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 as follows: Subdiv-subdivision Div-this division Squad-squadron Group/flot-group/flotilla Example: Div—this 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 signs: Examples: R Squad p7—Carrier Squadron 7 D Group/Flot p3—Destroyer 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 FLOT/GROUP p1. 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. Example: Squad D—Commander this destroyer squadron Group/Flot CDp2—Commander crusier destroyer group/flotilla 2 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. Examples: Subdiv Rp6p9—USS Eisenhower Subdivision Rp6p9 Subdiv—Commander Eisenhower Subdivision 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 p0p5p2. To call the commander of the unit indicated, pennant 0 may be used preceding the unit indicator call signs. Similarly, to address subordinate commanders, p0p0 is used. A message to all squadron commanders under a group commander could use the call sign p0p0 SQUAD. 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 p2D. 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. 3-13
