BATH — The future USS Zumwalt is moving closer to delivery to the U.S. Navy.

The Navy announced Thursday that the 610-foot destroyer had returned to Bath Iron Works after two days of at-sea acceptance trials aimed at conducting final evaluations before the Navy takes delivery.

A spokesman for the Naval Sea Systems Commander said systems were demonstrated for the Navy’s Board of Inspection and Survey, which will determine whether Navy test objectives were met. Any corrective measures would have to take place before delivery to the Navy.

The Zumwalt is the first of three destroyers featuring an angular shape aimed at making them difficult to see on radar. It’s due to be commissioned in October.
