(SWN) SIGNIFICANCE: A BOW-MOUNTED SONAR DOME HAS BEEN CONFIRMED ON A ROMEO DIESEL ATTACK SUBMARINE (SS). THE PRESENCE OF THE DOME INDICATES THAT THE CHINESE HAVE DEVELOPED AN IMPROVED SONAR FOR THE ROMEO SS. 2. (SWN) REMARKS: THE ROMEO SS WAS ON THE MARINE RAILWAY AT ZHANJIANG SHIPYARD NORTH, PROBABLY FOR REPAIRS/MAINTENANCE. THE PORT SIDE OF THE ROMEO SS HULL BELOW THE WATERLINE WAS VISIBLE, REVEALING A BULBOUS SONAR DOME MOUNTED ON THE LOWER PORTION OF THE BOW. THE DOME EXTENDED TO THE SIDE AND FORWARD OF THE BOW. A SECOND ROMEO SS, WHICH WAS ON THE REPAIRWAYS, APPEARED TO HAVE A SIMILAR BULBOUS SHAPE ON THE LOWER BOW; HOWEVER, DUE TO THE SUBMARINE'S SHADOW, IT COULD NOT BE CONFIRMED. (SWN) THIS IS THE SECOND CONFIRMED MODIFICATION BY THE CHINESE TO IMPROVE THE SONAR CAPABILITY OF THE ROMEO SS, THE OTHER BEING THE THREE BLADE-SHAPED SONAR HOUSINGS THAT WERE IDENTIFIED ON A ROMEO SS AT XIAOPING DAO SUBMARINE BASE 3.
