As utilities struggle to keep up with energy-hungry data centers, Boom Supersonic is pitching a radical idea: park ground-based versions of its supersonic engine next to server farms and use them as compact gas plants to feed the AI boom.
A 42 MW “plane engine” repurposed for the ground
Boom Supersonic, better known for its Overture supersonic airliner project, has unveiled “Superpower”, a 42 megawatt gas turbine designed specifically to supply electricity to high-performance computing and AI data centers.
The machine borrows its core from Symphony, the engine Boom is developing for long-range supersonic flight. Instead of pushing an aircraft through the sky, the adapted turbine will spin a generator on the ground and feed power straight into racks of servers.
Superpower is a 42 MW gas turbine derived from a supersonic jet engine core and re-engineered as a compact on-site power plant for AI data centers.
The first major customer is US firm Crusoe, which specialises in high-performance computing. It has ordered 29 turbines, representing about 1.21 gigawatts of planned capacity. The contract is valued at roughly $1.25 billion, a substantial bet on technology that has not yet left the test stand.
Boom says Superpower keeps the crucial characteristics of a flight engine: high operating temperature, dense power output and advanced monitoring. But the package has been ruggedised for industrial use, designed to run continuously on the ground instead of at altitude.
When AI outgrows the grid
Grid bottlenecks meet data center deadlines
Across the United States, demand for new data centers is colliding with a power system that was never designed for an AI arms race. In some regions, transmission lines are saturated and grid connections for new facilities take years to approve and build.
Developers now face a choice: wait for utilities to reinforce networks or bring their own generation on site. Crusoe is opting for the latter, aiming to bypass grid bottlenecks by installing its own gas turbines right next to its hardware.
That is where Boom wants Superpower to fit. The unit is ultra‑compact compared with conventional power plant turbines, which suits land-constrained data campuses where every square metre has a cost.

By producing electricity on site, data centers can grow at AI speed instead of waiting on multi-year grid upgrades and new transmission lines.
Designed for scorching temperatures and dry regions
One of Boom’s central claims is resilience in high heat. Conventional gas turbines can lose up to 30% of their output when ambient temperatures soar, exactly when grids are already stressed by air conditioning and heatwaves.
Superpower, according to the company, maintains its full 42 MW even at 43°C (around 110°F), and does so without using water for cooling. That matters for regions like the American Southwest, where new data centers often rise in arid areas with limited water rights.
- Rated power: 42 MW per turbine
- Cooling: Dry operation, no process water required
- High-heat performance: Full output maintained at 43°C ambient
- Main use case: On-site power for AI and high-performance computing data centers
Removing water from the equation cuts both operational risk and political friction in drought‑prone states, where large industrial consumers already face scrutiny over their impact on local supplies.
How a supersonic engine becomes a power plant
From Symphony to Superpower
Technically, Superpower keeps the “hot core” of Symphony: the compressor, combustor and high-pressure turbine section designed for supersonic endurance. The company adds a power turbine and generator stage, reconfiguring the engine to produce electricity instead of thrust.
The unit also inherits a sophisticated online monitoring system first used on Boom’s XB‑1 demonstrator jet. Every hour of operation generates data on material behaviour, thermal cycles and performance trends.
Each running hour of a Superpower turbine doubles as a live test for the materials and design of Boom’s future supersonic flight engine.
This creates a feedback loop. Power customers get a turbine tuned for reliability, while Boom gathers huge data sets that help validate Symphony for future commercial flights. The industrial energy product effectively finances and proves the aviation programme.
Vertical integration as a survival strategy
Boom has already raised an additional $300 million from investors including Darsana Capital, Altimeter, ARK Invest and others. Part of that funding goes into building out an energy business large enough to sustain its aerospace ambitions.
Chief executive Blake Scholl frames the move as a deliberate pivot toward vertical integration: design the engines, build the turbines, operate the factories and keep control of the whole chain. For an aerospace start‑up, that is an aggressive stance, but one that aligns with the pace set by big tech buyers of AI compute.

Ambitious timelines and industrial scale
Boom targets a first complete Superpower prototype by the end of 2026. Initial deliveries to Crusoe are planned for 2027, assuming testing and certification stay on track.
Behind that schedule sits a manufacturing blueprint that looks more like an energy major than a start-up. The company intends to build a dedicated factory for industrial turbines, with an initial annual output capacity of 2 GW. The goal is to ramp that to 4 GW of turbines produced per year by 2030.
| Milestone | Target date |
|---|---|
| First full Superpower prototype | End of 2026 |
| Start of customer deliveries | 2027 |
| Initial factory capacity | 2 GW per year |
| Planned annual capacity by 2030 | 4 GW per year |
Production equipment for the plant has reportedly already been ordered, a sign that Boom expects demand from data center developers to materialise quickly.
Data centers and the new energy land rush
AI’s electricity appetite keeps rising
The Boom–Crusoe deal lands in the middle of a broader scramble to secure power for digital infrastructure. In 2024, data centers worldwide consumed an estimated 460 terawatt-hours of electricity per year, roughly on par with the entire UK’s annual use.
Forecasts from the International Energy Agency suggest that by 2027, data center consumption could double, driven by AI training clusters, cloud services and 5G-enabled applications. Traditional planning cycles for new transmission and large centralised plants look increasingly out of sync with that curve.
Countries are experimenting with different answers:
- In the US, developers test on-site gas microplants and consider small modular nuclear reactors next to server farms.
- In Europe, many projects lean on large solar parks, battery storage and, in the future, green hydrogen for backup.
- Chinese tech groups trial hydro-powered and hybrid wind-hydro data centers, sometimes cooled by immersion to save energy.
- Nordic countries attract data centers with abundant hydropower and naturally cold air that reduces cooling loads.
Against that backdrop, a turbine derived from a supersonic jet engine is less an oddity and more a sign of how far companies will go to secure reliable megawatts.
Fuel, emissions and future scenarios
Where the gas comes from – and what it means
Superpower is a gas turbine, so its climate footprint will depend heavily on the fuel. Burning conventional natural gas locks in carbon emissions, even if the unit operates efficiently. Using so‑called “associated gas” that would otherwise be flared, or blending in low‑carbon fuels such as biomethane or synthetic methane, would shift the calculus.
Boom has not set public fuel commitments, but the broader sector already watches the tension between AI expansion and climate targets. A data center that advertises green credentials yet runs on fossil gas will face questions, no matter how advanced its turbine core might be.
In a future scenario, such turbines could transition to hydrogen or hydrogen‑derived fuels, provided the combustion system is adapted. Gas turbines often have technical pathways for hydrogen blends, though pure hydrogen raises issues with flame speed, NOx emissions and storage infrastructure.
Key terms and practical examples
For non-specialists, a few concepts matter in this story:
- Megawatt (MW): A unit of power. One 42 MW turbine can in broad terms supply tens of thousands of homes, depending on use patterns.
- On-site generation: Producing electricity at the point of use, such as a power plant inside a data campus, reducing reliance on distant grids.
- High-temperature core: The part of a turbine where air is compressed, mixed with fuel and burned, then expanded through turbines. The hotter it runs, the more power it can extract from the same mass of air and fuel.
In a practical deployment, a hyperscale data center might pair several Superpower units with battery storage. The turbines would provide the bulk of continuous power, while batteries cover rapid ramps and brief outages. A site connected to the grid could then use the grid as a backup or export surplus electricity when AI clusters idle.
Such hybrid setups carry trade-offs. They offer speed and control but lock operators into gas infrastructure for years. Communities around new data campuses will weigh the benefits of jobs and tax revenue against emissions, noise and fuel transport. How fast technologies like Superpower catch on will depend as much on public acceptance and regulation as on engineering prowess.
