Boom Supersonic's Superpower Data-Center Turbine Shares About 80% of Hardware With Symphony Jet Engine
Why It MattersA ground-based turbine business gives a supersonic airliner programme a revenue line and real engine operating data before any passenger aircraft exists, though flight certification remains separate.
Boom Supersonic is developing Superpower, a 42-megawatt natural-gas turbine for AI data centers that the company says shares approximately 80 percent of its hardware with Symphony, the clean-sheet turbofan intended to power its planned Overture airliner. Superpower replaces the aircraft fan and nacelle with equipment to generate electricity. Boom says the trailer-mounted unit can maintain full output in temperatures up to 110 degrees and operate without water, and can be delivered in four road-transportable modules.
AI-infrastructure company Crusoe ordered 29 units representing 1.21 gigawatts of capacity. Boom announced a Superpower backlog exceeding $1.25 billion and a separate $300 million funding round in December 2025. First customer deliveries are planned for 2027. Boom says operating data from Superpower on wear, heat, vibration, maintenance and component life in the shared core will inform Symphony's development and certification, though ground operation cannot replace the flight tests and aviation certification required for a passenger engine.
Overture is a proposed 60-to-80-passenger airliner designed to cruise at Mach 1.7 over water; Boom says it could cut a New York-to-London trip to about three hours and 40 minutes. The aircraft has not been built, certified or placed into passenger service. Boom's XB-1 demonstrator flew supersonic over California's Mojave Desert in January 2025, reaching Mach 1.122. Boom has completed its Overture Superfactory in Greensboro, North Carolina, and selected StandardAero's San Antonio facility for final assembly and testing of production Symphony engines.
NASA's X-59 flew faster than sound for the first time in June 2026, and the Federal Aviation Administration has proposed replacing the blanket ban on routine civil supersonic flight over land with a performance-based noise rule. That rule remains a proposal. Open risks include unproven operating economics, airline orders that are not delivered aircraft, and the environmental impact of Superpower burning natural gas and Overture's reliance on sustainable aviation fuel.
