Three main machinery rooms and one auxiliary machinery room contain thediesel propulsion engines and ship service generators. Other mechanical and electrical systems including airconditioning, distillers, firemain, etc., are fit in remaining space. These machinery rooms are spaced as evenly aspossible about the LCB to aid in balancing the ship and as far apart as possible for survivability. These rooms arepositioned as low as possible for overall ship stability. The intake and exhaust ducts for each machinery room exitthe side of the ship just below the recovery deck. The intake and exhaust locations are chosen to minimize the arealost to ducting through the ship.CUVX-HI3 has four weapons magazines located on the lowest deck of the ship enclosed by the ADH. Themagazines store the aircraft weapons and ship weapons. Each magazine spans the breadth of the ship within theADH to meet volume requirements. The magazines are separated by the main machinery rooms and are staggeredalong the length of the ship for better ship survivability.Living area requirements are estimated based on crew size using the ship synthesis model. The model estimatesareas for enlisted living, officer living, mess areas, and human support facilities. Living areas are located primarilyin the forward half of the ship and placed in close proximity to messing spaces and other human support spaces tosimplify the flow of day-to-day traffic. Some enlisted and officer berthing is located aft for separation andsurvivability.Ship support spaces are located throughout the ship. Each department requires its own support facilities;therefore support facilities are located close to the individual department location. Ship support looks after the dayto-dayoperations of the ship, such as administration, maintenance, stores handling, damage control, etc.Mission Support areas are primarily in the forward part of the ship where the command and control operationstake place. These areas include the pilothouse, flight operations control, and CIC.All tankage for CUVX-HI3 is located in the ADH. Having the tankage in the ADH puts the weight associatedwith the ships fuel, oil, etc., as low as possible, which helps the stability and seakeeping of the ship. Table 40 liststhe required and actual tankage for CUVX-HI3. Propulsion fuel tanks are located in the ADH sections surroundingthe machinery rooms for easier transfer of fuel to the engines. Ballast tanks are placed in the extreme fore and aft ofthe ship. This requires less volume to correct trim or heel conditions.Main passageways are located against the hull and run longitudinally from the bow of the ship to the hangardecks. This provides a buffer space near the hull to reduce personnel casualties and damage in the event of aweapons strike. Secondary passageways run transversely through the ship and are positioned just behind thewatertight bulkheads. Passageways are only required above the damage control deck. Main Passageways are 2meters wide and secondary passageways are 1.2 meters wide. All main passageways have watertight doors locatedat the watertight bulkheads. Below the damage control deck there is no longitudinal access to compartments.Ladders provide vertical access through watertight hatches to the damage control deck and the main passageways.Main passageways can be seen on the third deck in Figure 71 and Drawing D4.Figure 71. Main and Secondary Passageways on Third Deck4.9.4 External ArrangementsThe most important criteria for external arrangements are Radar Cross Section, aircraft operations and combatsystems effectiveness. All sides of the hull, above the waterline, are angled in at ten degrees from the vertical. Theten-degree angle is also included in the design of the AEM located on the recovery deck.The AEM is positioned at the forward starboard end of the recovery deck. This location was selected to keepthe stern of the ship open for incoming aircraft to land. It is positioned on the starboard edge to allow clearance for
