<strong>CUVX</strong> <strong>Design</strong> – VT Team 2 Page 100Appendix C – Operational Requirements DocumentOperational Requirements Document (ORD1)Unmanned Combat Air Vehicle Carrier (<strong>CUVX</strong>)HI3 Alternative1. Mission Need Summary.<strong>CUVX</strong> is required to support unmanned combat air vehicles (UCAVs), unmanned air vehicles (UAVs) andLAMPS helicopters to perform <strong>the</strong> following missions:1. Intelligence, Surveillance, and Reconnaissance (ISR)2. Suppression of Enemy Air Defenses (SEAD)3. Anti Submarine Warfare (ASW) self defense4. Anti Surface Ship Warfare (ASuW) self defense5. Electronic Countermeasures (ECM)6. Mine Warfare (MIW)7. Time-sensitive Air and Missile StrikesThe Mission Need Statement (MNS) and Acquisition Decision Memorandum (ADM) developed for <strong>the</strong><strong>Virginia</strong> <strong>Tech</strong> <strong>CUVX</strong> are provided in Appendices A and B. <strong>CUVX</strong> will operate primarily in littoral areas,depending on stealth, high endurance, minimum external support, low cost and low manning. It will support 10-30UCAV’s and 5-20 UAV’s, providing for takeoff and landing, fueling, maintenance, weapons load-out, planning andcontrol. <strong>CUVX</strong> will operate independently or in conjunction with small Surface Attack Groups (SAGs). It will becapable of performing unobtrusive peacetime presence missions in an area of hostility, and immediately respond toescalating crisis and regional conflict.<strong>CUVX</strong> is likely to be forward deployed in peacetime, conducting extended cruises to sensitive littoral regions.It will provide its own defense with significant dependence on passive survivability and stealth. As a conflictproceeds to conclusion, <strong>CUVX</strong> will continue to monitor all threats. It will likely be <strong>the</strong> first to arrive and last toleave <strong>the</strong> area of conflict.The UAV’s will provide surface, subsurface, shore, and deep inland surveillance, reconnaissance and electronicwarfare. The UCAV’s and LAMPS will provide initial/early conflict ASW, ASuW, SEAD, and MIW.2. Acquisition Decision Memorandum (ADM)The ADM authorizes Concept Exploration of two material alternatives for an Unmanned Combat Air VehicleCarrier (<strong>CUVX</strong>). These alternatives are: 1) a modified-repeat LPD-17 design; and 2) an entirely new <strong>CUVX</strong> design.The concepts considered in Concept Exploration are required to include moderate to high-risk alternatives. Averagefollow-ship acquisition cost shall not exceed $650M ($FY2005) and lead ship acquisition cost shall not exceed$750M, not including aircraft. <strong>CUVX</strong> concepts will be explored in parallel with UCAV-N Concept Exploration anddevelopment using a Total Ship Systems Engineering approach.3. Results of Concept ExplorationConcept exploration was performed using a multi-objective genetic optimization (MOGO). A broad range ofnon-dominated <strong>CUVX</strong> alternatives within <strong>the</strong> scope of <strong>the</strong> ADM was identified based on lead and follow shipacquisition cost, effectiveness and risk. Only low to middle alternatives satisfied <strong>the</strong> follow-ship acquisition costrequirement, and only LPD-17 modified-repeat alternatives satisfied both <strong>the</strong> follow-ship and lead-ship acquisitioncost requirements. This ORD specifies <strong>the</strong> requirement for Concept Development of <strong>CUVX</strong> alternative HI3, aWave-Piercing Tumble<strong>home</strong> Monohull design. O<strong>the</strong>r alternatives are specified in separate ORDs. Based on <strong>the</strong>follow-ship acquisition cost ND frontier (Figure 1), HI3 is <strong>the</strong> non-dominated design at <strong>the</strong> highest cost, risk, andeffectiveness end of <strong>the</strong> design space. It has a lead ship acquisition cost of $1.19B and a follow-ship acquisition costof $772M with excellent effectiveness (OMOE=.9021) for <strong>the</strong> risk (OMOR=0.2877). It carries 28 UCAVs, hasstealth characteristics, excellent aircraft weapons and fuel capacity, an Integrated Power System (IPS), and isprotected by an Advanced Double Hull (ADH). Its cost and risk are above <strong>the</strong> customer’s threshold, but is an
<strong>CUVX</strong> <strong>Design</strong> – VT Team 2 Page 101excellent alternative for a challenging and innovative student project and will provide important insights into <strong>the</strong>application and benefits of potential transformational technologies.Figure 1. <strong>CUVX</strong> Non-Dominated (ND) Frontier4. <strong>Tech</strong>nical Performance Measures (TPMs)5.
