The D-SEND #2 project features a 3D lifting body, the S-cube Concept Model (S3CM), with a new design that uses JAXA's proprietary low sonic boom design technology to realize low boom characteristics at its nose and tail edges. The S3CM is dropped from a ballon at an altitude of 30 km and glides over one of four boom measurement systems at Mach 1.3 and
a flight-path angle of 50 degrees. At this flight-path angle, the shaped boom signature generated by the airplane goes down vertically toward the sonic boom system.
The D-SEND#2 drop test is planned for the summer of 2013.
