GCS looks like a LCS light to me.
Heh, its not a fair comparison really, for you.
Your LCS’ are little corvette-sized pop boats that absolutely cannot sustain themselves in a war environment. Overpriced, underarmed, would be absolutely shocking in a shooting war.
Whereas, the CGS, well, that is indeed a ship of the line. And ho, costs less too, with more hands, more capacity, more offensive and defensive weaponry. Oh and they will also have the very towed array in the world, same as the T23’s.
A comparison with the replacements of the River’s would have been much better for you, although actually used in very, very different roles. The replacement corvettes will be for EEZ patrols only. Which actually is where your LCS’ need to be based.
