    IpalmwRe .OLYMPIC, includin control in ease of exigencies of the actual amphibiousassault through the appropriate naval commander. The land campaign andrequirements therefor are primary in the OLYMPIC operation. Account ofthis will be taken in the preparation, coordination and execution of plans.(8) The Commander-in-Ghief. United States Pacific Fleet is charged with theresponsibility for the conduct of the naval and amphibious (subject to sub-paragraph c. (7) above) phase of the OLYMPIC operations and correlateshis plans with the Commander-in-Chief, United States Army Forces in thePadfic.(9) The Commanding General, Twentieth Air Force cooperates in the plans,preparations and execution of operation OLYMPIC and in the continuanceof thecampaign in JAPAN . At appropriate times, to be determined by theJoint Chiefs of Staff, the Twentieth Air Force coines under the direction ofthe appropriate commander for the support of operations directed above.

    2. ASSUMPTIONS.a. Hostile. (See Annex 2 a, G-2 Estimate of the HostileSituation in the Pacific Area (Under separate cover) .)

    (1) That the Japanese will continue the war to the utmost extent of their capa-bilities and will prepare to defend the main islands of JAPAN with everymeans available to them. That operations in this area will be opposed notonly by the available organized military forces of the Empire , but also by afanatically hostile population.(2) That approximately three (3) hostile divisions will be disposed in SouthernKYUSHU and an additional three (3) in Northern KYUSHU at initiationof the OLYMPIC operation.(3) That total hostile forces committed against KYUSHU operations will notexceed eight (8) to ten (10) divisions and that this level will be s@xdilyattained.(4) That approximately twenty-one (21) hostile divisions, including depot divi-sions, will be on HONSHU at initiation of that operation and that fourteen

    (14) of these divisions may be employed in the KANT0 PLAIN area.(5) That the enemy may withdraw his land-based air forces to the Asiatic Main-land for protection from our neutralizing attacks. That under such circum-

    (6)

    That the entire resources available to the Commander-in-Chief. United StatesArmy Forces in the Pacific and the Commander-in-Chief. United StatesPacific Fleet will be availab!e for the support of these operations.That there will be no effective redeployment of majo r ground combat unitsfrom EUROPE in time for commitment prior to early 1946.That entry of RUSSIA into the war against JAPAN at some stage of theoperations may be expected.That United States Forces will be established on the line BONINS-NorthernRYUKYUS at initiation of the operations.That at initiation of the operations, land-based air forces will have attainedoffensive air superiority over Southern KYUSHU. That strategic land andcarrier-based air forces will have effectively crippled the hostile aircraftand electronic8 industries and reduced capacity of rail lines in SouthernHONSHU, SHIKOKU and KYUSHU to an extent providing little capacitybeyond tactical needs.That at initiation of the operations the United States Pacific Fleet willdominate waters east of the main islands of JAPAN, and the EAST CHINASEA and a8 far north as Southern KYUSHIJ. That forward naval baseswill be functioning in the PHILIPPINES, RYUKYUS and MARIANAS.

    3: OPERATlONS.a. Concept. (See Chart, Annex 3. a., General Concept of Operations).Mis Plan of campaign visualizes attainment of the assigned objectives by two(2) successive operations, the first to advance our land-based air forces into SouthernKYUSHU in order to support ,the second, a knock-out blow to the enemys heart in the

    TOKYO area. The operations are continued and extended until such time as srganizedresistance in the Japanese Archipelago ceases.Concept of the OLYMPIC operation visualizes entry into Southern KYUSHU bymajo r joint overseas landing operations after intensive a ir preparation. Preparatory air

    against the Asiatic Mainland as necessary. Logistic facilities are established in the TOKYOWAN to support consolidation of central and northern JAPAN.It is estimated that the maximum air garrison will not exceed fifty (50) groups,which figure is subje@to revision as the situation develops.Occupati&; o f the KANT0 PLAIN is followed by such operations from theOLYMPld and CORONET areas as may be necessary to terminate organized resistance inthe Japanese Archipelago. .If required by the situation prior to CORONET,,intermediate operations are con-ducted to establish advance fighter elements in Southern SHIKOKU or Southeast HONSHUto cover our advance.In event forces allocated OLYMPIC operation are insufficient to accomplish *tasksassigned, build-up in OLYMPIC area from elements earmarked for CORONET is continuedat the rate of three (3) divisions per month beginning about (X plus 30) with supportingtroops a8 required by the situation. The CORONET operation is adjusted accordingly.In event forces allocated CORONET operation are insufficient to successfully per-form tasks assigned, build-up from the War Department Strategic Reserve is continued directto the objective area at a rate of four (4) divisions and appropriate supporting troops permonth beginning about (Y plus 90) to a strength required by the situation.The United States Pacific Fleet conducts the amphibious phases of the opera-tions, supports ground action after landing and covers the operation by naval and air actionagainst hostile supporting air, naval and land forces.The Twentieth Air Force, initially employed on strategic targets in coordinationwith long-range land-based and carrier-based air action, tactically supports as necessarythe amphibious and ground phases of the respective assaults.The Commanding General, CHINA Theater cooperates by conduct of diversionaryand containing operations within the limits of his capabilities.Should RUSSIA enter the war prior to completion of the CORONET assaultphase. diversions from forces herein allocated may be directed by the Joint Chiefs of Staff inorder to establish and maintain a sea route to Eastern SIBERIA. In this event, the operationsoutlined above are conducted with minimum alteration, such adjusttients being made in tim-ing a8 may be required to procure essential replacements for the forces committed.

The instructions of this Commander,wherever practicable, are transmitted to the appropriate land-baaed air echelon through an Army Air Controller who accorn-parries the Naval Air Commander designated.Similarly, after land-baaed air forces are established in an objec-tive area and responsibility for air operations passes to CIN-CAFPAC, control of carrier-based air elements operating in anobjective area is exercised by the Commanding General, Far EastAir Forces, wherever practicable through a Navy Air Controllerat the objective area. Amount of carrier-based air available foroperations in an objective area and the duration of such supportare established in the plan for the specific operation.Definition of objective areas, duration of amphihioua phases andamount of land-baaed air available for operation in objectiveareas, are established in the plaris for specific operations.
