PROBABLE NEW RADAR-CONTROLLED ANTIAIRCRAFT GUN ON OSA PTG
SHANGHAI NAVAL BASE AND SHIPYARD HUDONG, CHINA SWN
1. SIGNIFICANCE: A PROBABLE NEW RADAR-CONTROLLED ANTIAIRCRAFT GUN WAS
BEING ED ON TWO OSA MISSILE ATTACK BOATS (PTG) AT IIUDONG. THIS
GUN WILL BE A SIGNIFICANT INCREASE TO THE OSA DEFENSIVE CAPABILITIES.
(SWN)
2. REMARKS: ONE OF THE TWO PTG, WHICH WERE PLACED ON THE BUILDING WAYS
HAD THE PROBABLE NEW ANTIAIRCRAFT25X1
GUN INSTALLED ON A MOUNTING RING FORWARD OF THE SUPERSTRUCTURE. THE GUN
FOR THE SECOND OSA HAD NOT BEEN INSTALLED AND WAS ON THE CRANEWAY NEXT
TO THE OSA'S. THE PROBABLE NEW GUN APPEARED TO BE SIMILAR IN DESIGN TO
THE SOVIET AK-230 ANTIAIRCRAFT GUN. A SPHERICAL RADOME, WHICH WOULD
HOUSE-THE RADAR DIRECTOR, HAD BEEN INSTALLED ON BOTH SHIPS ON THE AFT
EDGE OF THE DECKHOUSE BETWEEN THE SECOND SET OF THE CSS-N-1 MISSILE
LAUNCHERS. (SWN)
ANALYST'S COMMENTS: THE ADDITION OF A RADAR-CONTROLLED ANTIAIRCRAFT GUN
WOULD BE A SIGNIFICANT IMPROVEMENT TO THE VESSEL'S DEFENSIVE
CAPABILITIES AND WOULD PROBABLY ALSO BE A PREREQUISITE ON ANY SALE FOR
EXPORT. THE CHINESE HAVE BEEN DEVELOPING A RADAR-CONTROLLED
ANTIAIRCRAFT GUN SINCE THE LATE 1970'S, AND INSTALLED ONE IN 1980 ON A
OSA WHILE IT WAS AT HUDONG. THE INSTALLATION OF THE NEW GUN ON THESE
TWO SHIPS INDICATES THAT THE GUN PLACED ON THE OSA IN 1.980 HAS PROVEN
SUCCESSFUL. THE SUBSEQUENT DEPLOYMENT OF THIS WEAPONS SYSTEM ON
ADDITIONAL NAVAL COMBATANTS TO ALL THREE FLEETS WOULD SIGNIFICANTLY
UPGRADE THE NAVY'S DEFENSIVE CAPABILITY. (SWN) 25X1
