## Summary

This activity requests $19.3M in FY2027, 100% of project 3239, down 4.8% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - 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 counter-detection (1-to-1), time slide, and network nodes. - Continue research and development of proof-of-concept capabilities for spectrum mission planning decision aids and intelligent sectoring/cut-outs for radiating systems. - Continue research and development efforts for models to estimate effective Radio Frequency (RF) performance ranges of spectrum dependent systems in the complex electromagnetic environment (one-on-one and multi-on-one effects). - Continue to participate in Limited Objective Experiments (LOEs) to demonstrate incremental capability to Fleet users. - Continue development of a software architecture supporting mission module delivery of Real-Time Spectrum Operations (RTSO) capability on all platforms. - Continue development and integration of RTSO software and outputs with other software applications. - Continue to hold Fleet user engagements on new and enhanced software capabilities to improve usability, functionality, and applicability to user requirements. - Continue development of RTSO software releases, v2.4 and beyond, for afloat Fleet users in a cloud environment, including integration testing, cybersecurity authorization, and completing deployment configurations for all deployment environments. - Validate machine learning and software automation capabilities for increased future integration.

**FY2026 to FY2027 change.** The FY 2026 to FY 2027 decrease ($0.965M) is due to the completion of engineering work to validate current design for at least seven different ship classes.

## Before the request year

**FY2026 plans — current year.** - Complete engineering work to validate current design for at least seven different ship classes. - Begin development and integration of a new and increased capability for RTSO OFM and spectrum management design for seven different ship classes. - Continue research, development, enhancement and refinement of RTSO software cloud architecture, spectrum COP, live data ingest, detection and counter-detection (1-to-1), time slide, and network nodes. - Continue research and development of proof-of-concept capabilities for spectrum mission planning decision aids and intelligent sectoring/cut-outs for radiating systems. - Continue research and development efforts for models to estimate effective Radio Frequency (RF) performance ranges of spectrum dependent systems in the complex electromagnetic environment (one-on-one and multi-on-one effects). - Continue to participate in Limited Objective Experiments (LOEs) to demonstrate incremental capability to Fleet users. - Continue development of a software architecture supporting mission module delivery of Real-Time Spectrum Operations (RTSO) capability on all platforms. - Continue development and integration of RTSO software and outputs with other software applications. - Continue to hold Fleet user engagements on new and enhanced software capabilities to improve usability, functionality, and applicability to user requirements. - Finalize RTSO v2.3 release to afloat Fleet users in a cloud environment, including integration testing, cybersecurity authorization, and completing deployment configurations for all deployment environments.
