Originally he wanted to have two fighters with bombs, and each of them would have a sinlge escort, but once Vagabonds fighter was destroyed, he had a choice of either two Excals protecting him, or a single Excal protecting him and either Maniac or Flint.
Did I mention that to carry the T-bomb you have to drop all your missiles and your ship will be slughish as hell? So then you have a single fighter, and two ships incapable of protecting themselves.
