Part V. TYPE ORGANIZATIONS

5000.

The following chapters discuss the organizations of a combat information center for specific classes or types of ships. For uniformity the material will be considered in its relation to parts I through IV. Where details are discussed in earlier sections they will be referred to only in the manner (if any) in which they differ from the general details of the earlier sections. Definitions will conform to part I. Each type organization will be discussed under the following headings:
Introduction:
Basic functions of the command on the type of ship being considered:
Functions, duties, and responsibilities of CIC.
General functions with reference to parts II, III, and IV of RAD SIX.
Special duties and responsibilities in type of ship being considered, which are not covered by earlier sections.
Administrative organization of CIC, (Pending decision).
Diagram of CIC (and auxiliary CIC, where applicable) (Showing equipment, design, and stations of personnel involved).
Communications of CIC:
Diagram of S/P communications and other intraship communications (MCs, voice tubes, etc.)
Equipment used for intership radio communications.
Operational organization of CIC:
Diagram of battle bills and condition watches.
Detailed duties.

The watch bills are necessarily presented as a composite of the types and are furnished only as a guide.

Communication diagrams show circuit outlets, authorized for the CIC of the type.

5100. The CIC in an Amphibious Command Headquarters Ship (AGC).

      5101. The AGC type of ship has been designed for serving as the flagship of the amphibious force commander. An amphibious operation may involve hundreds of ships and landing craft of all types. The elements of a typical amphibious force are shown in the accompanying diagram (fig. 1).
      5110. Functions, duties, and responsibilities of CIC.

            5111. The combat information center in an AGC shall be organized to perform the general functions listed in parts II, III, and IV of this publication.

            5112. Essentially the duties and responsibilities of CIC in an AGC are similar to those of any other ship. However, all data must be evaluated and processed in terms of the whole force in addition to data in terms of the single ship because of the presence of a flag aboard. It frequently is the responsibility of CIC on an AGC to coordinate the functioning of other CICs in the force. Aboard an AGC, the personnel in joint operations room, flag plot, and the staff duty officer rely on CIC for much information.

      5120. Administrative organization of CIC. (Pending decision.)

      5130. Diagram of CIC (fig. 2).

      5140. Communications in CIC.

            5141. Diagram of sound power and other intraship communications (table 1). The purpose of the accompanying diagram is to show those circuits which, are commonly used by each individual, not the number available.

5142. Equipment used for intership radio communications. The allowance of radio equipment changes often, and the installation at times varies from the allowance. A specific list of radio equipment would therefore be misleading. The VHF channels available will indicate in a general manner the extent and type of radio equipment provided. Remote radio phone units and speaker amplifiers provide CIC with a flexible means for transmitting and receiving on multitudinous channels.

      Equipment	Frequency	Examples of use
      2 remote control transmitters and speakers.	VHF	Maneuvering and emergency warning.
      4 transmitters and receivers.	VHF	Fighter net, inter-CIC and support aircraft direction.
      4 10-channel transmitters with 2 10-channel receivers.	VHF	Aircraft control force (group) CIC circuit.
      2 radio telephone units (R, P, U.) (transmit and receive).	VHF, HF	Fighter net, CIC circuit and local air warning.

COMINCH P-013

2. The evaluator's station should have a selector switch to the principal sound power circuits with call-up buttons to local air (joint ops), staff watch officer's shelter, pilot house, intelligence office, joint operations control, and war command room.
2. CIC officer:

   1. The CIC officer should be an experienced officer, qualified in all phases of CIC work. He is responsible for the training and administration of the combat information center. He should be qualified to take over the evaluator's position at general quarters when that officer is required elsewhere.

   2. The CIC officer's station should have a selector switch to the same sound power circuits as the evaluator. In addition, his station should have a voice radio selector switch connected with the principal transceivers and transmitters. The MC circuits and ship's service telephone should be convenient for his use.

   3. The CIC officer normally should not stand condition watches but will be on call at any time.

3. Fighter director officer:

   1. The fighter director will be directed by the evaluator or CIC officer to take over the responsibility for interception of a specific raid threatening our forces. He should alternate with the CIC officer during extended general quarters (Condition I A) and act as evaluator during the absence of both the CIC officer and the evaluator.

   2. The fighter director station should have a voice distribution system utilizing all VHF channels used for aircraft control and inter-CIC reporting.

   3. The fighter director normally should not stand condition watches but will be on call at any time in event enemy aircraft threaten our forces.

4. Assistant fighter director officer:

   1. The assistant fighter director should be an officer qualified to conduct the interception of enemy aircraft. He should supervise the intercept plot and handle visual fighter direction if the necessity arises.

5. Summary plotters and the radar control officer:

   1. The summary plotters will man the vertical plotting board. The men will plot radar, radio, and lookout information on the back of the transparent plot, and the radar control officer may filter this information when necessary. The radar control officer should see that all air information is available and assist the evaluator.

   2. Sound-powered radar circuits are available to the summary plotters. The radar control officer should have a radio phone selector switch and the necessary sound powered outlets available.

6. Geographic plotters:

   1. The geographic plot officer is a CIC watch officer who supervises the plotting on the DRT and the surface plot as well as the solution of surface tactical problems. He should see

COMINCH P-013

that all information is readily available and assist the evaluator in every way possible. An enlisted man assists him.
7. Gunnery liaison officer:

   1. The gunnery liaison officer should be an officer from the gunnery department who should stand watch in CIC at general quarters. He should be responsible for passing to gunnery control all information required. The lookout talker may assist the gunnery liaison officer.

   2. The gunnery liaison officer's station should include sound-powered telephone selector switch with radar, gunnery, and command circuits.

8. Surface plotter:

   1. The surface plotter may be an enlisted man who keeps the surface plot up-to-date under the direction of the geographic plot officer.

9. Intercept plotters and DR plotters:

   1. The intercept plotters should be enlisted men who will plot the track of enemy raids and DR plotters should dead reckon friendly fighters sent to intercept. The are under the supervision of the assistant fighter director.

10. Status board keepers:

    1. The status board keepers will be enlisted men who will handle the surface and air status boards respectively. The geographic plot officer should supervise recording on the surface status boards and the assistant fighter director should supervise the keeping of the air status boards.

    2. The surface status board keeper should have the low angle search radar circuits available. The air status board keeper should have an outlet from the VHF equipment used for the fighter net.

11. Lookout talker:

    1. The lookout talker should man the JL (or JC) sound power circuit and relay lookout and gunnery reports to CIC. He may plot air and surface contacts on the summary plot.

12. Radar operators:

    1. The two radar operators are desirable at each radar during general quarters permitting continuous operation with one man on the set for 30 minutes and then resting 30 minutes while the other takes over. During condition watches the radar operators should rotate duty with the enlisted talkers and plotters.
5153. During condition II and III watches there should be two officers stationed in the CIC. The CIC watch officer in charge should act as evaluator and coordinate the functions of the CIC. The assistant CIC watch officer will aid him in all respects, act as radar control officer when necessary, supervise plotting, and provide the solution of tactical problems.

5160. Joint operations room.
      A thorough knowledge of facilities and operation of the joint operations room is necessary for CIC personnel, if they are to be of maximum value.

      5161. This room is usually located on the main deck, amidships, forward of the ship's wardroom and just aft of the CIC. Here the staff officers of the Army (Marines), Navy and air forces of either service coordinate the employment.

COMINCH P-013

in detail of the forces participating and maintain and evaluate the complete picture of the battle situation.
5200. The CIC in a Relief Headquarters Command Ship (RAGC).

      5201. A RAGC is a vessel designed for serving as the relief flagship of the amphibious force commander. It will usually be an APA with modifications to accommodate a flag.
      5210. Functions, duties and responsibilities of CIC.

            5211. The general functions of CIC are the same as those listed in parts II, III, and IV of this publication.

            5212. The duties and responsibilities of CIC on a RAGC are similar to those of any other ship. When a flag is aboard, the work in CIC should be closely coordinated with the work of the staff which will depend upon CIC for much information.

5300. The CIC in an Attack Transport, Attack Cargo Ship and Destroyer Transport (APA, AKA, APD).

      5301. These vessels are designed as troop transports and cargo ships to be used during amphibious operations.
      5310. Functions, duties, and responsibilities of CIC.

            5311. The combat information centers on an APA, AKA, or APD should be organized to perform the functions listed in parts II, III, and IV of this publication.

            5312. Special duties and responsibilities:

                  1. Essentially the duties and responsibilities of CIC on these vessels are similar to those of any other type of ship. If the vessel acts as a group or division flagship the staff will rely on CIC for much information, and the work in CIC should be closely coordinated with that of the staff.

                  2. Boat wave tracking:
                     The function of boat wave tracking is performed by these types of vessels. In an amphibious operation the waves of assault boats must be carefully tracked by the parent ship and all interested stations kept informed of their progress toward the beach. It is possible to obtain from a good plot:

                     1. Course of boats to the beach or line of departure; whether they will reach the correct location.

                     2. Speed of waves; whether they will arrive at destination on time.

                     3. Position of marker, control, and support vessels.

5400. The CIC on a Battleship and Cruiser (BB, CB, CA, CL).

      5401. The functions of battleships and cruisers are essentially similar. Their main batteries of heavy, long-range guns are their chief reasons for being. These types of ships will be used mainly in surface actions and bombardments. They have also proved useful as an antiaircraft screen for carrier units.
      5410. Functions, duties, and responsibilities of CIC. The CIC is an agency for the collections of combat and tactical information by every possible means. Collected information is plotted, recorded, kept on file to facilitate its evaluation and dissemination to interested stations. Parts II, III, and IV of this publication deal with these general functions of CIC in detail.

            5412. Special duties and responsibilities:
                  The following functions will be performed by CIC. The order of importance is dependent upon the tactical situation.

                  1. Air search and warning.

                  2. Surface search and warning.

                  3. Recognition and identification.

                  4. Target indication.

                  5. Tracking.

                  6. Plotting.

                  7. Navigation.

                  8. Control of aircraft.

      5420. Administrative organization of CIC. (Pending decision.)

      5430. Diagram of CIC and auxiliary CIC, charthouse and flag plot, (figs. 4, 5, 6 and 7).

      5440. Communications in CIC. The sound power phones are CIC's primary system of interior communication. Outlets for a large number of circuits have been placed in CIC. To give flexibility to this system, many of the circuits have outlets through one of two types of switches--the selector switch or a panel of toggle switches. The advantage of each is also its disadvantage. With a panel of toggle switches, circuits can be crossed. This is sometimes desirable. It leads, however, to unintentional crossing, which may seriously impede communications. Selector switches permit being on only one circuit at a time. The single, double, or quadruple sound-powered jack-box outlets are also installed in CIC. Many circuits have outlets in CIC which are seldom used. These have been installed for the unusual situations. CIC's today have most of the sound-powered outlets in CIC wired through panel of 10 or 20 toggle switches.This means that a majority of the circuits leading to CIC are available to a large number of the personnel in CIC. Operationally this is misleading, because with a few exceptions each person in CIC has only one or a very limited number of circuits which he uses. The purposes of the accompanying diagram are not to show circuits which are AVAILABLE to each person but circuits which are COMMONLY USED by each individual.

COMINCH P-013

3. Know thoroughly the technique of DR as prescribed in the Air Plotting Manual. (RADFOUR)
6. Geographic plotter:

   1. Maintain a continuous plot on the DRT of own and enemy ships to determine their course and speed and any changes therein.

   2. Check scale setting of DRT frequently.

   3. Supply bearings and ranges course and speed for initial rangekeeper solution to gunnery liaison officer if requested.

    It is often desirable that he be an officer. He will be the surface plotter if a surface plot display is being kept on the plotting board he is manning, (i.e. all surface and air units, friendly and enemy). He should:

    1. Keep a continuous track of all surface contacts (or all surface and air contacts), to keep the cognizant personnel in CIC informed of the identity of any surface radar contact (if summary plotter, any surface or air contact) in question.

    2. Aid the gunnery liaison officers in preventing the fire of own ship from endangering friendly ships.

    3. Maintain a relative plot of own disposition.

11. Assistant surface (or summary) plotter:

    1. Assists the surface (or summary) plotter in the execution of his duties as outlined above.

12. Recorders--geographic: surface (or summary). The geographic and surface (or summary) recorders should keep an accurate record of radar ranges and bearings. use of VG (projection PPI) with tracking paper may obviate the necessity of having recorders. If proper plotting procedure is used, the tracing paper on the VG will preserve the record. This together with equipment for photographing the PPI will aid in keeping a record of the action.

    Tracing paper on the DRT may give sufficient information to reconstruct an action; however, the geographic plotter is often in need of a reference if he misses a range or bearing. If the raid time, bearing and radar range data is presented conveniently for all concerned on the surface status board, it will not be necessary to have a surface recorder as such. When this, due to the physical limitations of CIC's, is not applicable, it is necessary to provide a recorder for either the geographic plotter or both geographic plotter and surface (or summary) plotter.

13. Surface status board keeper. The surface status board keeper should be under the supervision of either the surface (summary) plot officer or the geographic plot officer. He should:

    1. Maintain an up-to-date record of the tactical data on the board.

    2. Record data on surface raids, if board is designed to include such data.

14. Air status board keeper. The air status board keeper should be under the supervision of the fighter director officer. He should:

    1. Maintain an up-to-date record of all intercept information.

    2. Keep posted such information as condition of weather, clouds, states of sea, time of sun and moon rise and set, current, drift, force of wind, etc.

    3. Record information on physical condition of fighter planes, ranges and bearings of enemy planes and force, losses, status of own carriers and patrols.

15. M.B. (main battery) gunnery liaison officer. M.B. gunnery liaison officer shall by observation of the surface search radars, the geographic plot, the VF, the surface or summary plot:

    1. Keep the evaluator and gun control stations informed of the surface gunnery situation.

    2. Analyze all contacts by checking IFF indications, lookouts reports, and the known location of own ships and land masses.

    3. Inform the AA liaison officer of any air targets appearing on surface radar scope.

COMINCH P-013

4. Check CIC's computation of courses and speeds of targets being tracked against M.B. plot computer-solution.

5. Coach directors on target as ordered.

6. Check director train and range indicators to insure they are on designated targets.

7. Warn evaluator and gun control stations when own ships are in danger of own firing.

8. During shore bombardment (indirect fire), give advanced range, bearing, and elevation of the target.
16. Antiaircraft (secondary battery) gunnery liaison officer.

    1. Keep the evaluator and air defense officer informed of the developments in the air situation.

    2. Make every effort to determine the character of contacts by checking for IFF, approach bearings, altitudes, course, speed, identification by lookouts, and location of own air patrols.

    3. Coach AA fire control directors on to designated targets employing target designators or the appropriate telephone circuits.

    4. Insure that directors are on designated targets by checking target range and bearing indicators located in CIC.

    5. During low visibility torpedo attacks insure that AA guns do not fire on bearings which endanger other ships of the screen.

17. Surface and air search operators:

    1. Maintain an alert search on the prescribed range scale, with the antenna rotating at the prescribed rate.

    2. Report all contacts, amplifying initial reports as additional information becomes available.

    3. Report all unusual or doubtful indications, and be able to recognize double echoes, side lobes, ionized clouds, second trip echoes, wake signals, interference jamming, window, land echoes, aircraft, and surface craft.

    4. Check all contacts for IFF, when ordered, and identify the code.

    5. Know disposition of ships in company.

18. Communications officer:

    1. Supervise the watch on all radio circuits and inform the evaluator of all pertinent incoming messages.

    2. Encodes and transmits messages as directed by evaluator (e.g., contact and amplifying reports).

    3. Decodes messages received, notifying personnel concerned.

    4. Be familiar with and have access to standard tactical instructions and the current operations and communications plans.

19. Radio recorders:

5752. Detailed duties.

      1. Evaluator (executive officer) should:

         1. Exercise general supervision over the collection of all combat and tactical information by CIC.

         2. Evaluate this information.

         3. Disseminate the evaluated information.

         4. Recommend courses of action to the commanding officer.

         5. Assist in the execution of chosen courses of action.

         6. Execute any specific control functions which command may delegate to CIC, such as target designation, torpedo firing control, and the monitoring of voice circuits.

         7. Maintain an hourly plot of ship's position on the strategic chart.

      2. CIC Officer (division officer) should:

         1. Execute direct supervision over the collection of all information by CIC and its presentation to the evaluator.

         2. Assist in evaluation.

         3. Prepare contact and all amplifying contacts.

         4. Use CIC aids, such as the maneuvering board and MK 7 angle solver in the solution of tactical problems.

         5. Be prepared to serve as evaluator.

         6. Be prepared to serve as fighter direction officer should an emergency warrant detailing limited fighter direction to the ship.

      3. Geographic plotter, assistant geographic plotter, surface recorder, should:

         1. Track unidentified and designated targets on the DRT.

         2. Note on the plot all amplifying data, such as identification, course, speed, number of targets, in group, wind direction, firing of and track of torpedoes, and opening of gunfire.

         3. Maintain an orderly record of time, range, and bearing of all plots.

         4. Be able to track 2 targets simultaneously, plotting each once a minute.

         5. Be able to track 2 targets simultaneously, plotting each 1 a minute, while at the same time maintaining an approximate multiple plot on at least 10 other targets.

         Procedure:

         1. Destroyer escort and frigate IFF should be considered non-directional. Apparent IFF bearings should not be used in checking identification of targets. With two targets at the same range, analysis should be made by the CIC officer before noting, friendly indication for either target. The plotters should not make this deduction themselves.

         2. In tracking targets at long range where the radar pip may fade, the radar operator should give the time mark. Where radar conditions permit, the recorder should give the time mark, preferably at regular intervals.

         3. To avoid confusion in sonar target tracking, only the time mark, center bearing, and range should be furnished the plotting team. Such information should be furnished by the sonar-hut over sound-powered phones. Other sonar

COMINCH P-013

information required by the evaluator should be collected over other phone circuits. Use of the 21 MC should be avoided.
4. Whenever possible standard scale settings of 2,000 yards per inch should be used on the DRT for plotting surface targets, and 200 or 500 yards per inch for sonar targets.
4. Air plotter and assistant air plotter should:

   1. Maintain an air plot of all air radar contacts for identification and defensive gunnery purposes. This primary function should not be sacrificed for the tracking of specific targets.

   2. Track only those air targets designated by the evaluator.

   3. Dead reckon friendly planes.

   4. Note all possible amplifying data on unidentified and enemy targets, such as course, speed, altitude, size, and number.

   5. Be able to maintain a plot on at least 10 different air targets.

   6. Keep air information on data board.

   Procedure:

   1. Apparent IFF bearings should not be used in checking identification of air targets. With two targets at the same range, the air plotters should make a careful analysis before noting which is showing IFF.

5. Surface plotter should:

   1. Maintain a plot of the relative location and identity of all surface targets within radar or visual range. When disposition or size of force makes this impossible with all targets, emphasis should be centered on the following:

      1. New or enemy targets.

      2. The guide.

      3. Adjacent ships.

      4. Major radar land marks.

      5. Screening ships.

   3. Maintain the relative movement line of each target, paying particular attention to adjacent ships.

   4. Keep posted on the data board the disposition, formation, course, speed, and axis, patrol speed, and details of zigzag plans.

   Procedure:

   1. Man JA circuit to receive lookout reports.

   2. Obtain radar information by reading surface search radar scope directly, without interfering with the operation.

   3. Label identified targets with the TBS calls, or with raid designations as directed by the CIC officer.

6. Surface search radar operator should:

   1. Search for new targets, using normal operating procedure.

   2. Maintain this search effectively at all times, even when providing data on targets.

COMINCH P-013

3. Reports new targets immediately to evaluator and obtains his acknowledgment.

4. Check unidentified targets for IFF, first requesting permission from the evaluator, and report results to surface plot.

5. Furnish ranges and bearings to surface plot as requested.

6. Furnish ranges and bearings of guide to the OOD or evaluator upon request to assist in station keeping.

7. Make immediate and forceful reports to the evaluator of any target closing the ship within one thousand yards and obtain his acknowledgment.

8. Check the alignment of azimuth on scope each half hour against ship's head by magnetic compass if using SL radar.

9. Report any casualty or erratic performance of the radar to the evaluator.
7. Air search radar and assistant operator should:

   1. Search for air targets, using normal operating procedure.

   2. Maintain this search effectively at all times, even when providing data on targets.

   3. Report new targets to evaluator immediately and obtain his acknowledgment. Indicate as soon as possible the size of contact, altitude, and number of aircraft in group.

   4. Check unidentified targets for IFF< first requesting permission from the evvaluator, and report results to air plot.

   5. Furnish ranges and bearings to air plot to assist in tracking.

   4. Report any circuit failure to the evaluator.

   5. Inform the CIC officer when unable to keep up with traffic volume.

   6. Assist in decoding and encoding voice messages as traffic permits.

9. JA talker should:

   1. Serve as the evaluator's talker, unless the evaluator himself wears the phones, in which case the talker is not necessary.

   2. Report to the evaluator all transmission on this circuit.

   3. Report routine information to the bridge when directed by the evaluator.
5753. The following stations should be manned in CIC during war cruising conditions:
