Boom Supersonic is designing the Overture, a 64-80 seat Mach 1.7 commercial airliner, alongside its own Symphony turbofan engine. The XB-1 demonstrator achieved its first supersonic flight in January 2025, and the Trump administration's June 2025 executive order lifting the 50-year overland supersonic ban materially expanded Boom's addressable market. American Airlines, United Airlines, and Japan Airlines have placed pre-orders for Overture.
