This port consists of three pierN9FPAing from Pier Nos. 1 to'3, and two
managed by
fishing ports. The three piers are A the Najin Branch
(FB081765; N42-14, E130-1B; 7240 X) under the jurisdiction of the Ch'ongjin
Bureau
Port Office, Maritime Transportatio , iiiinistry of Transportation. Of the
two fishing ports, the Main Fishing Port is managed by the Najin Shipyard,
and another, known as the Anjuri Fishing Port, was under the management
of the Najin Fishing Station. According as the Najin Shipyard will be expa-
nded a sluice will be constructed 50X1 -HU M
between the Pier No. 1 and Pier No.2 so as to be used as "Sluice Joc_.."
1. Pier No.l:
Along the walls of the pier, vessels including two 60-tor. small-gun
boats, two 40-ton mine-sweepers and two 100-ton coastal patrolling
boats were always moored, and these vessels were used by the students
of the Najin Naval Staff College (located FB064793; N42-16, E130-18;
7240 I) for their training. No civilian vessels were allowed to moor
at this pier.
2. Pier No.2:
there was a sunken Japanese merchant ship (See
Attachment) at a point about 100 meters from the wall at the end of
the Pier No.2 where the merchant ship was sunk by a deadly strike of
a Soviet air borne torpedo at the time when the World ':Jar Ii was about
to end. Because of this sunken boat, a vessel more than 1,000-ton
class was unable to moor along the wall at the end of this pier.

During the Japanese occupation, vessels ranging from 2,500-ton to
3,500-ton class were able to moor along the left wall of the pier,
and 3,000-ton to 3,500-ton class along the right vrall of the pier*

to accommodate vessels more than 2,000-ton class because sediment was
deposited 1 to 1.5 meters high, and because no dredgingtperation was
performed in the port during the period from 1945 to November 1959.
3. Pier No-3:
50X1-HUM
this pier was able to accommodate vessels of 5,000-
ton to 6,000-ton class. Since no dredging operation was carried out

a sunken Japanese merchant ship (See Attachment) was
located at a point about 10 meters from the wall at the end of the pier
where the merchant ship was sunk by a Soviet air borne torpedo at the
time when the World Jar II was about to end. Because of this, no vessels
more than 1,500-ton class were allowed to moor along the wall at the
end of the pier. On a day when it is southerly or southeasterly wind,
only vessels less than 400-ton class were able to moor along the wall

1. nigh tension cable:
The high tension cable with transmission capacity of 3,300 volts was
constructed jointly by the Engineering and Power Department, the
Najin Shipyard and the Najin Electricity Transmission and Distribution
Department 50X1-HUM
Before the outbreak of the Korean War, the high tension cable was
laid underground. The high tension cable was presently laid along
the towers about 7 meters high from the surface of the ground.
The electricity transmitted through this high tension cable was used
,break up
to Iv the sunken vessels within the Najin Port, mot as well
and
as to operate such machines as cranes established in the po quarrying
machines.
2. Flood-light steel towers to illuminate vessels:
There were three flood-light steel towers, each of which was placed
at each pier. 50X1-HUM
These flood-light steel towers were constructed during the Japanese
occupation, and during the Korean War a part of them were damaged
by the bombardment of the UN air force. Following the Armistice,
they were rehabilitated by the Najin Power Transmission and Distribution
Department. The three flood-light steel towers were same in their
bars
structutes; each was constructed with 3-inch steel angler in square type.
Each flood-light steel tower was about 2.5 meters wide, 30 meters high,
and at the top of the tower there was a flood-light that was about
40 centimeters in diameter. Each flood-light was assembled with 500-W
the.area at the angle
