Boom Supersonic is developing a novel gas turbine, named Superpower, designed to supply power to AI data centers. This initiative complements the company's ambitious plan to produce the Mach 1.7 Overture supersonic airliner later this decade. The Superpower engine, fueled by natural gas, has been ordered by Crusoe, a Texas-based energy firm constructing the Stargate AI data center in Abilene. Crusoe has placed an initial order for 29 units, each capable of generating 42 megawatts under high-temperature conditions.
In parallel, Boom has announced securing $300 million in funding, which alongside the gas turbine deal, aims to support the completion of the Symphony engine and the initial Overture aircraft. The funds will also expedite engine testing by increasing test hours for the core. The funding round was led by Darsana Capital Partners, with participation from Altimeter Capital, ARK Invest, Bessemer Venture Partners, Robinhood Ventures, and Y Combinator. CEO Blake Scholl commented that this would be the final capital required to produce the turbine and finance the airplane program.
Origins and Development of the Gas Turbine
The project was prompted by discussions between Boom's leadership and industry figures like Sam Altman, CEO of OpenAI, emphasizing the need for substantial electricity supplies for AI operations. Abhir Adhate, Boom’s engine performance lead, explained modifications to adapt Symphony's high-pressure core for industrial applications, including the addition of a low-pressure spool and a free power turbine to generate electricity from exhaust gases.
The Superpower engine features a dual-fuel combustor capable of burning natural gas and diesel, with plans for annual production exceeding 4 gigawatts by 2030, driven by current orders and market demand. The development supports the main Symphony engine, with testing scheduled to begin by mid-2026. The first fully integrated 42-megawatt unit is expected to be ready by the end of next year.
This project is seen as an accelerant for Boom's broader technology demonstration efforts, providing extensive ground testing experience that will support certification. The company anticipates that the reliability data collected during testing will bolster confidence with regulators and future customers, establishing the Superpower as a key component of Boom’s technological portfolio.
Despite potential concerns about diversifying into gas turbines, Boom’s leadership views the project as a strategic enhancement that will support initial production and further validation of the core engine design. This approach aims to ensure long-term sustainable growth for Boom’s aerospace and energy ventures.
