British F-35B aircraft have left the UK to take part in Exercise Red Flag in the United States.
Red Flag, a combat training exercise, will be held in Nevada at the state's test and training ranges with aircraft from other nations.
The Lightning jets from 617 Squadron will first land at Marine Corps Air Station Beaufort in South Carolina, which was their former home before arriving in the UK, before continuing to Nevada's Nellis Air Force Base.
It will be the first time the UK's F-35Bs have taken part in Exercise Red Flag.
RAF Marham's station commander, Group Captain Jim Beck, said: "This is another first for the Lightning Force and will give the opportunity for our pilots to really put the F-35s to the test in a combat representative environment.
"This training is as near to high-end operational flying as our pilots can get in a controlled environment and will really test them and the teams that support the Squadron."
Last year, the aircraft returned to the UK after conducting flight trials with HMS Queen Elizabeth off the east coast of the United States.
In December, a British F-35B made its first launch from UK waters.
