Like the preceding Delta-class DX-9 transport, the ATR-6 had two general purpose warhead launchers, and a pair of forward-firing ion cannons. Both were designed to ferry troops into the combat zone to capture enemy craft. The ATR-6 also featured stronger shields and a more heavily reinforced hull than the DX-9. While the DX-9 could be destroyed with a pair of proton torpedoes, it was reported that an ATR-6 could survive three hits from such warheads.
