Emergency F-35 software modification as a last resort

Unauthorised F-35 software changes are considered unlikely in routine service, with an emergency left as a possible exception.

Question

Could Britain force an F-35 software update to integrate UK weapons if normal approval failed?

Short answer

Probably not in routine service, but an emergency with no alternative might lead Britain to use whatever technical access it has.

Notes

Britain is considered unlikely to choose an unauthorised F-35 software modification simply to add national weapons. An emergency with no alternative could change that assessment. Some British technical capacity to modify the system is suggested, but its extent remains uncertain. The proposal is discussed as an exceptional expedient rather than a routine procurement option.
