NEW CHINESE COMBATANT
SHANGHAI SHTPYARf rT4Trr_uSTN, CHINA
25X1
1. (S/D) SIGNIFICANCE: A NEW CLASS CHINESE SUBMARINE CHASER,
THE "CHIU-B" (NPIC INTERIM DESIGNATOR) HAS BEEN LAUNCHED AT
SHANGHAI SHIPYARD CHIU-HSIN. THE CHIU-B APPEARS TO BE A
FOLLOW-ON DESIGN FROM THE HAINAN-CLASS SUB CHASER AND
PROBABLY HAS IMPROVED ENGINES, ADDED AIR DEFENSE CAPABILITY,
AND NEW FIRE CONTROL RADAR.
I
2. (S/D) REMARKS: THE CHIU-B WAS FITTING OUT IN FRONT OF THE
BUILDING WAYS, INBOARD OF TWO HAINAN-CLASS SUBMARINE CHASERS
(PCS). IT APPEARS TO BE A FOLLOW-ON FROM THE HAINAN PCS
DESIGN, BUT DIFFERS IN SEVERAL IMPORTANT RESPECTS. THE NEW
PCS THAN 25X1
THE HAINAN) AND HAS A 7.2-METER BEAM. THE ADDED LENGTH IS
MOST NOTICEABLE IN THE SUPERSTRUCTURE AREA. TWO NEW PROBABLE
AIR DEFENSE MACHINE GUNS (ADMG) HAVE BEEN MOUNTED, ONE
FORWARD OF THE BRIDGE AND ONE ON A PEDESTAL AFT OF THE STACK.
(S/D) A NEW SQUARE-SHAPED STACK CONTAINING FOUR PROBABLE
UPTAKES WAS ALSO OBSERVED IN THE SUPERSTRUCTURE AREA, AFT OF
THE MAST. THE NEW STACK INDICATES THAT THE CHINESE HAVE
INSTALLED A NEW PROPULSION PLANT IN THIS VESSEL, VICE THE
FOUR DIESEL ENGINES FOUND ON THE HAINAN. THIS NEW ENGINE
CONFIGURATION COULD REPRESENT A SIGNIFICANT IMPROVEMENT OVER
THE PERFORMANCE CAPABILITIES OF THE HAINAN-CLASS ENGINES.
(S/D) THE CHIU-B ALSO HAS A NEW 2.0-METER DIAMETER PROBABLE
FIRE CONTROL RADOME MOUNTED ON THE MAIN MAST AFT OF THE
BRIDGE. THE RADOME APPEARS TO BE SIMILAR TO THE TYPE
INSTALLED EARLIER ON AN OSA-CLASS MISSILE ATTACK BOAT AT
(SHANGHAI NAVAL BASE AND SHIPYARD HUTUNG IT 25X1
WOULD BE LARGE.ENOUGH TO ACCOMMODATE A SMALL ANTIAIRCRAFT GUN

FIRE CONTROL SYSTEM RADAR, SUCH AS THE SOVIET DRUM TILT OR
THE DUTCH M20. THIS PROBABLE FIRE CONTROL RADOME,
