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
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
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 ships deck
In the VERTREP method, helicopters using slings
and/or cargo nets transfer the ammunition to or from
the supply ship. VERTREP operations are conducted
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.
