Reading some of the comments on various websites it is often as if a single comment has two distinct authors. For example some are seriously suggesting the way forward is to convert the Legend class high endurance cutter into an AEGIS FFG, restart FFG production because they are such powerful warships, or licence build Navantia F-100 FFGs because the LCS are so poorly armed and can't defend themselves, then when you ask about the other missions, i.e. mine warfare, the response is to keep building single role, difficult to deploy and support Avenger Class mine hunters, Cyclone class PBs etc.
Not every ship can be a high end DDG, but then again they don't need to be, but when talking global patrol and sea control missions, expeditionary mine warfare, special forces support, inshore (as opposed to open ocean) ASW, something able to self deploy, operate with minimal support and survive against unexpected low to mid level threats is needed, otherwise the USN ends up having to use a DDG or Amphib.
