Kanwa analyzed the structure difference between 314 and 324 subs which is visiting HK. The appearance of 324 shows that PLAN very much concerns the upgrading work for 039A. For more details, see Kanwa issue May 30. Kanwa has noticed that China imported more diesel engines from an EU country for building further 039A. The pick of manufacturing type 039A/B is under way. <Kanwa photo HK> In the exclusive interview with Mr. G. Makalov, the deputy designer of Russian Rubin Central ship design Bureau, he told Kanwa in 1997 that the sail of 039A is too high, which may cause the instability under water sailing. Many of the Chinese military magazines translated the interview. Type 039A/B showed in HK indicated that redesign of the structure includes lowing down the sail. Judging from the upgrading conception of 039A, Kanwa believes that PLAN may have accepted the reference from Pakistani Agosta 90B. <Kanwa Photos> Domestic HHQ7M SAM has replaced the original French Crotal SAM in No.112 DDG. Chinese military industry source says that HHQ7M has a more advanced function for the SSM-intercept capability. The brochure of HHQ7 explains that launch altitude of this missile is 5m. <Kanwa Photo Kwok Wing Keung> The launchers of HHQ7 is slightly different from that of Crotal SAM. <Kanwa Photo Kwok Wing Keung> SAM for 053H2G. <Kanwa Photo Kwok Wing Keung> YJ8-3 SSM has replaced YJ8-1A in 053H2G. Chinese claimed that this missile has a capability for terminal supersonic attack with a small booster. However, Kanwa did not see the existing booster. Chinese released more information of 120km range YJ8-2 SSM launcher in DSA 2004.

The system consists of direction finding antenna, the active electronic countermeasures and frequency measurement antenna. China released more details of this EW system in DSA 2004. It is capable of dealing with 5 targets coming from two sides according to Kanwa DSA 2004 report. <Kanwa Photo>
