The United States is one of a number of nations part of the programme (Picture: US Air Force).
An F-35 fighter programme without Turkey is "doomed to a total collapse", the country's president has said.
President Recep Tayyip Erdogan was speaking following warnings by the United States that Turkey's part in the F-35 programme could be jeopardised by its plans to buy the Russian S-400 missile system.
The US says the S-400 could have a negative effect on the F-35 and make its stealth capabilities less effective.
Turkey is due to receive the missile system in July.
Britain's F-35B aircraft will begin their first overseas deployment this year.
The jets will be sent to RAF Akrotiri from RAF Marham.
It was confirmed earlier this year that UK now has nine F-35B Lightning jets ready to be deployed on operations.
Britain plans to eventually have 138 F-35Bs.
