In 2013, Captain Kenneth Coleman, the U.S. Navy's requirements officer for the program, identified the LCS as being especially vulnerable to tactical aircraft armed with standoff anti-ship missiles. Vice Admiral Thomas H. Copeman III is reported to be considering an upsized "Super" LCS, with space to install needed firepower, because he noted that the 57mm main gun was more suitable to a patrol boat than a frigate. Austal's vice president for sales, Craig Hooper, suggested that the ships should instead be used for UAV operations. Navy Secretary Ray Mabus has called the lack of identified missions for the LCS "one of its greatest strengths". The various modules all use the same Internet Protocol formats. In 2013 Congressional auditors found that the ships lacked robust communications systems and a USN review "uncovered classified deficiencies" in the ship's cyberdefenses.
