$7.5 billion destroyer lost propulsion in port shaft crossing Panama canal

USS Zumwalt (DDG-1000) is pier side following an engineering casualty the ship suffered transiting the Panama Canal. The guided missile destroyer will undergo repairs at a former U.S. naval station until its fit to complete its journey to Naval Station San Diego, Calif., U.S. 3rd Fleet spokesman Cmdr. Ryan Perry told USNI News.

The ship was in the midst of a southbound transit through the canal when it suffered the casualty, Under orders from U.S. 3rd Fleet commander Vice Adm. Nora Tyson, Zumwalt is now stopped for repairs at the former U.S. Naval Station Rodman

A defense official told USNI News on Tuesday the repairs could take up to ten days.

The ship lost propulsion in its port shaft during the transit and the crew saw water intrusion in two of the four bearings that connect to Zumwalt’s port and starboard Advanced Induction Motors (AIMs) to the drive shafts, a defense official told USNI News on Tuesday. The AIMs are the massive electrical motors that are driven by the ship’s gas turbines and in turn electrically power the ship’s systems and drive the shafts.

Before the casualty, the ship was set to arrive in San Diego by the end of the year and start weapon system activation period before joining the fleet as an operational warship sometime in 2018.

Zumwalt is the first of three in the $22-billion class. Michael Monsoor (DDG-1001) and Lyndon B. Johnson (DDG-1002) are currently under construction at BIW.
