      1. The following methods only will be used for signalling positions in enemy reports:
        1. The table of lettered Coordinates (SP 02274) using the Air Force method. This method should always be used when working in conjunction with Coastal Command and Fleet Air Arm aircraft.
        2. Three letter self-evident groups indicating prominent places. These are listed in the British Auxiliary Vessels Signal Book (SP 02226(2)). Extracts from this publication are given in Appendix 16.

  1. Recognition and Identification.
      1. Normal methods of recognition will be in force, but in established traffic lanes are only to be used between surface craft in emergency. Light craft should not identify themselves to major war vessels in these lanes unless they have a special reason to do so,
      2. Landing craft will NOT carry recognition signals.
      3. Where extracts are issued to ships and craft, these are to cover the period of the outward and return voyage.
    1. Identification by Day

    2. The normal methods of identification may be used between surface vessels.
    3. Deck markings (SP 02298(4)) and last resort recognition signals will NOT be used.
    4. Identification by Night

    5. Between Surface Vessels - In emergency the following methods of identification may be used between surface vessels:
      1. Any normal method including VF and minor war vessels display signals.
      2. Fighting lights (including use by some coastal craft but NO landing craft).

--Sheet 4 of 9--


      1. Two-star Cartridge. (Used by Coastal Forces)

    1. Between Surface Vessels and Aircraft
    2. When a ship has established or has good reason to believe that an approaching aircraft is friendly the ship may fire the aircraft recognition cartridge in force. (This will NOT be effective unless the aircraft is within 3 miles when the cartridge is fired). The aircraft on seeing the recognition cartridge should switch on navigation lights and turn away.

    3. It is to be accepted that Leigh lights are in use by Allied aircraft only and are not used by the enemy. Allied surface craft are therefore not to engage aircraft burning Leigh lights.
    4. Should an Allied surface craft be illuminated or be in danger of being illuminated by a Leigh light aircraft, the former may fire the aircraft recognition cartridge as an identification to the aircraft.
    5. Leigh light aircraft will attack enemy E-Boats, R-Boats, W-Boats or U-Boats; they will not attack any larger surface craft unless special orders are issued.
    6. Merchant Vessels
    7. Identification will NOT be used by Merchant vessels, and the use in the English Channel of SP 02446(2) is to be suspended from D-Day.

  1. Authentication.
  2. The methods to be used for authentication are described in Appendix 4.

  3. Radio receivers of a type which radiate energy from receiving antennas will not be used during periods of radio silence. The restriction also applies to electrical equipment such as razors, etc., which may radiate outside the ship. Army radio

APPENDIX 2

 

DELIVERY GROUPS AND CALL SIGNS

 

  1. Delivery Groups.
    1. The current British system of delivery groups (SP 2489 and 2490 series) will be used. U.S. and other Allied authorities and major war vessels concerned have been allocated groups in a special addendum to the current edition of the SP 2489 series.
    2. If it is desired to send a codress message to an authority not in this book the call sign from SP 2573 is to be used as a delivery group.
    3. At a later stage in the operation the normal combined book will be used. (SP 02378 or SP 2535 and 2536)

  2. Call Signs.
    1. Two call sign books will be used:
      1. The current British book (SP 2489 and 2490) as described in paragraph 1(a) above. This system will be used on all circuits except intra-assault circuits.
      2. The European Theater Call Sign Book (SP 2573). This system is to be used on all intra-assault circuits in accordance with the instructions laid down in the book.
      3. When a plaindress message has to be passed on both extra and intra-assault force circuits, the call signs from SP 2573 are to be used on both, except for the call up, when the call signs appropriate to the circuit are to be used.

    2. Any station not allocated a major war vessel call sign will use the call sign allocated in SP 2573 on any circuit.
      1. MULBERRY tugs, smoke-making trawlers and minor war vessels and craft not allocated call signs in SP 2573 are to use their signal letters unrecoded as call signs.

    3. The normal U.S. naval call signs, enciphered, may be used BETWEEN U.S. SHIPS AND COMMANDS ONLY. If used, care must be exercised that addresses consist of U.S. organizations only.

--Sheet 1 of 12--


      1. The European Theater Call Sign Book (SP 2573) will not be carried by LCI or LCT on their first trip. Force Commanders will arrange to provide the necessary extracts from this book for the first trip. For subsequent trips this publication will be obtained from the issuing office representatives in United Kingdom ports.
      2. Voice Call Signs to be used by ships and shore stations on the VHF Simplex circuits are given in Table I.
      3. Voice Call Signs for use on voice circuits within the Western Task Force are given in Table II.
      4. On other voice circuits, the W/T call signs will be used.
      5. Fire Support Call Signs will be three letter daily changing call signs. They will be issued to Fire support ships and shore fire control parties separately.
      6. Visual Call Signs.
        1. For intra working normal visual call signs will be used.
        2. For combined use the call signs assigned in European Call Sign Book (SP 2573) will be used.

      7. The European Theater Call Sign Book contains self-evident calls for use with beach stations, boat waves, etc. These call signs are to be used as visual call signs as required.
      8. Signal letters of smoke-making trawlers and MULBERRY tugs are given in Table III.
      9. Force headquarters ships are allocated special two-letter signs (Table IV) for use on extra assault force circuits.

APPENDIX 4 - AUTHENTICATION

 

  1. On circuits external to the Assault Forces, the Combined Authentication Tables (CCBP 122A series) will be used when required. This will be held by all ships and commands which normally hold a class III or above allowance. The methods to be used are those described in Instructions for Combined Authentication System as follows:
  2. (a) Challenge and Reply - First method.
    (b) Authentication of messages - First method.

    Normally it will not be necessary to authenticate on circuits external to the Assault Forces since despatches sent on such circuits will be in high grade codes and ciphers.

  3. On Radar Reporting Wave, Authenticity Table No. 2 (SP 02551(2)) will be used. It will be placed in effect by the station controlling the circuit.
  4. On intra-assault circuits, authentication will be carried out by use of the effective "LOXO" card (SP 2538 series). The authenticator for any given message will be the code version of the time of origin of the message in question. In the case of times before 1000, the initial 0 or 00 will be disregarded. The method of coding the time of origin must be varied as much as possible. On boat control circuits & ship-shore administration circuits, the method of authentication will be prescribed by Assault Force Commanders.
  5. Illustrations of cases in which messages on Intra-Assault Force circuits may be authenticated follow:
    1. When operational orders or requests are made in plain language:
    2. Example:
      20 v BG - 261136B = SEND IN GROUP 12 NOW ALN MQR = K
      (ALN is assumed to be the code group for "11" and MQR that for "36" to give T.O.O. 1136.)

    3. When messages in plain language cancel or correct previous orders:
    4. Example:
      20 v BG - 261217B = CANCEL MY 1136 PZN RQG = K
      (PZN is assumed to be the code group for "121" and RQG that for "7" in T.O.O. 1217.)

    5. When it is desired to confirm a message or Signal that is suspected of being bogus. In this case:
      1. The suspicious addressee is to control the transmitting station to authenticate by making (by R/T or W/T) the word "BANKO" followed by the Date Time Group or Time of Origin of the message concerned.

--Sheet 1 of 2--


        Example:
        1BG is suspicious of the following message which has a date time group 261256B.
        "20 1BG v BG - 261256B = BEACH SIGNAL STATION ESTABLISHED = "K"

        1BG then makes:
        "BG v 1BG 261305B = BANKO 261256 = K."
        (261256 being the date time group of the suspected message).

      1. The originator (if bona fide) is then to reply, giving the correct "LOXO" group for the Time of Origin of his fresh message.
      2. Example (following on example in "i"):
        BG will make - "1BG v BG - 261325B = MY 261256 XRN PAL = K."
        (XRN PAL being taken as the code groups for 1325, the T.O.O. of the new message.)

      3. If the originator on being raised as in "i"fails to authenticate or passes the wrong group, the challenging station is immediately to inform all other addressees as follows:
        1. T.O.O. of bogus message.
        2. Word "DUDD".
        3. Code groups authenticating his own message, thus - "20 BG v 1BG - 261356A = 261256 DUDD XAL MQR = K."
          (XAL and MQR are assumed to be the correct code groups for "1356" the T.O.O. of the new message.)

    1. In all messages transmitted on the Joint Force Broadcast.
    2. In the case of bogus messages being passed from an authentic Call Sign, the rightful owner of this Call Sign is, either on hearing the bogus station or on hearing the message challenged, to make a "DUDD" message as in (c)(iii).
    3. "DUDD" messages must always be authenticated by the originator.
    4. To summarize, all authentication groups are always the coded times of origin of the message in which they are sent.

  1. The above method of authentication will be memorized and will NOT be carried in ships or craft beaching. Special care will be taken to destroy it if a ship is lost.

APPENDIX 5

COMMUNICATIONS IN CAPTURED BEACH AREAS

 

  1. General Information.
    1. During the assault the joint assault signal companies will establish the beach communications required for the assault and immediate follow up period. After the beachhead is secured, two beach communication centers will be established, one on beach OMAHA and one on beach UTAH. These communication centers will provide facilities for NOIC OMAHA and NOIC UTAH respectively. Off beach OMAHA will be constructed an artificial harbor known as MULBERRY "A". Off beach OMAHA and UTAH there will be breakwaters constructed of sunken merchant ships. These are called GOOSEBERRIES.
    2. Radar equipment will be landed and established on the western flank of beach UTAH by D plus 1 day. This radar is to give warning of "E" boats and low flying aircraft.
    3. As the operation progresses all naval organizations on the far shore will be placed under the command of a Flag Officer (short title FOWEST). Additional equipment will be landed and signal and radio stations established to provide facilities for FOWEST by D plus 8 day.
    4. The Far Shore Shuttle Service for the control of convoys will initially be operated under the Naval Commander Western Task Force, and later will be placed under the control of FOWEST.
    5. The Naval Commander Western Task Force will be radio guard for FOWEST until such time as FOWEST is established either afloat in the assault area or ashore.

  2. Radio Frequencies.
  3. The frequencies to be guarded by the stations in the captured beach areas are given in tables I and II of appendix 3, the Radio Frequency Plan. As land line facilities become available radio watches will be reduced as ordered by the Senior Officer Present Ashore. The necessary ship to shore channels will be continuously guarded however.

  4. Cryptographic Aids.
  5. The cryptographic aids to be held by activities in captured beach areas are given in appendix 1. During the early stages of the operation only low grade systems will be held. These will be increased by the addition of the CCK and ECK as security permits.

  6. Call Signs.
  7. Call signs assigned for the assault will be used in the early stages of the operation. After the establishment of shore facilities the following call signs will be in effect:

    NJI - FOWEST NJI2 - NOIC UTAH
    NJI1 - NOIC OMAHA NJI3 - MULBERRY "A"

--Sheet 2 of 2--


 

APPENDIX 7

COMMUNICATIONS FOR FIRE SUPPORT SHIPS

 

  1. Command Circuits.
  2. Fire support ships which are not assigned to an assault force will guard the Western Task Force auxiliary wave. Fire support ships assigned to an assault force will guard the assault force auxiliary wave. These circuits will be used for passing information or instructions to fire support ships.

  3. Communications with Shore Fire Control Parties.
    1. The shore fire control parties in he Western task Force will be numbered from 1 to 50.
    2. Bombardment frequencies will be allocated to Assault Force Commanders who will further assign such frequencies to the shore fire control parties. In the Western task Force each party will have two frequencies assigned:
    3. (1) A high frequency for use with the SCR 284 equipment.
      (2) A VHF frequency for use with the SCR 609 equipment.

    4. A ship ordered to work with a designated fore control party will set watch on the appropriate frequency and establish communication.
    5. The VHF FM equipment (SCR 608/9) will be used as long as the shore fire control party is operating within the range of the equipment. Outside this range the SCR 284 equipment will be used.
    6. One frequency has been assigned each assault force for use as a bombardment calling wave. This may be used by any SFCP to communicate with the Assault Force Commander and request support. The SFCP will remain on this frequency to receive information as to the type of ship assigned.
    7. The system of call signs to be used is described in Annex "D".

  4. Spotting Aircraft.
    1. Twenty-four VHF frequencies have been assigned for use with spotting aircraft. Each of these frequencies will be associated with a voice call sign. Frequencies and call signs are listed in Table I.
    2. Bombarding ships will set watch on the frequency assigned her spotting aircraft and establish communication using the associated call signs. The ship's call sign will be that of her spotting plane followed by the codeword "TURRET". If an aircraft is spotting for two ships the second ship will use the call sign of her spotting aircraft followed by "SPUNYARN".

--Sheet 1 of 2--


    1. Bombing ships will carry a complete set of crystals for all 24 frequencies in order to shift as necessary.
    2. Each spotting aircraft will carry a transmitter equipped with crystals for the following:
      1. Spotting frequency
      2. Spotting aircraft guard (Reconnaissance frequency) if detailed.
      3. Air - sea rescue.

    3. Requests for spotting aircraft will be made by despatch to the Allied Naval Commander in Chief and the Naval Commander Western task Force through the normal channels indicating:
      1. The target to be engaged.
      2. The aircraft call sign, and hence the frequency, proposed.
      3. The firing ship, if known.
      4. Headquarters ships will keep a continuous watch on the Reconnaissance Frequency and may be called on it by spotting aircraft in an emergency.

  1. Communication With Support Craft.
  2. Communication with support craft will be as directed by Assault Force Commanders.

  3. Cryptographic Aids.
    1. The AEF Assault Signal Book is the normal system to be used for bombardment communication.
    2. In addition, shore fire control parties will carry SLIDEX for more secure communication. SLIDEX should be used for passing those portions of information messages in which security is required. This system should not be used in making calls for fire support.

  4. Authentication
    1. The following form of authentication may be used between SFCP's and bombardment ships:

--Sheet 2 of 2--


      1. The SFCP will make the call sign in the usual manner in conjunction with the Fire Control Code as set out in the Assault Signal Book.
      2. The bombarding ship may repeat the signal in full if ordered, adding the word "BANKO" at the end of the message, if authentication is desired.
      3. The SFCP will then repeat the time of origin of the original in SLIDEX.

  1. Grids
    1. The following grids may be used for indicating targets which are not specially designated in advance.
      1. Local military grid (always to be used with spotting aircraft).
      2. Gridded oblique photographs.
      3. NOTE: THE HOME FIGHTER GRID IS NOT IN ANY CIRCUMSTANCES TO BE USED FOR INDICATING TARGETS OR POSITIONS ON THE GROUND.

  2. Aircraft Spotting Frequencies.
  3. Each aircraft frequency will be associated with its voice call sign. In the case of relief aircraft, this call sign will be followed by a number indicating the relief number of the aircraft.

APPENDIX 8

RADAR AND AIR WARNING

 

  1. Types of Radar.
  2. The type of radar equipment installed in U.S. ships and the British equivalent equipments are classified below:

    Description British United States
    Surface warning 271, 272, 276 SG, SO
    Air warning 279, 281 SA, SC, SK
    Combined 286, 291 SL
    Gunnery GA, GB, GC, GS Mark III, IV, XI, XIV

  3. Radar Silence.
    1. Upon sailing from the United Kingdom and until after surprise is lost in the initial assault radar silence will be in effect. During radar silence the following conditions apply:
      1. No radar transmissions except from surface warning sets as essential to the conduct of the assault. Such use should be limited and intermittent.
      2. Combined warning sets operating on frequencies above 3000 mcs. may be used in the same manner as surface warning sets.
      3. Other radars may be used for listening watches for enemy transmissions or radar counter measures.

    2. After surprise has been lost there will be no restriction on the use of radar in the assault area. Outside the assault area there will be no restrictions on the use of radar during good visibility in daylight. At night or during periods of bad visibility the use of radar should be determined by the tactical situation obtaining. Normally under these conditions restrictions on the use of surface radar will not be necessary.
    3. Some surprise as to the location of the assault may be preserved up to arrival in the transport area. Radar silence should be preserved until nautical twilight or counter action by enemy ships, craft, or shore defenses, whichever occur first.

  4. Operation of Fire Control Radar Equipments.
    1. The operation of fire control radar equipments will conform to the restrictions of paragraph 2 regarding radar silence. The equipments should be kept warmed up and ready for use.

--Sheet 1 of 8--


    1. After the loss of surprise there will be no restriction on the use of fire control radar.

  1. Operation of Surface Warning Radars.
  2. After the loss of surprise, there will be no restriction on the use of surface warning radars. Contacts of enemy surface craft by surface radar should be handled as ordinary enemy contact reports. Low flying aircraft detected by this type of radar should be reported over the radar reporting wave.

  3. Operation of Air Warning Radar.
    1. In the Western Assault Area the operation of air warning radar will be coordinated by Commander Force "O" who will assign the radar guard ships, keep the air plots required, and control the air warning broadcast to the Western Task Force. Commander Force "U" and the Commanding Officer, USS HENRICO, are the first and second reliefs respectively for this duty and, if necessary, will take over the operation of air warning radar in the order named.
    2. Radar guardships will report unidentified aircraft over the naval radar reporting wave using the procedure prescribed in the Combined Air Warning Code (CCBP 10).
    3. Raid letters assigned certain vessels to be used for reporting in accordance with the above instructions are given in Table I.

  4. Procedure on Air Warning Circuit.
    1. The purpose of the Air Warning Circuit is to broadcast vital raid information in the shortest possible time. Three types of raid warnings will be broadcast on this circuit:
      1. General air raid warning of hostile or unidentified planes.
      2. Specific air raid warning giving available details of raid.
      3. Warning of raids by E-boats or other surface craft.

    2. General air raid warning will be broadcast by the ships controlling the air warning circuit when one or more hostile or unidentified aircraft are within 25 miles of the assault area. The warning will be given in this form:

--Sheet 2 of 8--


      Example: "THIS IS YOKE - WARNING RED - I SAY AGAIN - WARNING RED - OUT"
      Meaning: Air raid warning from USS ANCON - One or more hostile or unidentified planes within 25 miles of assault area.

    1. Specific air raid warnings will be compiled from information received from radar guardships and from broadcasts received from the United Kingdom and radar stations on the continent. Grids will not be used. Instead a true bearing and distance from the ship controlling the broadcast will be used. The sequence of the text will be as follows:
    2. (1) Raid Letter - Letter assigned controlling ship
      (2) Raid number - 1 to 99
      (3) Size of Raid - "ONE", "FEW", "MANY" for more than five.
      (4) Altitude - "LOW" under 3,000 feet
      "HIGH" 5,000 - 10,000 feet
      "VERY HIGH" over 10,000 feet
      "HAZY" unknown.
      (5) Identity - "CHICKEN" friendly
      "BANDIT" hostile
      "BOGEY" unidentified
      (6) Bearing from ship - "BEARING" plus three numerals
      (7) Distance from ship - "DISTANCE" plus number of miles
      (8) Time of plot - "TIME" followed by two numerals, minutes of the hour
      (9) Authenticator - "LOXO" Code of time of Plot

      Example: "This is Yoke seven - this is Yoke seven - many high bandits bearing one five nine distance two seven miles, time three seven, xray, zebra fox - repeat"
      Meaning: Air warning message number seven from USS ANCON - more than five hostile aircraft, flying over 10,000 feet bearing 159 true distant 27 miles from ANCON, time of plot thirty-seven of current hour. XZF authenticator.

--Sheet 3 of 8--


      The warning is canceled as follows:

      Example: This is Yoke clearing seven time four five fox fox king and repeat.
      Meaning: ANCON now cancelling raid warning number seven at forty-five minutes of the hour FFK authenticator.

    1. Warnings of E-boats or other fast surface craft will be made using the code words listed in Appendix 16. The form of the warning will be as follows:
    2. Example: "This is XRay - INFLUENZA WEST - repeat"
      Meaning: AUGUSTA broadcasting a warning - E boats are operating within fifteen miles of the Western Task Force Area.

    3. Ships not assigned raid letters will use the voice call signs designated in Appendix 2 if required to initiate raid warnings.

  1. Operation of I.F.F. Equipment.
    1. It is recognized that unrestricted use of Interrogators and Transponders (I.F.F. set) in the congested conditions pertaining in NEPTUNE would result in breakdown of the I.F.F. identification system due to technical limitations of the equipment involved. The rules laid down in C.B. 04092/44 will, therefore, (except as in para. 18 below) be in abeyance until further orders in he following areas:
      1. For Interrogators: between Lat. 45°N and 52°N, and Long. 6°W and 8°E.
      2. For Transponders: between Lat. 45°N and 54°N, and Long. 6°W and 8°E.

    2. New rules will govern the use of I.F.F. equipment by all services in the above areas from sunset of D-1 or as promulgated by signal. The rules which are of direct concern to Naval Forces are outlined below and it should be noted that the resulting limitations will allow identification of friendly units by I.F.F. to be made in only a small percentage of all possible cases.
    3. Rules governing use of SHIPBORNE INTERROGATORS types BL, BN, 242, 243 and 244 are as follows:

--Sheet 4 of 8--


      1. Use of omni-directional interrogators in the assault area is banned. This restricts the use of types BN, a few BL and 242 fitted to W.C. sets within the area defined in ON. 1, para. 6.
      2. Use of other Interrogators in the assault area for identification of aircraft is to be confined to:
        1. Task and Assault Force H.Q. ships,
        2. Fighter Direction Tenders,
        3. Ships performing fighter direction duties,
        4. Ships ordered to pass reports on the Naval Radar Reporting Wave.

      3. Use of all Interrogators outside the assault area for identification of aircraft is to be confined to:
        1. Ships detached or operating singly.
        2. Interrogator Guardships for groups of ships, on the basis of not more than one guardship per unit, to be detailed by the Senior Officer Present.

      4. Use of Interrogators for intership identification may be made by any ship when surface visibility is less than 10 miles, subject to the restrictions in (i) above.
      5. When employed as in (ii), (iii) or (iv) Interrogators may transmit:
        1. Only for the absolute minimum period required to identify a new detection.
        2. Only when ordered by Plot or Bridge and not at the discretion of the radar operator.

      Plotting officers are to pay particular attention to continuous tracking of plots in order to minimize the necessity for re-interrogating old detections.

    1. Rules governing AIRBORNE TRANSPONDERS (I.F.F.) are as follows:
      1. By night (sunset to sunrise) I.F.F. will be shown only by:
        1. night fighters,
        2. Coastal Command aircraft,
        3. aircraft in distress.

--Sheet 5 of 8--


        NOTE: I.F.F. WILL NOT BE SHOWN BY FRIENDLY NIGHT BOMBERS AND AIRCRAFT OF AIRBORNE FORCES, EXCEPT WHEN IN DISTRESS.

      1. By day, transponders may be used only by:
        1. one aircraft in each fighter formation at the discretion of the land or seaborne Controller
        2. Coastal Command aircraft
        3. air craft detailed to cooperate with ships
        4. aircraft in distress.

    1. Rules governing USE OF TRANSPONDERS (types 251M, ABK/BK and 253) by ships are as follows:
      1. When surface visibility is less than 10 miles transponders may be used by:
        1. ships detached or operating singly,
        2. I.F.F. Guardships for ship groups, detailed by the Senior Officer present on the basis of not more than one guardship per thirty ships or part thereof.
        3. [There was no entry for sub-section "c" in the source document. - HyperWar Editor]
        4. Units ordered by shore authorities to remain on established patrols in circumstances when they are in position and certain that their navigation is accurate (e.g. when using QH) may be instructed to switch off transponders. They must however be ready if ordered by signal, or if they leave their positions to switch them on immediately.

      2. Transponders may be used without restrictions by any ship when,
        1. shadowing or engaging enemy units,
        2. homing aircraft, from 1 hour before ETA of aircraft,
        3. in distress.

    2. I.F.F codes employed by ships and aircraft will be in accordance with C.B. 04092/44. These are as follows:
    3. Code No. 1 (N N N N) - For normal use.

      Code No. 2 (N - N -) - Spare.

--Sheet 6 of 8--


      Code No. 3 (N N N _) - Spare.

      Code No. 4 (N N W W) - When shadowing or engaging enemy surface units.

      Code No. 5 (N - W -) - When over submerged U-boat.

      Code No. 6 (N N W -) - to facilitate rendezvous.

      Distress setting (very wide) - for aircraft or ships in distress.

  1. Operation of Naval Shore Radar.
  2. Mobile radar equipment will be landed and operated on the flanks of the beach-head to provide warning of surface and low flying airplanes. Operation of these equipments will be coordinated with radar stations operated by the Army and Air Force. Reports from this station will be passed to surface plots in ships over the shore radar reporting wave.

  3. Interference.
  4. Enemy RCM equipment is known to be located in the vicinity of the assault area. Radar operators should be instructed in the appearance of such interference on radar screens and in the method to be employed to minimize it.

  5. Tuning of Radar Equipment.
    1. Air warning radar equipments will operate in the following bands only:
      1. 190 - 195 mcs
      2. 198 - 207 mcs
      3. 211 - 255 mcs

    2. For receiving the British type 78 transmitters installed in the M.L. navigation leaders, SC radar receivers should be tuned to 214 mcs.

APPENDIX 9

 

  1. General.
  2. Equipment has been installed in certain vessels and craft, the object of which is to render the enemy radars in-effective. This will accomplish the following:

    1. Prevent the enemy from tracking the movements of the assault forces and conceal as long as possible their strength and composition.
    2. Attract the enemy's attention to areas outside the assault area.
    3. Prevent the use of radar for the control of coastal batteries.
    4. Attempt to deny enemy's effective control of guided missiles.

  3. Control of RCM.
  4. Control over RCM equipment in naval vessels to prevent unforeseen interference with communications will be exercised as follows:

    1. By Task Force and Assault Force Commanders while forces are at sea, before "H" hour.
    2. By the Air Officer Commanding the Allied Tactical Air Force or his representative, after "H" hour.
    3. Special signals for control of RCM are given in Table I.

  5. RCM silence will be maintained until the leading minesweepers are detected, or until "H" minus 7 when equipments will be turned on by units which are south of latitude 50 degs. 10 min. North. Other units will turn on their equipments when they cross this latitude. The time and limiting latitude at which RCM transmissions are to commence may be changed because of propagation conditions. Any such change will be promulgated by he Allied Naval Commander in Chief on "D" minus 1 day. Commanding Officers of ships equipped with RCM will ensure that transmissions will commence in accordance with such altered instructions. Any change will be transmitted in the form:
    ONCO 15. Time "H" minus ____. Latitude ____ North.
  6. Restrictions.
  7. To avoid interference with allied radar and VH/F communications, RCM transmissions are to be restricted as follows:

--Sheet 1 of 5--


    1. Types 658, 659 and 662 are to stop transmitting upon removal of restrictions on W.A. radar (types 79, 279, 281, SK, SC and SA).
    2. Type 91 is to transmit only within frequency bands 330-400 mc/s, 445, 495 mc/s and 540-590 mc/s. Transmissions may be made between 530/540 mc/s. If Radar transmission is detected within these limits and with pulse repetition rate over 1,000 per second definitely proving its enemy origin.
    3. Type TDY is to be operated on frequencies as follows:
      1. Aboard minesweepers on allocated frequencies as instructed by Admiralty Signal Establishment at installation: i.e. until H-2 or removal of restrictions on W.A. sets, whichever is sooner, between 550 and 570 mc/s, and afterwards between 365 and 375 mc/s.
      2. Aboard cruisers and above until H-2 or removal of restrictions on gunnery radar sets, whichever is the sooner, between 550 and 600 mc/s, and afterwards between 350 and 380 mc/s.

  1. Operation of RCM after the Assault.
  2. When there is reason to believe that the enemy is no longer using radar control on shore batteries, RCM transmissions may be stopped by order of the Naval Commander Western Task Force. Transmissions may be recommenced by order of the Naval Commander Western Task Force or by the Commanding Officer of Fire Support ships.

  3. Use of Window.
    1. Window projected by rockets and starshell will be used by certain bombarding ships and may be available also for some minesweepers to provide "Window" cover to protect bombardment vessels from enemy fire control radar.
      1. The Window Rockets have fixed fuses and when fired at a fixed vertical angle of 40 degrees burst at a range of 2,000 yards and an altitude of 2,000 feet.
      2. The limited quantity of material on hand requires that rocket Window be used only under conditions of very poor visibility when there is clear evidence that enemy fire is becoming accurate.

--Sheet 2 of 5--


      1. After the first rocket Window is fired, the time lag before the radar protection is complete amounts to approximately eight minutes for relative wind speeds of 8 knots. This time lag is proportionately reduced for greater relative wind speeds.
      2. Instructions on use of Window rockets are issued separately to ships concerned.

  1. Anti-Radar Balloons.
    1. It is intended to supply a limited number of MARL IV Reflector Balloons to be towed in the neighborhood of bombarding units
      1. To provide alternative and confusing points of aim for individual ships,
      2. To increase the number of targets so that individual ships cannot be distinguished.

    2.  
      1. Reflector balloons should be placed in a position approximately 500 yards nearer the enemy radar station and between 2 and 4 degrees to one side for bearing as seen fro the enemy radar (i.e. offset by a mean of 400 yards at 8,000 yards and 900 yards at 18,000 yards).
      2. Balloons should not be taken across at not more than 100 feet in order to avoid premature location of forces by enemy radar and should not be within 45 miles of the beaches at H-7 hours.

    3. In the event of electronic R.C.M. failing an un-neutralized enemy battery can be expected to do accurate radar spotting.
    4. The effect of the balloons should be to force the enemy to "brown" the area covered by the ships and balloons.

  2. Counter Guided Missile Jammers.
  3. Certain ships are equipped with transmitters designed to jam radio control of glider bombs. This equipment may be used as necessary, bearing in mind that while in operation this equipment will probably completely blanket all communication channels. Operators of this equipment should be supplied with a list of frequencies above 20 mcs. being used by our own forces as an aid in identifying intercepted signals. Jamming should not be applied to individual signals for periods exceeding 60 seconds, without monitoring to verify that the signal being jammed is in fact an enemy signal.

APPENDIX 11

SECURITY OF COMMUNICATIONS

  1. The enemy's radio intelligence service will be fully alert and the enemy will be quick to take advantage of any breaches of security. The best safeguard against loss of security is strict adherence to the following:
    1. Proper discipline on radio circuits.
    2. Proper procedure.
    3. Accurate tuning of transmitters.
    4. Use of proper call signs.
    5. Reduction of traffic to that absolutely essential.
    6. Proper use of codes and ciphers.

  2. Transmissions of bogus messages by the enemy must be expected and guarded against. This can be prevented by:
    1. Constant vigilance by operators with a view to detecting other stations using their own call signs.
    2. Answering calls promptly.
    3. Avoiding requests for instructions in plain language.
    4. Authentication. (See appendix 4.)

  3. Calibration of transmitters on operational frequencies must be done as soon as the frequencies are known in order to avoid a rush of tuning just prior to sailing.
  4. The scrambling device installed on radio telephones has very limited security. After "H" plus 12 the security of this device will be limited to the unequipped listener.

APPENDIX 12

RADIO AIDS TO NAVIGATION

  1. Certain types of equipment for use as navigational aids have been installed in some vessels and craft of the Western Task Force. Details of these equipments and their capabilities follow:
    1. QH(GEE) Equipment - This equipment will be used to obtain fixes while on passage to and in the Assault Area. In the Assault Area, the maximum errors of fixes will be plus or minus 500 yards in longitude and plus or minus 1000 yards in latitude. In mid-channel fixes will be more accurate.
    2. Radar Type 970 - This equipment is installed in certain motor launches assigned the Western task Force as navigational leaders. Forecasts of the appearance of beach areas on the P.P.I. screen of this type radar have been calculated and, by comparison with actual appearance on the screen, off-shore fixes and ranges can be obtained.

  2. The details of other navigational aids used by British forces is given in ONCO, Section XVI.

--Sheet 1 of 1--


APPENDIX 13

COMMUNICATIONS FOR CONVOYS AND ESCORTS

  1. Radio communication with and within convoys will generally be in accordance with A.F.O. S.2/44 and CAMSI 2.
  2. Escorts will use the following waves:
    1. Convoy R/T (2410 kcs.) - This channel is guarded by all escort vessels in the convoy if practicable. It is used for intercommunication within the convoy and with covering aircraft other than fighters. It is common to all convoys ad is likely to be congested so that its use must be strictly limited.
    2. Port wave (A.F.O. S.2/44) - The appropriate port wave is guarded by the senior officer and second senior officer of the escort. Transmission by ships should be restricted to enemy reports and other emergencies.
    3. Channel Ship-Shore Calling wave (2700 kcs.) - This circuit is available to all ships as required for passing traffic to shore stations.
    4. CN Broadcast (100 kcs.) - This broadcast is copied by all major war vessel escorts.

  4. When moving from the area of the Plymouth or Dover command port waves into that of Portsmouth, the senior officer of the escort should arrange for a guard to be kept on the former until arrival in the Assault Area.
  5. South of Latitude 49-40 North watch will be set on the Task Force Auxiliary wave of the Task Force to whose area the convoy is routed. This replaces the watch on the port wave.
  6. In homeward bound convoys, a guard on the Plymouth or Dover port waves will be set upon leaving the Assault Area.
  7. Convoy organization "C" (CAMSI 2) will be in effect for all convoys but it is to be amended as follows when between 0 deg. 30 min. East and 1 deg. 30 min. West:
    1. All ships which are able to do so will set an R/T listening watch on 2410 kcs. and in addition a watch on 500 kcs. for distress messages.
      1. From half an hour before sunset to half an hour before sunrise.
      2. When attacked.

--Sheet 1 of 3--


      1. When visibility is less than one mile.
      2. When so ordered by the Senior Officer of the Escort or the Convoy Commodore.

  1. Broadcasts are made in plain language and times mentioned are double summertime. Bearings and distances are calculated from the center of the convoy. The object of the R/T broadcast is to give warning of enemy air or "E" boat attack, warning of th approach of friendly aircraft, and orders for opening or ceasing fire.
  2. South of 49 deg. 40 min. ships will set watch on he appropriate Task Force air warning circuit. The senior officer of the escort will inform ships to which circuit to guard upon crossing this latitude.
  3. Stragglers will set watch at 1650 kcs. instead of 2410 kcs. to receive warnings from Niton.
  4. The authority sailing a convoy will carry out the normal procedure and will also inform the Allied Naval Commander in Chief of its sailing giving the following information:
    1. The number, code word, radio distinguishing group, composition, and destination of the convoy.
    2. If starting from a port in the United Kingdom, positions in the convoy cruising order.

    The Allied Naval Commander will then signal to the escorts and he authorities sailing joining sections:

    1. The positions in the cruising order to be occupied by joiners.
    2. The destination of the joiners.

  5. In the initial phases, convoys will be routed to the appropriate beach areas. On arrival the senior officer of the escort will get in touch by visual with the Captain Southbound Sailings in the Eastern assault Area or the Far Shore Shuttle Control in the Western Assault Area. If necessary these authorities can be called on he Task Force Auxiliary Wave by radio when FOBAA/FOWEST takes over, calls should be addressed to him.
  6. Convoys will be divided into sections proceeding to different beach areas as directed.
  7. Escorts will make use of direction finders and other equipment available to intercept enemy "E" boat and other transmissions. See CB 4002N series of publications.
  8. LST's and other landing craft making passage across channel will guard the following circuits in the group:

--Sheet 2 of 3--


    1. NITON Broadcast on 1650 kcs.
    2. ETF Landing Wave (660 kcs.) or WTF Voice (2716 kcs.)
    3. Task Force Auxiliary or Port Wave.
    4. Channel Ship-Shore Calling.

  1. Upon arrival in the Assault Area, craft will be routed to appropriate beach areas.
  2. Groups of landing craft will be designated by the following code words followed by numbers allocated to sailing authorities:
    1. Outward bound - STARLIGHT
    2. Homeward bound - BLUESKY

  3. Homeward bound groups will normally be routed to their own force collecting areas. On sighting the Port War Signal Station the senior officer of the group will flash his identity and hoist the International pendant indicating the number of his group in the BLUESKY series.
  4. Convoy code words and radio distinguishing groups are given in Appendix X to ON 13.

--Sheet 3 of 3--


APPENDIX 14

COMMUNICATIONS FOR MULBERRY, GOOSEBERRY, AND PLUTO
