R77-239A rocket

The R77-239A Needlenose rocket is a REPCONN Aerospace rocket, representing a hybrid fossil fuel/plasma engine design. The former is used to break free of Earth's gravitational pull, the latter to bring the rocket to other planets for mining operations.

A scale model can be found on the 1st floor in REPCONN headquarters.
