A company spokesperson said: “The Covid-19 pandemic has created a historic shock in civil aviation that will take several years to recover.
“The demand for our civil aerospace products and services has declined dramatically and we have had to make some difficult, but necessary, decisions to position ourselves for the future.

“We are currently consulting with unions and employee representatives, and will be looking at all mitigation options, including offering to transfer our staff to Derby.
