Do the mission and jump around for a while in the spots the ships spawn in:
Whilst the target is in the first location , run outside and jump onto the platform.
Jump over the gap and back whilst at the second target location.
Jump up on the platform behind the third target location.
Jump up against the glass a few times after the fourth target location part is cleared.
Jump around this bridge area which can spawn a ship nearby.
Jump up and around in multiple spots to get it to spawn on the secondary platform at the mission’s end.
