Harris Corporation Awarded $113 Million US Navy Radar Upgrade Contract
Harris Corporation Awarded US Navy Contract to Upgrade AN/SPS-48E Radars to SPS-48G
Harris Corporation has received a four-year, $113 million contract from the U.S. Naval Sea Systems Command (NAVSEA) to upgrade the Navy's primary long-range, three-dimensional defense radar. The contract includes an initial $39 million order and three one-year options. The contract was received in the first quarter of Harris' fiscal 2016.
Harris was awarded the contract under the Navy's Radar Obsolescence and Availability Recovery (ROAR) program to upgrade AN/SPS-48E radars to the more advanced SPS-48G version, which uses a modern solid-state transmitter. This approach increases fleet readiness to address emerging threats, while lowering the Navy's total cost of radar ownership.
The AN/SPS-48G(V)1 only affects the layout of the below-deck units. The program of record is to back-fit the existing AN/SPS-48E population with the AN/SPS-48G(V)1 variant from 2011 through 2020. The intention is to have this configuration support Fleet 3D air search requirements for the ship classes that have AN/SPS-48G(V)1 through 2050 and beyond. The AN/SPS-48G(V)1 replaces the current 1st and 2nd stage RF amplifiers (Unit 1) with a Solid State Transmitter and combines the existing Receiver (Unit 9), Processor (Unit 10), and Auxiliary Detection Processor (Unit 15) cabinets into a single equipment cabinet; all of which provides an 87% reduction in the number of Lowest Replaceable Units. Mean Time Between Critical Failure or the AN/SPS-48G(V)1 is also improved over the AN/SPS-48E(V) by 104% based on 16 years of historical AN/SPS-48E(V) data, and with associated improvements in both operational availability and capability.
According to the U.S. Navy, the AN/SPS-48G is a long-range, three-dimensional (3D) Air Search Radar that will be installed on CVN, LHA, LHD, and LPD 17 class ships. The AN/SPS-48G is used to find full volumetric detection data for Ships Self Defense System and the Cooperative Engagement Capability (CEC), 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.
Hear the Navy ROAR: Radar Upgrade Kits for US Ships
The AN/SPS-48E radar was introduced into the US Navy’s fleet in the mid-1980s. It is a medium-range, 3-dimensional (height, range, and bearing) air search radar whose primary function is to provide target position data to a weapon system and a ship command and control system.
Two decades later, the US Navy is upgrading the radar using AN/SPS-48G(V) radar modification kits
[pdf] as part of its Radar Obsolescence, Availability Recovery (ROAR) program. ROAR is intended to extend the service life of AN/SPS-48 radar systems on aircraft carriers, amphibious assault ships, and land-based sites. This ROAR program is upgrading more than 30 radar systems. The upgrades include adding a solid state transmitter, a digital receiver/ processor, open architecture, and a tactical integrated digital environment…

The Applied Physics Laboratory, in its role as technical advisor to the Navy for the AN/SPS-48E radar, designed and operates a coherent data collector to analyze radar system performance. This article presents examples of how coherent data analysis has helped the program development efforts and provided insights into the performance of the AN/SPS-48E radar. The topics discussed include beam-to-beam interference, wide-band limiting, beam sequence effects, and characterization of land clutter.
