ComSat Lx is a rocket with a small payload satellite and is able to get to LKO with an incredible TWR and a very small launcher vehicle. Comsat Lx is a very small rocket with only two 1.25 fuel tanks and a small LV-45 “Swivel” liquid fuel engine to get it partially to orbit with the very small LV-1 “Ant” liquid fuel engine lifting a Probodobodyne OKTO probe core into orbit.

The ComSat Lx has over 5300 m/s of delta-V, enough to orbit the Mun or Minmus or fly by almost any body in the solar system. However, the ComSat is not very useful without adding some scientific equipment.
