limit  switch  actuates,  stopping  the  elevator and shutting off power to the hoisting winch. A5. Upper-stage  elevators  are  used  to  transport weapons between the 2nd and main decks. A6. IWHS  lower-stage  elevators  service  the  7th through the main decks. A7. The platform machinery for an IWHS lower-stage  elevator  is  located  on  the  3rd deck. A8. The   only   weapons   elevators   that   provide access  to  the  flight  deck  are  the  upper-stage, wire-rope elevators. A9. The  primary  responsibility  for  maintaining weapons elevators belongs to the AO rate. A10. The electrical power required to operate the weapons  elevators  is  440-volt,  three-phase, 60-Hz power. EXPLOSIVE  ANCHORAGE.—At  times,  load- ing or offloading large quantities of ammunition and explosives at the pier is not practical or feasible. For example,  a  ship  may  be  located  at  a  pier  that  has  a restricted explosive load limit due to the geographical location of other ships or occupied structures. It could also be due to the geographical location of shore-based, ammunition    handling    facilities.    For    example,    an aircraft carrier may be docked in Norfolk, Virginia, and the activity receiving or issuing the ammunition may be located in Charleston, South Carolina. In this situation, the  most  practical  method  would  be  to  locate  the aircraft  carrier  at  a  designated  explosive  anchorage (commonly  called  whiskey  anchorage)  and  transport the ordnance by lighters and/or barges. The transfer of ammunition between the ship and the lighters/barges is normally accomplished by the use of a floating crane. Even   though   a   ship   is   located   at   an   explosive anchorage,   transferring   ammunition   is   restricted   to daylight hours. Normally, the ship remains at anchorage   until   the   entire   evolution   is   completed, which may vary from 1 to 5 days. TRANSFER  OF  AMMUNITION  AT  SEA.— The transfer of ammunition at sea (underway) presents problems not met by pier-side or anchorage operations. Normally, replenishment at sea involves the transfer of fuel, supplies, stores, and ammunition simultaneously. Obviously,  available  deck  space,  available  handling equipment,  and  manpower  are  used  to  the  maximum efficiency.   Every   detail   of   the   entire   operation   is preplanned  and  coordinated  between  the  departments involved within the ship and the individuals within the departments. Conventional   replenishment   (CONREP)   and/or vertical   replenishment   (VERTREP)   methods   at   sea accomplish the transfer of ammunition. The CONREP method   consists   basically   of   a   steel   cable   rigged between  the  supply  ship  and  the  receiving  ship  at  the hangar-deck  level.  These  points  of  contact  are  called "conning  stations,"  and  there  may  be  more  than  one conning station in operation at the same time. Cargo is attached   to   the   cable   by   using   approved   handling equipment  and  conveyed  from  one  ship  to  the  other. The AO is only responsible for ammunition items. You position  each  ammunition  load  at  the  conning  station for transfer. As the ammunition loads are received at the conning  station,  you  move  the  load  to  a  designated staging  area  until  it  is  struck  below.  The  ship’s  deck department normally performs the operation of conning equipment. In the VERTREP method, helicopters using slings and/or  cargo  nets  transfer  the  ammunition  to  or  from the  supply  ship.  VERTREP  operations  are  conducted on the flight deck. Aviation Ordnancemen are responsible for handling all ammunition and preparing and  positioning  empty  slings  and  ammunition  details for    transfer    to    the    supply    ship.    Ammunition    is transferred from the flight deck to the hangar deck by a designated  aircraft  elevator.  This  elevator  is  normally on   the   port   side   when   CONREP   and   VERTREP operations are being conducted simultaneously.

Under what conditions is a pier-side weapons movement   of   ammunition   loaded   onto   an aircraft carrier? Q3. List the methods used to transfer ammunition at sea. Q4. When  VERTREP  is  being  used  to  transfer ammunition between ships, transfer is accomplished by ____________________.
