THE FUTURE OF SHIPPING

Internationally competitive, American-built cargo ships.

Fleetzero builds with modular designs, advanced manufacturing, and autonomous propulsion to fundamentally change the economics of shipping.

BUILD WITH FLEETZERO

SHIPPING TECHNOLOGY

HAS NOT CHANGED.

UNTIL NOW.

Traditional building methods are bespoke and labor intensive.

Fleetzero has studied, rebuilt, and commissioned vessels.

We’ve saved the best from the past, and found a better way forward.

Built in America. Cost competitive globally.

Modules built off-site. Repeatable designs. Robotic manufacturing. Less material.

Fleetzero is bringing the efficiency and scalability of modern manufacturing to shipbuilding.

80% LOWER COST VS. TODAY

Designed from the inside out. Built to move cargo better.

  • Industrial robotic arm welding a metal component on a perforated workbench inside a fabrication facility.

    Factory-Built vs. Shipyard-Built

    Standardized, modular construction designed to make shipbuilding faster, more repeatable, and more scalable. Modules assembled on-site.

  • Interior of a high-density battery room

    Lower Operating Costs

    Less maintenance, simplified systems, and efficient operations designed to lower total ownership costs.

  • Fleetzero oil tanker sailing across the ocean at sunset

    Smarter Vessel Design

    Purpose-built hulls and vessel architecture that maximize cargo capacity while reducing materials and complexity.

  • Leviathan energy storage system

    Vertically Integrated Propulsion & Intelligence

    Electric propulsion and autonomy-ready systems designed together from the beginning.

AUTONOMOUS INTELLIGENCE.

BUILT BY MARINERS.

Powered by OctoDrive, Fleetzero integrates autonomous navigation and remote operations technology designed around the needs of real mariners and commercial fleets.

EXPLORE AUTONOMY

ELECTRIFICATION

Traditional propulsion requires constant maintenance. Fleetzero’s Leviathan propulsion system enables long-range autonomy.

UNLOCKS LONG-RANGE AUTONOMY
