UK defence chiefs have taken on a semiconductor factory in County Durham after fears its closure could leave projects in the lurch.

Defence Secretary John Healey visited the site in Newton Aycliffe, County Durham, today, which the Ministry of Defence has said is the only secure facility with the capability to produce gallium arsenide chips, used in electronic devices.

Reports in August suggested that Italian aerospace company Leonardo was among the previous firm Coherent’s customers, alongside Apple, which had ceased orders with the business and left the plant’s future in doubt.

Coherent, on Aycliffe Business Park, was not thought to have any outstanding orders with Leonardo, according to the newspaper, but its sources suggested the plant may still be needed for future, unspecified programmes.

“Semiconductors are at the forefront of the technology we rely upon today, and will be crucial in securing our military’s capabilities for tomorrow,” Mr Healey said.
