WASHINGTON (AP) _ The Federal Aviation Administration awarded Lockheed Martin a four-year, $350 million contract Thursday to assist in modernization of the nation's air traffic control system.

The award calls for Lockheed Martin to provide engineering, planning, automation, environmental analysis and other services to the FAA as it implements a new control system. The company will provide more than 1,000 workers to FAA headquarters, regional centers and field facilities.

In addition to the initial four-year term, the contract has options for three two-year extensions.

FAA Administrator Jane F. Garvey said the contract ``is critical to making the FAA's 30,000-plus facilities more reliable and expanding the system's capacity to meet the growing demand for aviation services.''
