The AS3 conceptualization and design work is currently under way, with more details set to be revealed later in 2021. It does not even exist on paper today.
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.
A business jet is a far cry away from a commercial airline jet.
