Unmanned Undersea Systems

Redefining operational readiness and threat response with undersea autonomy.

Safeguarding Critical Undersea Assets

Unmanned undersea systems play a critical role in modern maritime security by enabling persistent subsea surveillance and intelligence gathering. Our next-generation vehicles operate autonomously or with remote guidance, providing real-time data collection and threat assessment in environments that are often inaccessible or too hazardous for human operators. By enhancing situational awareness and supporting strategic decision-making, our unmanned undersea systems are essential tools for detecting, tracking, and analyzing potential subsea threats—safeguarding national interests and maintaining global maritime stability.

The VANGUARD unmanned underwater vehicle UUV and Freedom AUV perform underwater asset surveillance

Built for Performance in Harsh Environments

Operating in the subsea domain presents a unique set of challenges—from extreme pressure, corrosive saltwater, and near-zero visibility to fluctuating currents and unpredictable terrain. These demanding conditions require unmanned systems that are not only durable but also highly adaptable and mission ready. Designed with modularity in mind, our large and small unmanned undersea vehicles offer capabilities for rapid payload integration and streamlined deployment in the most unforgiving environments.

Key Features

With a focus on operational flexibility and mission endurance, these systems are built to support complex surveillance and intelligence missions where conventional assets cannot operate.

Pressure-Tolerant Electronics

Prevent flooding failures at depth and reduce vehicle weight

Hovering and Vertical Navigation

Improve inspection accuracy with precise, stable maneuvering

Advanced Onboard Sensors

Enhance environmental monitoring and threat detection

Modular Payload Bays

Enable quick integration and reconfiguration of mission-specific equipment

Designed for Modularity, Upgradability, and Mission Versatility

Our unmanned undersea vehicles are built around a modular architecture featuring line-replaceable units (LRUs), allowing for rapid technology insertions, feature upgrades, and streamlined maintenance with minimal downtime. This modularity supports a wide range of mission profiles and system enhancements, from hardware swaps to advanced software upgrades.

Payload modules on the VANGUARD unmanned underwater vehicle UUV are interchangeable and can be customized and configured to meet varied operational needs

Full-Spectrum Undersea Operations

Our scalable, unmanned systems capabilities ensure unmanned platforms remain mission-ready, adaptable, and effective across the full spectrum of undersea operations—from reconnaissance and threat detection to intervention and recovery.
