The Chinese ships are best read as two Russian export batches followed by a Chinese modernization path. The first pair preserved the Project 956E layout on hulls completed for China, while the later 956EM pair incorporated more changes before delivery.
| Batch | Ships | Source-backed distinction |
|---|
| Project 956E | Hangzhou (136), Fuzhou (137) | First two Chinese deliveries, centered on Moskit anti-ship missiles and Shtil/SA-N-7 air defense before later refit reporting described domestic replacements. |
| Project 956EM | Taizhou (138), Ningbo (139) | Improved export ships; Forecast International describes longer-range 3M80MBE Moskit missiles, Kashtan CIWS, a revised combat-control system, and removal of the aft main-gun turret. |
| Modernized 956E configuration | Hangzhou and Fuzhou reported complete or returning after refit | Chinese reporting and defense press coverage describe replacement of Russian missile and electronic systems with domestic VLS, HHQ-16-family air defense, YJ-12 anti-ship missiles, and upgraded sensors. |
