Making the most of a supersonic business jet means more than just going fast.


While flying Mach 1.6 is an achievement in itself, flying efficiently is even more impressive.

Efficiency equals flexibility — because the AS2 can achieve the same fuel efficiency in the subsonic regime as when supersonic. This is quite innovative in comparison with the iconic Concorde which burned much more fuel at subsonic speeds.

The AS2 is also designed to operate from airports commonly used by business jets today, such as Midway, Van Nuys, Teterboro, Farnborough and Le Bourget. Moreover, the AS2 will require no specialized ground equipment.

In short, you can use it as you use today's long-range jets. You’ll just spend less time aboard. (Unless you choose to fly more frequently - a distinct possibility, as you can visit more places and get more accomplished than is possible using subsonic transportation.)

In all likelihood, you’ll combine high-subsonic, low-supersonic and high-speed supersonic cruise in one flight, as in our Chicago to Frankfurt example below.


Over the U.S., federal law prohibits supersonic flight. Outside U.S. borders, and while above populated areas, the AS2 can operate at speeds between Mach 1.1 and 1.2 without creating a sonic boom on the ground (a phenomenon known as Mach cutoff and described in our Technology section). Over water, pilots can open the throttle and fly as fast as Mach 1.6. So it’s possible to fly route segments at three different cruise speeds in one trip.

Landing distance will be less than 4,000 feet. For takeoff, required runway length is 7,500 feet when fully fueled. However, with a reduced fuel load, the aircraft will retain trans-Atlantic range and be able to operate from runways of 6,000 feet or less.

The AS2 flies from Chicago to Frankfurt in 5 hours, 8 minutes at a combination of high subsonic and supersonic speeds.


Unlike previous generations of supersonic wings, the AS2 wing is as efficient at high subsonic cruise as it is supersonically. The AS2 will cruise as efficiently at Mach 0.95 as it will at Mach 1.4. For this reason, Aerion engineers refer to the design as having two "sweet spots" of operation.

Operating "sweet spots" at both Mach 0.95 and Mach 1.4.
