One thing has always been true about rockets: The farther and faster you want to go, the bigger you rocket needs to be. Why? Rockets combine a liquid fuel with liquid oxygen to create thrust. Take away the need for liquid oxygen and your spacecraft can be smaller or carry more pay load.That's the idea behind a different propulsion system called "scramjet," or Supersonic Combustion Ramjet The oxygen needed by the engine to combust is ...supersonic combustion ramjets (scramjets), and mixed-cycle ramjet/scramjet/rocket engines intended primarily for missile applications for flight speeds from Mach 2 to Mach 8.
