The final stages of works are being carried out on the vessel at the GD shipyard in Bath, Maine.

The Zumwalt destroyer is scheduled to undergo the next round of sea trials and is expected to be delivered this year.

Acceptance trials will be performed by the US Navy’s Board of Inspection and Survey onboard, with the navy then assuming ownership of the destroyer.
