Hybrid warships can lose focus in both missions

Combining two major roles in one hull looks economical in peacetime because a navy appears to buy broad coverage with fewer ships. In combat, however, a hybrid can meet an opponent optimized for either role and prove inferior in both. Compatible secondary functions such as point defense, naval gunfire support, or a backup anti-submarine capability can coexist, but the primary mission must still govern sensors, maneuvering, and command attention. An area-air-defense ship cannot let submarine hunting distract it from the air picture. A carrier exchanging gunfire likewise cannot coordinate reconnaissance effectively, potentially leaving the cruisers it supports surprised or outnumbered.
