Second Zumwalt-class Destroyer Is Forced To Stop Builders Trials Because Of Electrical System Problems

The guided-missile destroyer USS Zumwalt (DDG 1000) arrives at its new homeport in San Diego on Dec. 8, 2016. US Navy photo.

The second-in-class Zumwalt destroyer was forced to stop builder trials early and to return to the General Dynamics Bath Iron Works shipyard in Maine, Naval Sea Systems Command said, according to USNI News.

The equipment failure occured a day after USS Michael Monsoor (DDG-1001) left Bath Iron Works on December 4. The ship returned to the shipyard on December 5 to solve its problem with harmonic filter.

“Harmonic filters are used in complex electrical systems to prevent unintended power fluctuations from damaging sensitive equipment.

The loss of the filter prevented the ship from running its complicated electric drive system at full power as part of the testing that was intended to be carried out during the trials,” a report by USNI News reads.

The first of the class destroyer USS Zumwalt also experienced several high-profile mechanical failures after it was delivered to the US Navy. One of the incidents took place while it was transiting the Panama Canal.

    Ships look like ships for a number of reasons. Most of those reasons are that the design of ships has evolved, over many thousands of years, into something that works. This design is not stable, and it only works on the very edge of computer controlled stability. The last time a design this bizarre was tried was the Russian turtle ship of the Russo-Japanese war; they didn’t work. This ship may be have been designed by the indispensable, and may be crewed by the exceptional, but the hull design is inherently unstable.
