## Summary

The Ministry of Defence in Bristol, United Kingdom, has completed a procurement process to award a contract for the in-service support of several navigation and radar systems across multiple naval platforms, notably the Queen Elizabeth Class. The tender, classified under "Repair and maintenance services of warships," falls within the defence industry category. Northrop Grumman UK Ltd has been awarded the contract through a limited procurement method, specifically negotiated without the publication of a contract notice, due to technical reasons that prevent competition. This supporting contract is worth approximately £204,936,740 and was signed on 1st April 2025; it covers a period of 10 years, providing services from spare parts provision to complex system repairs and additional technical tasks.

This contract presents significant opportunities for businesses within the defence services and military maintenance industries, particularly those with expertise in high-stakes engineering and warfare technology. Although limited in scope for new entrants due to the lack of competition in this particular procurement, businesses capable of providing specialised technical solutions or auxiliary support to Northrop Grumman may find avenues for collaboration. Companies with experience in defence-related contracts, especially those focusing on naval systems, or that possess specialised skills in safety management, technical support, and complex equipment maintenance, will be well-placed to engage in future tenders of this nature within the UK defence sector.
