Yuzhao Class landing platform dock (LPD) Type 071

Type 071 landing platform dock (LPD) is a new class of amphibious warfare vessels built by Hudong-Zhonghua Shipbuilding, a subsidiary of China State Shipbuilding Corporation (CSSC), for the People’s Liberation Army Navy (PLAN).

The Type 071 LPD is primarily deployed in amphibious landing missions and can also conduct humanitarian aid and civilian evacuation missions.

The first LPD in the series, Kunlun Shan (998), was launched in December 2006 and commissioned in November 2007. Jinggang Shan (999), the second vessel in the series, was floated out in November 2010 and was inducted into service in October 2011.

The third ship in class, Changbai Shan (989), was launched in September 2011 and entered service with the PLAN in September 2012. Yimeng Shan (988) was launched in January 2015 and commissioned in February 2016.

A modified variant of the Type 071 LPD was offered by the China State Shipbuilding & Trading Corp (CSTC) consortium for the Royal Malaysian Navy.

Type 071 LPD design and features

Type 071 LPD ships feature a unique hull platform offering a large dock space. The ship also offers a dedicated space for medical care and is equipped with a fresh water supply system. The stabilisers fitted to the vessel reduce roll and improve the stability in high sea states.

The high volumes of internal space support the installation of additional communications systems, which make the ship a fleet command and control centre during amphibious operations.

The Type 071 LPD has a length of 210m, beam of 28m and a draft of 7m. The full load displacement of the vessel is 25,000t.

Cargo housing capacities

The amphibious warfare ship features a vehicle deck, well-deck, landing deck and a hanger. It can carry a combination of marines, vehicles, landing craft and helicopters.

The vehicle deck can house amphibious assault vehicles including ZBD05 amphibious IFV, and ZTD-05 amphibious assault tracked armoured vehicle. The stern ramp, two side doors and ramps allow rapid loading of the vehicles and equipment.

The well deck houses up to four landing craft air-cushioned (LCAC), which can transfer vehicles or marines to the shore at high speed. The LCAC are launched by flooding of the docking area. The vessel can also carry landing craft on port / starboard davits.

They are assigned to a landing ship flotilla of the South China Sea Fleet of the PLA Navy. (81.cn/ Gan Jun) – chinamil.com.cn

Type 726 Yuyi class landing craft, air cushion (LCAC)

In conjunction witht the building of Red China’s first LPD, the Type 071, Yuzhao Class LPD, the PLAN also embarked on designing and building their own landing craft, air cushion (LCAC) to go with it.

In 2008, a new, indegenous Chinese LCAC was observed. It is remarkably similar to the US LCAC, except the control house is on the port side of the vessel instead of the starboard side. In addition, the Chinese LCAC apppears a little smaller than the American LCAC.

These vessels appear to have four gas turbines to power them. It is not known whether those turbines are indigenous Chinese designs or based on Russian or Ukrainian technology

By 2010 as many as four had been observed, but it is anticapted that more are building since the PLAN launched a second Yuzhao class LPD in 2010 and will likely launch a third in 2011. Since each LPD is supposedly capcable of carrying 3-4 LCACs it is anticpated that 10-12 will be built as a minimum. More if more LPDs are built, and even more if the anticpated PLAN LHD Class Amphibious Assault ship is constructed.

The specifications include:

Qty: 4 (more building)
Length: unknown
Beam: unknown
Displace (Full): unknown
Propulsion:
– 4 gas turbines, 2 fans
Speed: 40 knots (est)
Crew: 4-5 est.

Type 364 G-band air search radar

The Type 364 radar was developed by the Yangzhou Marine Electronic Instruments Research Institute (扬州船用电子仪器研究所) / No. 723 Research Institute. It is typically enclosed in a dome on new PLA-N‘s frigates and destroyers.

An improved version of the earlier Type 360, it replaces the Yagi IFF antenna with a planar IFF configuration and moves to higher frequencies in order to achieve better target discrimination. The dome is also expected to improve azimuth resolution.

It is expected to be used primarily for CIWS (Type 730Type 630) targeting with secondary air search and SSM targeting abilities.

It is offered for sale through the China Shipbuilding Industry Corporation (CSIC).
