The entire Long Beach plant is expected to close by the end of next year unless there's a sudden influx of new orders.
"Our rich history of aerospace manufacturing makes this an emotional day for Long Beach, as the C-17 plant is the last of what was previously a robust aerospace manufacturing industry in California," Long Beach Mayor Bob Foster said in a statement. "The impacts from these reductions will affect the State and the region, and is not constrained only to Long Beach."
