The future of global trade moves beneath the surface
Supporting global supply chains by offering autonomous submarine cargo solutions as an alternative to air and traditional shipping.
Surface shipping is broken
90% of global trade moves by sea. But surface shipping faces escalating risks that threaten the reliability of international commerce.
Piracy & Security Threats
Over $12B in cargo is lost to piracy annually. Surface vessels remain vulnerable across high-risk maritime corridors.
Weather Disruptions
Extreme weather events cause an average of 17 days of delays per transoceanic shipment, driving up costs and uncertainty.
Canal Bottlenecks
The Suez and Panama Canals handle 20% of global trade. Closures and congestion create cascading supply chain failures.
Rising Insurance Costs
Marine insurance premiums have increased 340% in high-risk zones since 2019. The industry needs a fundamentally different approach.
Three steps to subsurface logistics
A seamless, fully automated process from origin to destination.
Load
Cargo is loaded at our proprietary SubPort terminals using automated gantry systems. Containers are pressure-sealed and secured in standardized submarine cargo bays.
Submerge
SubFreighters dive to optimal cruising depth and navigate via our proprietary DeepRoute AI. Zero weather impact. Zero piracy risk. Zero canal dependency.
Deliver
SubFreighters surface at the destination SubPort. Cargo is automatically offloaded and cleared through our integrated customs pre-processing pipeline.
Purpose-built for the deep
Three vessel classes engineered for every distance and cargo requirement.

Superior by every metric
A head-to-head comparison across the dimensions that matter most to global logistics operations.
| Metric | SubShipping | Traditional Shipping | Air Freight |
|---|---|---|---|
| Cost per TEU | $1,200 | $1,800 | $5,400 |
| Transit Time (Shanghai–Rotterdam) | 18 days | 30 days | 3 days |
| Weather Dependency | None | High | Moderate |
| Piracy Risk | Zero | Significant | Low |
| Canal Dependency | None | Critical | None |
| CO₂ per TEU-km | 8g | 16g | 670g |
| Crew Risk | Zero | 22 avg crew | 2–4 crew |
Active submarine corridors
Our subsurface routes bypass every major bottleneck, delivering cargo through the world's oceans on direct, canal-independent paths.
Operating within the rules
We work alongside international commercial ports and all branches of the navy to guarantee safe transit from origin to destination, fully respecting the sovereign rights of every state.
Port Compliance
Full coordination with international commercial port authorities at every point of entry and exit.
Naval Coordination
Active collaboration with naval forces worldwide to ensure safe, transparent subsurface transit corridors.
Sovereign Respect
All routes are planned and operated in full compliance with the sovereign rights of every coastal and territorial state.
Trusted by forward-thinking logistics leaders
What our partners say
SubShipping has fundamentally changed how we think about intercontinental logistics. The elimination of weather-related delays alone has saved us an estimated $14M in Q3.

Chief Supply Chain Officer, NordicCold Logistics
When the Suez blockage hit in 2025, our competitors scrambled. Our SubShipping-routed cargo arrived on schedule. That's when we knew this was the future of freight.

The insurance savings are real. Our marine premium dropped 62% on SubShipping-serviced routes. Zero piracy exposure, zero weather risk — underwriters love it.
