Northrop Grumman will add 100 workers in Rancho Bernardo, Calif., to enable the company to continue developing its Fire Scout unmanned aerial vehicle and a larger version called Fire-X. About 200 employees are already assigned to the program. The company also is negotiating with the Navy to add weapons to Fire Scout, says George Vardoulakis, Northrop's vice president of tactical unmanned systems.
