Description
Mission — Advanced Above Water Sensors
Multi-Mission Signal Processor (MMSP): 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 time, 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 on Destroyers Commercial Off The Shelf (COTS) refresh and MMSP technology refresh. MMSP/AEGIS Linear Processing System (ALPS) integration provides adjunct processing for data collection. Starting in FY25, funding has been realigned within PE 0604501N from PU 3232 to 3301 to gain contractual efficiencies and program flexibility. Shipboard Passive Electro-Optical/ Infrared (SPEIR) Block I provide surface ships a common 360-degree EO/IR Electronic Support (ES) capability that will passively find, fix, track, and target current/emerging threats in support of the following warfare missions: Anti-Ship Cruise Missile (ASCM) Defense, Counter-Unmanned Aircraft Systems (UAS), Counter-Fast Attack Craft / Fast Inshore Attack Craft (FAC/FIAC), and Mobility. SPEIR Block I will consist of a passive Wide Field of View (WFOV) capability with a persistent 360-degree field-of-view optical sensors for autonomous detection and tracking for 24/7 situational awareness. SPEIR Block I will also include an enhanced, high-resolution Narrow-Medium Field of View (NFOV) and laser range-finding capability to provide 3D target tracking, identification, and threat assessment. SPEIR Block II will be a future program that will build on the modular open systems architecture of Block I with an expanded spatial coverage envelope and will add the capability for Periscope Detection and Discrimination (PDD), Mine Like Object (MLO) avoidance, networked operations, and full integration with the Future Integrated Combat System. Status of SPEIR Block I Major Milestones: Milestone B completed 3QFY22, procurement of Low Rate Initial Production (LRIP) Lot 1 Long Lead Material (LLM) (2QFY25), and Milestone C LRIP (2QFY26). 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. The FY26 budget request continues the development efforts of ACE Phase 2, SBNCTR Phase 2A, TNC Phase 1/2, SLB Integration and Test (I&T), and EA improvements, and commences ERACE Phase 3. In addition, the FY26 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 Engineering Change Proposals (ECP) and software updates, and DMSMS Tech Solutions and completes Future Signal Processor (FSP) Analysis of Alternatives (AoA). 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. AN/SPS-49 Technology Refresh: FY22 was the last year of funding for this program. AN/SPS-49 is the only Air Surveillance Radar on the LSD 41/49 class ships. Continued degradation and increasingly low radar availability of the AN/SPS-49 Radar is greatly impacting deployed missions, impacting safety of flight and affecting LSD Air Warfare capability and operations and as a result, AN/SPS-49 Technology Refresh is required. This AN/,SPS-49 Technology Refresh will include Reliability, Maintainability, and Availability (RM&A) improvements and solid state technology insertions which will reduce cascading failures and mitigate obsolescence issues. In addition, this effort replaces key components to include: transmitter, receiver, exciter, antenna elevation servo control, radar system control, display and signal data processor (SDP). A digital receiver/exciter (DREX) with high-performance computing technology will be a key component in the new system. The current SPS-49 radar has no software so new software is being developed to mimic the current radar functions to maintain compatibility with internal and external interfaces. This effort will improve SPS-49 electronic protection, have increased surveillance range and increased slow moving small target detection, as well as reduce total ownership cost with lower unit cost and smaller size/weight/power requirements. Funding is also 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.

Status of SPEIR Block I Major Milestones: Milestone B completed 3QFY22, procurement of Low Rate Initial Production (LRIP) Lot 1 Long Lead Material (LLM) (2QFY25), and Milestone C LRIP (2QFY26). The FY26 budget request supports software upgrades and the associated integration effort, and program testing. Scope also includes execution of Milestone C (MS C), training curriculum development, completion of Environmental Qualification Testing (EQT) and Formal Qualification Testing (FQT), and continuation of Modeling and Simulation (M&S) development and maturation. FY25 to FY26 funding decreases due to the ramp down of developmental activities. Efforts will also include development of capability to integrate SPEIR with the AEGIS Combat System and Land Based Testing (LBT). RDT&E costs are ramping down in FY26 as a result of completion of Integration & Development Test planning, the majority of core software development, EDM material procurements, and all three (3) EDMs are assembled and integrated to support the execution of developmental test events prior to program transition to the Production phase.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
