Rolls-Royce is cutting 2,600 jobs in a restructuring programme, and warned that more posts will be shed.
The streamlining will mainly involve the aerospace division, which has a plant at Inchinnan in Renfrewshire, but a spokesperson said jobs will not be lost in Scotland.
The engineering group yesterday refused to disclose where the cuts would be within its 55,200 global workforce.
Rolls-Royce employs 24,800 people in the UK.
Most of the jobs will go over the next 18 months in the drive to improve operational efficiency and reduce costs.
The cuts will be on the Trent 1000 and XWB engine programmes, which have moved from engineering to production stages.
A reorganisation of Aerospace and Land & Sea divisions will also allow a reduction in management and structural costs including indirect labour.
New facilities in the USA and at Rotherham and Washington in the UK set new standards in productivity and efficiency, the company said.
The restructuring will cost around £120 million over the next two years but will produce annual savings of around £80m.
The reductions will be sought on a voluntary basis where possible, but necessary skills will be retained.
Chief executive John Rishton insisted the company is well positioned in growth markets.
David Smith has been appointed Rolls-Royce’s new chief financial officer, replacing Mark Morris.
Mr Smith joined from Ford and is currently the aerospace finance chief.
