    向阳红(Xiangyanghong) 10

    向阳红 10号是在1970年后期建造的一艘海洋调查/通信船去支援中国第一个全射程洲际弹道导弹(ICBM)测试计划(718计划)。最初计划三艘设计包括一艘海洋调查船,一艘气象船,和一艘通信船,但是它们用一艘船代替去节省成本。643型船的设计在1971年2月开始,而且开始建造在1975年7月第一艘船体向阳红 10号下水。船在1979年10月正式地被交付。

    643型为多种任务而设计的一艘多功能船,包括:

    海洋调查用于导弹测试的目标范围
    天气预报;和气象、水文支援
    重力和地磁测量用于导弹弹道修正
    远程通信支援和中继
    水下声学数据收集去支援重获再-入运载器
    不仅标准的海洋调查设备,643型也装备多种的专用设备,包括:

    直升飞机机库和飞行甲板容纳一架Z-8(SA-321Ja 超级大黄蜂)直升飞机
    气象中心用于天气预报
    全天候远程通信系统
    高功率海洋声学系统
    深-海水下运载器
    643型共用925型(北约代号命名:Dajiang级)海上救援和防险救生船的相同船体设计,保留上部构造之前位于舰艏甲板上的大型起重机。

    在它被改装之前,向阳红 10号已经被国家海洋局(SOA)东海分局操作。

    远望(Yuanwang) 4

    在1998年,向阳红 10号改装成一艘航天跟踪船去支援中国有人操纵空间计划(921计划), 而且被重新命名为远望 4号。在舰艏甲板上的大型起重机和通信天线桅杆移除被一座跟踪雷达代替。

    不像其它的远望航天跟踪船,远望 4号缺乏能力控制航天器,并且服务主要用于航天器跟踪和通信中继角色。船只通常位置在南太平洋在一次任务航行期间去转播神舟飞船和在北京的任务控制中心之间的视频和音频通信信号。2005年,远望 4号承担9个任务覆盖总航程120,000海里。

    退役

    远望 4号在2007年中期一次火灾事故中严重损害,并且已经随后退役。

Type 643 Multi-Purpose Oceanographic Survey Ship

Xiangyanghong 10

Xiangyanghong 10 was an oceanographic survey/communications ship constructed in the late 1970s to support China’s first full-range ICBM test programme (Project 718). Three designs including an oceanographic survey ship, a meteorology ship, and a communications ship were originally planned, but they were replaced by a single ship to save the costs. Design of the Type 643 ship began in February 1971, and the construction began of the first hull Xiangyanghong 10 in July 1975. The ship was officially delivered in October 1979.

Type 643 is a multi-functional ship designed for a range of tasks, including:

  • Oceanographic survey for the target zone of the missile test
  • Weather forecasting; and meteorological and hydrological support
  • Gravity and magnetic survey for missile ballistic correction
  • Long-range communications support and relay
  • Underwater acoustical data collection to support the recovery of the re-entry vehicle

As well as the standard oceanographic survey equipments, Type 643 was also equipped with a range of special equipments, including

  • Helicopter hanger and flight deck to accommodate a Z-8 (Sa 321Ja Super Frelon) helicopter
  • Meteorological Centre for weather forecasting
  • All-weather long-range communication system
  • High-power ocean acoustic system
  • Deep-ocean underwater vehicle

Type 643 shares that same hull design of the Type 925 (NATO codename: Dajiang class) ocean salvage and rescue ship, retaining the large crane located on the bow deck in front of the superstructure.

Xiangyanghong 10 had been operated by the East Sea Branch of the State Oceanic Administration (SOA) before it was converted.

Yuanwang 4

In 1998, Xiangyanghong10 was converted into a space tracking ship to support China’s manned space programme (Project 921), and was renamed Yuanwang 4. The large crane and communication mast on the bow deck was removed and replaced by a tracking radar.

Unlike other Yuanwang space tracking ships, Yuanwang 4 lacks the ability to control the spacecraft, and serves mainly for spacecraft tracking and communications relay roles. The ship is normally positioned in the South Pacific Ocean during a flight mission to rebroadcast the video and audio communications signals between the ShenZhou spacecraft and the mission control centre in Beijing. By 2005, Yuanwang 4 had undertaken 9 missions covering a total distance of 120,000 nautical miles.

Decommission

Yuanwang 4 was seriously damaged in a collusion and fire accident in mid-2007, and has been subsequently withdrawn from service.
