Not arguing but, I read in a few places 'The XB-1 Baby Boom is a one-third-scale supersonic demonstrator, designed to maintain Mach 2.2, with over 1,000 nmi (1,900 km) of range, and powered by three 4,300 lbf (19 kN) dry General Electric J85-15s. It is expected to be flight tested in 2022' I hope they go for the RR. engine though for obvious reasons
