Supersonic Aircraft Startup Exosonic is Shutting Down


Exosonic, a visionary startup aiming to redefine supersonic travel and unmanned aerial vehicle (UAV) technology, has recently announced its closure. After a promising five-year journey, the company's ambitious plans have been grounded by the challenges of funding and commercialization.


A Team of Aerospace Experts

Founded in 2019 by Norris Tie, a seasoned aerospace engineer with a distinguished career at industry giants like Northrop Grumman and Lockheed Martin, Exosonic assembled a talented team of experts. The company's mission was to revolutionize air travel with a focus on quiet supersonic flight and cutting-edge UAV technology.

A Trio of Ambitious Projects

Exosonic was working on three groundbreaking project

  • Horizon: A supersonic airliner designed to offer passengers a faster and more efficient travel experience, while minimizing the sonic boom impact.
  • Revenant: A large-scale UAV capable of long-range missions and high-speed flight, promising to revolutionize military and commercial applications.
  • EX-3M Trident: A subscale supersonic UAV that successfully completed its maiden flight earlier this year, demonstrating the company's technical prowess.

The Valley of Death and the Funding Challenge

Despite significant progress and a strong team, Exosonic faced the daunting challenge of navigating the "valley of death," a term used to describe the critical period between research and development (R&D) and commercialization. During this phase, funding often dwindles, making it difficult to sustain operations and bring innovative technologies to market.

The company's ambitious vision required substantial financial investment to fund research, development, and testing. While Exosonic secured over $4.5 million in venture capital funding and government grants, it ultimately proved insufficient to bridge the funding gap. The company's inability to secure additional funding from government sources or private investors forced it to make the difficult decision to cease operations.

The Future of Supersonic Travel

The closure of Exosonic is a setback for the industry, but it does not signal the end of the pursuit of supersonic flight. Other companies, such as Boom Supersonic and Aerion Supersonic, are actively working on their own supersonic aircraft projects. However, the challenges faced by Exosonic serve as a stark reminder of the significant technical and economic hurdles that must be overcome to bring supersonic travel to the mainstream.

As the aerospace industry continues to evolve, it is essential to learn from the experiences of companies like Exosonic and to invest in research and development to push the boundaries of what is possible. By addressing the challenges of funding, regulation, and public acceptance, the dream of affordable and sustainable supersonic travel may one day become a reality.
