"I am delighted to confirm that we are doubling the size of our F-35 force into a formidable fleet of 35 stealth fighters. This is another massive order in the biggest defence program in history," the official said.
According to the defence secretary, this program is "set to bring an immense boost of £35 billion into the British economy", and it will be "welcome news to the UK firms that many more jets are now set for production."
The UK is not the only Western state that decided to increase its number of F-35 fighters. Last month, Belgian Prime Minister Charles Michel officially announced that the state opted for US F-35 Lightning II to re-equip its Air Force Brussels, and planned to purchase 34 US fighter jets.
