The revolutionary plane has only been in service with the RAF since 2012 but now a Pentagon briefing has been told that all F-35s will need improvements.
A special hearing convened by the House Armed Services Committee was told that the American Pratt & Whitney F135 engines used in all F-35 variants have been "under specification" since the beginning of the project.
The Royal Navy and the RAF operate the F-35B aircraft, mainly from the new Queen Elizabeth-class carriers, and often in a joint capacity with US Marine Corps' own F-35B.
The "under-speccing" of the engines is not a safety issue but does mean that expensive overhauls will need to take place earlier than the Ministry of Defence expected.
