+ points of solid fuel: 1)its cheaper 2)Higher readiness

– points:1)lower specific impulse ,ie less energy/mass in the sense speeding up the rocket 2)Its not adjustable in thrust magnitude nor could b stopped once ignited-------------to launch a satellite of a certain mass to a designated orbit(&height), the final and small stage must be adjustable/tunable, ie liquid fuelled.

Solid fueled military ballistic rocket adjust the range by the trajectory elevation angle (the bigger one also could be exhaust gas vectored) which is workable
