Agreed, but a lot of people think that part of the problem with the LCS stems from the lack of clarity on the precise nature of the littoral mission(s) that the USN envisages.
The Pentagon part of the USN apparently overestimates what is necessary. Small, say 110-130’ advanced fiber boats with the 30mm Bushmasters, Harpoons and Stingers, with assorted small arms (Mk19, M2) would fill the bill very well and would be cheap. All the technology exists. Hulls exist already manufactured by civilian companies. The Admirals definitely need to get out of bed with the contractors and fill the void with an affordable vessel.
