The Ticonderoga class sat between destroyer ancestry and cruiser responsibilities. Added command facilities and the need to coordinate Aegis air warfare led to its redesignation as a cruiser in 1980. The ships were initially meant to support much larger nuclear-powered strike cruisers, but cancellation of those ships left the smaller Ticonderogas carrying the cruiser role. Their double-ended missile battery reflects the original air-warfare mission. The later DDG(X) comparison shows how little the label alone says about size or function.
