A wargame held by the Naval War College demonstrated the possibility of using the LCS in open water operations to assist carrier battle groups and guided missile destroyers. The LCS was found to be more useful in open water operations than previously considered. The wargame found that an LCS operating the ASW package could perform the mission, which freed up a destroyer that would normally perform the mission to contribute to the lethality of the strike group. Submarine hunting ability is increased by the combination of a destroyer's towed array and hull-mounted sonar and an LCS' variable depth sonar.
