(CNN) — Right now, a lot of us can’t even fly out of our own countries, but if Florida-based planemakers Aerion are to be believed, by the end of the decade we’ll be able to jet between Los Angeles and Tokyo in under three hours.

The Aerion AS3 is a Mach 4+ commercial airliner, revealed Monday, that its manufacturers say will be able to carry 50 passengers at a range of 7,000 nautical miles.

“Our vision is to build a future where humanity can travel between any two points on our planet within three hours. Supersonic flight is the starting point, but it is just that — the beginning,” said Aerion’s chairman, president and CEO, Tom Vice, in a statement. “We must push the boundaries of what is possible.”

Earlier this year Aerion expanded its ongoing partnership with NASA’s Langley Research Center, with a specific focus on commercial flight in the Mach 3-5 range.

To put that in layperson’s terms, that’s 2,300 to 3,800 miles per hour, or 3,700 to 6,200 kph — or up to seven times as fast as a regular long-distance passenger plane.

Conceptualization and design work is currently under way, with more details set to be revealed later in 2021.

The AS3 is the second plane to be revealed in Aerion’s family of jets, and there are also future plans for hybrid-electric supersonic planes.

The AS2 — which promises to fly New York to London in 4.5 hours — is Aerion’s bid to become the first supersonic passenger aircraft to enter commercial service in more than 50 years.

The 8-12 passenger business jet will travel at Mach 1.4 (more than 1,000 mph), with production starting on the supersonic craft in 2023. The AS2’s first flight is slated for 2024 and the company intends to take the plane to market in 2026.

New supersonic era

The last supersonic passenger jet to traverse our skies was, of course, Concorde, which retired from service more than 17 years ago. While an engineering marvel, it was high on costs and high on environmental impact.

“Concorde was a brilliant piece of machinery, a noble experiment, but it put too much emissions in the environment, too much noise into our communities, and was too expensive to operate.

“What we’re trying to do is very different,” Vice told CNN Travel in 2020.

Aerion’s ambitions are for its aircraft to operate benignly in the skies: “The world can’t wait until 2050 to become carbon neutral. We have to do this today,” Vice said.

‘Lowest fuel-burn possible’

Partners in Aerion’s AS2 program include GE, which is producing the Affinity supersonic engine, and Spirit AeroSystems, which is making the AS2’s pressurized fuselage.

In the cockpit, Honeywell is revolutionizing the flight deck, using its expertise in supersonic military jets to design the AS2’s mission processors, displays, sensors and flight control systems.

“We had to design an aircraft that was incredibly efficient with the lowest fuel-burn possible, so we spent 10 years thinking about advanced aerodynamics and fuel-efficient engines. We’ve designed specifically around noise and emissions,” says Vice.

One of the things it won’t have — which Concorde had — is afterburners, a system whereby fuel is sprayed into the engine’s exhaust and burned to increase thrust during takeoff and acceleration.

“We ruled that out because it’s too noisy and puts too much emissions in the environment,” says Vice. “The second thing we thought about was our energy source. We wanted an aircraft that wasn’t dependent upon fossil fuels and that could operate on 100% synthetic fuels from day one.”

The company is also committed to a substantial reforestation program to assure carbon offsets for every customer on every flight.

‘Boomless cruise’

Then there’s noise. Vice told CNN in 2020 that the AS2 is designed to meet Stage 5 Airplane Noise Standards, the most stringent landing and takeoff noise regulations. “We think we’ve solved that problem,” says Vice. “Our aircraft is going to be as quiet as other airplanes around airports.”

But perhaps one of the AS2’s most innovative features is its “boomless cruise” which allows the plane to fly supersonically over land without the boom striking the ground. Instead, the noise gets refracted back up into the atmosphere.

Aerion invented “boomless cruise” because the alternative type of quieter supersonic flight, called “low boom,” while less noisy than Concorde, still produces noise on the ground similar to the rumble of distant thunder.

Vice is keen to prove the new technology can work and “once regulators see that we can do that reliably, we’ll have the first aircraft in history that can fly supersonic over land, and nobody on the ground will hear the boom.”

Vice reckons that “boomless cruise,” coupled with carbon-neutral operations, will deliver compelling productivity advantages for prospective AS2 customers.

“We analyzed how business owners fly. We looked at a company out of New York that flew business jets around the world, and when we substitute an AS2 for them and rerun those flights for every person who flew on their airplane, AS2 saved them 142 hours a year,” said Vice.

Aerion has several competitors in the supersonic and hypersonic aviation fields, but the one currently creating the most buzz is Boom.

In October 2020, the Denver-based start-up made history by rolling out its XB1 demonstrator aircraft, the first independently developed supersonic plane.

Dubbed Baby Boom, the 71-foot-long fuselage is a 1:3 scale prototype of Boom’s upcoming supersonic commercial jet Overture, which is to have a maximum speed of Mach 2.2, making it capable of flying London to New York in just three hours and 30 minutes.
