Overview

Boom Supersonic is building Overture, a 60-80 seat Mach 1.7 supersonic airliner aimed at restoring commercial supersonic travel on 600+ routes at business-class economics. After XB-1 became the first independently developed jet to fly supersonic and completed a 13-flight test campaign in 2025, Boom shifted fully toward Overture production infrastructure, Symphony engine development, and Superpower, a 42 MW natural-gas turbine business that uses the same core engine technology. Boom now says it has nearly $1B in funding, a 130-aircraft order book from American Airlines, United Airlines, and Japan Airlines, and a $1.25B+ launch backlog for Superpower.

Main Products

Overture

Overture

In Development

Purpose-built Mach 1.7 supersonic commercial airliner designed to cut travel times in half on 600+ routes. Overture is optimized for up to 100% sustainable aviation fuel, flies at 60,000 feet, and is positioned as an all-premium aircraft for 60-80 passengers.

Boom has completed the Greensboro Superfactory, unveiled Overture's flight deck, and continues aircraft and Symphony propulsion development ahead of later integrated testing.

XB-1

XB-1

Retired

One-third scale supersonic technology demonstrator that validated the core aerodynamic, structural, and flight-control concepts behind Overture. XB-1 became the first independently developed jet to fly supersonic and completed Boom's full test campaign in early 2025.

The program concluded after 13 successful flights and six supersonic runs. Boom retired the aircraft to its Denver headquarters after the second and final supersonic flight in February 2025.

Superpower

Launched

42 MW natural-gas turbine derived from the same core engine technology as Symphony. Superpower is designed for AI data centers and other onsite power applications, emphasizing waterless operation and strong output in hot, dry environments.

Boom revealed Superpower in December 2025 with Crusoe as launch customer and says the initial order book is worth more than $1.25B.

What's Next

Run Symphony sprint core and engine tests in Colorado

Boom prepared the Colorado Air and Space Port test site in 2025 and says recent combustor work is guiding the sprint core test planned for 2026. This is the key technical gate for de-risking Symphony.

2026

Continue Overture aircraft and engine development

With the Greensboro Superfactory complete, Boom's next execution phase is continued aircraft development, more Symphony hardware work, and further manufacturing progress across the Overture program.

2026-2027

Deploy first Superpower systems for Crusoe

Boom now has a real power-generation business on paper, but it still needs to turn the $1.25B+ launch backlog into operating field deployments that prove Superpower can fund and de-risk the aviation roadmap.

Operations & Revenue

StatusDevelopment Stage

XB-1 is retired after completing its flight-test campaign. Overture remains in development with the Greensboro Superfactory complete, Symphony engine testing infrastructure being built in Colorado, and Superpower launched as a new power-generation product line.

Revenue Streams

Overture Aircraft (future)

Boom's main long-term business remains aircraft sales to airline customers. The current order book stands at 130 aircraft from United Airlines, American Airlines, and Japan Airlines, representing Boom's first five years of planned Overture production.

Superpower Gas Turbines

Superpower is Boom's new power-generation line for AI data centers. The launch order book is worth more than $1.25B, with Crusoe ordering 29 turbines that will provide 1.21 GW of capacity.

Government & Special Mission Programs

Boom is also pursuing non-airline applications of Overture through government and defense relationships, including special-mission work with Northrop Grumman and continued engagement with the U.S. Air Force.

Timeline

2025XB-1 completes supersonic campaign and demonstrates boomless cruise

XB-1 becomes the first independently developed jet to fly supersonic, then completes a second and final supersonic flight in February. The 13-flight test campaign ends with six supersonic runs and a demonstrated boomless-cruise profile before the aircraft is retired to Boom's Denver HQ.

2025Symphony engine test site selected in Colorado

Boom selects a former hypersonic test facility at the Colorado Air and Space Port for Symphony engine testing and starts investing to prepare the site for company-owned propulsion testing.

2025Launches Superpower and raises $300M

Boom unveils Superpower, a 42 MW natural-gas turbine for AI data centers, names Crusoe as launch customer with a 29-turbine order worth more than $1.25B, and closes a new $300M funding round.

2024XB-1 maiden flight and Superfactory completed

XB-1 completes its maiden flight in March 2024, and Boom completes the Overture Superfactory in Greensboro in June, giving the company its U.S. production base for the future airliner.
