TIER 3 Ship in REGULATION XIA SPEC!! 3mm mount hole. The Slipstream BR-2 came to be after numerous captains' requests for a larger, more heavily armored ship. Yes, apparently the BR-1 just wasn't BIG enough!?! Subsequently, the BR-2 Super Heavy was born. The E designation retains the extended flight control surface ring to compensate for its overbearing mass when in atmosphere and to concentrate warp output in vacuum.The Engines were overhauled from the extended IV Series ensuring adequate thrust even with a full payload and it has retained the Slipstream's overall encompassed hull design making it an extremely durable, solid ship. This military variant of the civilian model is equipped with double the standard defensive beam arrays covered over node-like blisters at key locations on the ship as well as reinforced playing over the heat exchangers and has recently been quite popular once again in the civilian market on the outer rims. SLIPSTREAM SHIP SYSTEMS: slight mitigation of any environmental damage. This model has been hollowed and is Optimized for WSFP.
