A further five F-35 Lightning jets have landed in their new permanent British home after being flown from the US.
A stunning sunset greeted the Royal Air Force and Royal Navy pilots as they entered UK airspace, flying over South West England on Friday evening following their 4,100-mile (6,600km) journey across the Atlantic Ocean.
The flight from US Marine Corps Air Station Beaufort in South Carolina marked the second wave of the jets arriving at their new base of RAF Marham in Norfolk, which is now home to nine of the supersonic stealth aircraft.
Defence Secretary Gavin Williamson has described the jets, which are estimated to cost between £92million and £120million each, as 'formidable fighters' which are set to keep the country safe from the 'gravest of dangers'.
Britain currently has 15 F-35Bs – the short take-off and vertical landing variant of the jets – and has pledged to purchase 138 in total from Lockheed Martin. The first four F-35s arrived at Marham in early June.Later this year F-35 flight trials will take place off HMS Queen Elizabeth - seeing British pilots fly jointly owned test jets off the deck. The aircraft are being flown by the recently reformed historic 617 'Dambusters' squadron.
The arrival of the five new F-35s is a positive step for the RAF, with the project having had a troubled history of production and delivery - and its cost overruns making it the most world's most expensive weapons system.
It comes as military personnel were warned about the dangers of social media after an RAF airwoman’s Tinder profile was hacked in an apparent espionage plot.
An unknown spy took control of her account and used it to try to manipulate a serviceman into disclosing secrets about the F-35Bs. Operatives with allegiance to either Russia or China are thought to be the most likely culprits.
The F-35 stealth jets have a range of 1,300 miles and carry gatling guns, air-to-air missiles and GPS- and laser-guided bombs. They are behing housed at Marham, which has had a £200million upgrade.
In June, former Rolls-Royce engineer Bryn Jones, 73, was arrested amid fears secret information about the F-35 jets had been passed to Beijing. He was held by Scotland Yard detectives under the Official Secrets Act.
