Ship Design mechanics questions

[Mardoc]

I'm looking at designing ships for OSG-29. Without any details, I've run into a couple things that confuse me:

Do missiles benefit from Battle Computers on the ships that launch them? I read descriptions that say things like 'guided by a +1 level computer' and I'm not sure what the +1 is comparing to.

What does ship maneuver speed actually do? Does it just allow tactical movement speed?

The to-hit bonus for missiles stacks with the ship computer's bonus, so if you have a level-1 computer and a missile with +1 to hit, you get a total of +2. Maneuver increases both speed on the tactical map and defense.

Thanks, guys!
