## Summary

The Defence Science and Technology Laboratory, a central government public authority in the United Kingdom, has awarded a follow-on contract to L3 Harris ASV for the storage, maintenance, and repair of Authority-owned surface vessels under the title "Surface Assets Storage and Maintenance." This direct award is part of a completed tender process initiated on the basis of technical specialisation and intellectual property considerations. The contract, valued at £1,162,350 gross, with £968,625 net, covers services classified under dry-docking, reconditioning, and upgrading of ships. Located in Salisbury, with services delivered across the UK, the contract commenced on 17 December 2025 and is set to continue until 31 March 2026, with options for extension through to 2029.

This procurement offers significant opportunities for businesses involved in maritime technology and maintenance, particularly those capable of handling complex Unmanned Surface Vehicle (USV) systems. Companies with expertise in system integration, third-party software integration, and compliance with maritime safety codes will find this contract appealing. L3 Harris ASV's unique capabilities and access to proprietary systems make them an ideal partner, but similar businesses equipped with the required technical proficiency and intellectual property knowledge could also benefit from exploring partnerships or sub-contracting opportunities in future tenders.

## Notice

The Authority has awarded a follow-on contract to L3 Harris, to provide storage, maintenance and repair services for a number of Authority owned surface vessels.

### Procurement Information

Continuation of technically specialist services, IP issues and timescales. This is a follow-on contract for the Storage, Maintenance, Operation and Repair of the Maritime Autonomy Surface Testbed (MAST) assets. Service provision is required immediately. MAST assets are complex system-of-systems that provide an Unmanned Surface Vehicle (USV) system capability. L3 Harris has unique SQEP specific to the Dstl-owned systems (which incorporate L3Harris and Dstl owned IP). They have a detailed knowledge of the system and can fulfil the role of 'Design Authority' to safely design vessel modifications for trial requirements (including integration of Third Party software, sensors and payloads), can safely operate the USV and ensure compliance with legislation, primarily the Maritime and Coastguard Agency Workboat Code, and the Ministry of Defence Certification requirements. The MAST is a complex system of systems, which is software intensive. The software architecture includes software elements, with IP owned by Dstl and by L3Harris ASV distributed inextricably throughout. The expertise required to develop and integrate systems is the USP of L3 Harris and no other 3rd party would be able to get access to this due to the systems proprietary nature. The Dstl owned software cannot function without the OEM software. Given the complex technical nature of the MAST systems and the IPR issues, any alternative supplier would introduce an unacceptable level of technical and project management risk to this procurement.
