Moscow and Ankara are discussing the possibility of deliveries of the Russian-made Sukhoi Su-57 stealth warplane and Su-35 aircraft to Turkey, the RIA news agency cited a Russian official as saying on Wednesday.
Russia began delivering S-400 missile systems to Turkey this year, in a step that strained ties with Ankara's NATO allies and prompted Washington to begin removing Turkey from its program for manufacturing F-35 jets, which Turkey also planned to buy.
The head of Russia's Federal Service of Military-Technical Cooperation said he planned to discuss the S-400 missile defense system with a Turkish colleague as well as "possibly deliveries of the Su-35 or Su-57".
"Much interest has been shown, it's early to talk of contract negotiations, there hasn't been an application yet, consultations have to take place," Dmitry Shugaev, the official, was quoted as saying.
President Recep Tayyip Erdogan said on Tuesday that Turkey wants to continue defense industry cooperation with Russia, including on warplanes, following talks in Moscow with Russian President Vladimir Putin.
Turkey took delivery on Tuesday of a second batch of the S-400 air defense equipment.
"We are taking positive steps in the defense industry sector with the delivery of the S-400 systems starting," Erdogan said at a news conference alongside Putin.
"With that, in our meetings today we had the opportunity to discuss what steps we could take in various fields within the defense industry and what we could do," he added.
The initial delivery of parts of the S-400s arrived in Ankara in July.
While visiting the MAKS air show outside Moscow together on Tuesday, the Turkish leader and Putin called each other "dear friend" and watched Russia's latest jets perform.
Erdogan peeked inside the cockpit of the country's Su-57 and asked if the plane was available for sale to foreign customers.
"Yes, you can buy it," Putin responded with a smile.
