What project 3239 buys
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.
Project 3239 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

|---|---|---|
| FY2025 | Actual | 20.5 |
| FY2026 | Enacted | 20.2 |
| FY2027 | Request | 19.3 |
| FY2028 | Outyear | 18.7 |
| FY2029 | Outyear | 18.9 |
| FY2030 | Outyear | 19.2 |

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
- Continue development and integration of a new and increased capability for RTSO OFM and spectrum management design for different Navy and Military Sealift Command ship classes. - Continue research, development, enhancement and refinement of RTSO software cloud architecture, spectrum COP, live data ingest, detection and…
