Improved Capabilities SPY-1 Radar

Abstract

Improved Capabilities for SPY-1 Radar: These Reliability, Maintainability, and Availability (RM&A) improvements and solid state technology insertions are intended to reduce cascading failures, mitigate obsolescence issues, and improve reliability in support of Anti-Air Warfare (AAW) and Ballistic Missile Defense (BMD) missions while still providing AN/ SPY-1 Radar Total Ownership Cost Reductions. Improvements, such as Solid State Insertion to address Diminishing Manufacturing Sources and Material Shortages (DMSMS), will yield reductions in annual fleet maintenance costs and is a top fleet requirement as part of the AEGIS Wholeness initiative. In addition to RM&A improvements, warfighting improvements funded in this line includes the following: Transmitter Noise Cancellation (TNC) development includes hardware/software to counter low radar cross section, low altitude threats. Side Lobe Blanking (SLB) addresses shortfalls in mixed electronic attack environment while in an Integrated Air and Missile Defense (IAMD) mode. The Ship-Based Non-Cooperative Target Recognition (SBNCTR) program Phase 2A will develop algorithms to provide classification for targets. Advanced Calibration Experiment (ACE) Phase 2 is being incorporated into Baseline 9. Elevated Radar Advanced Calibration Experiment (ERACE) Phases 1/2 and 3 will incorporate into Baseline 9. Electronic Attack (EA) and Rapid Radar Capability Improvement Program (R2CIP) develop solutions for evolving EA threats. The development of MMSP provides 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 capability is utilized for DDG 113 and follow new construction and Aegis Ashore. Modifies SPY-1D transmitters to enable dual beam for reduced frame times and better reaction times, provides stability for all D(V) waveforms, and avoids operational degradation. The SPY-1 radar system detects, tracks, and supports engagements of a broader range of threats. MMSP improves performance in littoral, ducted clutter, electronic attack (EA), and chaff environments and provides greater commonality in computer programs and equipment. This effort also provides for the development of MMSP-Restoration (MMSP-R) to support system security requirements on Destroyers Commercial Off The Shelf (COTS) refresh and MMSP/MMSP-R technology refresh. Starting in FY25, funding from MMSP PU 3232 has been realigned into SPY-1 PU 3301 to gain contractual efficiencies and program flexibility. The FY25 budget request continues the development efforts of SBNCTR Phase 2A, TNC Phase 1/2 and EA improvements, completes SLB Technology Development and ERACE Phase 1/2, and commences ACE Phase 2 and SLB Integration and Test (I&T). In addition, the FY25 budget request continues efforts realigned from PU 3232, AEGIS Capability Build (ACB) 16 Radar Requirements and Analysis and MMSP Technology Refresh/Diminishing Manufacturing Sources and Material Shortages (DMSMS) Solutions, continues ACB 16 COTS Refresh, MMSP/MMSP-R technology refresh to support Aegis Modernization, and MMSP Engineering Change Proposals (ECP) and software updates, and commences DMSMS Tech Solutions. MMSP-R includes software updates required on new computer platforms. Engineering efforts will be required to assess alternate technologies and determine optimal MMSP architectural solutions, which will include system security requirements.
