Shipboard Passive Electro-Optical Infrared Development
Abstract
Shipboard Passive Electro-Optical Infrared (SPEIR) Block I will be an open architecture system that addresses near-term capability requirements and associated gaps identified in the 2019 SPEIR Capability Development Document (CDD). This program answers an urgent counter unmanned aircraft system operational need for the Fleet to provide an initial capability by FY26. The SPEIR acquisition leverages technology developed under the Office of Naval Research's (ONR's) Combined EO/IR Surveillance and Response System (CESARS) Science and Technology (S&T) effort, specifically related to the Shipboard Panoramic EO/IR Cueing and Surveillance System (SPECSS). SPEIR Block I will provide a common 360-degree EO/IR Electronic Support (ES) capability to surface ships 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 In-shore Attack Craft (FAC/FIAC), and Mobility. SPEIR Block I will consist of a passive Wide Field of View (WFOV) capability with a 360-degree field-of-view optical sensors for autonomous detection and tracking for 24/7 day/night shipboard situational awareness. SPEIR Block I will also include an enhanced, high resolution Narrow-Medium Field of View (NFOV) and laser range-finding capability that will provide 3D target tracking, identification, and threat assessment. SPEIR Block I will have limited integration with shipboard combat systems to exchange target track data and disseminate motion imagery. This program includes risk reduction initiatives for modeling and simulation, sensor protection counter-countermeasures, Sensor Fusion Algorithms and combat system track publishing to enable limited Combat System Integration (CSI). SPEIR Block II will be a future program that will build on the modular open system architecture of Block I to address longer-term capability requirements to include an expanded spatial coverage envelope, Periscope Detection and Discrimination (PDD) and Mine Like Object (MLO) avoidance. SPEIR Block II will also provide full combat system integration and will include a government software development and integration effort for Soft-Kill Coordination System (SKCS) to manage ES engagements. The FY25 budget request supports completion of core software builds and associated integration effort, and assembly of two full Engineering Development Models (EDMs), and program testing. Scope also includes execution of Milestone C (MS C), training curriculum development, execution of Environmental Qualification Testing (EQT) and Formal Qualification Testing (FQT), Operational Assessment (OA), and Modeling and Simulation (M&S) development and maturation. FY24 to FY25 funding decreases due to expected ramp down of developmental activities. Efforts will also include development of capability to integrate SPEIR with the AEGIS Combat System and planning for Land Based Testing (LBT). RDT&E costs are anticipated to ramp down increasingly 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.
