== Supersonic aircraft development ==
Besides the H-IIA/B and [[Epsilon rocket|Epsilon]] rockets, JAXA is also developing technology for a next-generation [[supersonic transport]] that could become the commercial replacement for the [[Concorde]]. The design goal of the project (working name [[Next Generation Supersonic Transport]]) is to develop a jet that can carry 300 passengers at [[Mach number|Mach]] 2. A subscale model of the jet underwent aerodynamic testing in September and October 2005 in Australia.<ref>{{cite news|url=https://www.smh.com.au/national/supersonic-jet-test-hailed-a-success-20051010-gdm839.html|title=Supersonic jet test hailed a success|publisher=Sydney Morning Herald|date=10 October 2005|access-date=28 April 2023}}</ref>

In 2015, JAXA performed tests aimed at reducing the effects of supersonic flight under the D-SEND program.<ref>{{Cite web|url=https://www.aero.jaxa.jp/spsite/d-send2/|title=D-SEND#2試験サイト &#124; JAXA航空技術部門|website=www.aero.jaxa.jp|accessdate=20 December 2022}}</ref> The economic success of such a project is still unclear, and as a consequence the project has been met with limited interest from Japanese aerospace companies like Mitsubishi Heavy Industries so far.{{fact|date=January 2024}}
