Russia’s New PAK-FA Stealth Fighter and America’s F-22 Share Same Problem

Russia has completed the first phase of government flight-testing for its Sukhoi T-50 PAK-FA fifth-generation fighter. Sukhoi is expected to complete developmental work on an initial operational version of the new stealth fighter in 2019, but the current iteration of the jet will only see a limited production run.

“Today is an historic event – a preliminary conclusion has been signed at the MAKS airshow on the state joint trials of the first stage of the T-50 aircraft prototype,” Russian Aerospace Force commander-in-chief Col. Gen. Viktor Bondarev said last week at the MAKS airshow in Zhukovsky out of Moscow according to the TASS news agency.




“We are now switching to the second stage of trials. Also, we have received a recommendation on beginning the manufacture of the plane’s pre-production batch.”

With research and development work on the airframe expected to be completed in 2019, Sukhoi expects to start to delivering initial production models to the Russian air force that same year.

“In 2019, we should begin the delivery of a pre-production batch of [T-50] planes,” United Aircraft Corporation (UAC) chief Yuri Slyusar told the TASS news agency.

“This is the year when we should complete the R&D work on the PAK FA.”

Slyusar confirmed again that the current iteration of the PAK-FA will be built in limited quantities until development is completed on a new engine.

The stealth fighter is currently powered by interim Saturn AL-41F1 afterburning turbofans producing 32,500lbs thrust each.

“From the very outset, we proceeded from the fact that the final decision had been made on 12 planes,” Slyusar said.

The Russians are continuing to develop the next-generation Saturn izdeliye 30—sometime referred to as the izdeliye 129—engines for the T-50. There are few details available about the izdeliye 30 engines, but the new powerplant is expected to deliver 24,054lbs dry thrust and 39,566lbs of afterburning thrust. The new engine is expected to make its first flight installed onboard the PAK-FA in the fourth quarter of 2017.

For most analysts specializing in the Russian military, the news out of MAKS simply confirms what was already known.
