Small UUVs
REMUS-class · man-portable
- Hours of endurance
- Tens of kilograms of payload
- Constrained to a single mission package
Autarch Systems LLC
Heavy-class unmanned maritime vehicles, built for the missions in between.
Today's undersea fleet is split between man-portable UUVs and the handful of XL-class programs that take a decade to field. Autarch Systems is building the missing middle — a heavy-class unmanned underwater vehicle designed from the keel up for affordability, producibility, and mission flexibility.
The capability gap
Two classes. One order-of-magnitude void between them.
XL UUVs
Echo Voyager-class · program-of-record
- Months of endurance
- Tons of payload
- Composite hulls, cost-plus economics, multi-year fielding
Incumbents can't close this gap because the design choices that earn them the XL contract — exotic hull materials, bespoke pressure vessels, integrated payloads — are the same choices that put the platform out of reach for mid-tier programs, allied buyers, and attritable concepts of operation. Autarch starts from a different constraint set.
Engineering approach
Designed for manufacturability before performance.
Commercially available materials
The primary structure is built from commercially available, standards-graded materials with mature welding and inspection regimes. No exotic composite layup, no bespoke filament-winding line.
Modular internals
Mission energy, payload, and propulsion are independently serviceable modules. Field-replaceable battery packs. Payload bays sized to host third-party capability without a re-qualification of the host vehicle.
Hybrid energy architecture
Battery for submerged-leg endurance. Snorkel-fed charging for total mission range. Concurrent cruise-and-charge — not a trickle-charge afterthought.
Container-packable baseline
The baseline hull is sized to ship four units in a standard 20' ISO container. Logistics-friendly from day one. Larger range-first variants are explicitly off-container by customer request.
Requirements-driven
Every published capability traces back to an enumerated, versioned requirement with a decision log behind it. We can show our work, and we can show how it would change under your mission constraints.
Generic capability platform
Eidolon is a host vehicle, not a single-mission payload truck. We integrate with third-party payload vendors rather than competing with them.
Program fit
Built for the contracting paths the Department actually uses.
SBIR / STTR
Phase I/II topics across DoN, USSOCOM, USAF, and DHS.
DIU / AFWERX / SOFWERX
Commercial-solutions-opening and prototype OTA pathways.
Prime teaming
Subsystem and platform integration with established maritime primes.
NDAA-compliant supply chain
Design intent and BOM curation for §889 / covered-vendor exclusions.
