XIA Tier 2 spacecraft with 3mm mount hole NOW REGULATION XIA SPEC!! The Slipstream II-A is a direct rebuild of the prototype I-A keeping true to its versatile well-rounded design utilizing the same rear-mount external cargo bay which allows slightly more cargo space at the cost of balance and stability in atmospheric flight. The II-A is upgraded to 6 forward facing weapons/sensor mounts, a roomy cargo bay, and reliable XR2 engines to compensate for the added mass of a T2 ship. Slipstream Systems Bonus: Slight Environmental Damage Mitigation. Optimized for WSFP.
