"Thank you to those in the area for your cooperation."

RAF Marham is the home of the F-35 Lightning, the RAF's multi-role stealth fighter which can also operate from the Royal Navy's aircraft carriers HMS Queen Elizabeth and HMS Prince of Wales. 

The base contains a workforce of 3,600 service personnel, civil servants and contractors who carry out a range of engineering support functions from maintenance to frontline support.
