Rolls-Royce Group is studying locations in the United States and Germany for new engine test sites, a newspaper reported Monday. The company told workers in Derby, England, where it employs 11,000, that it was considering sites outside of the United Kingdom, The Telegraph reported. Derby is the company's "center of excellence" for large engines. It builds and tests the Trent XWB, which will go in the new Airbus A350. That program will continue in Derby as it expands, but the company says it's looking at new locations to help fulfill orders worth about $98 billion. Rolls-Royce could open test sites either in the United States or Germany or both, the Telegraph reported.
