BATH, Maine (AP)   The second stealthy destroyer being built for the U.S. Navy has cut short its first sea trials after an equipment failure.

The Navy says the problem happened Tuesday, a day after the future USS Michael Monsoor left Bath Iron Works.

A spokeswoman for the Naval Sea Systems Command says the equipment failure during builder trials prevented workers from testing propulsion and electrical systems at full power.

The ship returned to the shipyard under its own power Thursday, and will return to sea after the problem is addressed. The repairs are not expected to impact the ship’s delivery in March.

The first-in-class Zumwalt experienced several problems with a different system that has since been repaired.

The high-tech ships utilize new technology including a new electric-drive propulsion system.
