Question to the Ministry of Defence:

To ask Her Majesty's Government whether personnel in squadrons of F35B combat aircraft embarked in the carriers will be working to the same harmony rules.

Jointly manned UK Lightning air squadrons will operate to the same harmony guidelines. The overall principle is that we will manage all embarked UK air squadrons - which will include Fixed and Rotary Wing forces and personnel from all three Services - to ensure that the different harmony guidelines which the Services routinely apply, do not adversely affect operational output.
