Which system is responsible for primary shipboard surface search?

The SPS-73 is indeed the system responsible for primary shipboard surface search. This radar system is designed specifically to provide surface surveillance capabilities, allowing naval vessels to detect and track surface contacts effectively. The SPS-73 operates using advanced radar technologies to assist in navigation, target acquisition, and situational awareness, which are critical for maritime operations.

This radar is particularly utilized on various classes of naval ships and is known for its versatility and reliability in diverse maritime environments. Its ability to discriminate between different classes of surface vessels makes the SPS-73 an essential tool for modern naval operations, ensuring that ships can maintain safety and operational effectiveness in busy or contested waters.

While other radar systems mentioned, such as the SPS-48G and SPS-49A, serve specific functions related to air search and tracking, and the WSN-7 is primarily a navigation system, the SPS-73 stands out as the dedicated surface search radar. This clarity in function solidifies its role in shipboard operations, making it the correct choice for primary surface search.
