(Reuters) - Boeing ( BA ) said on Thursday it plans to increase production of its 787 Dreamliner widebody jets to 10 planes per month by 2026.

The planemaker plans to expand its operations at its Charleston County, South Carolina facility with an investment of $1 billion in infrastructure upgrades and the creation of 500 new jobs.

Boeing ( BA ) has been trying to bring 787 production back to a rate of five a month by this year's end, but has wrestled with supply-chain snags that have caused delays.
