The U.K. Government says millions of pounds will be invested into the economy of North Wales, following an announcement that Sealand, in Flintshire, has been chosen as the location for the F-35 fighter jet repair hub.
The Welsh Secretary Alun Cairns says the move will support hundreds of jobs.
Over the lifetime of the programme, hundreds of European-based F-35 aircraft will be serviced and maintained in North Wales.
This work will generate hundreds of millions of pounds of revenue for the UK defence industry, with the potential to unlock more than £2 billion of future F-35 support revenue over the lifetime of the programme, according to the MOD.
It says this will help sustain thousands of high tech jobs and skills.
The work will involve maintenance and repair of systems for the F-35 aircraft including electronic and electrical components, fuel, mechanical and hydraulic systems, and ejection seats.
The new global avionic and aircraft component repair service is expected to be operational from early 2018.
