The problem we are solving is simple: U.S. launch infrastructure is insufficient for the aims of the modern space economy. Existing launch sites were built for the Apollo era, and an aging network of coastal facilities is now facing significant limitations. These fixed locations are increasingly congested, constrained by surrounding communities and environmental regulations, and vulnerable to weather disruptions and security risks. As the demand for launch services grows, these bottlenecks threaten to stall the progress of the space economy at a time when momentum is critical. Our Gateway-S concept is a purpose-built semisubmersible platform designed to resolve this constraint by enabling cost-effective and efficient launches offshore. The current design is tuned for the launch of a smaller (40-80 foot) rocket vehicle, offering a ~50% reduction in capital cost while improving speed and stability performance over traditional barge designs. Once proof of concept is established with a smaller rocket, our long-term vision is a network of staging, launch, and recovery infrastructure that allows launches to occur entirely offshore for an array of rocket sizes.

• Since incorporating in January 2025, we've had strong traction across a variety of areas:
• Signed MOUs with multiple launch companies, including a co-design agreement with Firefly Aerospace and a Gulf Launch exploration MOU with Vaya Space.
• Received design Approval In Principle from American Bureau of Shipping, the first to be granted under their offshore spaceport guidelines.
• Successfully completed an initial wave tank hydrodynamic study with MIT's Sea Grant laboratory.
