The Chaho-Nodongj,gu Submarine Base Complex at 40-11`-33N 128-39-
0lE is an excellent example of continuing North Korean efforts to up-
grade naval installations in consonance with continuing acquisitions
of naval units. The presence of a large probably concrete arch-roofed
structure with a span of approximately 65 ft over partially completed
excavation near the shore line indicates a submarine pen is possibly
under construction. Extensive construction is underway adjacent to
this structure.
The development of the Chaho Complex apparently was part of a
naval facility expansion proprr:.m probably initiated during rhich
also incorporated two other installations. Both the Songjon ando
Naval Base and Missile Support Facility, north of Wonson, and the
Mayangdo-ri Naval Repair Facility, adjacent to the Mayang-do Submarine
Base, were constructed in the same time frame as the Chaho Submarine
Base. The growth of this facility has been unique in that it apparent-
ly began prior to I las a small facility for patrol craft, but
as construction progressed base expansion overran the village of Chaho.
The large T-head subm rine prier was in the initial stages of construc-
tion in the The facilities comprising the Chaho
Complex are extensive and varied, and the disproportionate number of
military-type buildings within the complex suggests that this installa-
tion has support or training functions in addition to being an
operating base.
Berthing area facilities include one T-head pier (exclusively
associated with submarine activity, four quays (one has a butler-
type building and is normally associated with surface units, including
S0-l PGM and KOMAR PTG), four fenced storage buildings, and 15 other
storage/support buildings.
Support facilities include eight administrative-type buildings,
50 barracks, four multistory barracks/administration buildings, and
numerous support buildings.
