USAF VOICE CALL SIGN INSTRUCTIONS

AFKAO-LG, 11 May 1982, is supplemented as follows and applies to HQ North
American Aerospace Defense Command (NORAD), the regions, and subordinate units
under the operational control of Commander in Chief, NORAD (CINCNORAD):

1-ld(Added). Application of Voice Call-Signs in NORAD Subordinate Units:

(1) Aircraft changing voice call-signs assigned in AFKAI-1, sections A
and D, are used by aircraft under the operational control of CINCNORAD for
movements outside of the local ARTCC area, according to the basic regulation.
Exceptions are authorized as follows:

(a) NORAD alert fighters flying an active air defense mission use
the daily changing call-sign assigned in AFKAI-1, section A or D, at all defense
conditions (DEFCON). Alert aircraft flying continuation training sorties are
authorized to use their squadron static call-sign. One of the spare fighter
line numbers, assigned each air defense sector, in AFKAI-1, section A, may be
assigned to alert fighters at the discretion of the sector commander.

(b) E-3's under the operational control (OPCON) of CINCNORAD for
daily training use their normal static call-signs located in AFKAI-1, sections E
or H. E-3's executing a NORAD OPLAN use call-signs designated in AFKAI-1, sec-
tions A and I.

(2) Regions or Sectors will ensure that individual AFKAI-1 block or
line numbers are assigned if more than one E-3 is operating under their OPCON or
tactical control (TACON). Request additional block or line numbers from HQ
NORAD, Command, Control and Communications Division (J3AC), if required. If
operational requirements dictate that an E-3 cross region or sector boundaries,
it maintains the same call-sign and continues to use the same block or line for
any required call-sign changes throughout the mission.

(3) Use static call-signs assigned in AFKAI-1, sections E and H, for
missions such as "faker" and "target" only when flying those type missions,

(4) Use the staff position call-sign assigned in AFKAI-1, section J, to
conceal the identity of key personnel and especially when traveling by aircraft.
Do not use these voice call-signs for aircraft clearance purposes or as aircraft
call-signs.

(5) At DEFCONs 5 and 4, NORAD command and control facilities use static
voice call-signs assigned in AFKAI-1, section M. At DEFCON 3 or when directed
by higher authority, use changing voice call-signs in AFKAI-1, sections I or L.

(a) Do not use voice call-signs to identify telephone switch-
boards. Switchboard operators at region level or higher use their numerical
unit identifications followed by the word "switch." Below region level, use
place names to identify switchboards.

(b) Identify fighter squadron alert centers by their unit d designations.

(6) NORAD fighter forces not on alert use their squadron static call-
sign.
(7) Ground or airborne units trying to contact an E-3 with an unknown
voice call-sign use the changing collective voice call-sign listed in AFYAI-1,
section I. Responses from the E-3, which uses its individual changing voice
call-sign, are confirmed with the AFKAI-1, and or challenged with the AKAA-2001.

(8) The static, collective voice call-sign "BOX CAMERA" is reserved for
wartime contact with NORAD E-3s when an AFKAI-1 is not available or when a unit
is communications isolated. Any E-3 receiving such a call responds and
challenges with the AKAA-2001.

3-5a. Assignment of Call-Sign Suffixes:

(1) Units assigned call-signs in AFKAI-1, sections A through H, are
authorized to assign suffixes from the digits 01 through 99 for the following
reasons:

(a) Active air defense missions.

(b) Counternarcotics missions.

(c) Intercept training.

(d) Deployment for NORAD air defense exercises.

(e) Fighter aircraft other than those listed above, but flown
wholly or in part within the NORAD air defense environment; such as functional
check flights, proficiency flights, student training, and local training or
familiarization flights.

(2) At DEFCON 3 or when directed by higher authority, use the changing
voice call-signs listed in AFKAI-1, section I, to contact the E-3 Battle Staff
(BS) or the NORAD Airborne Battle Staff (NABS). Use the following position
suffixes:

(a) 01 - NORAD airborne battle commander (NABS).

(b) 02 - Battle director (NABS/BS).

AFKAO-IG/N Sup 1 13 August 1990 3

(c) 03 - Weapons resource officer (NABS).

(d) 04 - Battle director technician (NABS/BS).
(3) Direct any requirement for letter suffixes to support call-signs in
AFKAI-1, sections J through M, to HQ NORAD, Command, Control and Communications
Division.

3-6b. Similar Sounding or Confusing Call-Signs. Notify HQ NORAD, Command,
Control and Communications Division, of word conflicts, objectionable words, or
words unsuitable for operational use. State only block and line number, not the
word. Temporary use of an unassigned command call-sign is authorized if
required after normal duty hours, or has an immediate operational requirement.
Report this action to HQ NORAD CHEYENNE MTN AFB CO//J3A/J3AC// by immediate
precedence message.

3-8. Use of Aircraft Call-Signs During a Change Period:

a. Alert fighters flying a continuation training sortie and diverted to an
active air defense mission retain the call-sign filed at takeoff.

b. At DEFCON 3 or higher, all NORAD fighter forces use AFKAI-1 changing
call-signs.

c. At all DEFCONS, airborne fighter forces maintain the call-sign filed at
takeoff, even over a zulu day change period.

d. At all DEFCONS, E-3 mission crews and battle staffs change call-signs ac-
cording to AFKAI-1 procedures.

e. At DEFCONs 5 and 4, E-3 flight crews maintain the call-sign filed with
ATC throughout the mission. At DEFCON 3 or higher, E-3 flight crews change
call-signs according to AFKAI-1 procedures.

3-15. Communications Compromise of Call-Signs. Report compromises and sus-
pected compromises by immediate message to HQ NORAD, Command, Control and
Communications Division. If required, in order to protect mission operational
security (OPSEC) or communications security (COMSEC), use the procedures in
paragraph 3-6b of this supplement.

3-21. Procedures for Submitting Change Requests. Submit requests for new call-
signs, deletions, or change to HQ NORAD, Command, Control and Communications
Division, for validation and forwarding to AFCSC/OSC.
