A 2012 report by Rear Admiral Samuel Perez, USN, found that the ships lacked the manpower and firepower to complete the missions required by regional combatant commanders. The report found that the LCS is "ill-suited for combat operations against anything but" small, fast boats not armed with anti-ship missiles. It also found that the excessive beam (width) of the trimaran Independence class ships may pose a "navigational challenge in narrow waterways and tight harbors". The report also found that the contractor-based maintenance scheme for the ships had led to poorly supervised and unaccountable contractors leaving problems unresolved. As contract workers are required to be American, they must be flown out to any foreign ports visited by an LCS. A special panel was appointed to investigate "challenges identified". Twenty more bunks were installed to allow for a larger crew.
