No. It only targets missiles with homing capabilities. GPB, being a bomb, is not targeted. That is an advantage about it. On the other side, you can notice it's harder to use GPB because of its short lock-on range and because, being a bomb, you cannot launch it when flying inverted. Considering that, it can be really dangerous trying to launch the GPB while being pursued by a defensive fighter.
The bomb may miss the target just like a missile, depending on the situation. That happens to me sometimes when I make a bad bombing approach in that I go way too fast and from a poor attack angle because of someone pursuing me, giving me very little room to bomb the ships. EDIT: I forgot to mention that when this happens, the "MISS" message won't appear despite the fact that it's a homing weapon.
Hi there! If you want to play with me, make a request here. My PSN account is "felcas01", and I play on Friday, Saturday, Sunday and, occasionally, on Tuesday and Wednesday. I normally play only with supplied fuel, but there're some exceptions. I play at 9:00am-11:00am and 9:00pm-11:00pm (that is Brasilia time: GMT-3 hours). However, if you want to play at another time, make the request anyway, and I'll check the possibility. See you in the skies!
