The USS Zumwalt, built at Bath Iron Works, has broken down in the Panama Canal.
In a statement, the Navy says the first-of-its-kind ship is remaining in Panama to address engineering issues. The ship is making its way from Maine to its eventual home port in San Diego.
The guided missile destroyer staged successful sea trials off Maine earlier this year. But once in Norfolk, Virginia, the Navy found a seawater leak in a propulsion shaft lubrication system, and union sources say BIW sent staff there to help repair the problem.
That problem did not disable the ship, the Navy said. But according to USNI News, the recent canal breakdown did, and it had to be towed to a port in Panama, sustaining minor exterior damage passing through a lock.
The publication says the breakdown may involve a heat exchange system and a seawater leak.
The Zumwalt is the first of three ships in the DDG 1000 class, with a combined price tag estimated at $22 billion.
BIW officials did not return requests for comment.
