New Ninth Example of Russian 5th Generation Sukhoi Su–57 (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.
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.
