Wizkids Rules!

"When a friendly ship within range 1 of your ship is attacking an enemy ship in your forward firing arc, if you haven't already attacked this round, you may discard this card to add a number of attack dice to that ship's attack roll equal to the number of attack squadron tokens on your ship card. you cannot attack during the round you use this ability. no ship may be equipped with more than one "flanking attack" upgrade."

Can this card be used when the ship being attacked is at range 3 of the fighters (who can normally only attack at range 2)?

If the Fighters have equipped Galor Class Phaser Banks ("Your ship's primary weapon can target ships at Range 1-3..."), Can this card be used when the ship being attacked is at range 3 of the fighters?

No your fighters may not participate in any attack using flanking attack at range 3. Their range is restricted to Range 2.
No, just like Barrage of Fire you are adding dice with Flanking Attack. The Galor Class Phaser Banks will only allow you to directly attack at range 1 through 3.
