BAE Systems will make 3,800 staff redundant as a result of the recent merger between British Aerospace and GEC Marconi.
The company said eliminating overlaps between the companies’ operations was behind the move.
Avionics sites at York, Ilford and Blackburn will close, with the remainder of the losses being dispersed across other sites.
BAE’s Royal Ordnance site in Nottingham is also under review, with a further 390 jobs at risk.
The company said it hoped to achieve the majority of the cuts through voluntary redundancy programmes, early retirement and releasing sub-contracted workers.
John Weston, chief executive of BAESystems, added that some jobs also depended on forthcoming contract decisions, in particular for the Hawk jet trainer and a Ministry of Defence roll-on, roll-off ferry contract.
The company confirmed it is going ahead with plans to recruit 2,000 new engineers, mainly in software and systems, over the next two years.
It also said that a further 1,000 young people, including graduates, would be joining the company over the same period.
