Type 917 torpedo retriever (TR/TWR) / range support vessel / target ship (AGT ) is a type of little known auxiliary ship built in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN). [1] [2] [3] [4] [5] As a successor of earlier Type 803 torpedo retriever, Type 917 TR/TWR/AGT has received NATO reporting name Damen class, [1] [2] [3] [4] or 大门 in Chinese, meaning "big gate". As with its predecessors, once these have retired from their original torpedo retrieving duties, they are converted to range support vessels/target ships, [6] until finally sunk as targets. Specification: [1] [2] [3] [4] [5]

Type 917 AGT/TWR/TR in PLAN service is designated by a combination of two Chinese characters followed by a three-digit number. The second Chinese character is Yun (运), meaning "transport" in Chinese, indicating that in addition to range support and targeting missions, this class is also used as transports (AP), though some modification work is required to remove onboard range support and targeting equipment before it can be used to transport cargoes. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet. However, the pennant numbers are subject to change due to changes of Chinese naval ships naming convention, or when units are transferred to different fleets. As of 2022, a total of nine ships have been identified: [1] [2] [3] [4]

Dubei class target ship (AGT) and range supporting vessel is a very little known auxiliary ship of the People's Liberation Army Navy (PLAN),and has received the NATO reporting name Dubei class.Originally built as a SWATH test platform,it was subsequently converted to a target ship by adding radar reflectors and other electronic equipment to simulate various targets in support of anti-ship weaponry development, but is still capable of housing different scientific instruments to perform various research tasks, and thus also acts as general purpose research ship (AGE).

Type 912 degaussing/deperming ship (ADG) is a type of little known auxiliary ships built in the Republic of China (PRC) for the People's Liberation Army Navy (PLAN), and this class has several derivatives. As of 2022, Type 912 is the most numerous degaussing/deperming ship in PLAN, and the longest serving degaussing/deperming ships in PLAN, until its successor ype 911 finally begun to appear in early 2010s.

The Dulaji class are a class of environmental research ships (AGER) currently in service with the People's Liberation Army Navy (PLAN), and the design is also modified for cable layer (YRC) in PLAN service, with both versions have received the same NATO reporting name Dulaji class because they share the same hull. The exact type of this class remain unknown as of 2022, because no official information has been released, despite the ships have already been in service for more than a decade. In addition to the usual task of conducting regular environmental sampling, monitoring/surveillance and research missions, these ships are also tasked with additional task of sewer transfer and treatment from other ships to prevent sewer onboard other ships from overflowing into the sea and thus causing pollution, and thus these ships also act as sewer vessels for vessel sewage discharging.

Sea trials begun on May 11, 1963 and the first unit was finally handed over to PLAN on December 24, 1963at Lüshun.However, delivery of subsequent units have been delayed due to political turmoil in China at the time, namely, the Cultural Revolution, so it was not until 1977, when the originally planned total of six units had finally been completed, including two foreign sales, one for Tanzania, and another for Cambodia.Specification:

United States Navy torpedo retrievers

United States Navy submarines, surface ships, and aircraft launch torpedoes, missiles, and autonomous undersea vehicles as part of training exercises. Typically, these training munitions have no warhead and are recovered from the sea and reused. Similarly, new naval weapons under development are launched at sea in performance trials. These experimental units also need to be recovered, in their case to obtain evaluation data. At various points in history, newly manufactured torpedoes were fired as a quality control measure and these, too, had to be recovered before issuing them to the fleet. The U.S. Navy has used a variety of boats to accomplish the retrieval of these test and training munitions. As their missions evolved over the last century they have been variously known as torpedo retrievers, torpedo weapon retrievers, torpedo recovery boats, range support craft, and multi-purpose craft.
