Corridian raises $38M seed to build ultra-large autonomous underwater vehicles

Corridian, a New England defense startup building ultra-large autonomous underwater vehicles (AUVs), came out of stealth on Nov. 3 with a $38 million seed round led by Point72 Ventures. Balerion Space Ventures, Harpoon Ventures, DCVC and Marlinspike also invested.
The company says its uncrewed subs are designed to carry ISO-standard containerized payloads thousands of nautical miles, with initial uses in payload and "effects" delivery, surveillance and "contested logistics." Its founders previously led undersea autonomy programs at General Dynamics. The money goes to the flagship vehicle, an R&D facility and hiring.
Why it matters
No vehicle has been shown yet: Corridian plans to unveil it in 2027, and co-founder Mike Guay declined to share specs or how it would launch, Axios reports. Asked about payloads, he said the platform carries "whatever payloads our customers choose."
