About 300 jobs at Boeing's Macon plant could be on the line when the company ends production of the C-17 in two years.
Nearly 3,000 employees work on the military cargo plane at the Macon plant and three other locations.
Company spokeswoman Cindy Anderson says they'll start reducing production next year.
They're not certain exactly how many Macon jobs are in danger, because they hope to re-direct those people to other projects.
The Macon plant assembles parts for the C-17 Globemaster III, which is actually built in Long Beach California. That plant is expected to close in 2015.
Last week, the Long Beach plant delivered the last of 223 C-17s produced for the U.S. Air Force. The remaining aircrafts to be built are for overseas customers.
