A supersonic business jet (SSBJ), which many in the industry see as inevitable but just not in the near future, may have taken another step forward when Raytheon Aircraft partner Northrop Grumman unveiled its latest design for a supersonic military strike aircraft.

Northrop Grumman and Raytheon are working on what is called a “dual relevant” concept, meaning a design that could be turned into a strike aircraft or a business jet. The effort is being backed by the Defense Advanced Research Projects Agency (DARPA) and is supposed to investigate possible synergies with the private sector.
