Sukhoi Su-57

The test was reportedly carried out on October 21 near Moscow, but the Russians did not specify whether the new version of the aircraft also used the long-awaited new "Izdeliye 30" engines, which should significantly improve the performance of the Sukhoi 57.

This is not the first time that Russian media sources claim that Su-57s are involved in combat operations over Ukraine

The U.S. should either deliver the F-35 fighter jets that Turkey paid for or return the money or give another product instead, the Turkish foreign minister said Oct. 28.

Ankara will probably respond to a Greek F-35 deployment by purchasing a Russian jet like the Su-57 & the US would like to avoid that from happening

President Tayyip Erdogan said on Friday that Turkey will ensure it is able to buy and produce fighter jets and that Russian Su-35s and Su-57s are a possible alternative to US planes.
He also said that he plans to meet US President Donald Trump next month at the United Nations General Assembly in New York in mid-September.

Russia and Turkey are discussing the possibility of deliveries of the Russian-made Sukhoi Su-57 stealth fighter jet and Su-35 aircraft to Turkey, the RIA news agency cited a Russian official as saying on Wednesday.

President Tayyip Erdogan said on Tuesday that Turkey wants to continue defense industry cooperation with Russia, including on warplanes, following talks in Moscow with his Russian counterpart Vladimir Putin.

Turkish President Recep Tayyip Erdogan and Russian President Vladimir have underscored their close links as they opened a major Russian air show.

Erdogan was Putin's guest of honor on Tuesday at the opening of the MAKS aviation show outside Moscow and even got to peek inside the cockpit of Russia's newest fighter jet, the Su-57, which was unveiled at the show.

Russia was "ready to cooperate" to sell Ankara Su-57 fighter jets if Turkey's participation in the F-35 jet program with the U.S. fell through, the head of the Russian state-owned Rostec Corporation's Sergey Chemezov said on May 2.

The U.S. announced on April 1 that it has suspended "deliveries and activities" related to Turkey's procurement of the F-35 fifth-generation stealth fighter jet over Ankara's plans to buy Russia's S-400 surface-to-air missile system.
