Question to the Ministry of Defence:

To ask His Majesty's Government how many Typhoon aircraft were in service with the Royal Air Force at the end of 2022; how many were at readiness for use; and how many were in deep maintenance or mothballed.

The number of aircraft in the Typhoon fleet as at 31 December 2022 broken down between the Forward and Sustainment Fleets is given below:

The Forward Fleet comprises serviceable and short-term unserviceable aircraft. Typically, the short-term unserviceable fleet aircraft are undergoing minor works, forward maintenance or other unforeseen rectification or technical inspection that can arise on a day-to-day basis. The sustainment fleet includes aircraft airframes undergoing upgrade or maintenance or being held in storage. The number of aircraft varies day-to-day, according to normal flight management activities.
