Orbital Sciences Corporation, a manufacturer of space vehicles for commercial, military, and civil government entities, will expand its launch vehicle production facilities in Chandler, Arizona. Company officials say they plan to build an 82,000-square-foot office building adjacent to its current manufacturing facility that will have space for 330 workers, some of whom will be moved from current sites in the area. The expansion will ultimately bring the Virginia-headquartered company's facilities in Chandler to 232,000 square feet with capacity for 2,200 employees, nearly double the current work force. The Arizona Republic reports that the first building will house mechanical, electrical, software, and system engineers, along with program managers, with salaries expected to be a minimum of $70,000 per year. Construction is scheduled to begin later this month, with occupancy planned for sometime in late 2009. No information was released regarding financial investment or incentives.
