Tender Notice
Summary of the contracting process

The Ministry of Defence (MoD), located in Bristol, England, is currently in the stage of amending a tender process titled "700910368- MDMSS - VTN". This involves a voluntary transparency notice to extend a contract with Thales UK Ltd for the Multi Domain Mission Support System (MD MSS). The procurement falls under the service category "Development of software for military applications" (CPV code 72231000) and is classified as a single-source contract, which is justified under specific exclusions from the Defence and Security Public Contracts Regulations. The contract is valued at £32,000,000 GBP, with a planned period running from 1st April 2026 to 31st March 2028. Deliverables are expected across multiple regions, including the United Kingdom, British Overseas Territories, and other parts of Europe. The amendment to this single tender action was published on 28th November 2025, with prior tender closure on 26th May 2025.

This tender offers significant opportunities for industry players with a strong background in military software applications, particularly those experienced with multi-domain mission systems. Although the contract is a single-source procurement, the collaboration emphasises the necessity for technical proficiency in managing defence and aeronautical information systems. Businesses with expertise in robust and secure information management systems would find this arrangement aligned with their capabilities. However, the procurement is not suitable for SMEs or VCSEs, indicating the need for well-established enterprises with the technical skills and resources required to support complex defence contracts.
