AN/SPS-48

The AN/SPS-48 is a three-dimensional air search radar system used by the United States Navy and other allied navies. It provides long-range surveillance, detection, and tracking of airborne targets, including aircraft and missiles. The radar operates in the E/F band (NATO G-band) and utilizes frequency scanning techniques to determine altitude, bearing, and range.

Specifically, the AN/SPS-48 is a solid-state radar, replacing earlier vacuum tube-based systems, which improves reliability and maintainability. It's designed to detect targets at significant ranges and to resist electronic countermeasures (ECM). The radar's antenna is typically a large, rotating array.

The system is often integrated with combat systems such as the Aegis Combat System, providing critical tracking data for weapons engagement. It plays a vital role in providing air defense capabilities for naval vessels and carrier strike groups. Later variants, such as the AN/SPS-48E, include improvements in signal processing and ECM resistance, extending its operational life and enhancing its performance against modern threats. Its data is vital for maintaining situational awareness in complex operational environments.
