Basically all the current OHP class has is one three inch gun, torpedo tubes and helicopter and a CIWS. Much more than the LCS which has no ASW weapons other than the helicopter. The missile system which provides AAW and some anti surface capability was deactivated and removed a decade ago.
And they are old, perhaps a decade of life left, but at what cost versus a newer class.
The Russians make some splendid small warships, for example;

Also the Spanish. The USA has not kept up, and the LCS is a disaster.
