A missile hit does not automatically sink a sufficiently strong and well-compartmentalized ship. The ship can survive while losing the ability to carry out its mission. Whether that happens depends partly on redundant power supplies, sensors, and other systems that can replace damaged equipment. Wartime American destroyers combined physical survivability with redundancy intended to keep them useful after damage. The outcome remains conditional on the ship's design and the damage sustained.

Surviving a hit and retaining a mission are different problems
Compartmentalization can keep a ship afloat after a missile hit, while backup power and sensors help it continue its mission.
