Although the suspension call was for all United States F-35 aircraft worldwide to be grounded, that call apparently does not extend to aircraft in other countries. The British Ministry of Defence posted on its Twitter account that the U.K. version of the aircraft is not grounded, though they have temporarily paused flights of some units pending their own inspection.
There are three variants of the F-35: the F-35A, F-35B, and F-35C. The F-35A is a conventional aircraft that utilizes standard land-based runways. The F-35B is a short takeoff and landing aircraft, made to be used in conjunction with smaller Marine Corps amphibious watercraft, and the F-35C is a variant designed to take off and land on aircraft carriers. The only variant that has not yet been approved for combat operations is the F-35C, and it should be approved for United States Navy use in February 2019. The aircraft that crashed in September was an F-35B, but it's thought that the fuel tube defect extends across all three variants, rather than being specifically related to the jet with short takeoff and landing capability.
