MOSCOW, December 7. /TASS/. The trials of Russia’s fifth-generation fighter jet Su-57 (PAK FA, the Perspective Aviation Complex of Frontline Aviation) will last several years, President of Russia’s United Aircraft Corporation Yuri Slyusar told TASS on Thursday.

"They [the trials] have just begun. They will, of course, last several years," he said.

The Russian fifth-generation Perspective Aviation Complex of Frontline Aviation (PAK FA, also known as the T-50) fighter jet took to the skies for the first time in 2010. As was reported earlier, the cutting-edge fighter performed its first flight with a new engine on December 5.

Currently, the so-called first stage engine 117S is mounted on the Russian fighter. A new engine has not yet received its name and is conventionally designated as the second stage engine.

It was reported in August that Russia’s T-50 (PAK FA) fifth-generation fighter jet had received the serial index of Su-57. The experimental design work on the most advanced fighter jet should be completed in 2019 and its deliveries to the troops should begin at that time. As United Aircraft Corporation CEO Slyusar said, the pre-production batch will consist of 12 such planes.
