Andreman, a Los Angeles-based startup, has deployed its PEARL sonobuoy system to the U.S. Navy to address persistent undersea detection and surveillance gaps. The system provides six-month deployment duration with real-time satellite-linked acoustic data processing.
What's happening
- PEARL sonobuoys are deployed from boats or ships and float on the ocean surface with hydrophones monitoring ocean depths for detection, tracking, and classification of underwater targets.
- The buoys measure three feet by three feet, weigh about 70 pounds, and operate for a design life of six months or more using solar-charged batteries with satellite uplinks.
- OBSIDIAN software ingests real-time acoustic data, processes spectrograms, performs beam forming, and conducts multi-buoy sensor fusion for actionable intelligence.
- Andreman operates as a Contractor Owned, Contractor Operated managed sensing service, meaning the Navy buys persistent coverage and intelligence rather than owning and maintaining the system.
Why it matters
- PEARL fills a capability gap between short-duration aircraft sonobuoys and fixed harbor defense systems, providing persistent wide-area search and surveillance that Vice Admiral Richard E. Seif identified as a top submarine force priority.
- The system addresses three Navy mission sets: anti-submarine warfare, counter-UUV operations, and counter-narcotics trafficking against low-radar-signature vessels.
- Distributed, scalable, and attritable buoy networks reduce the complexity and maintenance burden compared to traditional fixed or aircraft-deployed acoustic monitoring systems.
Going deeper
- Cernosek, the CEO and co-founder, is a former SpaceX and Sierra Space engineer who chose passive sonar and software-defined hardware architectures over saturated UAV and UUV markets.
- The PEARL design is semi-attritable and cost-effective per area of coverage, allowing the Navy to deploy buoys at scale across choke points and strategic locations.
The intrigue
- Andreman acknowledges Navy contracts but Cernosek declined to discuss customer details, leaving unclear the scale of deployment, procurement commitments, or whether additional service branches are adopting the system.
