Description/Overview:
           The SU-81 series was the product of the Advanced Research and Development group at the UNSC base on Io prior to the start of the 1st Interplanetary War. This team was working on the first faster-than-light drive system that would eventually become the T-1 Intersection Drive system in 2166 AD. Initially this system was deemed a failure because all it did was generate a warp bubble that bent space-time around it, but no where near enough to “jump” through warpspace. Thus the UNSC AR&D team discarded the design as being a failure since the goal of their team was to develop a usable FTL system. Dalltan however, understood the possible application that such a generator could be used for after the plans came across his desk in 2167 AD. Immediately the then Premier of the Solar Empire had his most trusted science teams begin refining the generator into a workable cloaking device. It was not until the late 2170s that his team—who had been transplanted to Ceres in 2178—finally perfected a light bending shield generator for use on a spacecraft.
            Unfortunately for the Ceres Regency, none of their spacecraft of the late 2170s was capable of using the LBS effectively due to the fact that even with the light bending shield generator, RADAR, and EMS sensor arrays could still detect the standard warships of the Ceres Space Navy. Therefore, an entirely new vessel—equiped with stealth armor—was designed to use the light bending shield array. By 2181 this new craft, dubbed the SU-81, was put into production. This new vessel used both the light bending shield generator and RADAR/EMS absorbant armor to give it near total invisibility both in the visible spectrum of light and the electromagnetic and radio frequency ranges.
              The SU-81 Steath Unit was fitted with one Ceres Drives CD-ID-T3-50000 Type-3 Intersection Drive unit for faster-than-light travel. Three Ceres Industrial CI-EMD-T3-70K Electromagnetic drive acted as the primary sublight engine for cruising at interplanetary speeds within a solar system or planetary sphere. The most unique system of the SU-81 was its fourteen “auxilliary” Hanubeau Dynamics HD-HYIE-14K Ion engines. These drives were mounted on the craft in clusters to give the vessel the ability to dodge quickly in space.
              Ten Gever G-ITL-MarkII Ion torpedo launch tubes were mounted on the ship–six forward and four aft–and acted as the SU-81 Steath Unit’s primary weaponry. Even though three Mawzer MPC-400 PHELAC turrets were also fitted to the spacesub, these turrets were not normally usable due to the light bending shield generator of the vessel. The three PHELACs were intended for emergency use only.
              A Ceres Research LBS-700K light bending shield generator was the primary defense system of the SU-81 type steath ship. This generator made the craft totally invisible, and also impervious to both laser and PHELAC weaponry. Although it made the craft totally invisible to visual systems and LADAR (or other light based sensors/systems), electromagnetic sensors and RADAR could detect the craft. This is why the SU-81 also used steath armor that absorbed both EMS and RADAR particles, making the craft virtually undetectable and a truly “steath” craft in space. The secondary defense systems were six Europa Research ER-DF-2000A LVL-2 Gravitonic deflector field generators were added.
              The SU-81 was only a partial success during the intial phase of the Ceres conflict. This craft caused such alarm among the Jovian governments that they developed the first NADAR (Neutrino Acquisition Detection And Ranging) sensor systems to contend with this class of warship. Only 200 SU-81s were built by the Grand Duchy and all were lost during the Ceres conflict.
