of the NAVSUP 1250-1, and distribute the
remaining copies by the established procedures.
When materiel is authorized to be requisi-
tioned by message and no exception data is
required, prepare message requisitions for NSN
and NICN items for transmittal through the
Defense Automatic Addressing System (DAAS).
DAAS is a real-time random access digital com-
puter system that uses the Automatic Digital
Network (AUTODIN) switching centers of the
Defense Communications System to receive and
automatically retransmit MILSTRIP messages to
the proper addressees. An input message to
DAAS may include multiple requisitions, follow-
ups, requisition modifiers, and cancellation
requests, provided that each document included
in the message is limited to 66 CCs of data as
illustrated in figure 12-11.
Prepare message requisitions for non-NSN
and NICN items or items requiring exception
data as shown in figure 12-12. Submit these re-
quisitions in MILSTRIP format; separate
data elements by slants (/); and identify data
elements that are not applicable by BLNK.
A message requisition for non-NSN and NICN
items may contain no more than seven requisi-
tions, and they must have the same routing
identifier. For detailed instructions on message
requisitions, see NAVSUP P-485.
Purchase actions are normally taken by a
shore activity as a result of ships requisitions.
However, ships supply officers and commanding
officers of ships without Supply Corps officers
may get emergency supplies or services by
purchasing them on the open market when all of
the following conditions exist:
. There is an immediate and urgent require-
ment for authorized supplies or services.
. The supplies or services are not available
at the local supply activity.
l Time is of the essence and scheduled opera-
tions will not permit procurement through Navy
shore-based purchasing activities. Other purchase
restrictions may be imposed by the senior officer
present afloat (SOPA), particularly in foreign
When authorized by TYCOM, the supply
officer may make routine purchases of supplies
