## Summary

The UK Ministry of Defence, specifically the Royal Navy, has awarded a contract titled "HECLA 5" for a value of £3,500,000. This contract involves the in-service support solution and trials in support of operations, particularly for services related to repair and maintenance. The procurement process is regulated under the Procurement Act 2023, allowing for a direct award to Teledyne Instruments Inc, located in North Falmouth, United States, due to their established expertise and interoperability with the Ministry's existing systems. The procurement method is a direct award, justified by technical reasons, including the need for compatibility with the existing Slocum glider fleet. The contract period began on 10th November 2025 and is initially set to run until 31st March 2026, with possible extensions up to 31st March 2029.

This contract presents significant opportunities for entities within the defence and security maintenance industry, particularly those capable of providing specialised repair and maintenance services for high-tech marine and defence equipment. The contract's focus on interoperability and the integration of data flow systems implies that businesses with technical expertise in these areas could find opportunities for collaboration and sub-contracting. Given the specific technical requirements and the need for integrated systems, larger businesses or those with existing defence sector experience would be more suited to participate in this procurement opportunity.

## Notice

The Royal Navy, part of the UK Ministry of Defence, intends to award a 2 + 2 year contract with a value of PS3,500,000 to Teledyne for the IN-SERVICE SUPPORT SOLUTION AND TRIALS IN SUPPORT OF OPERATIONS (HECLA 5). As a covered procurement, this procurement falls to be regulated under the provisions of the Procurement Act 2023. In the circumstances, the authority may award this public contract directly in accordance with section 41 of the Procurement Act 2023. The applicable direct award justification is that set out in paragraph 7 of Schedule 5 of the Act. This justification applies because the HECLA contract concerns the supply of services by the existing supplier which are intended as an extension to existing services in circumstances where: a change in supplier would result in the contracting authority receiving services that are different from, or incompatible with, the existing services. Namely, a different supplier would lack Teledynes (i) deeply embedded operational expertise and established relationships with strategic partners, and (ii) critical interoperability with strategic partners. And the difference or incompatibility would result in disproportionate technical difficulties in operation and/or maintenance. In particular, the difference in service provided by a different supplier would result in: Incompatibility with existing systems: alternative suppliers would not have access to the proprietary design and technical information required to ensure seamless integration with the existing Slocum glider fleet and associated systems, leading to operational inefficiencies and reduced system performance Disruption to Data Flow: The integration of data from Gliders, profiling floats, and subsequent processing within the MoD's systems would be disrupted, compromising the ability to collect and utilise critical oceanographic data in real time. Loss of Interoperability: The inability to meet interoperability requirements with strategic partners would hinder joint operations and data-sharing capabilities, reducing the effectiveness of collaborative missions. As a result, the services provided by any alternative supplier would be incompatible with the existing Slocum glider fleet and associated systems, leading to disproportionate technical difficulties in operation, maintenance, and mission assurance. Teledyne's unique position as the OEM ensures that the services provided are fully aligned with the MoD's operational requirements, safeguarding the effectiveness and reliability of this critical capability.
