Atlanta, Georgia, August 14, 2025 — Spike Aerospace today announced significant progress in the development of its flagship supersonic business jet, the Spike S-512 Diplomat, designed to deliver safe, quiet, and fuel-efficient supersonic travel over both land and water.
Imagine New York to Paris in under four hours — without the disruptive sonic boom. Spike Aerospace’s S-512 Diplomat is designed to combine speed, comfort, and privacy for business leaders and discerning travelers. A new design phase is now underway, bringing quiet supersonic travel closer than ever.
Building on a strong technical foundation of research and development along with multiple design iterations, the company is now completing an enhanced study to further refine the S-512 Diplomat’s aerodynamics, cabin configuration, and low-boom performance. This work aims to validate the aircraft’s ability to meet stringent noise requirements for overland supersonic flight — a capability that would dramatically expand route flexibility and reduce travel times across the globe.
