The Spaceport Company is America’s leading offshore launch provider
…built to solve one of the space industry’s biggest bottlenecks: limited access to launch pads. We operate the nation’s only commercial launch pad ship and are the exclusive supplier of Tri-Sub, a proven semi-submersible offshore launch platform designed for rapid deployment anywhere at sea.
Since our founding, The Spaceport Company has completed ten launches at sea and established commercial offshore missile test ranges in both the Gulf of America and the Atlantic Ocean — giving government and commercial customers a flexible alternative to overcrowded, fixed-location spaceports. Our customer base includes the Department of War (through multiple active contracts), Lockheed Martin, X-Bow Systems, and a growing list of defense and aerospace partners.
Vertical integration sets The Spaceport Company apart: in-house design, engineering, fabrication, and regulatory compliance teams, all under one roof. That means we control the full timeline of offshore launch operations — from concept to countdown.
Our marine assets are available now for offshore missile testing and orbital launch missions. If you need a faster, more flexible path to launch, we’re ready today.
Our team is composed of launch system and maritime experts
with a proven track record of getting it done.
