The LCS and the F-35 are two weapon systems that have ignored history. Specialized types have outperformed generalized types.
I'll start with the F-35. The concept that one aircraft could meet the needs of all three services came from some moron who never read a history book. The F-4, with its more limited goals, was at best a serviceable aircraft once it had a gun and was never great.
Then we took the F-4 concept and gave it steroids for the F-35. In the end, we ended up with three different airplanes that suffer from a common design. The F-35B is the only variant that has the potential to be great, as its requirements drove the design of the others. The proponents can tout out the stealth and electronics they want but other nations will catch up (by theft probably) and have better capabilities on better airframes.
Likewise, the concept that the LCS could be transformed into different types of ships using interchangeable modules is a sick joke. The Secretary of the Navy behind the LCS was an MBA as was the Secretary of Defense who was behind the F-4 without guns.
