第一艘试验结束后立即开始073II型，第一艘以弦号904号进入中国海军服役，随后被命名为073I型，后来被命令完全改装为073II型标准。

 

The Type 073-class landing ship is a family of landing ships developed and operated by the People's Liberation Army Navy, it consists of several models. This article details the development of this class that begun in the 1960s. The most recent and modern model of the class is the Type 073A, which were built and commissioned in the 2000s.

073型登陆舰是中国人民解放军海军研制操作的一系列登陆舰，由多个型号组成。本文详细介绍了这个级别始于20世纪60年代的发展。该级别最新的现代化型号是073A型，于2000年建造并服役。

Requirement of the Type 073-class landing ship was finalized in May 1965, and design work by Shanghai-based 708th Research Institute completed just 4 months later in September 1965. Preparation to build this class was completed in October 1966, and construction begun a month later in November 1966. Due to political turmoil in China at the time, namely, Cultural Revolution, it was not until almost three years later in August 1969 when the ship was launched. From November 1969 thru December 1969, extensive trials were conducted and the ship was handed over to PLAN in December 1969 for further tests. In 1970 more tests were conducted with more than 7,000 km (3,800 nmi; 4,300 mi) logged, and the longest trip was from Chongqing to Dalian.

073级登陆舰的需求于1965年5月敲定，总部位于上海的第708研究所的设计工作仅在4个月后的1965年9月就完成了。建造该班的准备工作于1966年10月完成，一个月后于1966年11月开始建造。由于当时中国国内原因，即文革期间，直到近三年后的1969年8月，该舰才下水。从1969年11月到1969年12月，进行了广泛的试验，并于1969年12月份将该舰移交给中国人民解放军海军（PLAN）进行进一步的测试。1970年，进行了更多的测试，记录了7000多公里（3800海里；4300英里），最长的一次是从重庆到大连。

 

However, trials revealed that the vibration was too great at high speed, and the Type 073 did not enter production. Redesign work designated as Type 073II immediately started after the trials of the first unit ended, and the first unit entered PLAN service with pennant number 904 and was subsequently designated as Type 073I, and was later ordered to be fully converted to Type 073II standard. Due to the political turmoil at the time, conversion was not completed until 1975.

然而，试验表明，在高速时振动太大，073型没有进入正式建造。第一艘试验结束后立即开始073II型，第一艘以弦号904号进入中国海军服役，随后被命名为073I型，后来被命令完全改装为073II型标准。由于当时的政治动荡，改装直到1975年才完成。

Type 073II Yudao-class landing ship

073II型玉岛级登陆舰
 

 

Shortcomings of Type 073I exposed in trials caused a crush program to rework and redesign at Dalian Shipyard, but due to political turmoil in China at the time, it was not sufficient to correct the problem completely. Shipyard # 9308 in Anhui petitioned the 6th Machinery Industrial Ministry and Anhui provincial Defense Industrial Office to construct Type 73II LSM in 1975, which was approved in April 1976, with orders for 3 ships. Construction of the first Type 073II LSM at Shipyard # 9308 begun five months later in September 1976, and it was launched in June 1978. From 1978 to 1979, extensive trials were conducted and the ship was handed over to PLAN in early 1980, with pennant number East Transport 757 (East Transport = Dong Yun 东运 in Chinese), meaning Transport 757 of East Sea Fleet of PLAN. This unit was later reassigned as # 937.

在试验中暴露的073型的缺陷导致了大连造船厂的重新设计，但由于当时中国的政治动荡，这不足以完全纠正这个问题。1975年，安徽9308船厂向第六机械工业部和安徽省国防工业办公室请求建造73II型LSM，1976年4月批准，订购3艘。五个月后的1976年9月，在9308号造船厂开始建造第一艘073II型LSM，并于1978年6月下水。从1978年到1979年，进行了广泛的试验，船在1980年初移交给中国海军，弦号东运输757（中文东运输= Dong Yun东运），意思是中国海军东海舰队的运输757。这个单位后来被重新分配为第937号。三艘分别为（937[东运757] 938吕梁山[东运800] 东运801[南运745]）。

 

The primary difference between Type 073I and Type 073II is in the engine. Additional balance weight was added to the diesel engine which solved the vibration problem, but the reliability issue of the engine remain unsolved, and as a result, Type 073II did not enter mass production, just like its predecessor Type 073I.

073I型和073II型的主要区别在于发动机。柴油发动机增加了额外的配重，解决了振动问题，但发动机的可靠性问题仍未解决，因此，073II型没有像其前身073I型那样进入大规模生产。

Type 073IIY Yudao-class landing ship

073IY型玉岛级登陆舰

 

As the mass production plan for Type 073II was cancelled due to reliability problem of its engine, Shipyard # 9308 begun to modify the remaining two units that were already being built, which was successfully completed in September 1985. The resulting type is Type 073IIY-class landing ship, with Y for Yun (运), meaning transport in Chinese. Type 073I, Type 073II, and Type 073IIY all received the NATO reporting name Yudao-class. A total of two units of Type 073IIY were completed, with pennant #s 937 and 938. The primary difference between Type 073II and Type 073 IIY includes more than 100 upgrades in addition to engine improvement.

由于073II型的大规模生产计划因其发动机的可靠性问题而被取消，9308号造船厂开始对正在建造的剩余两艘进行改造，并于1985年9月成功完工。最终的型号是073IIY级登陆舰，Y代表运(运), 中文意思是运输。073I型、073II型和073IY型北约报告名称都为玉岛（Yudao）级。总共完成了两艘073IIY型，弦号分别为937和938。073II型和073IIY型的主要区别在于，除了发动机改进外，还包括100多项升级。

Type 073III Yudeng-class landing ship

073III型玉登级登陆舰
 

 

The reliability problem of the engine of Type 073 series was not completely solved until the appearance of Type 073III-class landing ship, with NATO reporting name Yudeng-class. The D-39 engine that is reliable only at slower speed was replaced by a new engine that is reliable at all speeds, and displacement is also increased. Only one unit entered service, with pennant # 990 in 1991.

073型系列发动机的可靠性问题直到073III级登陆舰出现才完全解决，北约报告称其为玉登级。D-39发动机只在低速时可靠，被一台在所有速度下都可靠的新发动机取代，排量也增加了。只有一艘在1991年服役，弦号为990。
