Type 635 hydrographic survey ship is a series of hydrographic survey ships developed by China for its People's Liberation Army Navy (PLAN). Type 635 series in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Ce (测), meaning survey in Chinese, because these ships are classified as survey ship. 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, pennant numbers may have changed due to the change of Chinese naval ships naming convention. ==Type 635A/B/C== Type 635 A/B/C series with NATO reporting name Yanlai (延来) class is the first batch of the Type 635 series. These ships are sometimes collectively known as Type 635I, because the difference between these models are relatively minor in comparison to the second batch. These ships differ from second batch in that the deck at the stern is circular shaped and they are purely for surveying missions. Construction of the first ship begun in 1970 and some modification was made to the second ship, which was designated as Type 635B, and the first ship was subsequently designated as Type 635A. In 1976, based on the experienced gained from deployment, PLAN required further upgrade of Type 635B and these ships are designated as Type 635C. Design was completed in Jun 1977 and construction for both ships begun simultaneously in October of the same year, and they entered service respectively in 1982 and 1983. Type 635C actually developed later than Type 635II, and they are built by Jiangxi Ruichang Jiangzhou Shipyard (江西瑞昌江州造船厂), a division of (Jiangzhou Union Shipbuilding Co., Ltd. (江西江州联合造船有限责任公司) ) Specification:〔(【引用サイトリンク】 title=Type 635 )〕 *Length (m): 74.8 *Length between perpendiculars (m): 68.6 *Beam: 10 *Depth (m): 4.7 *Draft (m): 3.5 *Displacement (t): 1216 *Main propulsion: two diesel engine @ 1320 kW (1800 hp) each *Max wind scale allowed for sailing: 10 *Range (nm): 4000 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Type 635 hydrographic survey ship」の詳細全文を読む スポンサード リンク
