Solid State plc (AIM: SOLI), the specialist value added component supplier and design-in manufacturer of computing, power, and communications products, announces its manufacturing subsidiary, Steatite, has been awarded a £1.65 million contract by The Defence Science and Technology Laboratory (DSTL), an executive agency of the Ministry of Defence (MOD) of the United Kingdom, to design, develop, qualify, and supply complex integrated systems. This significant programme will be delivered from Steatite's newly established integrated systems facility, reinforcing the Company's commitment to supporting the UK's defence capabilities with sovereign designed and manufactured innovative, high-quality engineered solutions.

Under the contract, Steatite will produce a series of rugged 31U, large cabinet enclosures, each integrating seven precision-engineered Line Replaceable Units (LRUs) together with a standalone Human Computer Interface (HCI). These systems will be designed to MOD specifications and built in accordance with relevant defence standards. The systems will undergo rigorous EMC, temperature, and vibration testing, to ensure resilience in demanding defence environments.

Key elements of the project include:

·      Five custom designed electronic LRUs per cabinet, featuring bespoke mechanical layouts and wiring assemblies.

·      A dual-mode cooling solution capable of operating in both air-cooled and chilled-water configurations to support deployment across varied operational environments.

This contract win highlights the strategic importance of Steatite's purpose-built integrated systems facility and demonstrates the Company's ability to deliver mission-critical systems that combine engineering excellence, reliability, and resilience.

The majority of the contract is expected to be delivered in the current and following financial year.

Matthew Richards, Divisional MD at Steatite said: "We are proud of our new facility established to provide the MOD with resilient, mission-critical systems that deliver exceptional performance, quality, and reliability - both for this project and for future programmes."
