Type 271I landing craft utility
The origin of Type 271 series landing craft dates back in 1966, when World War II era LCU 1600 series PLAN captured from ROCN at the end of Chinese Civil War begun to be retired from service. PLAN proposed to develop a landing craft utility (LCU) based on the experienced gained from Type 067 utility landing craft and Type 068/069 mechanized landing craft (LCM). In addition to wartime mission, this class is tasked to supply islands without port facilities with up to 100 tons of equipment, cargo and freshwater in peacetime. The LCU is designated Type 271, and received NATO reporting name Yupen class, a name used for the rest members of Type 271 LCU series.
Design of Type 271 was completed in December 1967, after which the construction of Type 271 LCU begun in August 1968 at Qingdao Shipyard in Qingdao, and the boat was completed in June 1970. Sea trials begun in September 1970 in Qingdao, but the results were rather unsatisfactory. Based on these result, redesign work begun immediately with designation as Type 271II, and the unit already built was consequently named as Type 271I, and later converted to later standard, The primary reason for such disappointing result was because the political turmoil in China at the time, namely, the Cultural Revolution. Rework immediately begun and the modified model was designated as Type 271II, with the original Type 271 was redesignated as Type 271I for clear distinction. Type 271 is mainly intended for delivery of troop and vehicle in places along the rivers and coast without harbor facilities.
Type 271II landing craft utility
Type 271II landing craft utility is the direct result of the disappointing performance of the original Type 271 LCU. Redesign work of Type 271II LCU was completed in 1971, and construction begun in December 1972 at Qingdao Shipyard. In September 1975, the ship was launched and on November 30, 1975, this first unit of Type 271III LCU was handed to PLAN and begun trials. As with Type 271I LCU, the program was delayed due to the Cultural Revolution. The pace of trials and testing really picked up in 1976 when the Cultural Revolution ended, and this class finally received certification in 1978 and series production soon started after. The cargo capacity of Type 271II is either 3 Type 59 tanks or 7 5-ton trucks.
Type 271IID landing craft utility
As with the first member of Type 271 series LCU, Type 271II LCU was not produced in large numbers either, because in 1979, PLAN requested minor modification of Type 271II LCU based on experience gained from deployment. The result was Type 271IID LCU, with D stands for Dingxing (定型 in Chinese), meaning finalized design. The displacement is slightly increased to 507 t from the original 500 t of Type 217II LCU. The first unit of Type 271IID LCU was completed by Changsha Shipyard, and all earlier units were subsequently converted to this standard as Type 271IID went into series production at both Changsha and Qingdao. The modification included the pressure wave plate, anchor and propulsion systems.
Type 271III landing craft utility
In November 1984, requirement of Type 271III LCU was issued, but once again, the program was delayed, but this time was not due to political turmoil in China, but instead, the policy change: the economic reform in China had put military program in the backseat. As a result, construction of the first unit did not begin until March 1987 at Changsha Shipyard, and two years later in December 1989, the unit went into service. The primary improvement of Type 271III LCU over Type 271IID is that its propulsion system was German origin (MAN SE), and China license produced it to greatly increase the reliability and service life of engine. The armament and ability to operate in harsh sea state is also improved, while the bow door is changed to V-shaped double door from the original single piece flat piece.
Type 271IIIA landing ship medium
Type 271IIIA landing ship medium (LSM) is the latest member of Type 271 series LCU, and it received NATO reporting name Yulü class. The main difference between Type 271IIIA and Type 271III from which Type 271IIIA is developed from is that the displacement of Type 271IIIA when fully loaded has increased by a third to 800 tons, and hence becoming a LSM. Armament was greatly reduced to two Type 69 twin 14.5 mm MG, while speed is also reduced to 15 kt. The number of crew is almost doubled to 56 due to the need to handle more complex machinery. To accommodate the larger size, a pair of more powerful version of Chinese license produced MAN SE 8L20/27 diesel engine have been installed, each with 1142 hp. Typical cargo carrying capacity of Type 271IIIA is either 3 medium tanks plus an infantry platoon of 70 troops, or 7 light amphibious tanks (over load, usually 6 for normal payload), or 200 fully equipped troops.
