What project UN4 buys

The Understand Advanced Component Development and Prototypes (ACD&P) Project provides the Joint Force the ability to continually receive information about the chemical and biological (CB) situation at a desired time and place by detecting, identifying, and quantifying CB hazards in air, water, or on land, and on personnel, equipment or facilities. Efforts also develop a clear understanding of the current and predicted CB situation; collect, query, and assimilate information from sensors in real time to inform decisions and provide impacts of CB hazards. Efforts included in this Project are: (1) Advanced Differential Diagnostics (ADD) (2) Advanced Emerging Threat Defense (AET DEFENSE) (3) Colorimetric Indicator (CIND) (4) Chemical Biological Radiological Nuclear Support to Command and Control (CSC2) (5) Far Forward Biological Sequencing (FFBS) - Increment 2 (6) Genomic Enabled Sequencing (GENOMES) (7) Multi Phase Chemical Sampling and Analysis (MPCSA) (8) Surveillance and Pathogen Characterization-Enhanced Biological Defense (SPCHAR-ENBD) (9) Physiological Monitoring Sensor Suite (PM2S) (10) Chemical and Biological Wearables (CB WEARABLES) (11) Non-Targeted Sequencing Identification System (NSIS) (12) Congressional Ultra-Compact Hyperspectral Imaging Chemical Detector (CONG UCHI CD)

11 accomplishments / planned programs

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
