A F-35B Lightning II stealth fighter has touched down in the UK for the first time after crossing the Atlantic.
The aircraft was flown by RAF pilot Squadron Leader Hugh Nichols on the crossing.
It was accompanied by two United States Marine Corps F-35B jets from their training base at Beaufort, South Carolina.
Aviation enthusiasts watched as the planes landed at RAF Fairford in Gloucestershire to a backdrop of double rainbows.
The supersonic jets will fly at the Royal International Air Tattoo and Farnborough International Airshow over the next few weeks.
They are due to enter service with the Royal Navy and the RAF from 2018.
Defence Secretary Michael Fallon said: "The F-35Bs are the most advanced fast jets in the world.
"Whether operating from land or from one of our two new aircraft carriers, they will ensure we have a formidable fighting force.
"They are part of our plan for a stronger and better defence: more ships, more aircraft, more troops available at readiness, better equipment for special forces, more being spent on cyber - to deal with the increased threats to our country."
Air Commodore Harv Smyth, Lightning Force commander, said: "The arrival of Lightning in the UK is an important step towards our delivery of operational capability with the UK's first ever stealth fighter aircraft.
"Operating from land bases or our new aircraft carriers, the F-35B Lightning will provide 'next generation' advanced sensor capabilities which, when combined with its low observable, 'stealthy' design, allow the pilot to see more, know more and act faster than the enemy.
"Our Lightning Force is developing very quickly and we are well prepared for the arrival of our first operational squadron (617 Sqn 'The Dambusters') at RAF Marham in 2018."
