Although consideration of the Defence Industrial Policy is outside the remit of this Review, it does have bearing on the affordability and costing debate. The DIS essentially mandates certain industrial strategies to be implemented by the Department in fulfilling its requirements. These have cost implications for the Equipment Programme, in a similar way to capability requirements arising from strategic defence planning dictates. At present, DIS is still relatively recent, but there is likely to be a case for regular review of this strategic framework, potentially synchronised with future SDRs.
