**R-2A activity** of project UN7 — Understand (Op Sys Dev)  
**Program element:** 0607384BP — Chemical and Biological Defense (Operational Systems Development)  
**Component:** Defense-Wide · **Budget Activity:** 7  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $12.7M in FY2027, 18% of project UN7, up 78% 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 technical refreshment of CBRN DRS, Common Analytical Laboratory System (CALS), Analytical Laboratory System (ALS) Modification (MOD), M8, Enhanced Maritime Biological Detection (EMBD) and Joint Chemical Agent Detection (JCAD) - M4A1 Obsolescence. Plans include continue sensor modernization, support equipment obsolescence management, and market research of detection equipment for CBRN DRS, continue addressing obsolescence of Gas Chromatograph Mass Spectrometer (GC MS) system with an analytical system that will work within existing space and interoperability constraints for the ALS MOD and CALS, continue development of Next Generation Diagnostic System (NGDS) Sentinel Panel for use on the SPOTFIRE System for ALS MOD and CALS, continue modernization and identification of replacement technology of the M8 to increase the confidence in detection of traditional and emerging threats, continue software modernization and obsolescence management of electrical components on circuit card assemblies for EMBD, and begin technical refresh of the JCAD M4A1 by conducting performance and functional testing to prove form/fit/function equivalence of the JCAD-M4A2.

**FY2026 to FY2027 change.** Increase due to cost of additional scope and target of obsolescence activities in FY 2027 for the biological detection and CBRN DRS detection evaluation activities.

## Before the request year

**FY2026 plans — current year.** Continue technical refreshment of CBRN DRS, Common Analytical Laboratory System (CALS), Analytical Laboratory System (ALS) Modification (MOD), M8, and Enhanced Maritime Biological Detection (EMBD). Plans include addressing capability gap resulting from obsolescence of the current Gas Chromatograph Mass Spectrometer (GC MS) system within the CALS program with an analytical system that will work within existing space and interoperability constraints that will detect and identify various Volatile Organic Compounds (VOCs) and Semi Volatile Organic Compounds (SVOCs), obsolescence management and market research of detection equipment for CBRN DRS, continue modernization of the M8 to increase the confidence in detection of traditional and emerging threats, and continue software refreshments and electronics components obsolescence for EMBD.

**FY2025 accomplishments.** Continued technical refreshment of CBRN DRS, Common Analytical Laboratory System (CALS), Analytical Laboratory System (ALS) Modification (MOD), M8 Chemical Detection Paper, and Enhanced Maritime Biological Detection (EMBD). Addressed capability gap resulting from obsolescence of the current Gas Chromatograph Mass Spectrometer (GCMS) system within the CALS program with an analytical system that will work within existing space and interoperability constraints that will detect and identify various Volatile Organic Compounds (VOCs) and Semi Volatile Organic Compounds (SVOCs), obsolescence management of support equipment and conducting a verification and validation of a non-intrusive assessment technology insertion for the Chemical Biological Radiological Nuclear Dismounted Reconnaissance System (CBRN DRS), continued modernization of the M8 and start surety testing and user touch points to support changes to M8, and software refreshments and electronics components obsolescence for EMBD.
