The question is restricted to launchers that hashave already been used to launch an object ininto orbit before today (aprilApril 2018).
Some military ballistic missiles run only on solid propergol (e.g. the M51) but do not put objectobjects into orbit. The vega mainly runruns on solid propellant except for the last stage; and dodoes put objects into orbit.
Thus my question is: do any launchers running only on solid propellant and putting objects into orbit existsexist?
