There are also two light bomber squadrons equipped with 1126 Invaders, two transport, one reconnaissance0 and six artillery and observam ion and liaison squadrons.

The French Naval Air Ana in Indochina has a current strength of 25 aircraft all shore based. The CVL Arrcalanches left Indochina for France on 18 May for overhaul and is expected to return in the latter part of August.

Sixteen airfields meet the standards necessary to operate combat .aircraft. Of these? twelve have permanent surfaced rucmays., five of which have a runway length of over 5,000 feet and are capable of sustaining medium bomber/,jet fighter aircraft operations. The remaining airfields have over 4000 foot runways and are suitable for operation of light bomber/piston fig'ntor type aircraft and limited jet fighter operations, The most important airfield complex is located in the critical Tonkin Delta area. Here are based approximately 60,E of all the FAEEO combat aircraft and it is from these airfields that most of the close support and supply missions have been flown. Two air- fields Do Son and Kim An., have recently been put into commission by the French to relieve the eonjected situation existing in this vital area. The two Hanoi airfields and the one airfield at Haiphong have been overcrowded with aaires,aft with no adequate space for dieperual of aircraft, since the airfields are surrounded by rice paddies. The French-Vietnamese Forces possess no adequate radar or early warning systems capable of giving quick exarnfng to Army, Navy and Air installations in the Tonkin area, There isy at present., one radar warning site located at Cat 131 airfield (Haiphong), providing less than five minutes warning. Another of slightly better range is reported en- route from France. As a result of the movement of some transport and liaison type aircraft to Do Son and the use of Kien An and the three remaining delta airfields for cothat operations, this situation should be considerably ire= proved? All airfields in t:-is area are 'tdthin range of possible air attack #r Chinese Communist airfields in the bordering areas of Yunnan. and Ewangei Provinces and from Hainan' Island., If the Tonkin.

Indochina and is the hose base of the FAEEO. of the eight auxiliary seaplane stations available to the French i?aval Air Arm,, Cat Lai Seaplane station, 6 miles East of Saigon and Cam Ranh Flay near Phan hang are the only suitable seaplane landing areas, Combat .hffective[mss The capabilities of the FAS,EO are excellent in operations of a ',actical ground support nature.; which constitute their present basic mission. French pilots are presently well-qualified to perform tactical support and gunnery, During the past six months,, vital enemy supplies from Communist Chinas key points along the supply routes,, and other key targets have been effectively attacked, Through attacks against selected key targets, the movement of supplies is made as costly to the Viet t4inh as possible, The FAEEO are also efficient in conducting paratroop operations and supply by airdrop. Transport activities, photo .and visual reconnaissance, observa- tion and liaison are successfully carried out. Important French/Vietnamese outpost garrisons west and north of Hanoi, because of their isolation and poor lines of cansunication,, are supplied almost entirely by airdrops, Most of the sutposts have cleared "drop Zones" in the vicinity, and a few have short airstrips capable of handling liaison aircraft. The use of paratroops as a tatictical maneuver has proven highly successful in the type of war being fought in Indochina? The FAEEO would be relatively ineffective in air defense operations because of the lack of modern air interceptor air- craft, radar defenses and early warning; and fighter direction equipment. program in fighter combat tactics? air to air gunnery and air interception techniques. Completion of Do Son and Kien An airfields 'has increased the FMEO capability by providing additional operational bases and thereby greatly relieving the conjosted facilities and providing more dispersement of aircraft in Tonkin. Shortage of personnel imposed by troop strength limitations precludes the full utilization of aircraft currently available in Indochina. The FAEEO is understrangth in pilots, having 332 pilots for over 400 aircraft. Supply and maintenance staffs are short in aircraft technicians. The combat effectiveness of the shore-based French Naval Air Arm is goods within the limits of aircraft and facilities available, in per- forming its mission of patrol, reconnaissance,, destruction of enemy shipping and support of ground operations, b. What are the present French-Indochinese capabilities to: (1)rlspand their area of control and inflict heavy losses on the Viet Minh. assuming the present nature and degree of Chinese Communist assistance to the Viet Minh; (2) Hold presently occupied territory in Indochina against the Viet Minh operating with the present nature and degree of Chinese Communist assistance. There has been no air opposition to the FAEEO or the French Naval Air An in operati ns against the Vitt Minh. There is no evidence of an operational. Viet Minh air force. although some unconfirmed reports have been raceived indicating that Viet Minh personnel are undergoing aviation train- ing in the Sino-Tonkin border area under the Chinese Communists. The Viet Approved For Release 2000(0829: CIARDP79MlO12P-01000040007R y.' ,} ILiarh have received no known air assistance in the form of manpower or material from. the Chinese Communists, It is possible,, however,, that there may be a few air advisors among the several thousand advisors already with the Viet 14inh forces, If the Viet 114inh forces are to have air support during the period of this estimate, or the Chinese Corsriuniata should invade Indochina with ground units and desire such support, t:is would have to be provided by the CCAF, using regular units or "volunteers," Without oppositions the FAFEO, within its present area of, operations, is able to carry out effectively its current mission of tactical air support, subject only to limitations of personnel and equipment, However, the FAEEO is incapable of significantly expanding its air operations, (3) Resist attacks by the Viet Mirth operating with substantially increased Chinese Communist assistance? (4) Resist attacks by combined Viet Minh-Chinese.Conmunist Combat forces? Since the Viet Minh has no known air force in being and no immediate prospect of developing such a force prior to mid-r-1953, any air resistance to the FAEEO would presumable arise through the commitment of elements of the Chinese Communist Air Force to support of the Viet Minh forces? It is currently estimated that the Chinese Cwmaunist Air Force has available to it, approximately 2000 combat aifferaft of various types, Included in the combat figure are approximately 1300 jet type fighter aircraft, Of this total, approximately 800 aircraft (including 450 jets) are believed to be based in China proper, primarily in the Peiping,, Shanghai, and Canton areas, The nearest known units to Indochina are two air regiments, totaling 'i;, MIC?2.5 fighter aircraft, located at Canton. In south China, Approved For Release 2000(0829 CIA ROPAR01012A001000040007R therm are 18 airfields capable of supporting combat aircraft within 315 Approved For Release 2000N029: CIA RDPAR01012A0010000400078 + ` ' ~~ f H 1 F~~ nautical miles (the combat radius of the HIG-15 with two 70-gallong wing tanks) of the Tonkin Delta air installations. Five of these airfields have surfaced runways of 6000 feet or more and are suitable for sustained medium bomber/jet fighter operatima. The remaining ten airfields have surfaced run- ways between 4000-6000 feet in length and-can support sustained operations of light bomber/piston type fighter aircraft and limited jet fighter operations. Recent information indicates that Nanning airfield in southern China is absad- c:ned and that the Chinese Communists have not performed any construction work on this facility. Although the condition of the runway probably would allow aircraft to land and take-off, the air facilities are not suitable for any sustained operations. In event that the Chinese Communists were to attempt an air attack on Indochina, an operational base in the Nanning area would be essential. Lack of any activity at this airfield also indicates that there probably has been no major build-up of airfields near the Indochina border. The only evidence of construction in the area is that of a four-lane road being built from the town toward the airfield. The completion of this additional method of logistical support to the airfield may mean that the Chinese Communists have future plans for the rehabilitation of this airfield. It is believed,, moreover, that all Chinese Communist airfields in South China could be repaired within a short period of time. The commitment of a Chinese Communist force of ammparable size and composition to that now committed by the FA11C would not be decisive, but would materially reduce the freedom of movement now enjoyed by the FAEM, Loss of freedom of the air w ould force the FASOD to change materially its combat and supply tactics. Tactical support and bombing would be similarly affected since a large percentage of available aircraft would have to be employed in air 6 a irl Approved For Release 2000N029 yCIAROPAR01012A001000040007R intercept and combat patrol missions, The addition of a Chinese Communist air force to Viet Minh forces comparable in size to the French Air Forces, but including MIG-15 jet fighters would result in loss of air superiority to the French,, at least in the Tonkin Delta area, The FAEZO now possesses no aircraft capable of effectively intercepting jet type aircraft. It the Viet Minh/ Chinese Conmmnist ground forces commit MIG-l5?e,,.they will undoubtedly do so by a surprise concentrated air attack on the Army.. Navy and Air :installations in the Tonkin Delta area, The French-Vietnamese Forces do not possess an adequate air warning system to give quick warning of such an attacks and the effect would be to neutralize the French Air Forces in Tonkin and at least partially destroy the vital installations in that area? B. What is the current nature and level of Chinese CoLtmunist assts- tance to the Viet Minh? There is no known Chinese Communist air technical and materiel assistance being, provided to the Viet Minh at the present, C. What is the current nature and level of French sumort to the Associated States of Indochina? The Associated States of Indochina have no Air Force in beings although a small beginning has been made in training native pilots, On 1 April 1952, a Vietnamese Flying School was createdt, equipped with 30 .liaison type aircraft, and provided with a ;:raining staff of four French Air Force Officers and 22 non-commissioned officers? Graduates will be used in artillery spotting units, The initial class of 15 Vietnamese cadets is undergoing a 6 month course and a second class of 30 Vietnamese cadets is expected to begin training in October 1952 In view of the difficulties in organizing, equipping and t raining a native air fbree, and the preoccupation ct the French Air Forces in their present combat operations in Indochina, it is unlikely that an effective Vietnamese Air Force will be created within the period of this estimate. D. What is the current nature and level of US suooort to the French and Indochinese? Most of the present capability of the FAEEO is due to the MDAP assistance received during the past two years. Present MDAP policy provides for the replacement of aircraft and spare parts as needed to maintain the level now reached by the FAEEO and to supply all the ammunition and POL needed for combat operations as required. The lack of an air defense capability by the FAEEO has been i constant weakness that MDAP assistance has not alleviated? The French have repeatedly requested from the US jet aircraft for air defense in Indochina. These requests have been refused mainly because of their lack of air facilities to operate such aircraft, aid insufficient maintenance and fuel storage facilities for sustained jet operations. Recent developments and improvements along these lines in the 'Tonkin delta area, including opening two new airfields, have changed the complexion of this question in recent weeks. On 30 April 1952,, a recommendation for reconsideration of the question of jet aircraft to Indochina through MDAP was proposed by Air Force MDAP officialsa The proposal forwarded favors giving a squadron of F-86 to the FAEEO by realloting remaining FY 1952 funds. It is felt by this group that attacks by the CCAF, especially jet, could knock out a large part of the MDAP air effort already made in Indochina, If this threat is to be met by the French, an aircraft capable of forcing ccenbat on the 14IG-15 is ~-' " Approved For Release 2000N829 CIAROP]91UI1o12P-oioooodooo]8 A %WO for purchase, with delivery beginning in July 1953, If the FAFLO should acquire jets from the US, along with an early warning radar net also under consideration, the critical air defense weakness of the FAEEO now existing could, in time, be substantially alleviated, II, FACTORS AFFECTING FUTURr Dli4IAPA`ENT;IN ItIDOCHINA A. French-Indochinese Capabilities and ,probable courses of action. 1. How will French and Indochinese will and intention to resist be affected by the following: a. Political, economic, and military developments in Western Europe, and within metropolitan France and the French Union? Any political, economic, or military development within metropolitan France, other Western European countries, or the non=Indochinese parts of the French Union would probably have a favorable psychological impact upon French and Indochinese will and intention to resist if such development rem nulted in a continuation of sufficient outside support to contain the Communist threat to Indochina. In addition_, any development in these areas which indicated a genuine French intention to strengthen native institutions would tend to strengthen the Indochinese will and intention to resist Communist pressures, However, any developments in these areas which indica. ted a continuation of or a reversion tol, traditional French colonial policies and attitudes would meet with a strongly adverse reaction among the highly sensitive Indochinese peoples and would correspondingly deter their will and intention to resist Communist pressures, Any development in Metropolitan France, other Western European countries, or the French Union,, which indicated that Indochina would not receive outside support at least sufficient to contain the Communist threat would probably have a seriously Approved For Release 2000N829 CIA ROPIOR01012A001000040007R adverse. affect upon the wi.11 and ,i:h r;ti ril o resist of both the French and Indochinese? ba Political and economic trends within Vietnam,- Laos, and Cambodia;, including attitudes toward French imperial control and toward the Chinese Communists? (To what extent are the Chinese Communists regarded as conquerors and to what extent as liberators from white control)? Within Vietnam (and? to a lesser extent, within the less advanced stater- of Laos and Cambodia) there is a gsdual trend toward increased re- cognition of the Communist threat and toward increasing native participation in the French led resistance movement, However, despite substantial changes in traditional French colonial policies in the direction of sponsorship of native autonomy continuing suspicion of French policies and motives will remain,- during the period of this estimate, as a deterrent to unqualified Indochinese support for their own French sponsored governments and for the French-led military struggle against the Communist-led Viet Minh forces, It is estimated that identifiable direct Chinese Communist participation in combat against the French-Vietnamese forces would result in an acceleration of the present gradual increase in Indochinese support for the anti- Communist struggle. In view of the paucity of reliable intelligence, this estimate is based largely on the considered Judgment that, in view of the traditional Indochinese hostility toward Chinese invaders and in view of the increasing identification of the Chinese Communists in the minds of politically conscious Indochinese with aggressive international Communism, the threat posed by Como:*anist China will be regarded as over-riding the continuing opposition to French colonialism? e. Possible tripartite warnings to the CC to keep their hoops out of Indochina? The issuance of Approved For Release 2000N029: CIA ROPIOR01012A0010000400078 being effective in keeping Chinese Communist troops out of Indochina would increase French and Indochinese wall and intention to resist the Viet Minh forces? provided that US material support of the Frene~-Vietnamese forces continued at such a level that eventual victory over the Viet Minh did not appear hopeless* da Changes in the level of 'S economic and military assistance and in the nature of the VS commitment for the defense of Indochina? (See aA b and c above)? is, A cease-fire in Korea? A cease-fire in Korea., without effective Western action to deter Chinese romnunist military action against Indochina and/or without assurance of continued substantial US material support, would encourage defeatism among the French and Vietnamese and might lead them to seek a negotiated settlement with the Viet Minh forces, f.. An expansion of the Korean war? An expansion of the Korean war would probably have little effect upon the French and Vietnamese will and intention to resist., unless such ex- pansion was of rich a. nature and rnagrAtude as to remove from Indochina the threat presently posed by the presence of large numbers of Chinese Communist forces near the China border and by Chinese Cotmnunist logistical aid to the Viet Minh forces Po1i.ti.cnl, military, and economic developments elsewhere in Southeast Asia? Po-! itA cal? rd.? itary r*nd e conomi.c developments elsewhere in South- east Asia are of significance to t he French and Indochinese will and intention to resist to the extent that such deve3.oprrents increase or decrease the likeli- hood that the anti-Communist position in Indochina will be out-flanked, For example, Communist acquisition of control of Burma would constitute at least a potential threat to the anti-CommUraist position in Indochina, and would probably tend to discourage French and Indochinese will and intention to resist, 2, What trends in French-Indochinese capabilities to resist or reduce Viet Minh-Chinese Communist pressure are probable? a. In trained manpower, organized forces, and material supply (including Us aid)? No significant changes in the Fretcho.Indochinese capabilities is expected to occur during the period of this esbime, The FAEEO are expected to receive sufficient logistical support under MDAP to maintain the present level of operations. There is a current shortage of pilots and trained maintenance technicians, and the ability of the French to\supply sufficient personnel to support additional aircraft is questionable, No appreciable in- crease in air defense capabil5ties by Mid-1953 is evident, as the FA1EO are not expected to acquire F-86 jet aircraft prior to mid 19530 B, 1. What trends in Viet Minh-Chinese Communist capabilities are probable through mid-1953 assuming a continuation of the present situation in Korea: d, In terms of Chinese Communist ability to commit combat forces in Indochina? The Chinese Communists now have, and will continue to have through mid==1953, sufficient air strength in jet and piston aircraft to =able them to launch damaging attacks against French-Vietnamese installations iaangqTonki.ng, without appreciably lessening the present scale of Commvnist Approved For Release 2000N829:CIARDP]91lLioi9p#jA$,ions in Korea.

Although these preparations could be made b-z r2id='1953, there is no reliable evidence that they have r=:t begun, 2 Vrtt of ect would an expansion of war in Korea or a cease-fire in Korea have on Communist capabilities in Indochina? An expansion of the war.,in Korea would presumably include expanded Communist air operations, and therefore place a further limit- ation on Communist capabilities to coavnit air strength to Indochi.nae iii the event of a ceasefire in Kweay The Chinese Communists would ho capable of employing, for sit, operations in Indochina, all or any part of their present air force in being when released from its Korean mission, :subject only to logistical and air facilities limitations in the Indochina- China border area, )gai.n'.and., PLC'? +.t. is c onsi.der ed 0nt nve -a)1.
