Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to page 128 of the Strategic Defence Review 2025, what progress he has made on aligning (a) architecture and (b) standards with the (i) defence-wide digital network, (ii) platforms and (iii) services held at above secret.

The Ministry of Defence (MOD) does not comment on the detail of networks operating at Secret or above for reasons of national security. While the Strategic Defence Review 2025 outlines our ambition to align architecture and standards across defence digital capabilities, it would be inappropriate to disclose specific progress or integration details relating to Secret and Above Secret systems, platforms or services.

In terms of standards, Defence Developer Services (D2S) is a containerised platform hosted on MODCloud which can be used to build, test, and deploy applications that can be a mix of own code, open-source and off-the-shelf solutions.
