The group is consulting globally with appropriate employee representatives on the UK and Singapore investments.

Rolls-Royce plans to invest in four new factories and two advanced research programmes in the UK. These investments will enable Rolls-Royce to respond to anticipated growth in its aerospace and civil nuclear markets and will create or secure over 800 jobs in innovative high-value manufacturing programmes, largely in Assisted Areas.

The research programmes will focus on critical technologies to reduce the CO2 emissions of future aircraft programmes and will accelerate the development of new manufacturing methods that create significant competitive advantage for the UK.

Rolls-Royce is also separately announcing the development of a new wide chord fan blade factory in Singapore.

Sir John Rose, Rolls-Royce chief executive, commented: “These are significant investments in capability and research which reflect our commitment to continue to invest in the future of our business, even at this stage in the economic cycle. We are delighted that the British Government will be supporting these projects.”
