UK's MoD Acquires GaAs Plant to Strengthen Military Supply Chain

MoD

The UK's Ministry of Defence (MoD) has secured the future of a key semiconductor manufacturing facility by acquiring a gallium arsenide (GaAs) plant in Newton Aycliffe, England. The factory, which will now be renamed Octric Semiconductors UK, was purchased from US-based Coherent to prevent its closure, ensuring the UK retains its only secure facility capable of producing GaAs semiconductors vital for military applications, including enhancing fighter jet capabilities.

Coherent, previously known as II-VI, had been seeking to sell the plant as part of its strategy to streamline operations and focus on more profitable ventures, such as silicon carbide wafers and indium phosphide transceivers. However, the MoD's acquisition will not only preserve this critical facility but also boost the UK’s defence industrial capacity and exports.

Investment to Secure Future Defence Technology

The Ministry of Defence plans to invest significantly in Octric Semiconductors UK, with the goal of enhancing the facility's ability to produce advanced GaAs semiconductors for military use. This investment will also pave the way for the development of more powerful chips in the future, strengthening the UK’s defence technology infrastructure.

The plant, originally opened by Fujitsu in 1991, has changed ownership multiple times and has produced III-V-based radio frequency microelectronic and optoelectronic devices for sectors such as communications, aerospace, and defence. Coherent's decision to divest the plant followed a notable decrease in consumer electronics revenue, largely attributed to Apple ending a supply agreement due to design changes in the iPhone.

The UK semiconductor industry has seen several firms close or sell to foreign buyers in recent years, leaving the nation's defence sector increasingly reliant on overseas suppliers. The acquisition of this plant represents a significant step in reversing this trend and bolstering domestic production of crucial military technologies.

"Semiconductors are at the forefront of the technology we rely upon today, and will be crucial in securing our military's capabilities for tomorrow," said Defence Minister John Healey. "This acquisition is a clear signal that our government will back British defence production. We'll protect and grow our UK defence supply chain, supporting northeast jobs, safeguarding crucial tech for our armed forces and boosting our national security."
