The name of the "new concord jet"?

Question

What is the name of the jet that is better than the concord? I think it looks similar.

Answer 1

Boeing Sonic Cruiser or the 20XX. But boeing canceled the development in 2002, to focus on the Dreamliner, for a slightly slower speed,but better fuel encomony.

Answer 2

There are a few different planes, I don't know specifically which one you are talking about - the Russians generally ripped off the Concorde and made a faster, but less fuel efficient plane called the Tu-144 Charger.

Boeing conceptualized a high, but not supersonic speed, plane called the Sonic Cruiser, which was cancelled in pursuit of the 787 Dreamliner.

Boeing also conceptualized an SST, with one version using swing wings called Boeing 2707.

Japan's version of NASA, JAXA, made a concept similar to the later concepts of the 2707 so far just called the JAXA SST.
