Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether there have been any incidents of green glow in the helmets worn by F35B pilots; whether that green glow has impeded pilots' efforts to read instruments; how many incidents of total failure of night vision capability have been experienced; and if he will make a statement.

The green glow is a known and recorded issue for the F-35 helmet display; a resolution is being developed. The UK is not aware of green glow impeding the pilot's ability to read the aircraft's instruments, nor has it experienced a total failure of night vision capability. UK pilots have found the Gen III helmet to offer outstanding capabilities across the range of F-35 operating roles.
