Belt Alliance Delta Tri Light Fighter Class History The Delta Tri Ligth Fighter was designed to give Belt Alliance pilots a better chance of damaging a ship when engaging it than a normal Delta V. The first two Delta Tri models could, in addition to their onboard weapons, carry missiles on external hardpoints. The FS-3M Delta Tri was armed with standard Delta V weapons. The FS-3P was armed with two lighter versions of the Starfox medium fighter's guns. The FS-3S was armed with two of the lighter Delta V's weapons, as well as one underslung Starfox Matter Gun. It could not carry any weapons on external hardpoints. Delta Tri SF-3M Delta Tri SF-3P Delta Tri SF-3S
