Overall  control  and  coordination  are  vested in  the  executive  officer.  The  executive  officer usually holds a meeting of department heads, at which  time  the  responsibilities  of  each  are  out- lined. The detailed planning and the day-to-day coordination  with  other  departments  are  then  nor- mally  turned  over  to  the  supply  officer.  There- after,  the  executive  officer  is  kept  informed  of progress in planning and takes an active part only if difficulties arise that cannot be handled at the lower  level.  During  the  replenishment  the  ex- ecutive  officer  remains  on  the  bridge,  and  the supply  officer  is  in  charge  of  the  movement  of stores  once  they  are  received. While several departments other than supply are actually concerned with replenishment, only weapons  and  air  departments  visibly  take  part. These   departments   are   discussed   separately. Operations  is  responsible  for  mail  being  trans- ferred  and  for  transfer  of  personnel  when  re- quired.   Engineering   personnel   man   elevator pumprooms, grant permission to open hatches as required, transfer movies, and make sure sound- powered  telephones  are  available  and  working. The  aircraft  intermediate  maintenance  department is responsible for maintaining forklifts and other materials-handling   equipment.   Although   they have  additional  duties  when  transfer  of  fuel  or gasoline  is  involved,  these  operations  are  not  a direct  concern  of  the  SK. WEAPONS The  weapons  department  normally  has  a representative  attend  at  least  one  of  the  later planning  conferences  discussing  replenishment. This   department   is   responsible   for   physically loading the material on board the receiving ship (except  during  vertical  replenishment),  for  enforc- ing  all  safety  precautions  at  replenishment  sta- tions, and for making sure all nets, slings, pallets, and  other  handling  material  belonging  to  the delivering ship are returned. If weapons depart- ment elevators are used in striking stores below, weapons  department  personnel  operate  them.  The weapons department representative is primarily concerned with the number of tons to be received and the rate at which the material comes aboard. AIR The   air   department   representative   to   the planning  conference  is  mainly  interested  in  the amount  of  clear  deck  space  required  and  the elevators that must be manned. During vertical replenishment  operations,  air  department  person- nel  also  provide  direction  to  the  helicopter  in spotting  each  net  load. REPLENISHMENT  PROCEDURES Replenishment   procedures   encompass   several areas that require a senior SK’s knowledge and attention. These areas of required knowledge in- clude  the  different  stations  used  during  replenish- ment,  the  personnel  required,  the  equipment  to be used, and the actual procedures used for the receiving,  strikedown,  and  transfer  of  account- ability. Replenishment  Stations A replenishment station is any location where some  significant  action  is  taken  on  the  stores being  received.  The  station  can  be  divided  into three   general   groups—receiving,   sorting,   and striking. Stations within a group cover the same function  regardless  of  location. Figure  7-1  shows  the  location  of  replenishment stations on a typical large carrier. Receiving sta- tions No. 1 and No. 2 are on elevators No. 1 and No. 3 respectively; the elevators being at hangar deck level. The third receiving station, normally used during vertical replenishment operations, is on or in the vicinity of the No. 2 elevator. Your newer  aircraft  carriers  will  have  four  elevators. Sorting stations are close to the receiving sta- tions where net loads may be towed by tractor or delivered  on  roller  conveyors.  At  this  point,  stores are sorted and palletized on the basis of strike area (station).  Figure  7-1  shows  major  strike  areas where  mechanical  equipment  is  available;  how- ever, strike areas are located anywhere in close proximity of the ultimate storage area of signifi- cant  amounts  of  materials. RECEIVING STATIONS.—  The first group includes  all  the  receiving  stations,  the  sites  where the  material  first  lands  when  it  is  received  on board. Most receiving stations are located on the hangar  deck.  Ship  designs  vary,  even  within  a class, with consequent variations in number and locations  of  receiving  stations. Elevators No. 1 and No. 3 remain lowered to hangar  deck  level;  helicopter  receipts  are  received on elevator No. 2 at flight deck level. The use of elevators  as  receiving  stations  is  advantageous  in that  adequate  space  is  available  for  handling stores. Material is under the control of the weapons department  (air  department  in  the  case  of  vertical 7-10
