When a modern missile ship becomes a battlecruiser

How should a 45,000-ton warship with 12-inch guns, 178 VLS cells, and aviation facilities be classified?

As a modern battlecruiser, because its displacement and combined gun, missile, and aviation battery exceed an ordinary cruiser role.

The hypothetical ship combines capital-ship displacement with triple 12-inch gun turrets, a corrected total of 178 vertical-launch cells, and an aft hangar and flight deck. At the initially stated missile count, it is classed only as a major combatant. Once the 178-cell figure is clarified, the answer changes to battlecruiser. Modern classification can rest on the combined scale of guns, missiles, aviation, and hull rather than on one weapon alone.
