The basic ship type and layout of 052D is the same as that of 052C, but its detailed configuration and equipment have changed considerably. First of all, the original 100mm naval gun was replaced by a turret with higher height and more perfect stealth shape; According to the photo of the gun body, this is a domestic version developed by China with reference to the modern AK- 130 130mm 70 times diameter naval gun.
In addition, the inward contraction angle of the two sides of the ship building is larger, which narrows the front of the bridge and enlarges the inclined plane where the phased array is installed on both sides. 052D is replaced by a new type of phased array, which tends to be square in shape, without the arc cover of 346 phased array, and the area is larger.
This new phased array was first exposed on the Bi Sheng comprehensive test ship in June, 20 12. As the cover of the former 346 air-cooled system was cancelled, it shows that China has developed a liquid cooling system (cooling inside the antenna) to cooperate with the active phased array system. The output power and continuous operation performance of the new phased array should be better than that of the 346 radar because of the larger cooling capacity of the liquid cooling system and the larger antenna array.
The outline and configuration of the rear hull of 052D are basically the same as that of 052C, but the structure of the rear ship building has obviously changed. First, the hangar moved from the left to the middle position, and closed boat cabins similar to 054A were added on both sides. The rear mast used to carry the Yagi antenna of the 5 17HA radar also moved forward, because a set of vertical launching systems was set up between the rear mast and the hangar, thus moving the 5 17HA radar forward and away from the missile jet.
The domestic 130mm single-barrel naval gun of 052D is H/PJ-38, which was developed by Zhengzhou Institute of Mechanical and Electrical Engineering in 2005. It is copied from Russian AK- 130 naval gun, and the production work is undertaken by Inner Mongolia No.2 Machinery Factory. The original AK- 130 130mm gun body used two-way ammunition supply, while the China version changed to one-way ammunition supply in order to reduce the weight and simplify the structure.
In order to save weight, China version 130mm naval gun uses a large number of aluminum alloy components without affecting the structural strength. The total weight of China 130mm naval gun is more than 50 tons, and the turret with stealth appearance is made of glass fiber. Originally, the firing rate of AK- 130 single shot was between 10~40 rounds per minute, so the performance of China version should be similar. China version 130mm naval gun can use grenades and anti-aircraft high-explosive bombs similar to AK- 130.
The improved 052C also replaces the original wheel-type vertical launcher dedicated to Haihongqi -9 air defense missile with a new type of vertical launcher. Four groups of eight-pack vertical launchers are arranged in front of the bridge, while the hangar structure is equipped with another four groups of eight-pack vertical launchers, so there are 64 units in total.
Compared with the thermal vertical launcher previously used for Haihongqi-16 shipborne air defense missile, the new vertical launcher of 052D is square, with similar overall dimensions, but the exhaust duct is cancelled to make room for the missile launcher (Haihongqi -9 air defense missile is cold-launched, and no exhaust duct is needed), so the length and width of each missile launch slot are increased compared with the original one.
052D's new vertical launcher is in accordance with the national military standard GJB 5860-2006, which was promulgated by China National Defense Science and Technology Commission on February/2006 15 and implemented on May 1 2007. That is, the first general, cold and hot shipborne vertical launcher designed by "General Requirements for Universal Vertical Launcher of Surface Ship Missiles" can be compatible with cold launched HHQ-9 air defense missiles and other cold/hot projectiles.
It is said that 052D is equipped with HHQ-9 air defense missile, as well as developed and vertically launched Eagle Strike-18 supersonic anti-ship missile. The details are unknown, and it is not clear whether more other types of missiles are being further integrated into this launcher (such as rocket-assisted guided torpedoes, anti-ship cruise missiles and even ground cruise missiles).
In the close-range defense, a 30mm close-range weapon system of model 730 is still maintained in front of the 052D bridge, but a HQ- 10 short-range air defense missile launcher newly introduced by China in the 20th/10th century is refitted above the hangar, using a 24-pack configuration. Originally, 052C was used to install the position of anti-ship missile launcher (before the hangar structure), and 052D was used to install four groups of eight-pack vertical launchers.
