predetermined speed. In most cases, the replenishment ship maintains its course and speed while the other ship(s) maneuver(s) into position alongside. A separation of about 100 feet is maintained between ships, with the replenishing ship frequently serving ships both to port and starboard. Messenger lines are passed to the receiving ships, which send back telephone and distance measuring lines and then haul over cargo-handling gear or fuel hoses by means of the messengers. Ships designed for that purpose do most of the replenishment, but major combatant ships are capable of refueling smaller ships. Even the smallest ships can, and do, transfer light freight, mail, and personnel by means of highlines. In   addition   to   the   standard   replenishment capabilities, all recently constructed, as well as many of the older auxiliary, ships have helicopter platforms for the transfer of munitions, personnel, cargo, and stores by  vertical  replenishment.  Vertical  replenishment permits a receiving ship to remain on station in combat formation,  eliminating  the  necessity  of  temporarily immobilizing itself by going alongside another ship for replenishment. Ammunition Ships.—Ammunition  ships  (AEs) (fig. 8-33) operate with replenishment groups to deliver ammunition and missiles to the fleet at sea. Their design incorporates  a  mechanical  handling  system  for  more rapid  loading  and  off-loading  of  ammunition.  The mechanical handling system includes such equipment as  dual-cantilevered  elevators  in  the  holds;  forklift trucks; and low-lift, power-operated transporters on the main deck for handling palletized ammunition from the elevators  to  the  transfer  stations.  Universal  portable metal dunnage provides maximum stowage with ready access to all types of ammunition. A tension highline system is built into the design along with new, improved electro-hydraulic  cargo  winches  for  replenishment  at sea. These improvements provide for much more rapid and reliable transfers and conservation of deck space. These ships are capable of handling all types of missiles (fig. 8-34). Oilers and Tankers.—Oilers  (AOs),  carrying Navy  fuel  oil,  jet  fuel,  and  other  petroleum  products, operate  with  replenishment  groups  and  deliver  their cargo to ships at sea. Oilers, as well as ammunition ships (fig.  8-35),  can  service  ships  on  both  sides  simulta- neously. The  AO  (Jumbo)  is  a  conversion  of  the  AO  that includes the installation of a new midsection in the hull. This midsection increases the payload and provides for an improved balance of cargo fuel products to meet the more  recent  demands  placed  upon  the  AO  by  the increase in fleet requirements for jet aircraft fuel. 8-28 Student Notes: Photograph courtesy of PH3 Jason Branson Figure 8-33.—USS John C. Stennis (CVN 74) off-loads ammunition onto ammunition ship USS Mount Hood (AE 29).
