## Summary

The procurement process titled "In-Service Support of Platform Data Management Systems" is managed by Defence Equipment and Support, a central government public authority in the United Kingdom. This procurement is set within the defence and security industry category and involves services related to navigation equipment. The location of the contracting authority is MOD Abbey Wood, Bristol. Currently, the process is at the award stage, with the award date noted as 14th November 2025. The contract aims to commence in July 2027 and has a planned duration of 8.5 years, with potential extensions. The procurement method utilised is a direct award under the provisions of the Procurement Act 2023, acknowledging Ultra Sonar Systems Ltd as the sole supplier capable of fulfilling the contract requirements due to technical and IP constraints.

This tender offers significant opportunities for businesses engaged in technical services, especially those with expertise in navigation systems maintenance and support.

Additionally, the focus on sustainability and social value in procurement aligns with broader government priorities, indicating a scope for businesses that deliver innovative, environmentally-conscious solutions.
