The Crusader is the modern equivalent of the battleship. It is cool looking but would be taken out in the first minutes of a confrontation with a serious foe.
Actually, when backed by a robust sensor and information-warfare system, it's unbeatable.
The real problem is that so is dang near anything else.
I don't think there's a counterbattery radar made that will survive an hour of operation while facing a US division or corps.
