E1-E9 are the superiority fighters, its our job to take out the enemy star fighters so that our bombers can use their missile's on the enemy capital ships. Making sure our bombers survive to get their Proton Missiles into the frigate is way more important than having much weaker Proton Torpedoes to fire. We also have 144 proton torpedoes, it shouldn't be possible to use even half of that against the fighters.
12 Tie Advanced vs 9 E-wings. The Ties have stronger shields, but are a bit slower than the E-wings and have less maneuverability, and less armor. We are both armed with Blaster Cannons giving us equal punch at short range. Our major advantage is that while blasters only have a range of 8 squares, or 2-4 with any kind of accuracy we also are carrying 16 Proton Torpedoes (8 in each launcher). The Torpedoes have a range of 30 squares with accuracy out to 15 squares and the ability to home in on the target.
The best bet for the Squadron is to kill as many enemy star fighters as possible before those star fighters get into blaster range when they will outnumber us, and possibly overwhelm us. A pair of fire linked torpedoes [10d10x2] can do enough damage to destroy an advanced which all told has only (120 health [90HP + 20 SR + 10DR])
