The baseline ships combine Uran anti-ship missiles, Redut or Kortik air defense depending on hull, Paket-NK torpedo launchers, and a Ka-27 helicopter facility in a reduced-radar-signature corvette that remained in active Russian service during the 2014 Russia-Ukraine War.

Documented deployments tie Udaloy-class ships to Russia's Syria intervention and counter-piracy patrols off Somalia.

Hangzhou and Fuzhou were Project 956E ships centered on Moskit anti-ship missiles and Shtil air defense, while Taizhou and Ningbo were improved Project 956EM ships with revised combat systems, Kashtan close-in defenses, longer-range Moskit missiles, and one fewer 130 mm gun. Later Chinese refit reporting describes domestic sensors, vertical-launch HQ-16-family air defense, and YJ-12 anti-ship missiles replacing the original Russian systems on at least the first 956E pair.
