The Type 052C has two (one front, one rear) Type 730 close-in weapon system (CIWS) for short-range air defence. Two seven-barrel 30mm Type 730 CIWS are located both sides behind the bridge. The weapon system has a maximum rate of fire of 4,600~5,800 rounds/min.
I think the description is a bit unclear. It does mean 2 x Type 730 CIWS guns total, and both are located behind the bridge, or is it 4 guns, with 1 front, 1 rear, and 2 behind the bridge?
