The Delta II 2nd Stage functions as both a tug and as a rocket stage, and can be seen as a more powerful variant of the Tug Module.

It is similar in shape to the Delta 2nd Stage, but adds thrusters for manoverability while in orbit. Due to a lack of fuel and thruster propellent, this stage is best used as one of the final stages on a rocket, as its ability to rotate before detaching its payload helps you orient objects like the Communications Satellite in Mission 1.
