Concorde replacement.
"...hope to debut a new supersonic airliner in 2023"
I do hope that they do get it into service, though I doubt it will happen. There have been many plans for Concorde replacements over the last 30+ years but none have got very far. That is a great pity as delta winged aircraft look beautiful, especially in flight. They are also the only planes that look like they should fly!
