The Navy's UUV Fleet
Cannot Coordinate

The United States Navy operates some of the most capable autonomous underwater vehicles ever built. Boeing Orca. Anduril Dive-LD. Bluefin-21. Snakehead. Razorback. Each is a capable platform. None of them can work together in a coordinated swarm.

This is not a hardware problem. It is a software problem — the absence of a distributed coordination protocol designed for the acoustic underwater environment. Every manufacturer runs a closed, proprietary stack. The longer this continues, the more expensive the integration problem becomes.

SENTINEL is the coordination layer the UUV ecosystem needs before that fragmentation becomes permanent.

ERR-01
No Multi-Vendor Swarms
Mixed Orca/Dive-LD/Bluefin deployments are operationally impossible. Operators accept lock-in or buy redundant incompatible systems.
ERR-02
Surface Ship Dependency
Current coordination requires a surface ship in contested environments — the highest-value target in the area. Operationally unacceptable.
ERR-03
Human-in-the-Loop Bottleneck
Acoustic comms run at 1-10 kbps with 3-7 second propagation delays. Centralized command approval fails under these physics constraints.
ERR-04
Single Points of Failure
Lose one vehicle and missions degrade catastrophically. No existing system self-heals coverage gaps or reroutes autonomously.

What SENTINEL Does

CAP-01 // COORDINATION
Vendor-Agnostic Protocol
Runs on any AUV with an acoustic modem. Coordinates Boeing, Anduril, and Bluefin platforms in a single swarm. No hardware modification required.
→ STANAG-aligned acoustic protocol
CAP-02 // NAVIGATION
GPS-Denied Localization
Vehicles continuously range each other acoustically. Cooperative trilateration corrects INS drift without GPS, surface ships, or transponder arrays.
→ 20% INS error reduction at 12hr mission
CAP-03 // CONSENSUS
Distributed Decisions
No central controller. Modified Raft consensus protocol adapted for acoustic networks. Swarm-wide abort achieved with 32% packet loss.
→ Consensus at 68% acoustic delivery rate
CAP-04 // STEALTH
Acoustic Shadow Routing
Vehicles autonomously compute and navigate to thermocline acoustic shadow zones. No human specifies this — the swarm optimizes its own stealth profile.
→ 70% detection reduction below thermocline
CAP-05 // RESILIENCE
Self-Healing Coverage
When vehicles are lost or compromised, SENTINEL detects coverage gaps and autonomously reroutes remaining vehicles. Validated at 75% fleet attrition.
→ Mission continues at 75% vehicle loss
CAP-06 // AWARENESS
Surface + Subsea Fusion
Live AIS vessel tracking, shadow fleet detection, and subsea magnetic/acoustic contact fusion into a unified intelligence picture shared acoustically.
→ Pre-mission threat map from AIS analysis

Built on Real Physics.
Validated Performance.

The SENTINEL engine is written in Rust — chosen for memory safety, real-time performance, and suitability for safety-critical autonomous systems. Acoustic propagation is modeled using Bellhop ray-tracing, the same tool used by Navy acoustic researchers.

US NAVY VETERAN
LOGSU-1

Naval veteran with logistics experience at LOGSU-1, understanding firsthand how systems get from procurement to operational deployment — and where they fail. Built SENTINEL's simulation engine, acoustic communications protocol, distributed consensus algorithm, and machine learning coordination layer from first principles.

The vendor lock-in problem isn't theoretical. It's a real operational constraint that anyone who has worked with multi-vendor systems in the Navy understands immediately. SENTINEL exists because the coordination layer should have been built years ago.
