CUVX Design – VT Team 2 Page 100Appendix C – Operational Requirements DocumentOperational Requirements Document (ORD1)Unmanned Combat Air Vehicle Carrier (CUVX)HI3 Alternative1. Mission Need Summary.CUVX is required to support unmanned combat air vehicles (UCAVs), unmanned air vehicles (UAVs) andLAMPS helicopters to perform the 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 theVirginia Tech CUVX are provided in Appendices A and B. CUVX 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. CUVX 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.CUVX 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, CUVX will continue to monitor all threats. It will likely be the first to arrive and last toleave the 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 (CUVX). These alternatives are: 1) a modified-repeat LPD-17 design; and 2) an entirely new CUVX 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. CUVX 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 CUVX alternatives within the scope of the ADM was identified based on lead and follow shipacquisition cost, effectiveness and risk. Only low to middle alternatives satisfied the follow-ship acquisition costrequirement, and only LPD-17 modified-repeat alternatives satisfied both the follow-ship and lead-ship acquisitioncost requirements. This ORD specifies the requirement for Concept Development of CUVX alternative HI3, aWave-Piercing Tumblehome Monohull design. Other alternatives are specified in separate ORDs. Based on thefollow-ship acquisition cost ND frontier (Figure 1), HI3 is the non-dominated design at the highest cost, risk, andeffectiveness end of the 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 the 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 the customer’s threshold, but is an
