From New York to Paris in under four hours - quietly

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.

“Our goal is to redefine long-distance travel for business and government leaders, offering the speed of supersonic with the comfort and discretion of a private jet,” said Vik Kachoria, President & CEO of Spike Aerospace. “The S-512 Diplomat is being engineered to connect cities like New York and Paris in under four hours — quietly and sustainably.”

The company is also undertaking a complete brand refresh, including a redesigned website to better showcase its technology, market vision, and development progress.

To prepare for the next phase, Spike Aerospace is engaging with highly experienced professionals from top aerospace companies, as well as key industry partners and academic institutions, to accelerate design, certification planning, and market readiness.

The S-512 Diplomat is uniquely positioned to meet the demand for faster, more efficient travel in the global business aviation market, while addressing community concerns over noise and environmental impact.
