### Project 3239 — Real-Time Spectrum Operations (RTSO)

The Real-Time Spectrum Operations (RTSO) program develops tools, processes, and algorithms to conduct spectrum planning, spectrum sensing, and monitoring of the electromagnetic (EM) environment; characterize and predict electromagnetic (EM) environmental effects (E3); and manage and maneuver to avoid or mitigate electromagnetic interference (EMI) and EM vulnerability of Navy platforms. RTSO supports Navy and Marine Corps EM Spectrum Operations for global spectrum usage and allocation planning. RTSO researches the effects between shipboard transmitters and receivers and EM system interactions with the other systems installed on units within a strike group. The program developed a capability to sense and monitor shipboard EM spectrum usage and provides information to validate spectrum plans in support of Emissions Control (EMCON) within the strike group. RTSO software validates and displays spectrum plan compliance with a spectrum common operational picture. This EM spectrum management aid, combined with an Own Force Monitoring (OFM) sensor input, supports Battlespace Awareness and Information Operations. These self-awareness and validation capabilities greatly enhance the Navy's ability to perform command and control of the EM spectrum warfighting domain. In FY 2027, the RTSO program will continue to develop and integrate new capabilities for RTSO OFM and spectrum management and design across various Navy and Military Sealift Command (MSC) ship classes. Research and development efforts will focus on enhancing RTSO software, including cloud architecture, spectrum management, and detection capabilities. Additionally, RTSO will explore proof-of-concept capabilities, such as spectrum mission planning decision aids and intelligent sectoring, as well as models to estimate Radio Frequency (RF) performance ranges in complex electromagnetic environments. The program will also participate in Limited Objective Experiments to demonstrate new capabilities to Fleet users and develop software releases for afloat users in a cloud environment. Furthermore, RTSO will validate machine learning and software automation capabilities to inform future integration and development.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |

| Real-Time Spectrum Operations (RTSO) | 20.5 | 20.2 | 19.3 |

### Project 0706 — EMC & RF Mgmt

Electromagnetic Compatibility (EMC) and Radio Frequency (RF) Management Program: This project develops tools, processes, and algorithms to identify and mitigate Electromagnetic Interference (EMI) sources for Navy systems and platforms. (a) It will support the research, development, testing, and evaluation of electromagnetic compatibility criteria and frequency management to support afloat electromagnetic spectrum operations. The RF EMC criteria will be enhanced to include new RF systems and to comply with fleet operational requirements and streamline Strike Force frequency management processes. It will provide automated Spectrum Management (SM) compatibility criteria for development of operational task communication and radar/weapon plans to support fleet deployments, exercises, and contingency operations. It will provide identification and mitigation of EMI in Navy, North Atlantic Treaty Organization (NATO), Allied, Ashore and Joint Combat Operations. It will provide analysis related to spectrum reallocation proposals to assess impacts on Navy operations and systems, as well as for the Spectrum Supportability Risk Assessments. It will assist numbered fleet commands and DoW commands with determination of EMC criteria and processes to maximize ships' ability to operate in contested and congested environments. (b) It will support the Shipboard Electromagnetic Compatibility Improvement Program (SEMCIP) to identify, engineer, and evaluate effectiveness of potential EMI corrections. The program also characterizes and quantifies the operational impact of EMI problems on system's mission performance. (c) It will support the Nuclear Electromagnetic Pulse (EMP) Survivability Program. The program assesses the EMP survivability of all mission critical systems and funds development of a hardness assurance and maintenance program. It will develop improved modeling capability to reduce hardness validation costs at delivery and over the lifetime of the system/platform. The program develops new and updated design criteria, test methodology, test limits, and survivability validation procedures for all Navy systems, ships, submarines and shore facilities.
