When the news of the breakdown reached Capitol Hill, Sen. John McCain, chairman of the Senate Armed Services Committee, told Navy Times that the plant issues were troubling and called for accountability.

“Reporting of a complete loss of propulsion on USS Milwaukee (LCS 5) is deeply alarming, particularly given this ship was commissioned just 20 days ago,” McCain said. “U.S. Navy ships are built with redundant systems to enable continued operation in the event of an engineering casualty, which makes this incident very concerning.

“I expect the Navy to conduct a thorough investigation into the root causes of this failure, hold individuals accountable as appropriate, and keep the Senate Armed Services Committee informed.”

At the time of its commissioning critics said the $437 million ship still hadn’t met expectations.

USS Milwaukee (LCS-5) is a Freedom-class littoral combat ship of the United States Navy which is named after the city of Milwaukee, the largest city in Wisconsin.
