What is the role of a Guided Missile Cruiser (CG)?

The role of a Guided Missile Cruiser (CG) primarily involves air defense and surface warfare capabilities. These vessels are equipped with advanced radar and missile systems designed to protect carrier strike groups and other naval formations from aerial threats, including aircraft and incoming missiles. Additionally, they are capable of engaging surface threats with their guided missiles and naval gunfire support.

While guided missile cruisers may contribute to defensive operations and can participate in personnel transport to some extent, their core functions are centered around their ability to defend against aerial and surface threats effectively. Their versatility also allows them to engage in specific missions, including anti-submarine warfare and strike operations, but the primary focus remains on air defense and engaging in surface warfare. The other options do not accurately represent the CG's main operational capabilities as effectively as this one does.
