Y-wing is a bomber, it shouldn't be in the intercept list. Only A-wing, X-wing, and headhunter should. Maybe it's set as assault? I need to make sure the B-wing does not try to intercept either. Now that you mention it I'm not sure I've ever seen a Y-wing drop bombs, the tie bombers do without problem though. They both have basically the same weapons. Except the Y-wing has an ion cannon turret in addition to bombs, protons, and lasers, the tie bomber has concussion and bombs and lasers.
