**R-2A activity** of project 646438 — Joint Space Integration Technology  
**Program element:** 1206438SF — Space Control Technology  
**Component:** U.S. Space Force · **Budget Activity:** 4  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $15.7M in FY2027, 100% of project 646438, down 37% 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.** Completed software development of release 1.6. Continue research, develop and validate software for enhanced modeling and simulation of regional ionospheric and signal propagation effects to forecast space domain impacts on joint force weapon systems. Integrate model output into weapon system tailored visualizations to improve multi-domain mission planning and execution. Begin development of software release 1.6.1 and 1.6.2. Software release 1.6.1 completes open system interface implementation with introduction of new capabilities and validate results during campaign planning, exercises, and war games. Software release 1.6.2 completes data source redundancy for software that supports Combatant Commanders. Continue to develop, test, and provide training for new or updated tactics, techniques, and procedures enhanced by MASE for operational users. Integrate new traditional and nontraditional data sources into models to improve space warfighting decision processes. Rapidly develop, test, and deploy new system features in response to continuously evolving threats to U.S. forces. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain. Activities may include, but are not limited to program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility.

**FY2026 to FY2027 change.** FY 2027 reduction reflects phasing of program into sustainment.

## Before the request year

**FY2026 plans — current year.** Research, develop and validate software for enhanced modeling and simulation of regional ionospheric and signal propagation effects to forecast space domain impacts on joint force weapon systems. Integrate model output into weapon system tailored visualizations to improve multi-domain mission planning and execution. Complete software development of Major Release 1.5, and begin development of software for Major Release 1.6 of new capabilities and validate results during campaign planning, exercises, and war games. Develop, test, and provide training for new or updated tactics, techniques, and procedures enhanced by MASE for operational users. Integrate new traditional and nontraditional data sources into models to improve space warfighting decision processes.
