Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the Department of Energy and Climate Change Aviation Plan Update (2015), what role his Department is taking in the trials of the Lockhead Martin TPS-77 radar system; and how he will ensure his Department's interests are properly taken into account.

Although the trialling of the TPS-77 radars, mentioned in the 'Aviation Plan: 2015 update', is not a specific work stream, the Ministry of Defence will lead the flight trials activity, with assistance from defence contractors as appropriate. This will ensure that the Department's interests are properly taken into account.
