The thing is the USN has largely worked out the kinks with the LCS now and has the modules available for them that they were meant to have when introduced. But they were hugely over budget and the whole process of designing these things has been pretty much your classic example of the IMC at work and with political support to get these things built.
The USN should have just gone for a replacement for the OHP class which they are doing now, although its going to be a FAR more advanced ship, without going into Sea Pyramid levels of tech. The Greeks have bought 4 of the LCS in a new arms deal with the US recently which is quite an arms deal by the looks of it.
They're buying 40 F-35A, two batallions of Bradleys, four old USCG cutters of the

The LCS suffered from kitchen sink syndrome/project bloat and tried to do too much on too small a platform, but with monied interests behind it, and jobs on the line, it was basically too big to fail, so they had to pour money into it.
