As reported by the magazine "Jane's Defense Weekly" in an article by Richard D. Fisher Jr. "Modification to sail of Qing-class" with reference to the photo appeared in the Chinese Internet, the Chinese experimental diesel-electric submarine project 032 (on-board number "201") underwent a conversion, presumably for testing A new type of ballistic missile. At the photo taken in July 2017 of this submarine at the Dalian Liaonan Shipyard shipyard in Dalian (more precisely, in Lushun - the former Port Arthur - now part of Dalian), it is noticeable that in the rear part of the railing of the drawers of the boat A missile mine of a greater length than before was clearly installed, which is now seriously "issued" in height.
According to speculation, the modernization of the boat was carried out to carry out marine tests of the prospective marine ballistic missile JL-3, allegedly created for future Chinese nuclear missile submarines of the new generation of the project 096. About the development of the Chinese atomic missile submarine project 096 and the ballistic missile JL-3 for It is reported in the latest report of the "China Military Power" of the US Department of Defense.
On the bmpd side, recall that the Chinese experimental prototype diesel-electric submarine project 032 (Western designation type Qing, the Chinese side number "201", the name "Great Wall 201") is considered the world's largest non-nuclear submarine, having a full underwater displacement of more than 6600 Tons and a length of 92.6 meters (our blog has already reported about it - here and here). The boat was built in Wuhan by the shipbuilding company Wuchan Shipbuilding company Wuchang Shipbuilding Industry Company, a part of China State Shipbuilding Corporation China Shipbuilding Industry Corporation (CSIC). Construction of this submarine was started in Wuhan in 2008, launching took place in September 2010, and during 2011-2012 the boat was tested. On October 16, 2012, the boat officially became a member of the PLA Navy.
The project 032 boat was designed and built to replace the PLA Navy used since 1965 as an experimental diesel-electric missile submarine of the Soviet project 629 (the Chinese designation project 031, the on-board number "200", was assembled in Dalian from the structures supplied from the USSR) and Is designed to develop various types of underwater weapons, including rocket, as well as detection systems, including the SAS. The general design of the double-hull design of Project 032 replicates Project 629 with the deployment of two ballistic missile silos. Passing through the hull of the boat and the fence of retractable devices. At the same time, the contours of the light hull of the 032 project boat were apparently largely borrowed from the Soviet submarines of projects 877 and 636. The project 032 also installed four vertical launching installations for cruise missiles, two 533 mm torpedo tubes and reserved seats for the new Special equipment. The boat is also for the first time in the underwater shipbuilding of China, equipped with a life-saving pop-up camera modeled on Soviet and Russian nuclear submarines.
Initially, two JL-2 ballistic missiles were installed on the 032 project's boat, however, according to Chinese publications, the boat was "late" by construction and in fact was no longer used for marine testing of this missile, which now forms the main armament of the 094 project SSBN in China.
