CUVX Design – VT Team 2 Page 51Hangar Deck 2 is 165.4 meters long and 25.5 meters wide; it is the largest hangar space on the ship. This deckis a holding deck for UCAVs, UAVs, and LAMPS that are waiting to be sent up to Hangar Deck 1 and prepared forlaunch. Preliminary preparations can be made on this deck if for some reason more than 5 UCAVs need to belaunched in a short period of time. In the forward end of the deck, six UCAVs may be positioned along the port sideand four on the starboard side. Two LAMPs may be stored on the port side side forward of Weapons Elevator 4.Further aft along the starboard side between Aircraft Elevators 1 and 2 there is room for five UCAVs; these fiveUCAVs are the first UCAVs to be moved up to Hangar Deck 1 as spaces become available (arrow #1, Figure 35).As these five UCAVs are moved up to Hangar Deck 1, the ten UCAVs forward are moved aft filling the newlyvacated spaces (arrow #2, Figure 35). As UCAVs are recovered they are brought down and moved into the tenforward spaces that were cleared. When UCAVS or UAVs return from a mission, ideally they will be brought downto this deck on Aircraft Elevator 1 and moved into any of the open positions (arrow #3, Figure 35). If for somereason a large number of UCAVs need to be recovered quickly, UCAVs can be brought down to Hangar Deck 1temporarily so that Aircraft Elevator 1 can be raised again to recover more UCAVs. If this occurs, the UCAVsbrought to Hangar Deck 1 can be moved down to Hangar Deck 2 on Aircraft Elevator 2 and then moved forwardinto the lineup (arrow #4, Figure 35). All 18 of the UAVs are stored on this deck for use in pre-conflict surveillancemissions. Nine of them are along the port side in the far rear corner; the other nine are along the starboard side justforward of Aircraft Elevator 1 along the side.4.1.4 Hangar Deck 3Hangar Deck 3 is 79.9 meters long and 27.6 meters wide and it is the smallest of the three hangar decks. Thisdeck is only used for aircraft maintenance and storage. There is enough room on this deck to store seven UCAVsand one LAMPS. The ship is required to have enough maintenance area to service two UCAVs simultaneously.This space is located all the way forward on Hangar Deck 3 on the port side. There is a total maintenance area of147 m 2 .4.1.5 ElevatorsThere are three aircraft elevators on CUVXHI3. Aircraft Elevator 1 is capable of carrying two UCAVs withwings and tails folded or two LAMPS, and operates from the Recovery Deck down to Hangar Deck 2. This elevatoris 18 meters long and 9 meters wide and the center of the elevator is 130 meters aft of the forward perpendicular. Itis placed as far forward as possible on the starboard side; constraining its location is the requirement to be behindthe jet blast deflector on the Launch Deck. Elevator 1 has a mechanical door on the recovery deck to cover theopening while the elevator is in the down position. This door is electric-hydraulic with a manual override. Thisallows for aircraft landing while the elevator is down and for decontamination of aircraft before entering the hangar.Aircraft Elevator 2 is capable of carrying two UCAVs with wings and tails folded and it operates from Hangar Deck1 to Hangar Deck 3. This elevator is 16 m long by 9.5 m wide and it is located at the rear edge of the ship on thestarboard side. This is the main interior elevator on the ship. Aircraft Elevator 3 can carry one UCAV with foldedwings and tail. It operates from the recovery deck down to Hangar Deck 1. It is located at the rear edge of the shipon the port side and is 9 meters long by 9.5 meters wide. UCAVs taken down to Hangar Deck 1 on this elevator canbe moved across the deck to Aircraft Elevator 2 and then down to Hangar Deck 2. This elevator is as small aspossible to limit the amount of recovery deck used. It is intended as a backup only to Aircraft Elevator 1. Elevator 3has the same mechanical door as Elevator 1.There are three weapons elevators on CUVX HI3. Two of the weapons elevators run all the way up from theweapons magazines to the Hangar Deck 1. One of these elevators (WE3) is located behind Aircraft Elevator 1 onthe starboard side 160 meters aft of the forward perpendicular. The other (WE4) is further aft on the port side 177meters from the forward perpendicular. Placing it here leaves enough room between it and Aircraft Elevator 2 topark one LAMPS out of the way. Weapons Elevator 2, WE2, only runs up to Deck 6. This elevator is located 124m from the forward perpendicular along the starboard side. Weapons Elevator 1, WE1, is located along thestarboard side 95 meters from the forward perpendicular. This elevator services Weapons Magazine 1, Deck 6, andHangar Deck 2. Weapons from WE2 are transferred to WE1 on Deck 6 and continue up to HD2.4.1.6 Other Primary Arrangement ConsiderationsMain engines use side air intakes and exhausts as shown in Figure 33. This is specified in the Concept Baselinecharacteristics, Table 32. This minimizes the impact on available area in the hangar decks and recovery deck. Theside intakes and exhausts use louvered panels with a plenum to prevent water entry and maintain the 10 degreetumblehome.
