Rolls-Royce won a second service contract from the Ministry of Defense to ensure the safety and power performance of Royal Navy nuclear submarines, in a deal worth more than $500 million. Under this contract, the company will continue to operate and maintain the Vulcan Naval Reactor Test Establishment site at Dounreay, Scotland, on behalf of the Ministry of Defense, to service and support Royal Navy programs over the next 13 years. This facility tests the operation and performance of the nuclear power plants used to support the UK submarine flotilla. On November 14, Rolls-Royce announced it had won a contract to provide a total powerplant support package, worth about $150 million over the next three years.
