This achievement is a missable achievement unlocked in the final mission of the game.
At the end of the mission after the Star Hawk crashes into the destabilized moon you have to outrun the explosion through an asteroid field, following behind your flight leader.
Simply shift all power to engines and throttle all the way up through the asteroid field and caverns. The achievement should unlock on the mission complete screen.
Note - if you're having trouble maneuvering in the tight spaces try using a Y Wing or a ship with an enhancement with a negative impact on top speed. This should allow you to be at full throttle without going incredibly fast.
