Yeah, I don't know why the littoral combat ship was such a big problem. It's for near-shore patrol, which has to be the easiest job any navy has to do. Even the really piddly ones have to deal with that, and they do so with a wide variety of patrol boats, corvettes, and frigates. The USN could have picked any one of dozens of designs in current operation, made a few tweaks for taste, and put them in service.
