Advancing Toward Production
Since first being announced in December 2022, Symphony has completed key design milestones and moved into hardware testing.
Rig Testing Underway
Symphony is now advancing through more than 30 rig tests, allowing for validation and optimization of all key engine components, ranging from fan and nozzle acoustics to combustor fuel efficiency.
Operational Engine Core in 2025
Boom has accelerated development of a full-scale engine core, which will be operational in late 2025. Engine core testing will analyze performance of the compressor, combustor, and turbine section.
Symphony Assembly Facility Secured
Boom selected StandardAero to perform Symphony engine assembly at its San Antonio, Texas location. The Symphony production line will scale to produce 330 engines annually within a footprint projected to total over 100,000 square feet of production space.
Partnering with World-class Suppliers
Florida Turbine Technologies (FTT)
FTT is leading Symphony engine design and assembly of initial development units.
Supersonic Experience
The FTT engineers working on Symphony include members of the team responsible for the design of the F-119 and F-135 supersonic engines powering the F-22 and F-35.
“We believe there is large market potential for both Overture and Symphony, which will be transformational for the future of supersonic travel. The Symphony engineering team includes many of the best and most experienced engine designers on the planet, and we’re thrilled to expand our role to include the initial assembly of engines for ground test, flight test, and certification.”
