Who said without?The choice of a Type 382 radar seems pretty interesting. That's a full on military-grade air search radar, far more powerful than anything else I can think of a cutter using. Without SAMs I'm not sure what the point is. Maybe just the ship had excess power and they figured why not?
Chinese CG ships have very obvious mobilization capabilities. Just not for peacetime.
p.s. CG 052 is an interesting reversal to something not unlike 052B.
