I said at the start of this thread and I will say again, the LCS is not capable of dealing with other corvettes and FAC. The threat of pirates, drug-runners and Iranian speedboats is not sufficiently serious to warrant the building of 20 x $500 warships. There is an absurd over-duplication of weapons all directed at responding to a largely non-existent and trivial threat. The 30mm guns, the 57mm gun, the 50 Cal guns, Griffin - those weapon systems are no good for anything other than speedboat plinking. A Koronet anti-tank missile would do a lot of damage to LCS let alone something even larger.
What LCS needs to be is; -
A stealthy, land-attack ship with adequate self-defense.
What the LCS is just now;-
An ultra-fast ocean-going, coast-guard cutter.
