Boom Supersonic's Overture aircraft, manufactured by the American company Boom Supersonic, is equipped with a 16-ton thrust engine and is expected to carry 65-80 passengers.

At the Paris Air Show, held from June 19-25 in Paris, the American company Boom Supersonic announced a series of agreements with new suppliers, revealing technical specifications for its Overture supersonic commercial aircraft project and Symphony engine, according to New Atlas .
New partners include the Italian company Leonardo, and the Spanish companies Aernnova and Aciturri. In addition, Boom Supersonic also released schematics of the aircraft's flight systems, avionics, landing gear, and engine specifications.
The company stated that the new fuel system can pump fuel between tanks during flight, shifting the center of gravity to suit subsonic and supersonic flight. Additionally, experts have made several modifications to allow the Overture to use sustainable aviation fuel (SAF). The Overture will feature gull-wing wings and a fuselage made of composite materials.
Aernnova is developing the gull wing to achieve better supersonic performance while maintaining subsonic handling capabilities. Like many supersonic aircraft wings, the Overture's wing is thinner than subsonic versions to reduce drag, resulting in more efficient flight. Leonardo is in charge of the engineering of the aircraft's structural components and will be a partner in the design and fabrication of the fuselage sections, including the wing boxes. Aciturri is involved in the design and development of the tail assembly, including the horizontal tail fins for better control at subsonic speeds.
The "heart" of the Overture is the Symphony engine, displayed in Paris as a 1/3 scale 3D-printed model. According to Boom Supersonic, the new engine will have a 25% longer lifespan and 10% lower operating costs than the current engine. The Symphony has nearly 16 tons of thrust, an 183 cm rotor, three low-pressure compression stages, six high-pressure compression stages, one high-pressure turbine stage, and three low-pressure turbine stages.
Overture is expected to carry 65-80 passengers and can fly at Mach 1.7 (1.7 times the speed of sound), or approximately 2,100 km/h over water. However, due to regulations and the loud sonic boom, supersonic aircraft cannot fly at such high speeds over land. Therefore, Overture will only fly at Mach 0.97, or 1,200 km/h. This aircraft model could begin operations in 2029.
