By “open-architecture” we mean open/modular both for hardware reconfiguration as well adhering to open software standards for plug-and-play sensors/comms/nav/autonomy stacks. Said AUV platform should be two-person portable, and support operations for up to 24 hours.

We expect the open architecture to allow for a wide variety of sensors and payloads, enabling collaborative sensing and other commercial and defense applications across a multifunctional fleet of vehicles.

Description: The maritime operational environment requires autonomous underwater platforms capable of executing a wide array of defense, commercial, and scientific missions without the constraints of traditional, proprietary architectures. Current systems often face limitations in payload flexibility, prolonged downtime for repairs, and challenges in multi-platform collaboration.

This topic seeks the development of an AUV ecosystem that reduces mechanical complexity while maintaining strict control across the water column, including fixed-depth stationkeeping. Vehicle stability and predictable/reliable performance is key to getting usable data off the platform. To achieve operational agility at scale, the proposed platform must support an end-to-end mission lifecycle approach.

This involves AI-driven mission optimization to configure the ideal vehicle build, physics-based pre-deployment simulation to mitigate operational risk, and automated data offloading to enable continuous fleet-wide learning.

The architecture must demonstrate the following critical capabilities: Capability Area Technical Requirements Modular Architecture & Rapid Reconfiguration Provide a mission-configurable, flooded-hull architecture that supports rapid-swap payloads and upgradeable subsystems.

Must enable upgrades or repairs in hours or days, enabling rapid adaptation and customization for enhanced performance, functionality and reliability while minimizing downtime and reliance on specialized tooling in the field. Multi-Vehicle Collaboration Provide software hooks to support task allocation across heterogeneous vehicles.

The system should support rapid and persistent vehicle tasking in a manner that is not burdensome to an end user. Resilient Communication Integrate a seamless multimodal mesh communications network capable of linking acoustic, radio frequency (RF), cellular, and satellite channels to support collaborative distributed fleets.

Advanced Autonomy & Software Ecosystem Utilize an integrated software ecosystem (encompassing objective-based mission planning, command-and-control, and centralized data analytics hubs) to connect mission design, deployment, and data exploitation. Power & Propulsion Innovation Accommodate advanced, scalable hardware integrations.

The platform should also support software-optimized, customizable propulsion systems tailored to specific hydrodynamic profiles and endurance targets.

Acoustic and Hydrodynamic Signature Control Incorporate advanced signature management techniques to minimize acoustic radiated noise and hydrodynamic wake profiles Modular Architecture & Rapid Reconfiguration Provide a mission-configurable, flooded-hull architecture that supports rapid-swap payloads and upgradeable subsystems.

Acoustic and Hydrodynamic Signature Control Incorporate advanced signature management techniques to minimize acoustic radiated noise and hydrodynamic wake profiles This topic is soliciting Direct to Phase II (DP2) proposals only.

Proposals will be considered for DP2 funding based on documented ability of the proposing team to build open-architecture autonomous underwater vehicle (AUV) platform that enables rapid payload adaptation, scalable fleet deployment, advanced multi-vehicle collaboration, range, speed and stealth, and resilient autonomous navigation.

Proposals must clearly demonstrate that the proposed technology can satisfy the feasibility criteria in the following domains: Vehicle Dynamics and Hydrodynamic Modeling: Data demonstrating the capability to model the propulsion performance, vehicle dynamics, and associated hydrodynamic signatures of individual underwater platforms.

Acoustic Characterization and Localization: Data demonstrating the ability to characterize, localize, and estimate the acoustic signatures of individual platforms or multi-vehicle formations. Formation Stability and Communication Resilience: Analytical or algorithmic proof supporting stable formation control, ensuring coordinated maneuverability and consensus under degraded communication environments or platform performance.

The purpose of Phase II is to develop and demonstrate a functional, in-water prototype of the open-architecture AUV. Performers will validate the rapid reconfiguration capabilities by successfully swapping payload housings and integrating new sensor packages within the targeted timeframe without specialized tools.

Performers will conduct at-sea testing of the multimodal mesh communications and demonstrate dynamic, multi-vehicle collaborative sensing and autonomous navigation in a simulated operational environment. Month 2: Deliver hardware/software interface standards for the proposed modular flooded-hull AUV.

Report must establish baseline specifications for the multimodal mesh network, external solid-state batteries, and AI-driven mission planning ecosystem. Month 6: Critical Design Review (CDR) of the design of the system architecture. CDR must include how to validate the physical and software interfaces for rapid payload adaptation.

Month 10: Demonstrate the physics-based pre-deployment simulation environment. Integrate the core autonomy stack, including objective-based mission planning and market-based task allocation algorithms for multi-vehicle workloads. Month 14: Complete the build of the first functional AUV.

This must include a physical demonstration validating that payload housings can be swapped within the target timeframe within 24 hours without specialized tooling. Month 18: Integrate and demonstrate the multimodal communications mesh (acoustic, RF, cellular, SATCOM). Conduct initial in-water testing of a single AUV to validate fixed-depth stationkeeping, propulsion endurance, and network connectivity.

Month 22: Demonstrate a heterogeneous fleet of AUVs in a simulated operational environment. Demonstrate dynamic retasking, deconfliction, collaborative sensing, and automated data offloading across the mesh network. Month 24: Finalize the data analytics exploitation from the at-sea test.

Deliver a finalized Phase III transition plan detailing scaling for fleet-wide deployment and integration into DoW/commercial enterprise architectures. Phase III dual use applications Phase III will be oriented to scaling the system for fleet-wide deployment and integration into broad defense and commercial enterprise architectures.

The goal of Phase III will be to transition the platform into a commercially viable product capable of rapid payload integration for advanced undersea systems programs, facilitating accelerated experimentation and operational transition for end-users. resilience. https://www.
