re: PLAN Type 052 Class Destroyer
one thing i dont get with the Zumwalt is the naval gun? when they have cruise missles what is the need for naval gunfire? plus to use naval gunfire u need to first control the sea to get close to the shore, which means the enemy probably isnt that dangerous anyway, defeating the purpose for naval gunfire?
It's cheaper and you can carry far more shells than missiles.
Cruise missiles cost a lot of money, and you don't always have targets that require cruise missiles to take care off, and some targets are not even very well suited for cruise missiles.
Also, guns are effectively jamming proof, and has better reaction time at closer ranges. When your ship sees a coastal AShM launcher popping out from behind cover, it takes precious fewer seconds to aim the gun and fire a shell than to triangulate the position of the launcher and programme it into a cruise missile.
Besides, cruise missiles have ranges in the thousands of kms, guns have ranges that do not get close to triple digits. They are not exactly doing the same job to start with. It's like asking why fighters carry WVRAAMs when they could carry more BVRAAMs instead.
