CRUISE MISSILE LAUNCHERS, TWO ON EACH SIDE MOUNTED IN
TANDEM, AND ANTIAIRCRAFT GUNS MOUNTED ON THE CENTERLINE,
FORE AND AFT. THE FORWARD PORTION OF THE DECKHOUSE HAS
BEEN ERECTED ON ALL THREE UNITS AND THE MOUNTING RINGS
FOR THE ANTIAIRCRAFT GUN SYSTEMS ARE IN PLACE. THE
CONFIGURATION OF THE WEAPONS SYSTEMS AND THE SIZE OF THE
VESSELS ARE SIMILAR TO THOSE OF THE SOJU PTG, BUT DIFFERS
FROM EITHER THE SOJU OR OS A I PTG IN THAT THE BRIDGE
AREA/FORWARD PORTION OF THE DECKHOUSE IS NOT THE SAME, AND
THE CRUISE MISSILE LAUNCHERS ON THE CHONGJU PTG ARE MOUNTED
CLOSER TO THE STERN, ENTIRELY AFT OF MIDSHIPS.

(S/D) THE CHONGJU HULLS HAVE BEEN AT NAMPO SINCE 1974. AN
EXPERIMENT INVOLVING STYX MISSILE LAUNCHER COVERS AND ONE
OF THESE CHONGJU HULLS WAS OBSERVED AT THE SHIPYARD DURING
JUNE 1977. HOWEVER, NO LAUNCH RAILS WERE MOUNTED ON THE
VESSELS AND THE LAUNCHER COVERS WERE PLACED ON BUT NOT
AFFIXED TO THE DECK OF ONE UNIT. BETWEEN MID-1977 AND
MID-1981 NO MORE THAN FOUR STYX MISSILE LAUNCHER COVERS
WERE OBSERVED AT THE SHIPYARD AND THE CHONGJU PROGRAM
APPEARED TO HAVE BEEN ABANDONED. TWO OF THE FIVE CHONGJU
HULLS AT NAMPO WERE CONFIGURED AS PATROL CRAFT AND LAUNCHED
DURING 1981. BY AUGUST 1981 EIGHT MISSILE LAUNCHER COVERS
WERE NEAR THE THREE REMAINING CHONGJU HULLS, AND 12 WERE
OBSERVED BY MARCH 1982. THIS ACTIVITY PARALLELS THE
SOJU PTC CONSTRUCTION PROGRAM AT NAJIN SHIPYARD NO. 28.
THE FOUR EAST COAST CHONGJU UNITS WERE UNDER MODIFICATION
TO A PATROL CRAFT CONFIGURATION AT NAJIN SHIPYARD NO. 28
DURING 1981; TO DATE ONLY ONE CHONGJU PC HAS BEEN LAUNCHED
THERE.
(S/D) IN ADDITION TO THE ABOVE ACTIVITY,
OF NAMPO, OF NAJIN, REVEALED FURTHER
MODIFICATION TO TWO OF THE THREE PREVIOUSLY LAUNCHED
CHONGJU PC. TWO LAUNCH RAILS FOR DEPTH CHARGES HAD BEEN
MOUNTED ON THE STERN, AND POSSIBLE ASW ROCKET LAUNCHERS
WERE OBSERVED ON THE WINGS OF THE SUPERSTRUCTURE OF EACH
VESSEL (GRAPHIC 2 OF 2). THIS MODIFICATION WILL FURTHER
AUGMENT THE NORTH KOREAN NAVY ASW CAPABILITY.
