The Type 925 (NATO codename: Dajiang class) is the ocean salvage & rescue ship built in the early 1970s to support China’s first full-range intercontinental ballistic missile (ICBM) test. Under the Project 718 shipbuilding programme, Shanghai-based Jiangnan Shipyard was requested to build three different types of ships, including two Yuanwang class missile/spacecraft tracking ships, a Type 643 multi-purpose oceanographic survey ship (Xiangyanghong 10), and two Type 925 ocean salvage & rescue ships.

925型(北约代号:大江级)是在1970年早期建造的海洋打捞&救生船去支援中国的第一次全射程洲际弹道导弹(ICBM)测试。在718造船计划之下,上海建立的江南造船厂被请求建造三艘不同类型的船,包括二艘远望级导弹/航天飞船测量船,一艘643型多用途海洋调查船(向阳红 10号)和二艘925型海洋打捞&救生船。

The Type 925 is a large multi-purpose salvage & rescue ship capable of operating in deep oceans far from its base. The ship can serve both as submarine tender and salvage/rescue ship. The ship carries 1~2 deep submergence rescue vehicles (DSRV), handled by the large crane located on the bow deck. It was also the first PLA Navy ship to be fitted with helicopter hanger and flight deck as standard, capable of accommodating two Z-8/SA 321Ja Super Frelon helicopters.

925型是一种大型多用途海洋打捞&救生船有能力在深海中远离它的基地操作。船能作为潜艇供应船和打捞&救生船两者角色。携带1~2具深潜救助艇(DSRV),由位于艏甲板上的大起重机操作。它也是PLA海军第一艘配备有直升飞机机库和飞行甲板看作为标准的船,能够容纳二架Z-8/SA 321Ja“超黄蜂”直升飞机。

Two hulls (J302 and J121) were initially constructed in the late 1970s. J121 Changxingdao was assigned to the North Sea Fleet, and J302 Chongmingdao was assigned to the East Sea Fleet. Both ships took part in the Chinese naval task force to the South Pacific to recover the re-entry vehicle of China’s first full-range DF-5 ICBM test in May 1980. In November 1984, J121 Changxingdao participated another expedition mission along with Xiangyanghong 10 to send Chinese scientists to Antarctica to establish China’s first research station there.

二艘船(J302号和J121号)开始在1970年后期内建造。J121“长兴岛”号被分配给北海舰队和J302“崇明岛”号被分配给东海舰队。在1980年5月两艘船参加中国海军特遣部到南太平洋去回收中国第一次全射程DF-5 ICBM测试的再入运载具。在1984年11月,J121“长兴岛”号连同向阳红 10号一起参加另外的一个远征任务运送中国科学家到南极洲建立中国第一个研究站。

The third hull J506 Yongxingdao was commissioned by the South Sea Fleet possibly in the mid-1980s. The ship differs to the previous two hulls in that it has a large mast on the bow deck and a large sphere radome on the rear mast, both used to mount electronic equipments for unknown purpose. The ship was part of the naval rescue task forces standing by in the West Pacific during the launches of China’s Shenzhou manned spaceflight mission in 2003 and 2005.

第三艘J506“永兴岛”号在1980年中期可能进入南海舰队服役。船与先前的二艘船体不同,它在艏甲板上有一个大型桅杆和在后桅杆上有一个大球体形天线罩,两者用于去安装未知用途的电子设备。船是海军援救特遣部队的一部分在2003年和2005年中国发射神舟有人操纵航天任务期间在西太平洋上支援。

“大江”级潜艇救援舰,这是我国海军排水量最大、设备最齐备的潜艇救援舰艇。首舰一九七六年服役,共有3艘在役。其主要使命包括:救援失事潜艇与遇难的水面舰艇、深水救生和科研保障,配备有两部高频声纳、救生潜艇、潜水救生钟、减压舱、压缩空气系统和氦氮氧系统。该级舰也配备有长距离通讯设备和直升机起降平台,可作为科学考察船使用。在执行潜艇援救任务方面,对于在一定水深下由于故障而失去动力的潜艇,该舰可以以深潜救援艇、救生钟营救失事潜艇人员;可向失事潜艇提供高压空气,以排出潜艇的压载水使其上浮;必要时,还能打捞失事潜艇。自服役以来,该级舰多次参加了包括南极科学考察、潜艇水下发射运载火箭在内的重大科研、军事和救助行动。

“大江”级还首次配备了我国自主研制的国产新型深潜救生艇,该艇于1986年进行首次海试。这型深潜救生艇长15米,排水量35吨,最大下潜深度600米,可容纳4名艇员。每次对口救生人数为22人;在水下220米内可以开舱湿救6名人员。因艇上新设备了电视声成像声纳、定位声纳以及机械手等设备,所以它还能兼顾海洋调查和海底勘探等任务。该艇还装有水下摄像机、高频主动声纳和一个机械手。目前我国正在研制更为先进的动力定位系统以应用于最新国产深潜救生艇,它可以通过动力装置保持多个方向的定位,在海深流急、海水混浊、艇位不正的情况下也能够迅速与目标对接,也就是说,在失事潜艇呈较大倾斜角度的情况下,也能迅速与其对接实施救援。
