Tri-Sub
A semi-submersible offshore platform that the company sells as a mobile sea-based launch pad and ground station. The company calls the design proven and says it is the only supplier.
Why it matters
A stable floating pad could let larger rockets launch from the ocean, adding launch capacity without building new coastal spaceports.
How the technology works
A semi-submersible rides low in the water for stability, giving a steadier pad than a ship deck. The company pairs launch pad and ground station functions on one platform.
