Completed tank engines were crated specially, and shipped by rail to the KRIVAN
tank manufacturing plant, the location of which I do not know. The Diesel -"riven
Skoda tractorsproduced at the Vorosilov Works either have rubber tires, or are of
the caterpillar type. Finished tractors are shipped by rail; I am not aware of their
final destination, or of the number of tractors produced. The antitank. :121es
manufactured at the plant are 12 mm and have a magazine for 10 rounas and a 50X1
collapsible steel. bipod. Comeleted guns, 13.5 cm, 15 cm, and 10.5 cm caliber were
shipped from the enterprise by caterpillar tractor to Trencin, and some were loaded
directly onto railroad cars.
I also saw guns loaded at this
plant which resembled those pictured in the us che Artillerie handbook, Illustra--
50X1 tion eight. Artillery projectiles were shipped
by rail in wooden crates. Each crate carried one projectile and weighed about 80
kilograms. These projectiles were shaped approximately thus:
jWC:47
The Vorosilov Works so repaired old guns and tanks. I observed four-barrelled 6 cm
antiaircraft guns standing in the courtyard. The guns were mounted on a rubber tired
gun noun." ana eould be dismounted from it at will. They had been shi)ped to he
factory for repair.
Completed excavators wer shilped, one a week, from the factory by rail.
4. Technical equipment: The entire enterprise is equipped along modern lines. Sub-
terranean workshops have electric ventilators, ele,ators, and neon (fluorescent)
lighting.
The workshops have mobile cranes and very good machinery. A public address system is
installed in every room in the factory, and all telephone cables are buried in the
ground. Tho enterprise has a ?branch railroed. line, andet:hetracks are arranged so
that each major assembly shop has the use of a separate track. Small battery-operated
factory trucks, called "Jesterky', (sa1amander4 are used for transporting material
from one shop to the other. The factory also owns truCks and buses for conveying
workers to and from work. for description of buildings and installations see
Enclosures A and C.7
5. Personnel: The enterprise management is located directly within the factory. The
entire enterprise employs about 9,000 workers, in addition to apprentices. They are
divided approximately a:; A)liows: 3,000 skilled workers, 2,000 women, 600 clerks,
and the remainder, auxiliazy hands. There are also several Soviet engineers; two of
them are (Thu) Krnov, and (fnu) Vasilovic.
6. Wages: An auxiliary worker received 3,500 crowns a month, a retrained worker at
5,000, and a skilled worker about 7,000 to 8,000 crowns "take-home" pay per month.
7. Political Affiliation:, About 70 per cent of the personnel at the plant are Communist
Party members; of these only about 30 per cent are "true" to the regime.
8. Shifts: The factory operates on a three-shift system.

10. Security: The enterprise has about 30 guards who are on duty at the gatehouse, wear
green uniforms.with red shoulder boards, and are armed with pistols. There is also
a factory militia whose members wear dark blue overalls, and a red arm-band on the
left sleeve. The militia is armed with rifles. I do not know the numerical strength
of the militia. Militia members attend regular training sessions held in a training
field near the factory (and belonging to it). In addition to the above security
forces, there is a permanent military guard assigned to the factory.Til :unit
t
commutes from Trencin and consists, in all, of one plus one plus 20 men sic7. The
soldiers guard the subterranean workshops and patrol the outside of the factory
premises. There are, besides, six SNB members at the 'enterprise, whose function it is
to guard the factory. The enterprise fire department consists of 30 men; its equip-
ment consists of a motor pump.

.11. Miscellaneous: Water used by the Vorosilov Works was supplied by the waterworks .51c7,
and the hydroeleCtric_plant supplied, the motive power used throughout the enterprise.
12. Worker Morale: For the most part, the workers were dissatisfied, because, compared
to the relatively heavy work load, their earnings were low. The Communist management
tried very hard to disseminate Communist propaganda by use of the public address
system, and during the weekly political training, attendance at which was compulsory.
Communist Party members held special membership meetings at the factory.
13.
Toward the end of March 1952, a serious explosion in the factory resulted in the
death of about 4.5o peop_Le, and the injury of about Goo more. The cause of the
explosion was not determined, though the State police heirthearings throughout the
factory, and several people were arrested. T: site of the, explosion was an underground
workshop 5ee Enclosure A, circled number 397. Damage to the shop was so great that it
