WASHINGTON (Reuters) – Four U.S. senators on Thursday introduced a bipartisan bill to prohibit the transfer of F-35 fighter aircraft to Turkey until the U.S. government certifies that Ankara will not take delivery of a Russian S-400 air defense system, a statement on the move said.
Turkey is a production partner in the trillion-dollar F-35 fighter jet program but Ankara also wants to purchase a Russian missile defense system, which the United States says would compromise the security of F-35 aircraft, which are made by Lockheed Martin Corp..
The senators – Democrats Jeanne Shaheen and Chris Van Hollen and Republicans James Lankford and Thom Tillis – have all expressed alarm over Turkey’s planned purchase of Russian S-400 missiles and said the NATO ally cannot have both.
“The prospect of Russia having access to U.S. aircraft and technology in a NATO country, Turkey, is a serious national and global security risk,” Shaheen said.
