**R-2A activity** of project 0000 — Undersea Warfare Applied Res  
**Program element:** 0602747N — Undersea Warfare Applied Res  
**Component:** U.S. Navy · **Budget Activity:** 2  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $18.8M in FY2027, 36% of project 0000, down 20% 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.** -Continue Active Sonar development of advanced signal and information processing for high duty cycle active sonar. Further development of concepts for next-generation active sonar system automation, leveraging the latest advances in machine learning and artificial intelligence. -Continue non-acoustic, orthogonal concepts that complement and augment active sonar concepts. -Continue Sensors applied research in improved sensor technology to include both passive and active acoustic and optical sensing to extend the capabilities of platform-based systems as well as innovative sensor technology for off-board and rapidly deployable systems. -Continue Signal Processing development of advanced signal and information processing for high duty cycle active sonar. -Continue development of technologies and techniques for exploiting structural acoustic vulnerabilities of adversary undersea platforms conducting an at sea trial. -Continue efforts that will lead to optimized sensing and behaviors by adapting in dynamic and uncertain environments; cooperative vehicle autonomy with increased endurance; data exfiltration and networking to expand reach; next generation sensors (acoustic and non-acoustic); adaptive, autonomous technologies to detect, classify, and track underwater mobile threats. -Continue development of technologies and signal processing, verified through sea trials that exploit the structural acoustics of undersea vehicles and structures.

**FY2026 to FY2027 change.** Decrease in funding from FY2026 to FY2027 is due to decreased research efforts across multiple areas including active sonar development, sensor applied research, and signal processing development.

## Before the request year

**FY2026 plans — current year.** -Continue Active Sonar development of advanced signal and information processing for high duty cycle active sonar. Further development of concepts for next-generation active sonar system automation, leveraging the latest advances in machine learning and artificial intelligence. - Continue non-acoustic, orthogonal concepts that complement and augment active sonar concepts. -Continue Sensors applied research in improved sensor technology to include both passive and active acoustic and optical sensing to extend the capabilities of platform-based systems as well as innovative sensor technology for off-board and rapidly deployable systems. -Continue Signal Processing development of advanced signal and information processing for high duty cycle active sonar. -Continue development of technologies and techniques for exploiting structural acoustic vulnerabilities of adversary undersea platforms conducting an at sea trial. -Continue efforts that will lead to optimized sensing and behaviors by adapting in dynamic and uncertain environments; cooperative vehicle autonomy with increased endurance; data exfiltration and networking to expand reach; next generation sensors (acoustic and non-acoustic); adaptive, autonomous technologies to detect, classify, and track underwater mobile threats. -Continue development of technologies and signal processing, verified through sea trials that exploit the structural acoustics of undersea vehicles and structures.
