Unlike the train there is no timer. Be sure to save.
The easiest way to do this is to play on Easy.
On Easy the enemies are almost literally no threat. Use Dash to avoid enemy cannons and get to each ship as fast as you can. You can use homing lasers to take out ship's defenses but that's hardly necessary. I did this without attacking a single enemy OF.
Get behind each ship and land on the back part right behind it's weak point, then use your Vektor Cannon. There may be a Raptor slashing at you but in my experience he will not do much damage nor knock you out of your cannon-firing-stance.
In short, rush in recklessly and destroy the enemy ships as fast as you can, running away from rather than wasting time fighting their intercepting units.
I know for a fact his solution works on EASY, and acknowledge it will most likely get you killed on any other difficulty.
On a higher difficulty just take out the enemy OFs as fast as you can . I'm fairly sure you can still just dodge and ignore the enemy AA weapons.
