Poseidon Aero
Poseidon Aerospace builds full-size autonomous cargo aircraft for resilient logistics.
The product
Poseidon Aerospace is developing Egret, an unmanned short-takeoff-and-landing cargo aircraft, and Heron, an unmanned seaplane. Both are designed to carry roughly two tons of cargo over more than 1,000 nautical miles, operating autonomously or under remote control from conventional runways, water, and austere locations.
The thesis
Its aircraft could make air freight more affordable and resilient by serving remote communities, maritime routes, and contested logistics environments without onboard pilots or extensive runway infrastructure.
How it runs
Vertically integrated developer and planned operator of purpose-built full-size autonomous cargo aircraft, with engineering in San Francisco and production capacity in Brunswick, Maine.
How it earns
Plans to retain and operate its unmanned aircraft as a regional commercial cargo service rather than sell aircraft to incumbent carriers, implying transport-service revenue for moving freight. It also pursues commercial- and defense-logistics customer programs; pricing and contract structures are not disclosed.
Why it wins
Designs unmanned aircraft around cost per flight-ton-mile, cargo volume, and operations from water or austere runways instead of retrofitting autonomy onto aging crewed aircraft.
