For example, the visual call sign of USS Fanning
(FF 1076) is Fp1p0p7p6; of USS Forrestal (CV 59),
Rp5p9; of USS England (CG 22), Cp2p2.
If it happens that visual calls are the same for two
or more ships in company or in the same port, their
international call signs are used.
SHORTENED VISUAL CALLS.Shortened
visual calls are constructed by omitting unnecessary
numbers. If the Alamo (LSD 33) were the only
amphibious-type ship in the vicinity with the final
digit of its hull as 3, its visual call would be Lp3.
UNIT INDICATOR CALL SIGNS.Call
signs for organized groups/flotillas, squadrons,
divisions, and subdivisions of ships are constructed
Example: Divthis division
By using the appropriate unit pennant with a type
indicator preceding the unit pennant and numeral
pennants following, you form the following visual call
Examples: R Squad p7Carrier Squadron 7
D Group/Flot p3Destroyer Group/Flot 3
In calling commands and ships in the same unit,
the unit indicator may be used alone. Thus, DIV alone
would be the call for this division.
Type indicators may be omitted from call signs
if no confusion could result. If cruiser-destroyer
group 1 were in port with no other ship group 1
present, the call for CruDesGru 1 could be
To form the visual call sign of the commanders of
an organized group/flotilla, squadron, division or
subdivision of ships the unit indicator is followed by
the type indicator.

Group/Flot CDp2Commander crusier destroyer
Call signs for a group of ships associated with
an individual ship that is not organized as a task
unit or element is constructed by prefixing
Subdiv to the call sign of the identifying ship. The
command call is constructed by prefixing the
ship's call to Subdiv.

NUMERAL PENNANT CALL SIGNS.
Listed in figure 3-6 are numeral pennant call signs for
general use in tactical organizations. To form the call
sign for the commander of one of these groups or units,
precede the listed call with pennant 0. Thus, Entering
or leaving harbor group No. 2" is p5p2. This call
includes all units of the group, as well as the
commander and subordinate commanders. To address
only the commander of the group, the call sign is
To call the commander of the unit indicated,
pennant 0 may be used preceding the unit indicator
Similarly, to address subordinate commanders,
p0p0 is used. A message to all squadron commanders
under a group commander could use the call sign p0p0
Other numeral pennant call signs may be used
with type indicators to designate the type of ships in a
unit. The call sign for all destroyers, for instance, is
SPECIAL TASK ORGANIZATION CALLS.
Visual call signs employing numeral flags and
numeral pennants are used only in flaghoist
communications within task organizations. These call
signs always begin with a numeral flag followed by
numeral pennant(s) that indicate the number of the
task organization. Type indicator may be used
following the call sign.
