This activity requests $16.9M in FY2027, 18% of project UN3, up 488% 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

Verbatim from the R-2A exhibit for project UN3 of PE 0603384BP. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

- Demonstrate aerosol microsensor for long-range chemical detection that maximizes early warning for maximized decision making lead time for response. - Demonstrate and transition low-burden chemical agent vapor detection technology to inform donning and doffing decisions for individual protection.

FY2026 to FY2027 change

Program/project funding transferred from another funding line. Increase due funding transfer from project UN2 applied research to project UN3 advanced applied research for accelerated prototype field demonstrations, user feedback collection and data analysis, and technology optimization.

Before the request year

FY2025–FY2026: what came before

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

- Continue development toward a deployable microsensor development pipeline for improved size, weight, and power chemical and biological (CB) sensor prototypes. - Continue integration of mature chemical threat sensing and sampling system prototypes onto unmanned and manned platforms and perform test assessments. - Continue efforts to modernize detection prototypes to reduce false alarms and increase sensitivity and specificity. - Transition low size, weight, and power hyperspectral imaging technologies for the remote detection, identification, and quantification of chemical vapors. - Transition ballistic gas chromatography technology for air monitoring of chemical threats and verification of sensitive equipment decontamination. - Initiate development of new chemical sensors based on quantum metrology.

FY2025 accomplishments

- Continued development toward a deployable microsensor development pipeline for improved size, weight, and power chemical sensor prototypes. - Began integration of mature chemical threat sensing prototypes onto unmanned and manned platforms and perform test assessments. - Continued efforts to reduce false alarms and increase sensitivity and specificity for chemical detection sensor prototypes for increased decision making confidence.

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 18% of project UN3's FY2027 request and 5.5% of PE 0603384BP's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
