LONG BEACH, Calif. -

California is one of at least a half-dozen states vying for Boeing's attention as the aircraft giant selects a production site for its new 777X jetliner.

Boeing spokesman Doug Alder Jr. said Tuesday that states must submit their bids to Boeing by mid-December. The company began receiving submissions this week.

California officials have been tight-lipped about what incentives they are offering to convince Boeing to build the new planes in the state.

Boeing has been turning out C-17s at its Long Beach plant but production is due to stop in 2015.

Supporters point out that Long Beach has easy rail, port and freeway access and a trained aviation workforce and facility.

The state faces competition from at least seven other states from Washington to Alabama.
