Ship systems company Kongsberg is laying off 450 staff as it aims to save money and integrate Rolls-Royce Commercial Marine.

The Norwegian group bought the UK operation in April last year and it has been merged into a new Kongsberg Maritime (KM) division called Commercial Marine (CM).

The company has announced it will make 450 full-time staff redundant across the Kongsberg organisation as part of a plan to save NOK 500m ($54m).
