In addition to the operator controllers located at
each access door and the 2nd deck main controller, a
portable main controller may be used at the main deck
level. Normally, there is one IWHS installed forward to
service the forward-magazine group and one installed
aft to service the aft-magazine group. These elevators
support the Improved Rearming Rate Program (IRRP).
UPPER-STAGE
HYDRAULIC
ELEVA-
TORS.—Upper-stage hydraulic elevators (fig. 11-12)
are used to transport weapons between the second deck
and the main deck only. The major components of each
elevator are an enclosed, watertight, vertical trunk, an
elevator platform assembly, a hydraulic power plant
system, and a semiautomatic elevator control system.
