The AN/SPS-48E and the AN/SPS-48G are the two variants of the AN/SPS-48 radar presently in service with the Navy. The AN/SPS-48G has progressively been replacing the AN/SPS-48E starting in fiscal 2011 and continuing through fiscal 2028. This order is for the development, testing and delivery of the AN/SPS-48G(V)1 radar data processor software version 2.0.0 and radar display and control function software version 2.0.0, firmware updates for the I/Q processor and synchronizer and other hardware changes.

This order will implement a subset of the advanced training domain requirements, correct radar performance issues and perform the engineering and development of any hardware changes that might be necessary. Work is expected to be complete by November 2022. Fiscal 2020 research, development, test and evaluation (Navy) funding in the amount of $2,277,670 will be obligated at time of award and will not expire at the end of the current fiscal year.

The AN/SPS-48G is a long-range, three-dimensional (3D), air search radar that is progressively being installed on CVN, LHA, LHD and LPD classes of ships, replacing the AN/SPS-48E. As of the end of 2016, the AN/SPS-48G is already installed or in the process of installation aboard CVNs 68-72, CVNs 68-76, LHDs 1-4 and 7-8, LHA 7, and LPDs 26-27.

The AN/SPS-48G is used to provide full volumetric detection data for the Ship Self Defense System (SSDS) via the Cooperative Engagement Capability (CEC) or the SYS-2 tracker; Air Intercept Control; Anti-Ship Cruise Missile detection including low elevation and high diver targets; backup aircraft marshalling; and the new Hazardous Weather Detection and Display Capability.

The AN/SPS-48G radar is employed on U.S. Navy ships and provides 3D volume air surveillance. Once installed on the ship, the radar is no longer transportable and becomes shipboard permanent equipment until removed. The radar is integrated with a track management system, such as the CEC or the AN/SYS-2 Integrated Automated Detection and Tracking system, to provide air search information to the Combat Information Center watch team.

The has a maxim range detection of 370 km with a maximum altitude of 30,000 m and can track targets up to 69 degrees in elevation. The AN/SPS-48E is capable of providing target range, bearing and altitude information using a frequency-scanning antenna using a range of different frequencies in E band and F band with three power modes: high, medium and low.
