Rolls-Royce is planning to open a plant in Prince George County.
The world's second largest maker of aircraft engines says plant about 25 miles south of Richmond is expected to create about 500 jobs and be fully operational by the end of 2009.
Rolls-Royce says it will test and assemble engines for midsize jets at the new plant. The plant also will have the capability to create rotors for the F136 engine for the Joint Strike Fighter.
The London company has its North American headquarters in Chantilly. It had announced plans this month to close its turbine plant in Liverpool, England.
Governor Timothy M. Kaine was to formally announce the economic development at a Capitol news conference Tuesday.
