Boom Supersonic and Latecoere Sign Strategic Supplier Agreement for Overture and Symphony

Latecoere to develop the complete electrical wiring interconnect system architecture of Overture and Symphony

Today, Boom announced the selection of tier-one aerospace leader Latecoere to join its growing network of global suppliers. As part of the agreement, Latecoere’s engineering team in Toulouse, France will work with Boom engineers to define the complete electrical wiring interconnection system (EWIS) architecture for both Overture and Symphony.

“Among the major aerostructures and systems suppliers announced for Overture, Latecoere brings tremendous experience in developing and manufacturing certifiable EWIS and advanced aircraft technologies,” said Kathy Savitt, president and Chief Business Officer of Boom Supersonic. “At Boom, we continue to bring together the world’s leading suppliers on Overture and Symphony to make sustainable supersonic air travel a reality.” 

The EWIS will comprise over 103 kilometers (64 miles) of wiring, requiring more than 45,000 electrical connections, guaranteeing optimal safety and system reliability for Overture and Symphony. Latecoere has proven expertise in complex aircraft development processes and methods, and Boom will leverage the company’s industry-leading harness architecture definition software stack. 

“Latecoere is proud to support Boom with unique EWIS design engineering capabilities in the development of the world’s fastest airliner,” said Greg Huttner, CEO of Latecoere. “We are one of the founders of the aerospace industry and are determined to continue supporting the development of next generation flight with Boom.” 

About Latecoere

As a tier-one supplier to the world’s leading aviation manufacturers, Latecoere serves the aerospace industry with nearly 6,000 employees located across 14 countries. The Group operates in all segments of the aerospace industry – commercial, regional, business, defense and space – in two business areas:

  • Aerostructures: doors, fuselage, wings and empennage, struts & rods and customer services;
  • Interconnection Systems: wiring, avionic racks, onboard equipment, electronic systems and customer services.

Progress & Milestones

Boom continues to line up many of its critical aerostructures and systems suppliers. At the Paris Air Show in June 2023, Boom signed structural supplier agreements with Aernnova for Overture’s wings, Leonardo for the fuselage and wing box, and Aciturri for the empennage. The three aerospace leaders join Boom’s growing network of global suppliers. Boom also shared a comprehensive look at the systems configuration for Overture including avionics, flight controls, hydraulics, fuel systems, and landing gear—all designed and developed for optimal performance, efficiency, and safety.

Symphony, the Boom-developed engine that will power Overture, continues to advance through design, under the leadership of Scott Powell, who joined the team in August as SVP of Symphony. Boom recently conducted the Conceptual Design Review (CoDR) engineering milestone for Symphony, which paves the way toward Symphony’s first hardware rig tests planned for 2024.
