At ThayerMahan, we understand that economic prosperity and national security depend on a secure maritime domain. Our Undersea Surveillance Solutions deliver scalable, autonomous, and persistent monitoring capabilities that extend your surveillance reach across vast oceans, strategic chokepoints, and critical ports.
Whether supporting defense operations, law enforcement, or commercial infrastructure protection, our systems provide the real-time acoustic intelligence needed to detect threats, maintain strategic advantage, and ensure operational continuity.
“What we are seeing here is the future of our Navy... It makes sense to invest in Outpost to meet the growing challenges of undersea warfare and ensure a strong national defense.”
Senator Richard Blumenthal

Mission-Aligned Capabilities
Persistent Acoustic Surveillance
Our unmanned systems operate autonomously for months to years, powered by renewable energy sources. They deliver continuous monitoring without the need for frequent maintenance or human intervention.
Advanced Detection & Classification
Using Gen 4 beamforming arrays, our systems detect, classify, and localize underwater contacts—including submarines, UUVs, warships, and reconnaissance vessels—with unmatched precision.
Real-Time Intelligence
Secure satellite communications and onboard signal processing ensure that actionable data reaches operators and analysts in real time, enabling faster decision-making and threat response.
“Autonomous, high-quality, connected, persistent sensors at an affordable price is fundamental. I have been studying this situation my entire adult life, not only studying but operating in this environment. Outpost provides all of those qualities, it is exactly the type of sensor we need.”
Admiral John Richardson (retired)
Former Chief of Naval Operations

Beamforming Arrays: A Leap Forward in Acoustic Surveillance
Our linear acoustic arrays represent the pinnacle of underwater listening technology:
- Directional Listening: Pinpoints sound origin for accurate localization
- Noise Rejection: Filters out ship, wind, and marine life interference
- High Sensitivity: Detects faint signals with up to 10x the range of traditional hydrophones
- Real-World Impact: In one study, our arrays detected over 6,800 whale vocalizations in 90 minutes—compared to just 599 by a single hydrophone
These capabilities support both national defense and environmental compliance, including monitoring for endangered species like the North Atlantic Right Whale.
