CUVX Design – VT Team 2 Page 453.7 HI3 Baseline Concept DesignThe HI3 design is the highest risk, follow-ship acquisition cost and effectiveness non-dominated designidentified by the MOGO. The high OMOR of 0.288 is due to the Advanced Double Hull, Wave PiercingTumblehome, Launch Deck, Full Ship Collective Protection System, Electromagnetic Launching System, andIntegrated Power System. These are all higher risk alternatives. Table 28 - Table 33 summarize the baseline shipcharacteristics. Table 28 shows the design variables and ranges considered for CUVX and the design variablevalues selected for HI3. The endurance range tankage volume was limited due to the reduced volume in the WPTHhull form. Flight deck area was also reduced due to the tumblehome. The propulsion system uses 5 propulsiondiesels (see Table 13 propulsion system details), and was necessary to achieve the threshold range. Table 29 liststhe ship weights and vertical centers of gravity by SWBS groups with margins. Table 30 summarizes arrangeablearea. Table 31 is an electric power summary by SWBS group. Table 32 lists principal characteristics withdescriptions of the propulsion system and combat systems. The dimensions were altered slightly from the shipsynthesis model to accommodate an even frame spacing of 3 m. This table also contains information about numberof elevators, manning broken down by ship/air officers and enlisted, deck heights, and lead/follow ship costs. Table33 summarizes the values given to each Measure of Performance in determining HI3’s Overall Measure ofEffectiveness and Risk. All values are at the goal or close to it except for the threshold endurance range and damagestability because of the wave piercing tumblehome.Table 28.
