. F-22 Raptor.

One noteworthy distinction between the U.S. Air Force’s F-22 Raptor and the T-50/Su-57 is advanced, precision air-to-ground capability engineered into the aircraft from its origin, whereas the F-22 Raptor acquired this capability following its “increment 2” upgrade program in 2005 and has since demonstrated its precision strike capability in Syria.

The new aircraft flew through Zhukovsky International Airport two days ago when a number of spotters photographed it. The photos quickly appeared on the Russian aircraft spotter and photographer forum RussianPlanes.net.

The T-50 prototypes have worn several paint schemes so far and this latest example is wearing the pixelated two-tone camouflage livery seen on at least one other T-50/Su-57.

For the long ferry flight made from where the aircraft apparently first flew on Aug. 6, 2017 at Komsomolsk-on-Amur it transited approximately 3,273 miles (6,066 kilometers) to Zhukovsky where the photos were taken two days ago. The aircraft carried a large pair of underwing tanks during the flight.

The long ferry flight from its likely production facility to the Moscow area for testing spanned most of Russia.

This new aircraft, wearing tail number “511”, has been characterized as a production test aircraft using the final version of the Su-57’s airframe. It is said to have tested production capabilities for follow-on examples likely to be built in a low-initial-rate setting.

Questions continue to surround the Su-57 program. Criticism has surfaced in western media of the aircraft’s actual stealth capability, but many of these criticisms in popular media mirror those seen in the western non-defense press about the U.S. F-35 program, a largely successful program that has nonetheless drawn intense scrutiny and criticism in media outside the defense industry.

The majority of concerns about the Su-57 are focused on its engine program. The aircraft have used the NPO Saturn/Izdeliye 117, or AL-41F1 engine with vectored thrust capability. An engine fire in June 2014 seriously damaged the fifth PAK-FA/T-50 prototype during testing. That aircraft has since been repaired following engine replacement that took over a year. There have been reports of a program to re-engine the aircraft by 2025 with an entirely new powerplant intended specifically for the Su-57.

Russian next generation stealth fighter to fall victim to the Russian financial crisis?

PAK-FA may suffer significant cuts.

Russian Deputy Minister of Defence Yuri Borisov, has recently announced that the PAK-FA programme may be halted or adjusted, due to the dire conditions of Russia’s economy, affected by the Ukrainian crisis and the subsequent (proxy war and) EU sanctions.

Initially, the Russian Air Force was expected to procure more than 150 PAK-FA next generation stealth fighter jets, with the first examples to be delivered to the active squadrons in 2016. In December 2014, the RuAF plans was to receive the first 55 fighters by 2020.

However, as announced by Russia’s MoD last month, the production will be slowed down and the initial order cut to 12 jets: the nation’s economy has deteriorated and the aircraft troubled development and increasing costs have persuaded the Russian Air Force to retain their large fleets of fourth-generation Sukhoi Su-27SM and Su-35S to obviate to the reduced amount of frontline next generation fighter jets.

Indeed, the PAK-FA program seems to be quite costly, because of the troublesome childhood of the new Russian fighter and the problems associated with the fighter’s powerplant.

According to the Polish media outlet Altair, the production is to be started next year, and the Russian Air Force would stop the production after the first 12 examples are acquired for a period of operational tests. This would serve two purposes: first of all, it would enable the Russian MoD to plan the procurement of Su-30SM and Su-35 jet fighters to eventually save some money. Secondly, that period would be used to test the PAK-FA’s operational capabilities, and possibly to get rid of any of the problems that could emerge during the initial field operations.

Sukhoi planned to sell some 400 fighters to the Russian and the Indian Air Force; figures that seems to be well above the current sales forecast: India has considerably reduced the requirement from 200 to no more than 130-145 jets, and has recently expressed concerns over the raising costs, delays and technical issues that have plagued the 10.5 billion USD FGFA (Fifth Generation Fighter Aircraft), that is based on the PAK-FA aircraft.

Russians have started working on a new engine for their 5th generation stealth fighter

The Russians have started the test and design works, aim of which is to provide the Russian 5th Generation fighter with a relevant power-plant.

If there is one field in which the Russians seem to fall behind in aircraft development – it is definitely the propulsion systems for the new jets.

Currently, prototypes of the Sukhoi T-50 PAK-FA (Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii—Future Tactical Air System) which is the Russian 5th Generation fighter design, use the Saturn AL-41F1 engines, which are a series production model used by the Russian 4.5 generation fighters, such as Sukhoi Su-35.

We must remember that childhood of T-50 PAK-FA has been quite troublesome and engines have already been cause of some quite embarrassing incidents in the near past.

The current engine should not be mistaken with the NPO Saturn AL-41F engine, which has been designed for the Multi-Role Frontline Fighter, also known as MiG-1.44. The engine used by the PAK-FA prototypes is actually an updated variant of the AL-31F power-plant.

According to altair.com.pl, NPO Saturn corporation representatives recently announced that the prototype of the second engine is expected to be ready for flight testing in 2015. The new engine, shall be ready for the series production by 2020, with the first prototype being completed by 2016, and flight tests planned to happen in 2017.

At least such statements were made during the Aero India 2015 expo by Vladislav Masalov, who is the chief of the ODK company working on the jet propulsion systems.

In the meanwhile, numerous media outlets report that Russia and India are going to sign a contract, regarding the future development of a 5th Generation Fighter in 2015. According to IHS Jane’s, Yuri Slyusar, who is the CEO of the United Aircraft Corporation (UAC), stated that the parties are at the final stage of negotiations. The preliminary agreement has already been signed. The program is to involve the UAC company on the side of Russia and the Hindustan Aeronautics Limited company for India. Slyusar confirmed the fact that the new generation engine testing program is under way.

It is yet unclear, when we may expect the PAK-FA or the Indian fused design to be introduced into service in the front-line units though.

Russia’s fifth generation PAK-FA prototype catches fire on landing

Russian T-50 fighter plane damaged on the ground.

On Jun. 10, Russia’s 5th generation stealth fighter plane Sukhoi T-50 (PAK FA – Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii—Future Tactical Air System) which since February has been a subject of state test programme in Zhukovski, caught fire on landing.

The landing was succesful and Sergey Bogdan, the Russian test pilot who flew the T-50 during the test flight, was unharmed. Sukhoi officials claim that the fire was local, and was quickly extinguished. The fighter is to be repaired.

Two remaining examples of T-50 are undergoing ground tests and static tests. According to the official stance of the Sukhoi company, the incident will not have an impact on the test program, and the proceedings are to be continued in accordance with the planned schedule.
