With Ships' Commissioning Delayed, New Mayport LCS to Test Answer to 'Class Design Defect' The USS Minneapolis-Saint Paul is launched into the Menominee River from Fincanteiri Marinette Marine in Marinette Wis., on Saturday, June 15, 2019. (Rick Gebhard/The Eagle Herald via AP) 16 Feb 2021 Warships whose commissioning is on hold will test a solution to a “class design defect” affecting all the littoral combat ships at Naval Station Mayport, Navy officials have concluded. The Navy decided last month to stop taking delivery of new LCS because of a problem in the ships’ system for merging power from multiple engines to move the vessels at the rapid speeds they’re designed for.
