Advanced Above Water Sensors

Advanced Above Water Sensors encompasses several specific objectives. The Multi-Mission Signal Processor (MMSP) project aims to provide simultaneous Anti-Air Warfare (AAW)/Ballistic Missile Defense (BMD) multi-mission capability for DDG 51 class ships as part of the Aegis Modernization Program. This includes modifying SPY-1D transmitters to enable dual beam for reduced frame times and better reaction time, providing stability for all D(V) waveforms, and avoiding operational degradation. Additionally, the program supports the development of MMSP on Destroyers Commercial Off The Shelf (COTS) refresh and MMSP technology refresh. The FY24 budget request supports detailed hardware and software design of the SPEIR Block I system, completion of core software builds and associated integration effort, and procurement of material for Engineering Development Models (EDMs).

Furthermore, the Improved Capabilities for SPY-1 Radar project focuses on reliability, maintainability, and availability improvements to reduce cascading failures, mitigate obsolescence issues, and improve reliability in support of AAW and BMD missions. This includes developments such as Solid State Insertion to address Diminishing Manufacturing Sources and Material Shortages (DMSMS), Transmitter Noise Cancellation (TNC) development, Side Lobe Blanking (SLB), Ship-Based Non-Cooperative Target Recognition (SBNCTR) program Phases 2A and 3, Advanced Calibration Experiment (ACE) Phase 2, Elevated Radar Advanced Calibration Experiment (ERACE) Phases 1/2 and 3, Electronic Attack (EA), and Rapid Radar Capability Improvement Program (R2CIP). The FY24 budget request continues these development efforts to improve radar capabilities.

Lastly, the AN/SPS-49 Technology Refresh program aims to address continued degradation and low radar availability of the AN/SPS-49 Radar on the LSD 41/49 class ships. This includes Reliability, Maintainability, and Availability (RM&A) improvements and solid state technology insertions to reduce cascading failures and mitigate obsolescence issues. Additionally, this effort replaces key components such as transmitter, receiver, exciter, antenna elevation servo control, radar system control, display and signal data processor (SDP). The program also involves developing new software to mimic the current radar functions to maintain compatibility with internal and external interfaces. Funding is allocated to complete development, test and evaluation, validation and integration of a technology refresh of the below deck hardware for the AN/ SPS-49A(V)1 Long Range Air Surveillance Radar.

These programs collectively aim to enhance naval capabilities in above water sensors through technological advancements and system modernization.
