RU was a measure of a starship's hull rating. It indicated how much damage the ship could withstand before breaking up.

Behind the scenesEdit

The RU hull rating system was created for the X-wing computer game series as a game mechanic. Curtis Saxton speculated that RU stands for "Resistance Units."
