Russia and Turkey will jointly produce the next generation S-500 aerial missile defense system, Turkish President Recep Tayyip Erdogan said on Saturday.
The United States, a military ally in the NATO alliance, has threatened sanctions against any country that purchases Russian defense systems. Turkish-US relations became strained after Turkey pushed forward with the purchase of Russia's S-400 missile defense system.
"There is absolutely no question of (Turkey) taking a step back from the S-400s purchase. That is a done deal," Erdogan said. "There will be joint production of the S-500 after the S-400."
Last month, the US halted deliveries of F-35-related equipment over Turkey's refusal to back down from the S-400 deal with Russia.
The US "are passing the ball around in the midfield now, showing some reluctance," Erdogan said on Saturday. "But sooner or later, we will receive the F-35s. (The US) not delivering them is not an option."
