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.

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.

The present aircraft engine industry would probably be unable to neatequires* nt, but there ie eono evidence that an expansion ie under way*

6c There are no serious economic limitations on Soviet capabilities for the manufacture of electronio air defense materiel in the fields of power or most typos of basic plant machinery0 However, the Soviet Bloc is at present partly dependent upon Western sources of supply for speoializjd critical production materials such as ductile tungsten and molybdcmaaiamond dies, good mice, and thin capacitor paperc The USSR is
taking atepa to reduce this dependence which will probably decreaseh"

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*
