WASHINGTON—The Trump administration formally ejected Turkey from the American-led F-35 Joint Strike Fighter program over Ankara’s decision to purchase a Russian air-defense system, prompting a protest from Turkish officials. Pentagon officials on Wednesday said Turkey’s purchase of the Russian S-400 air-defense system was incompatible with participation in the F-35 program and declared an end to Ankara’s involvement.
