Stealth is incredibly difficult to pull off in space. As space lacks an atmosphere (and thus particles to bleed heat into), masking your heat signature is rather difficult. Just one second of thrust from a fusion rocket or modern rocket will have you light up on every sensors within several million (if not billion) miles.

I guess I was thinking more evasion that stealth in space.

Really taking advantage of the vast size of space will help immensely in any situation be it evading alien exterminators bent on wiping your entire species out or simply trying to get the first hit on the enemy.

What's so great about the size of space is that even lasers/their big bro the particle beam become ineffective after a certain range since than the enemy would need to be able to predict your movements. However if the ship targeted keeps changing direction that is going to get tricky.
