Instead, they have proposed but never added the half-baked fire support weapons that never survived the testing process.
I asked my buds at Dahlgren what the LCS was designed to do and they said "to sink in shallow water".
Not much shore support you can do with a pop gun. They should have at least used a 3” so they would have been potentially useful defending the Great Lakes from Canada.
Maybe they can be modified for use by the Coast Guard for interdiction.
