The Congress asked the Navy to study improvement programs on existing ships in place of the LCS program. In June 2009, Vice Admiral Barry McCullough, USN testified in a Senate Armed Services Committee meeting that the "Oliver Hazard Perry"-class frigates and minesweepers were too worn out to cover the gap if the LCS suffered further delays. Retired Admiral James Lyons, USN called for a $220 million common design with the U.S. Coast Guard's National Security Cutter (NSC) program to save costs and meet "limited warfare requirements". A Huntington-Ingalls study found that the NSC would be a better match for the listed mission set while lacking the LCS's mission modules to perform many missions.
