Chinese destroyer Hefei (174)

Hefei (174) is a Type 052D destroyer of the People's Liberation Army Navy. She was commissioned on 12 December 2015.

Development and design
The basic ship type and layout of the Type 052D guided-missile destroyer is the same as that of the Type 052C destroyer, but compared to the earlier Type 052C destroyer, the Type 052D superstructure has a larger inclination angle and provides better stealth performance. At the same time, the 052C helicopter hangar is located The left side of the hull axis was changed to the center axis of the ship on Type 052D; a pair of small boat storage compartments were added on both sides of the hangar, similar to the design on the Type 054A frigate.

The close in weapon system is composed of a H/PJ-12 short-range defense weapon system located in front of the bridge and a 24 Hongqi-10 air defense missile system located on the top of the hangar, which is combined to form a ladder interception. The original 100mm naval gun was replaced by a higher height and better stealth model H/PJ45 naval gun. On May 13, 2019, the extended version of the 052DL was exposed. The hull of the 052DL is basically the same as the 052D, but the helicopter deck is lengthened to prepare for the Zhi-20 to board the ship.

The Type 52D is the first Chinese surface combatant to use canister-based universal VLS, as opposed to the concentric type VLS carried aboard earlier vessels. 64 cells are carried; 32 forward and 32 aft. The VLS is reportedly an implementation of the GJB 5860-2006 standard. The VLS may fire the extended-range variant of the HHQ-9 surface-to-air missile, YJ-18 anti-ship cruise missiles, and CY-5 anti-submarine missiles.
