Question to the Ministry of Defence:

To ask the Secretary of State for Defence, for each Typhoon aircraft with a clearly defined out of service date, what is the (a) tail number, (b) expected end of service date and (c) expected remaining airframe fatigue life at end of service of each aircraft.

Routine Fleet Management processes take account of periods of surge in airframe use to meet Defence Priorities, ensuring an even distribution of the fatigue life of airframes throughout the life of the Fleet.

While remaining aircraft fatigue life across the whole fleet is considered as an important factor when calculating Out-of-Service dates, other factors including obsolescence, upgrade programmes and changes in the nature of the threat.
