Which radar performs navigation, station keeping, and general surface search duties on DDG 51 class ships?

The AN/SPS-67(V) 3 radar system is specifically designed to perform navigation, station keeping, and general surface search duties, making it particularly well-suited for the roles required on DDG 51 class ships. Its capabilities are tailored to provide a comprehensive situational awareness of the marine environment, which is crucial for the operations of destroyers in a variety of missions.

This radar supports a range of functionalities, including tracking surface vessels, navigating safely through congested waterways, and ensuring the effective management of a ship's operations in various sea conditions.
