By comparison to the Concorde this new design is intended to carry three times as many passengers and fly roughly at the same speed (Mach 2) 1,522.4 mph (2,450.1 km/h).
The goal is to achieve a ticket price comparable to that of subsonic business class.
[1] One of the most crucial factors in the commercial viability of a supersonic transport is the strength of the sonic boom it generates.
Since the 1960's a number of techniques have been developed that may reduce the effect (see the sonic boom article).
On May 9, 2008, JAXA announced it would collaborate with NASA to conduct joint research on sonic boom modeling.
