In Pictures: Boom Supersonic Unveils Overture Superfactory in North Carolina

Apparently their XB-1 starts supersonic flights tests this year [1].

Given their prototype just flew, isn’t staging for mass production premature? Is Overture even in prototype? (EDIT: Right, they haven’t built the engine yet [2]. Confused why this “superfactory” is a priority.)
