The Fleet Support Plant, manufacturing aerospace components, is expected to be fully operational in 2018.
The investment is part of Rolls-Royce’s ongoing industrial transformation and marks the final stage of the modernisation programme for disc manufacturing in the region.
Mike Mosley, Rolls-Royce, chief operating officer – supply chain, said: “Rolls-Royce is focused on transforming our global industrial base to develop solutions that our customers can trust.
“Our further investment in Washington demonstrates our continued commitment to developing innovative technology and lean facilities, which will improve performance and drive profitability for our business.”
David Ayton, Rolls-Royce, executive vice president for the rotatives supply chain unit, added: “Our exceptional people engineer and make extraordinary components.
“This showcase facility gives us the opportunity to set new standards of excellence for quality, delivery and cost.”
The new 8,000m2 facility will have the capacity to manufacture over 1,500 fan and turbine discs a year for use in a wide-range of engines.
Staff from the existing Sunderland facility will start to move into the new site from 2017 and the Sunderland site is scheduled for closure in 2019.
Cllr Paul Watson, leader of Sunderland City Council, told BQ: “We’re delighted that Rolls-Royce, which is already using some of the most advanced manufacturing techniques to create world-class products in Sunderland, is investing £30m to build a new plant in the city.
"Sunderland has a long and proud manufacturing history, and enterprising companies such as Rolls-Royce recognise the advantages its skilled workforce, business support and accessible location offer.
"Rolls-Royce’s news is a resounding vote of confidence in Sunderland as a great place to do business.”
