Boom's original bet was that they could use better aerodynamics and materials to get supersonic speeds using existing engines. This saves a ton of time and money since you don't need to get the engines certified. The prototype uses three non-afterburning GE J85 engines[1], which produce 2,950 lbs of thrust each. It should have a top speed of mach 2.2. The main issue is that their production aircraft will need more powerful engines, and modern civilian airliner engines have large fans, high bypass ratios, and high compression ratios, all of which make them difficult to adapt to supersonic flight. It looks like their plan is to collaborate with Rolls-Royce to build a suitable engine using an existing engine core. I hope they can pull it off. 1. https://en.wikipedia.org/wiki/General_Electric_J85 https://en.wikipedia.org/wiki/General_Electric_J85
