## What project 675186 buys

This project supports special SIGINT studies as well as the development and integration of advanced SIGINT capabilities for special programs including, but not limited to: quick reaction capability sensors, processing, exploitation, and dissemination associated with these systems, and other efforts approved by the USAF SIGINT Capabilities Working Group (SCWG). Development efforts will include, but are not limited to: new signal sets, antenna improvements, sensitivity upgrades, data distribution upgrades, and new/advanced deployment capabilities. This project provides the warfighter near term combat capabilities with increased capability improvements, accomplished as technologies and risks achieve satisfactory levels. Sensors will be integrated and tested on various platforms including the MQ-9A Unmanned Aerial System.

**R-3 lines of work:** Product Development; Test and Evaluation.

### SIGINT Development

**FY2027 planned work.** - Will continue to modernize SIGINT systems used by the MQ-9A and other platforms. Additional details are classified.

**FY2026 to FY2027 change.** Funding decreased due to a database error. $2.882M will be realigned from COMPASS BRIGHT [675185] for a total of $8.664M. Once corrected, funding increased due to inflation.

**FY2026 plans — current year.** - Continue to modernize SIGINT systems used by the MQ-9A and other platforms. Additional details are classified.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
