About

The Ministry of Defence (MOD), through the National Armaments Director Group (NADG) and UK Space Command, is seeking suppliers for Project NOCTIS-2 to enhance the UK’s Space Domain Awareness by procuring, installing and supporting ground-based space surveillance sensors, including optical systems and associated infrastructure. The Authority is formally engaging industry via a UK4 Notice on the Defence Sourcing Portal; the project is expected to follow a phased acquisition approach potentially covering equipment design and construction, sensor installation, and operation and through-life support. Participation is limited to organisations with a registered UK legal entity (parent companies outside the UK may participate subject to Authority agreement with activity conducted through the UK entity), and all off-site data processing and storage must be conducted within the United Kingdom. Sensors and their housing or infrastructure are to be procured as an integrated solution, the Cyber Risk Profile for the procurement is Level 2, and the anticipated contract period is three years from 2027 to 2030 with options (1+1) subject to approvals; an Industry Day was held on 27 March 2026 and presentation slides are at Annex A of the PSQ on the Defence Sourcing Portal.
