27 Observation of tha activities of tha fighter alomenta of the tactical air armies shows that theyonsiderable proportion of their tactical training to ground controlled intercept problemso This tends to oonfira other reports that the tactical air are reeponeibla for intercepting hostile aircraft in their aaaignsd territorial are as The probable assignment of tactical air armies to the multiple missions of seeking air superiority, interdict ion, ground support, and air defense wouldroblem in case these air armies were withdrawn from their present areas in -vent of warn In this oaae we believe that as the taotioal air army fighters moved forward, IA PVO fighters might move in end assume tho fighter defense responsibility in the areas vacatede This would resulthinning of air defeiuwe unless additional IA PVO units were created, as would

be likely- Another possibility would be for tbe Taotiesl Air Armies concerned to be assigned additional fighter strength to provide both for ground support to the land armies and defence of tbelr present territorial areas as well- In either event, some dsaline in Soviet Interception capabilities night result in the early stagear-The fighter units which deployed forward in support of the ground forces would be assigned tha mission of providing air defense Ln the area between the front lines and the forward limit of IA PVO responsibility, and their operations In these anas would be tied ln with the PVO system in the USSR itself.

Present actual Set fighter etrength (ell in the OPL) is estimated et eighty planes0 There is recent evidence that similar air defense organisations are also being established In Czechoslovakia and Hungary^

30, The intercept capability of Satellite fighter units ie considered negligible against high flying boabers and probably only fair against medium and low flying bombers* with tho degree of effective nana directly rolated to the vtstbilityo The main ruUanoo for interception of hostile aircraft rests at present on tho Soviet air force unite stationed within these countries.-, However, Satellite interception capabilities will probably

itself and probably ia boinp integrated into tho over-all plana for dcfsnse of the Soviet Far East* Available evidence indicates that for purposes of command and control this area is divided Ksographioally into air defense regions. As jet fighter strength has increased, the disposition of jet units has spread generally fron Kanehurln into China proper0 Concentrations of jet fighters, augmented by piston-engincd units, exist in southern Manchuria, thear*a, Shanghai, Hankow, and Cantono These forces could be used against air attacks launched across the foregoing areaa against Siberia.

An airfield Improvement programatural corollary to the re-equipment of units with higher-performance airoraftc In the past three years the Soviets have accelerated developmenttring of airfields withrneet or longer in the Western Satellites stretching south from the Baltic Sea toward tho Black Sea, and since the beginning1 there hasarked increase in runwaysfeet or longer. Tho Soviets have also devoted increasing attention to jet airfields In tbe woaturn part of the Soviet Union and have continued to improve airfields in the Moscow area. There hasteady development of airfieldo ln the Cauoaaua and extensive work on air bases in China-. Air facilities along air routes fron Central and

From the etandpoint of defense, this airfield programetwork of baees capable of supporting large-scale jet interceptor operations^


33. Soviet entlairoreft artillery (AAA) capabilities have smrkedly inoreeeed in tho pent few years, owing largely to tho introduction of new nodal guns and fire control equipment* At present about one-third of the known Soviet AAA strength is disposed in the eastern and western peripheral areas of the USSR end ie available to protect key areas from hostile attackc

3b* Soviet AAA units consist of two distinct categoriee, strategic and tactical* StratoUc antiaircraft artillery, with heavy, medium, and light guns,earchlights, and barrage balloons, ia an integral pert of PVO Strany* It ie organised into PVO brigades, divisions, and corps*

35. Tactical antiaircraft artillery unite consist of independent divisions and the organic antiairoraft artillery within ground foroe units* Tho AAA division,trength of, is the basio antiairoraft unit and is allotted to the various fronts, army groups? and armies as requiredo The exact composition of these divisions varies, eome having two regiments of medium artillory and

Moreover, in the pivaent Soviet Amy ell ground combat units of regimental sis* and larger have erganio AA artillery, with light weapons predominating. The USSR haa0 of the9 AA guna, and we estimate that at09, guns are available.

16 The USSR la engagedrogram designed to atrentthen existing AAA defenses through the Introduction of the new estimatedm.m- guns and improved fire control equipment.-. These new weapons are probably now available In Boderate quantities around tba most lnportant areea.

However, observers from Moscow, Leningrad, and other strategic centers of the European Russian interioroticeable lack of passive defenseesutions in these areas. The types of caraouflago used by tha USSR in World War II and in Korea are indicative of those which will be employed in the future o Skillful uae of natural camouflage can be expected of Soviet military forces.

irfields in Kwantung Province, Sakhalin, and the Par East generally employ earth revetmunts for aircraft, large dispersal areaa, underground storage, and protected repair shopsc The 2bth Tactical Air Army in the Soviet Zone of Germany has prepared dispersed all craft revetments and conducts frequent air alerts to provide real' istie training. In Hungary andt has been reported that underground wartime command posts and filter centers have been

It is estimated that capacity to produce AA guns of all calibers could be increased to st0 and possibly0 guns per year, although this would ruquire an all" out effort* Any current limitation on the So volt AA gun production and utilisation is probably attributable tog (a) the relatively lower priority assigned to this program; and (b) present Soviet inability to provide adequate numbers of effective antiaircraft fire-control instruments. There ia evidence to indicate that this latter limitation is being overcome*
