The missiles ignore shields, and so are very good for taking out specific hardpoints, such as Shield Generators or Hangars.In the Rebellion campaign, you must steal this technology from the Imperials at Tech Level 2.This unit is generally superseded by either the Corellian Gunship or the Marauder-class Corvette. It takes several shots to affect even a Tartan this way. You need a lot of them to disable a large ship in the first volley - very useful if you can manage it, but the difficulty in setting it up, and for just one target, makes this power not worth the effort. This is a fragile unit in a space battle and has to be carefully protected in order to bring their Ion Cannon Blast to bear. Even if they don't, this formation tends to cause the ones moving to the edge positions to have to go around asteroid fields and nebulae and inadvertently get the attention of the enemy. You can easily have a large number of them and they can perform admirably, but if you try to move them all at once, they tend to fan out in a long row - And while maneuvering into that row, some of them often forget the Move command and end up drifting off to attack something.The AI tends to send them one at a time, however. A large gang of them has a lot of firepower to whittle down shields of larger enemy ships, but they can be vulnerable to the concentrated fire of Tartans if you're not paying attention. Try to keep them moving as they are small and hard to hit. If you set them to target a unit, they sit still, making them easier targets.I did not use this unit at all, as the shielded Corellian Corvette provides a lot of anti-fighter firepower combined with better staying power. That said, check out this screenshot (played on Hard difficulty) where an Alliance space station, at just level 1 and with no support other than the garrison from its hangars defeats a lone Imperial Star Destroyer attacking the system, with considerable help from the Ion Cannon Blasts of the Y-Wings. A few losses are probably okay for the potential firepower of the Y-Wings, but my goal was to win without losses of units I bring into combat, either in Space or on Land. I did not use fighters at all if possible because in larger battles they are hard to manage and it is easy to lose a few wings. In the late game when you can build Mon Calamari capital ships, I took a chance and changed my fleet to five Mon Calamari Star Cruisers, two Marauders (who have to do double-duty as anti-fighter support after a battle), and one Fleet Commander. I kept the Corellian Corvette against TIE Bombers, and for the most part they survive alright. The Nebulon-Bs are changed to Assault Frigates later, and when Raymus Antilles is removed from the game, Sundered Heart is swapped for a regular Corellian Corvette. Sometimes this will work out to 23 points because the game doesn't always count Sundered Heart (heroes normally don't count toward the point total). My early fleet consisted of Sundered Heart (for anti-Fighter support), six Nebulon-B frigates, two Marauder corvettes, and one Fleet Commander. I like to run space battles with no unit losses (unless they are 'free' units that are from, for example, space station garrisons), so you won't see tips like 'keep calling for reinforcements'.
