TV* USSR now is believed to have two models of gag liquefying
equipmjrt ultti respective capacities for productionilogrcmt, of liquid oxygen por hour- It has, not teen possible, however, to establish whether these models ure In series production. Previously identified Soviet liquefying equipment ranged ln capacity rrorailograms per hourilograms per hour.
Soviet requiremunia for liquid oxygen probably are increasing despite decreased requirenenti for this product in strategic nlislles. It should te noted, hew-ver, that the USSR nay have been negotiating7 for purcbaee5 ton/dsy liquid oxyeen/nitrogen plant developed in the UScmerly used by tha Air Force to produce liquid oxygen forssile3
The Soviet requlre-ieot for liquid oxygen for space missions probably will reaain fairly constant. Industrie! requiren-nts for oxygen are increasing in the USSR end presumably will be -net in part by increased output of liquid oxygen because of the grceter ecOOGBy resulting from shipment of oxygen in liquid fora.

TV* USSR it believed to be coajetent in the are* of liquefaction technolQQr, although it nay exjerlcnce difficulty in series manufactureols Incorporating advanced technology. Some of tho more advanced, Liquefaction equipment is mode at institutesirid nesIs.
As noted, the present military/strategic applications for liquid oxygen in the USSR are believed to be fairly United. Presumably liquid oxygen Hill be of even lees strategic importance ns manufacture of large solid propellent missiles is expanded. B. gust European Ccmn-jrlst Countries
East Gerranyhe only eojor producer of oxygen liquefying equipDcnt among the East European Coaaauiist countries- henlcel plant atanufactures liquid oxygen units thatapacitycductlcn0 kilograms par hour. Oxygen liquefying equipo&nt also is produced In East Geraony at Rudisleben, but capacities of the units currently tar.ufactured are not known. Earlierad indicated that the output of the Rudisleben plant included soe* noblle oxygen units.
Inasmuch as domestic output la insufficient to satisfy reqijirewntn, some of the East European countries have purchUBed oxygen cquipirent and/or technology from Free World countries or have conducted negotiations for such purchases. 7 Rimania purchased an sir seporoUon unit from th- IK that ray have included mvhI.

France for purchasexygen liquefying equipment and transport tanks. Eact Germany has requested technical data for tho design andof air separation Flants, including data for production of liquid oxyrnn.
II. Containers for Storageh-sjr,riqurfipfl Gases (l)
Anong the Coerounist countries, the USSR is the chief producer of containers for liquid oxygen. East Cer-any being the only other significant producer. Soviet tankage identified previously has included containerstorage capacityilograms of liquid oxygen and tank cars carrying V. ton3. Both types are Insulated with urea-formaldehyde foam and evaporation losses reportedly amountercent per day for the containersercent per day for the tank cars- ho USSR revealed the developaent of en in;roved liquid oxyqra tank, thehatacuum Jacket and powder Insulation claimed to reduce evaporation lossesercent per day. Thiskld-mounted tank for use at airfields,apacity for storageons of liquid oxyeoo. Details of other Soviet nodels of storage equtpaent for liquid oxygen and liquid nitrogen are described in the attached translationoviet article published in The article indicates that substantial develaprent of new isodels is underway, although we believe that series production of at least some of the tytes described has not yet beer, attained.
