## Summary

This activity requests $31.3M in FY2027, 51% of project 645352, down 25% 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.** - SAINT will continue to develop and expand on work from FY 2026, moving to more advanced tuning and testing of the prototype using new operational data feeds anticipated to become available in FY 2027. - SAINT will continue to assess and improve prototype performance in maintaining custody of adversary high value moving targets in support of dynamic targeting. This includes maturing the autonomous fusion of these new data sources with legacy data and determining advanced methods to optimize the collection strategies for these data sources in a way that extracts key target features that contribute to improved kinematic accuracy and target identification (ID) associated with priority adversarial targets. This will expand SAINT's capability to fuse Multi-INT data sources and explore integration into key edge environments to support a distributed operational network and associated concept of operations (CONOPS). - SAINT will continue to participate in operational exercises and tests, moving forward on the path to successful transition to DAF PAE C3BM.

**FY2026 to FY2027 change.** FY 2027 decreased by $10.441 million compared to FY 2026 in accordance with planned shift in focus on supporting final capability development, test, maturation and transition activities to DAF PAE C3BM.

## Before the request year

**FY2026 plans — current year.** - SAINT conducts tests with live operational data from existing sensors and new advanced sensor systems in a fully integrated system test. - The SAINT program continues development with acceleration of the build and testing an operational prototype for the Air Force Custody Engine to make up for the reductions in FY 2025, minimizing operational impacts. - SAINT continues to improve the ability to maintain continual custody of high value moving targets through cooperative and autonomous orchestration using cross-service, cross-agency, and commercial sensing capabilities to inform battlespace management nodes and ISR collection nodes among the JADC2 enterprise, completing key achievements towards successful transition. The SAINT program continues to assess the Custody Engine prototype and its ability to extend to additional critical software infrastructure supporting data object management services, battle management services, and sensor and platform orchestration. - New data sources and higher fidelity sensing, weapon and target models are being integrated with the SAINT prototype in FY 2026 for the purpose of further tuning and assessing the Custody Engine performance in operationally relevant conditions. - The SAINT program continues to participate in joint exercises to gain operator utility feedback. Incremental deliveries to C3BM's Battle Network Architecture continue to occur to enable prototype transition and integration activities.
