## Summary

The Ministry of Defence (MoD) has awarded a contract for the in service support of air particle detectors to Spectral Laboratories Incorporated (SLI), marking the completion of the procurement stage. The procurement, classified under the industry category of "Electronic and electrical spare parts for military vehicles," involves a five-year contract with potential extension options up to an additional five years. Geographically, the contract covers a wide scope, including the UK, British Overseas Territories, the Channel Islands, Isle of Man, and further afield in Europe and the rest of the world. The contract, which began on 1st November 2025, will continue until 1st November 2030. The procurement method used was a limited, negotiated procedure without prior publication, suitable for above-threshold contracts. The total contract value is GBP 2,177,123.

This contract offers substantial growth opportunities for businesses involved in the defence sector, particularly those specialising in the supply of electronic and electrical spare parts for military vehicles. SMEs stand to benefit from this contract due to its specific suitability for small to medium-sized enterprises, as indicated by the tender documentation. Though the award has been made to SLI as the Original Equipment Manufacturer, the significant duration and potential for extension hint at future opportunities for other vendors who can provide innovative products or support services in this sector. Businesses wishing to engage or expand within the military defence supply chain in diverse geographical regions may find this contract as both a significant reference and a gateway to further opportunities.
