Does anyone know what the "ship quality bonus" does?

from GalCiv2 Forums
There is a bonus given with the STellar Forge and sometimes with a planetary event upon colonization that bestows a "ship quality bonus" for any ship built on that planet.  Does anyone know off-hand what bonus this actually gives the player?

It improves both attack and defense on ships built there.

MAYBE it improve Def. and Att., I don't know exactly. But, I'll test it later because I saw Def. and Att. increace when creat a fleet, creat a fleet will make it more clearly.

It is surely increase 25% hitpoint for your ships built with a StellarForge.

The Forge in particular actually does both (it provides a 25% starship bonus and a 25% HP bonus). The 'pirates in orbit' colonization event only gives a starship bonus.
