A design defect in the Freedom class Littoral Combat Ships made at Fincantieri Marinette Marine has forced the postponement of the commissioning of LCS21, the future USS Minneapolis-St. Paul.  The defect in the propulsion system deals with bearings in the combining gear’s high speed clutch.   Lockheed Martin, who partners with Fincantieri Marinette Marine to build the ships, said they are, in partnership with the U.S. Navy, aggressively pursuing a resolution to the gear issue the Freedom-variant Littoral Combat Ship is currently experiencing..  Defense News reported the Navy began looking into the gear issue after failures on the USS Detroit and USS Little Rock last year.
