Defence giant BAE Systems says it is cutting up to 371 UK jobs under plans to slow production of its Typhoon aircraft.
BAE said the vast majority of the job losses would affect its 13,000-strong workforce in Samlesbury, Lancashire, although some roles will also be impacted in its Typhoon final assembly production team.
The group also warned that the move to slow jet production would hit its 2015 financial results and will see Typhoon production sales drop from around £1.3 billion in 2015 to around £1.1 billion in 2016.
BAE said it hopes to look at opportunities elsewhere in the business to mitigate compulsory redundancies.
The blow comes as BAE is having to stretch out its Typhoon production line.BAE secured a deal to supply 28 Typhoon aircraft for the Kuwait Air Force in September, with deliveries from the Italian Typhoon final assembly line set to start around the end of the decade.
The group is also in talks with Saudi Arabia to try to secure further Typhoon purchases, but discussions are making slow progress.
