I am new to this system & we ( my gaming buddy & I, not my other self) are having a disagreement on stealth. It is my opinion that ships cannot be stealthy at QM Tech level 3 but that can happen only at Tech level 4. He feels that there are 2 stealth generators, a standard & an advanced. At Tech level 3 you get the standard that allows ships to be stealthy & at Tech level 4 you get the advanced that also allows them to be stealthy (but on again & off again.)
Also I cannot find the stats for heavy strike fighters. Do they exist?
