Seagate Space develops Gateway-S, a semi‑submersible, dynamically positioned (DP-2) offshore launch platform with a modular architecture intended to support different small-to-medium launch vehicles. The platform is designed for rockets up to 24 meters in length and aims to enable higher cadence offshore launches, with the company targeting first missions in 2027. Since its January 2025 founding in St. Petersburg, Florida, Seagate Space has signed MOUs with Firefly Aerospace, Oceaneering International, and Lockheed Martin to distribute engineering responsibilities and mission concepts. The company conducted hydrodynamic scale-model tests at MIT Sea Grant Hydrodynamics Laboratory and in December 2025 received an Approval in Principle from the American Bureau of Shipping under new standards for offshore spaceports. Financially, Seagate closed an oversubscribed $1.5M pre-seed round with New World Angels and DraperU Ventures and announced an additional, undisclosed strategic investment from Space Florida. The firm has not disclosed full project budgets or a valuation.
