### Project 3243 — Shipboard Passive Electro-Optical Infrared Development

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, and procurement of Low Rate Initial Production (LRIP) Lot 1 Long Lead Material (LLM) (2QFY25) and LRIP (3QFY26). The FY27 budget request supports software upgrades and the associated integration effort, and program testing. Scope also includes LRIP delivery, training curriculum development, commencement of Land Based Testing and continuing the Engineering & Manufacturing Development phase. Additionally, the completion of Modeling and Simulation (M&S) development and maturation, and completion of SPEIR Test and Certification are also planned in FY27. FY26 to FY27 funding decreases are due to the ramp down of developmental activities. Efforts will also include development of capability to integrate SPEIR with the AEGIS Combat System. RDT&E costs are ramping down in FY27 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.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** L3Harris (25.7, 56%), Lockheed Martin (7.5, 16%), APL (2.7, 5.9%), NRL (2.1, 4.6%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| SPEIR Block I Systems Engineering | 30.6 | 17.8 | 12.5 |
| SPEIR Block I Development | 61.3 | 36.2 | 33.2 |

### Project 3301 — Improved Capabilities SPY-1 Radar

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. 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) Backfits and Phase 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.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** AEGIS Techrep (1.4, 6.2%), NRL (1.1, 5.1%), SPA (0.8, 3.4%), MIT/LL (0.4, 1.7%).

## Mission & acquisition strategy

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.

Improved Capabilities SPY-1 Reliability, Maintainability, and Availability (RM&A) will design and develop an Ordnance Alterations (ORDALT) Package for fixes and modifications to known transmitter, signal processor, microwave tube (MWT), and logistic shortcomings. Lockheed Martin Corporation (Moorestown, New Jersey) was awarded a sole source, cost- plus-fixed-fee, level-of-effort job order under a Basic Ordering Agreement (BOA) via Naval Surface Warfare Center (NSWC) Crane. The contract supports the development and fielding of AN/SPY-1 Radar capability upgrades and reliability improvements in support of AEGIS combat system. Investment in development of SPY-1 RM&A improvements to address failure mechanisms and improve reliability.
