Which ship classes are equipped with the Aegis Weapons System and AN/SPY-1 Phased Array Radar?

The Ticonderoga-class cruisers (CG 47) and Arleigh Burke-class destroyers (DDG 51) are equipped with the Aegis Weapons System and the AN/SPY-1 Phased Array Radar, making this the correct answer. The Aegis system is a powerful integrated combat system that allows these ships to detect, track, and engage multiple targets simultaneously, including both air and missile threats. The AN/SPY-1 radar, utilizing advanced phased array technology, provides continuous, all-weather surveillance and target tracking capabilities, which are crucial for modern naval warfare.

In contrast, the other classes mentioned do not utilize the Aegis system. The Independence-class and Freedom-class ships are part of the littoral combat ship (LCS) program, which was designed for shallow-water operations with different combat systems. The Wasp-class and America-class are amphibious assault ships focused on supporting ground forces with a different operational approach. Lastly, the San Antonio-class and Whidbey Island-class vessels are designed primarily for amphibious operations and mine warfare, lacking the advanced air defense capabilities provided by the Aegis system. Therefore, while all these classes serve vital roles within the Navy, only the Ticonderoga and
