Announcing the agreement at a press conference in the Turkish capital, Sir Keir called it “a landmark moment”.
The provision of 20 Typhoon fighter jets will “bolster security across Nato, deepen our bilateral defence cooperation and boost economic growth” in both the UK and Turkey, he said.
“I’m proud that British Typhoons will form a vital part of the Turkish airforce for many years to come, as you defend Nato’s south-eastern flank for the good of all of us,” he added.
The Eurofighter jets are jointly produced by Britain, Germany, Italy and Spain, and the deal was subject to approval from the other members of the consortium.
About 37% of each jet’s production takes place in the UK, including final assembly at BAE Systems plants in Warton and Samlesbury in Lancashire.
The government said the deal would support 6,000 jobs at the two BAE plants, 1,100 in south-west England, including at the Rolls-Royce plant in Bristol, and 800 in Scotland.
