As the National Space Strategy stressed that civil and defence capabilities would be brought together wherever possible (so called ‘dual use’), more needs to be done to identify where overlapping capabilities can be brought together to exploit synergies and remove any unnecessary work and reduce costs. One example of this is considering whether the Skynet system, which is continuing to receive significant public investment, could provide civilian communication services. The Department for Business, Energy and Industrial Strategy and the Ministry of Defence should map out the civil and defence uses and potential uses of other aspects of space and identify areas where existing and emerging capabilities could safely provide joint value. This work should be published no later than the end of February 2023, including an implementation plan of how civil and defence applications will be linked further over the next 5–10 years.
