(A)          ORGANIZATION OF THE JAPANESE FLEETS. October 30, 1941.



The following revision of Op-16-F-2, O.N.I. Serial #27-41 supersedes and replaces the former report on this subject.


The principal change consists of a further increase in the number of fleet commands. This has arisen from the regrouping of aircraft carriers and seaplane tenders into separate forces, and from the creation of special task forces in connection with the southward advance into Indo-China. The regrouping has resulted in a notable specialization within the various commands, as shown below.


Page 54


                    MAJOR FLEET COMMANDS

I. Combined Fleet

   1 First Fleet      (Battle Force)           3 Batdivs, 1 Crudiv,

                                                 2 Desrons

   2 Second Fleet     (Scouting Force)         4 Crudivs, 2 desrons,


   3 Third Fleet      (Blockade & Transport    Small craft.


   4. Fourth Fleet    (Mandate Defense Force)  1 Desron, 1 Subron and

                                                 many small units

   5. Fifth Fleet             ?                         ?

   6. Sixth Fleet     (Submarine Fleet)        6 Subrons

   7. Carrier Fleet   (Aircraft Carriers)      5 Cardivs

   8. Combined Air    (Seaplane tenders, etc.) 4 Airrons, & shore based

      Force                                       planes


II. Japanese Naval Forces (Staff Headquarters)  1 PG and 3 DD s

      in China.

   1. First China Exped.  (Central China)       Gunboats


   2. Second China        (South China)         1 CA, 1 CL and small

       Exped. Fleet.

   4. Southern Exped.     (Saigon)              1 CL, transports and

         Fleet.                                    mine craft.


[117] The Japanese Navy now includes more vessels in active service than ever before. More merchant ships have been taken over by the Navy, and the line between merchant ship and naval auxiliary grows fainter all the time. The base forces and guard divisions in the Mandated Islands have also greatly increased the strength of the Navy, which is on full-war-time footing.

[124]                    COMBINED AIR FORCE


                   Kanoya Naval Air Station, Hdqtrs.


Shore-based land planes and seaplanes. The organization provides for great mobility. Air units are ordered to work with other forces, and return to the Combined Air Force pool when their mission is fulfilled. The named Air Groups (e. g. the Takao Air Group) are not tied down to their stations, but are sent freely wherever they are needed. Furthermore, the various air squadrons and air groups frequently split into smaller units, and are scattered over wide areas.

Because of this extreme mobility, the picture is constantly changing. Accordingly, the following list makes no attempt to indicate all the temporary groupings into which the various units may be combined.

1. FOURTH FLEET, which may be termed the MANDATE FLEET, apparently administers, the Naval activities, afloat and ashore and also the Army Garrisons units in the Mandated Islands. While the forces afloat exercise administrative jurisdiction over the Mandate area, the Yokosuka Naval District is directly responsible for the supply of stores, material and provisions. Truk is the headquarters for supply and munitions and has been principle Fourth Fleet operating base.


2. Up to the present the entire Mandated Islands have been lightly garrisoned, the majority of the garrison units being Naval Defense Forces ("special Landing Forces" corresponding to our Marine Corps) but some Army troops are believed to be on SAIPAN, PALAO, PONAPE, TRUK and JALUIT. The total garrison force has been estimated at fifteen thousand. In addition, there are Civil Engineering Units engaged in development work on various islands. Working in conjunction with these are naval engineering units, naval ordnance specialists, navy yard units with civilian navy yard workers and technicians. The network of naval radio stations has been greatly expanded, meteorological stations and high frequency direction finders installed at strategic locations, aviation facilities increased both in scope and number, and shore-batteries emplaced on strategic islands of key Atolls.


3. It is apparent that a decision to expedite the fortification, expansion of facilities and militarization of the Mandated Islands, was made late in 1940, probably concurrently with the signing of the Tripartite Pact. The movement of naval auxiliaries, small and medium cargo, freight-passenger vessels (ex-merchant marine) to the Mandates began in December, 1940, and has increased in scope and number until some seventy odd vessels are engaged in this traffic, the average number present in the Mandate area at any one time being some forty odd vessels.


4. The function of supply of munitions, supplies, material and provisions to the Mandates is under the YOKOSUKA Naval District with a Headquarters for Civil Engineering, Munitions, Military Stores and Supplies for the Mandates centered at Truk, although this function is normally under the jurisdiction of Yokosuka as the Mandates are in the First (HQ-YOKOSUKA) Naval District.


5. The Commanders of the 3rd, 4th, 5th, and 6th Base Forces are subordinate commanders under Commander-in-Chief, 4th Fleet; they have a designated Flag-

ship and a Headquarters or Administrative Section, the latter remaining ashore at the home base regardless of the movements of the command or the Flagship. Each Base Force contains a DEFENSE FORCE, detachments of which are stationed on outlying islands of that general area. Four Ro Class submarines have been reported to be attached to the PALAO BASE FORCE.




6. Considerable air activity has been in evidence in the SAIPAN PALAO-PELELIU, TRUK, PONAPE and JALUIT-KWAJALEIN areas. Close cooperation has been noted between the Defense Forces and the Aircraft activities at their home bases. Foreign steamers nearing the SAIPAN area have been subject to aircraft observation and close scrutiny by Patrol planes, Bombers and fighters. Heavy land plane bombers and Patrol planes, undoubtedly ORANGE, have made reconnaissance flights over the Gilbert Islands (TARAWA; BUTARI-TARI, and BERU).


7. The distribution of material, personnel, and installations in the Mandated Islands is indicated in table "A". While this is admittedly incomplete and may be subject to inaccuracies, it represents the latest and best intelligence on this subject. In addition to those listed in Table A, there are a number of potential bases, principally in the lagoons of the naturally protected atolls, which may be used as emergency bases or may be earmarked for "priority two" development.


8. The latest information (up to 25 November 1941) indicates that the present distribution of the Air forces (believed to be a temporary strategical disposition other than a permanent assignment) in the Mandates is:

The exact composition of these Air Groups is unknown and the estimates of total plane strength in the Mandates vary widely: 62-268 planes.

These pages will be found reproduced as Items Nos. 2, 3, 4, and 5) EXHIBITS-ILLUSTRATIONS, Clausen Investigation. These illustrations will be found bound together following the printed exhibits of the Clausen investigation.)




1. Aviation facilities.-Two landing fields, each with a hangar capable of using twenty medium sized planes. Engineering Shop (camouflaged) situated between the two fields. Adjacent storehouses (galv. iron) camouflaged. Diesel fuel and gasoline storage in camouflaged, above-

ground tanks adjacent to air fields. Diesel power plant (June 1940). Eighty planes reported based here (November, 1940).


On beach opposite southern air field is Naval Air Station having small ramp and one hangar for seaplanes (June 1940). This may be an auxiliary as present indications point to naval air Base on IMIEJI (EMIDJ) Is.


2. Headquarters-Two story concrete building. Large building to SE of headquarters is Post Office and Telephone central. Flagstaff adjacent to Post Office is also used as signal tower. In town are many one story concrete stores. Good bituman and powdered coral roads.

3. Radio towers.-Two steel combination radio and lookout towers 400 feet high. Diesel engine power plant near southern tower (1940).


4. Shore Batteries-Bases and trunnions along the three quarter mile water-front street called the Marine Parade (1940) (guns not mounted in June, 1940 but are now). Also three 6" guns and a battery of four 4.7" field pieces. Barracks for regular garrison of 500 soldiers (1940) (probably enlarged now).


Mobile Batteries-Machine guns and AA guns mounted on Diesel-tractor towed trailers. 10 searchlights on pneumatic tired truck assemblies (1940).
