The term RU, a measurement of Hull rating, was a common designation when spaceships were involved. RU marked how much damage a spaceship 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, and likely has no canonicity or official correlation.

It is speculated by Curtis Saxton that RU is an abbreviation of “Resistance Units”.
