Key facts
- Current Portsmouth context
- An Airbus page published 24 November 2025 says satellite digital processors and payloads are developed and incorporated in Portsmouth.
- Historical Neptune cleanroom
- A UK Space Facilities page dated 15 March 2018 identified Neptune as the Portsmouth site's principal space-integration cleanroom for spacecraft sub-systems, payload modules and instruments.
- Historical external-use wording
- The 2018 directory said sections of Neptune and smaller cleanrooms could be used by external companies subject to availability and normal commercial arrangements. This does not establish current access.
