This big stick of a rocket was originally intended for sending things to far-off continents very, very quickly, but now sends things into orbit instead with its four solid-fuelled stages plus a final monopropellant propulsion system (a highly cut-down version of the Cannabis upper stage). All the stages are equipped with retrofiring sepratrons to make sure they reenter Kerbin’s atmosphere, including the payload bus. It currently carries a payload of eight comms-relay Cubesats, mounted in one tall stack atop the payload bus.

My KSP version of the Minotaur I orbital launch vehicle (a Minuteman II ICBM repurposed as a satellite launch vehicle), the Baculum Magnum (meaning Big Stick in undoubtedly-incorrect Latin) here carries a demonstration payload consisting of four Relay CubePaks, for a total of eight Cubesat relays that it can place into a comfortably-high orbit.

Since the Pollux SRB used for the first stage lacks gimballing capability, a set of twelve RCS thrusters on the sides of the stage’s tail is provided for pitch and yaw control, while roll control (plus additional pitch and yaw control) is provided by the first stage’s moveable aerodynamic tailfins.

A stock rocket called Baculum Magnum. Built with 185 of the finest parts, its root part is probeStackSmall.

Built in the VAB in KSP version 1.10.1.
