I'd like to spend a question to ask: Of a primary objective, secondary objective, or bonus objective, which of them is the ship's survival as a goal?
Technically I should probably reject this and require it be asked as "Is the ship's survival a primary objective?"
I will answer it as precisely as I can:
The ship is not listed in any of the mission's objectives.
However, because mission objectives do not determine whether or not you can proceed in the campaign, see
[losing the ship] is a partial and/or total fail condition.
