## Summary

This activity requests $35.1M in FY2027, 50% of project UN7, up 32% 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 engineering, integration, and delivery of the CSC2 capability set in support of new features and follow-on capability releases (CRs). Initiate the transition and removal of the Legacy CBRN Information Systems, with CSC2 capabilities to be completed in FY 2028. Transition functions and features from the Mobile Field Kit (MFK), supporting accreditation, testing, and integration of select sensors and accelerating integration into CSC2. Supports continuous software developmental and operational testing on software updates and modernization efforts. Including the infrastructure for Continuous Integration/Continuous Delivery (CI/CD) development and processes to automatically build, test, and deploy new software capabilities. Provide program/financial management, costing, contracting, scheduling and acquisition oversight and product support for software redeployment and training to operational forces.

**FY2026 to FY2027 change.** Program/project funding transferred from another funding line. In FY 2027 funding transfers from MFK Project UN5/Understand to CSC2 Project UN7/Understand to accelerate the planned integration of MFK into CSC2.

## Before the request year

**FY2026 plans — current year.** Continue engineering, integration, and delivery of the CSC2 capability set in support of the Minimum Viable Capability Release (MVCR) delivered 3Q FY 2024 and the planned quarterly software releases that follow. Provide for the infrastructure for Continuous Integration/Continuous Delivery (CI/CD) software development and processes to automatically build, test, and deploy software capabilities. Maintain operational status and execute continuous engineering of fielded chemical and biological (CB) software systems (CBRN IS, JEM, and JWARN) until CSC2 replaces them across FY 2027-FY 2029. Continuous engineering includes updates to host architectures, operating systems, cybersecurity requirements, and North Atlantic Treaty Organization (NATO) standards. Provide program/financial management, costing, contracting, scheduling and acquisition oversight and product support for software redeployment and training to operational forces.

**FY2025 accomplishments.** Continue engineering, integration, and delivery of the CSC2 capability set in support of the Minimum Viable Capability Release (MVCR) and follow-on capability releases (CRs). Continue post-production software support of the Legacy CBRN Information Systems, until the CSC2 is available to be delivered. This continued development will include updates to host architectures, operating systems, cybersecurity requirements and North Atlantic Treaty Organization (NATO) standards. Supports continuous software developmental and operational testing on software updates and modernization efforts. Including the infrastructure for Continuous Integration/Continuous Delivery (CI/CD) development and processes to automatically build, test, and deploy new software capabilities. Provide program/financial management, costing, contracting, scheduling and acquisition oversight and product support for software redeployment and training to operational forces.
