These can be replaced with bombs: 4000kg payload.
Each wing has three hardpoints. Each hardpoint can carry either one Angel of Death 2, one Firebird, one CBM-200 Missile or multiple Diamondbacks on a rack. Diamondbacks are 8 if on the inner hardpoint, 7 on the middle, or 6 on the outer, the middle hardpoint precludes mounting diamondbacks on the outer or inner hardpoints. Note that all missiles must be expended or jetisoned to transform or enter atmosphere. Typical load is one Firebird and 14 diamondbacks per wing(2 and 28 total).
