In 2015, Russia slowed PAK FA (T-50) production and reduce its initial order to 12 jets due to the nation's deteriorating economy, along with the manufacturer's ability to produce the more complex aircraft.
Russian Air Force Commander-in-Chief Viktor Bondarev, stated that the PAK FA is to enter serial production in 2017, after all trials are complete. Due to the aircraft's complexity and rising costs, the Russian Air Force will retain large fleets of fourth-generation Sukhoi Su-27 and Su-35S fighters.
