As we enter 2023, private aviation finds itself at the forefront of advancement for the entire industry. Having always been the testbed for technological innovation, today private jet manufacturers are leading the line in pursuit of the fastest, the biggest, and the most fuel efficient aeroplanes.
More than a half-century after a Bell X-1 rocket plane shuddered and shook its way through a newly discovered pressure wave with Captain Charles “Chuck” Yeager at the controls on October 14, 1947, it is the private aviation market pushing speed boundaries.
Little did the pilot and observers know that the sonic boom that shattered the desert calm that morning also became the harbinger of doom for supersonic flight — at least over the continental US. First, Congress passed the Aircraft Noise Abatement Act of 1968. Acting under this authority, the FAA proposed a regulation to restrict the operation of civil aircraft at speeds greater than Mach 1, unless authorized by the FAA.

The regulation was finalized on March 28, 1973, but within aviation circles this was viewed as just a setback rather than a sunset for supersonic flight. Over the ensuing years, business aviation manufacturers continued to satisfy their clientele’s hunger for speed by offering aircraft capable of cruising within a cat’s whisker of Mach 1.

Here, we examine 10 of the fastest private jets, ideal for traveling in comfort and luxury while cruising miles above the Earth at nearly supersonic speed. These aircraft offer the fastest travel currently available. We also provide some hints about what’s next in the perpetual quest for supersonic flight. Waiting in the wings, if you will, are several developmental aircraft racing for the hangar door to demonstrate supersonic flight.
Unlike their predecessors, the modern-day aircraft designers of these machines intend to achieve their goals with little to none of the picture-frame-shattering sonic booms that brought an end to supersonic flight over the US. Welcome to the next step in the future of business aviation and the SSBJs — supersonic business jets — preparing to fly us beyond Mach 1.
Please note, Mach is a speed measurement based on the speed of sound. Since sound travels at different speeds in different conditions, the calculations here are based on Mach 1 = 741.09699 m

Fast forward back to supersonic: The future holds promise with revised restrictions
Consideration of the impact of sonic booms from supersonic flight preceded the development of the Concorde aircraft and the eventual ban on flying at Mach 1.0 or faster over the US. Those rules went into effect in the early 1970s. Jump ahead almost 50 years to today, and you’ll find the FAA already working on updated rules to help foster and accommodate the development, testing and operation of supersonic aircraft, all with an eye toward making the fastest private jets supersonic. The FAA’s rules and Congressional intent aside, the aerospace industry never stopped at the edge of supersonic. Now the Sun appears ready for a supersonic sunrise on the civil side of aviation, as new-generation dreamers and schemers pursue aircraft capable of achieving supersonic flight. But today’s developmental efforts include aircraft designed to fly without the accompanying sonic shock. Meet the leaders of this small pack pursuing supersonic flight for business and commercial aviation.
Boom Supersonic XB-1 Overture SST Demonstrator
Boom Supersonic reached a significant milestone in the firm’s development of the 55-seat Overture supersonic airliner with a virtual rollout on October 7, 2020 of the XB-1 demonstrator. It’s an important step in the company’s plans for the carbon-composite airliner. Powered by a trio of GE J85-15 engines, Boom will use the XB-1 as a one-third scale demonstrator to pave the way for its Mach 2.2, 55-passenger Overture SST. The announced rollout date came as the XB-1 demonstrator neared completion ahead of the start of ground tests later in 2020 followed by flight trials in 2021. Boom holds 30 pre-orders for the Overture from Japan Airlines (JAL) and Virgin Group. Boom expects Overture flights to focus on 500+ primarily transoceanic routes that benefit from supersonic speeds — city pairs such as New York/London and San Francisco/Tokyo. The aircraft’s design mitigates the sonic boom issue by cruising efficiently at subsonic speeds over land.
Spike Aerospace Spike S-512
The Spike S-512 SSBJ is a sleek aircraft designed to cruise at Mach 1.6, a nearly 40% time savings over long flights. With seating for up to 18, the elegant S-512 has a 7,100-mile range and features Quiet Supersonic Flight technology, without the sonic boom effect. Instead of windows, the Boston-based company plans to deliver rich, full-color panoramic displays of the outside world in the main cabin; this technology will also be used to watch movies or presentations — right on the cabin wall. Spike’s S-512 is the only supersonic jet in active development that expects to fly at Mach 1.6 without the disruptive sonic boom effect that is prohibited globally, thanks to a low 75 Pldb sound level on the ground — like soft thunder.
