## Summary

This activity requests $28.9M in FY2027, 56% of project UN4, up 9.2% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Continue feature development of CSC2 capabilities, including integration of S&T capabilities for sensor data analytics, non-CBRN sensor data, decision support tools, and data broker capabilities for internal and external data exchanges. Features will be delivered through quarterly software capability releases. This continues the ability to securely exchange, integrate, and manage data across multiple systems, platforms, and domains. Enable CSC2 capability delivery to be tailored to service-specific needs while ensuring data security, interoperability, and operational relevance. Incorporate additional Commercial Off-the-Shelf (COTS) and developmental sensor capabilities to the baseline for the Sensor Controller Manager to reduce disparate capabilities in the field. Provide program/financial management, costing, contracting, scheduling and acquisition oversight and product support for software development and experimentation with operational forces.

**FY2026 to FY2027 change.** Increase due to minor program adjustments and inflation.

## Before the request year

**FY2026 plans — current year.** Continued feature development of CSC2 capabilities, including baseline capabilities for Warning Reporting and Advanced Hazard Prediction for a Minimum Viable Capability Release (MVCR) in 3Q FY 2026. Initiated development of internal and external data broker capabilities to facilitate the secure exchange, integration, and management of data across multiple systems, platforms, and domains. Delivered features through quarterly software capability releases. Initiated aligning contracts to an agile workforce for the development of capabilities and integration into deployable CSC2 configurations. This ensured the features and capabilities had access to necessary data while ensuring security, interoperability, and operational relevance. Incorporated force protection sensor capabilities into the baseline for the Sensor Controller Manager to reduce disparate capabilities in the field. Provided program/financial management, costing, contracting, scheduling and acquisition oversight, and product support for software development and experimentation with operational forces.

**FY2025 accomplishments.** MVCR for CSC2 was completed and continued development of MVP prototype for CBRN Warning and Reporting decision support tools. Demonstrated integration and interoperability with CCMDs and service networks, enhancing battlespace awareness and accelerating decision-making. Conducted multiple service feedback events to refine capability development and support agile testing, evaluation, and engineering for future releases. Maintained quarterly deliveries of CSC2 capabilities.
