CNS Lanzhou (170) History

With a long coastline and growing regional ambitions, China has built a large number of surface ships to control nearby waters in hopes of expanding its operations outward. In 2004, the Lanzhou ship (170) was officially launched, and the 052C-class guided missile destroyer was born. The ship was laid by Changxing Island-Jiangnan Shipyard in 2002 and launched on April 29, 2003. It officially entered service in July 2004 and is still an active patrol member of China's modern fleet in the South China Sea Fleet. Lanzhou is the lead ship of the Chinese Navy's 052C-class destroyer, and NATO recognizes it as the "Luyang II-class".

Her sisters include Haikou (171), Changchun (150), Zhengzhou (151), Jinan (152) and Xi'an (153).

Structurally, Lanzhou is traditional by modern standards, employing proven naval stealth measures such as closed pyramidal masts, flush hull/superstructure side walls, and shallow funnels. Except for the single-deck guns and turrets, the bow deck was mostly bare, with the missile bay directly aft of the guns. The superstructure contains a close-range defensive weapon and leads to the bridge - easily recognizable by its large window panes. Communications, sensors and radar systems are mounted on the bridge, which also includes a set back main mast. Pairs of chimneys are arranged side by side behind the mast structure.

This position is slightly forward or to the right amidships. A shorter enclosed mast is mounted aft of the smoke funnel, leading to a slightly elevated superstructure containing a full-service hangar.

The stern consists mainly of the helicopter reception/launch deck, one of which is carried by the ship.

Lanzhou displaces 7,000 tons under load and is powered by a CODOG (combined diesel or gas) system, allowing her form to propel itself under ideal conditions at 30 knots and output about 57,000 horsepower. The CODOG unit connects the geared gas turbines (2 x Ukrainian DN80 in this case) to the diesel engines (2 x German MTU Friedrichshafen 12V 1163TB83 series), the gas system is connected to the reduction gear and ends with the clutch.

The gas turbine provides the required high-speed envelope ("arrow"), while the diesel engine provides the required cruising speed. CODOG systems are less complex than their CODAG (combined diesel and natural gas) sibling systems, but they are more fuel-intensive.

Dimensionally, the Lanzhou is 154 meters long, 17 meters wide, and has a draft of 6 meters.

As a modern naval vessel, Lanzhou is equipped with various electronic processing systems. Their main kit is the Type 348 radar, a system of Ukrainian origin with a range of 450 km. Introduced in 2004, it is paired with the ship's most important HHQ-9 series of missiles.

This is followed by the Type 344 series of fire control radars, the LR66/TR47C system and the Type 364 short-range defense radar system.

Lanzhou destroyers are equipped with a range of weapons to deal with the threat at hand - air, surface or underwater. These include fixed-wing and rotary-wing threats, as well as cruise missiles, submarines and warships. Her primary armament consists of 42 HHQ-9 series surface-to-air missiles housed in six separate seven-shot vertical firing units forward of the bridge and behind the deck guns. The HHQ-9 is a medium- and long-range active radar-guided missile, developed and produced locally by CPMIEC and launched in 1997. She has a range of up to 200 kilometers, an altitude range of 98,425 feet, and a top speed of Mach 42.

The ship was also able to carry a pair of equipped quad launchers behind the second pylon. These products were launched in 2005 and are also produced locally.

Each missile carries a 300kg warhead and is powered by a turbojet with a range of 400km and speeds approaching Mach 1. The Deck Gun is a 100mm "dual purpose" mount designed to engage sea/land and air targets. It can support amphibious landing operations by engaging inland targets from offshore firing positions. The 2 x 730 30mm Close-In Weapon System (CIWS) provides close target engagement and is similar in form and function to the 20mm Phalanx Gatling-type digitally guided weapon system used on many U.S. Navy ships. The ship maintains anti-submarine measures by using 6 torpedo tubes.

Countermeasures include 4 x 18-tube decoy rocket launchers. The aft flight deck supports 1 x Kamov Ka-27 / Harbin Z-9C Anti-Submarine Warfare (ASW) or Search and Rescue (SAR) Naval Helicopter, which can be used in conjunction with onboard systems to locate, track and capture enemy submarines attacking warships.
