Supersonic cruising speed (Supercruise). Its difference from supersonic flight without afterburner

The video lecture provides a definition and explanation of supersonic cruising speed. Graphs of the dependence of drag (0:43) and drag coefficient on the Mach number (3:13), as well as a graph of kilometer fuel consumption and examples of specific aircraft are given. Explains why a supersonic flight without afterburner is not identical to a super cruise
