Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the reasons are for the time taken to upgrade air defence radars at RRH Benbecula and RRH Buchan to the TPS-77 radar standard.

The Type 92 radar has undergone extensive modifications to the signal processing equipment to bring the radar to TPS-77 standard. This complex work required the manufacture and replacement of safety-critical components and extensive testing, whilst also maintaining operational capability, which has necessitated the deployment of an additional radar whilst the Type 92 was being upgraded - all of which has been carefully managed by the Ministry of Defence and delivered to time and within cost.
