# 4) Chemical and Biological Wearables (CB WEARABLES)

**R-2A activity** of project UN5 — Understand (SDD)  
**Program element:** 0604384BP — Chemical and Biological Defense Program - EMD  
**Component:** Defense-Wide · **Budget Activity:** 5  
**Vintage:** President's Budget PB2027  
**Canonical URL:** https://hitchintel.com/programs/0604384BP/UN5/a3  
**Parent:** https://hitchintel.com/programs/0604384BP/UN5

## Summary

This activity requests $10.0M in FY2027, 5.3% of project UN5, up 12% 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.** Efforts support advanced experimentation activities with joint warfighters to identify CB defense capability gaps across the services. As part of a coordinated experimentation campaign, the program will use BA5 to verify, validate, and integrate physiological monitoring software capabilities into the hardware-focused decision support tools developed under the CB WEARABLES-ENBD program.

**FY2026 to FY2027 change.** Program/project funding transferred from another thrust area. Efforts transitioned from BA4 to BA5 in support of System Development and Demonstration activities.

## Before the request year

**FY2026 plans — current year.** Efforts support advanced experimentation activities with joint warfighters to identify CB defense capability gaps across the services. As part of a coordinated experimentation campaign, the program will use BA5 to verify, validate, and integrate physiological monitoring software capabilities into the hardware-focused decision support tools developed under the CB WEARABLES-ENBD program.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 9.0 |
| FY2027 | Request | 10.0 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
