Type 035 Ming-class Submarine

The Type 035 Ming-class submarine is a class of diesel-electric submarines of the People's Liberation Army Navy. The Type 035 is a heavily improved redesign of the older Type 033 Romeo-class submarines, which were built in China from 1962 to 1984.

Variants

 * Type 035: First unit of the Ming-class submarine, with construction of two units begun simultaneously in October 1969 in Wuchang Shipyard and Jiangnan Shipyard. The general designer was Wei Xumin (魏绪民). The most significant difference between Type 035 Ming class and Type 033 Wuhan class is that the former is driven by a single shaft instead of twin shafts of the latter. Trials completed in October 1974 and this first unit (original pennant number 162, but later changed to 232) built at Jiangnan Shipyard entered Chinese service in the following month.
 * Type 035A: The second unit of the Ming-class submarine with pennant number 342 was built at Wuchang Shipyard, and many problems were discovered during its trials. As a result, the Chinese navy ordered 701st Institute to perform a major redesign, which not only solved the problem, but also increased the top speed by 40% to 18.3 knots (33.9 km/h; 21.1 mph). The redesigned boat was completed in June 1980, and finally entered Chinese service on December 24, 1982, with a new designation of Type 035A. In December 1983, the decision was made to stop the production of a new Type 033-class boat and replace it with a Type 035A. After the completion of the first Type 035A in 1982, the production of Type 035 briefly halted, until 1987, when the production restarted again and 3 more units were completed before the production ended in 1990.
 * ES5C: Export version of Type 035/035A, with updated fire control system to launch acoustic homing torpedoes. There is no known export, but the design was used to upgrade Type 035/035A fleet.
 * ES5D: Further development of ES5C for export, with capability to launch anti-ship missiles while submerged added. As with its predecessor ES5C, there is no known export but the design was used to upgrade Type 035/035A fleet.
 * Type 035G: Program begun in 1985, and the first unit with pennant number 356 was launched in 1989, entering service in December 1990, and state certification received in 1993. This is the first Type 035 series to have anti-submarine (ASW) capability. The primary weaponry for Type 035G is Yu-3 torpedo, and French sonar DUUX-5 and its Chinese-built version were used on later units, 12 of which were completed between 1990 and 1999. The last unit with pennant number 308 was lengthened by 2 meters (6 ft 7 in) to add a section for AIP tests.
 * ES5E: Export version developed from Type 035G, with ability to launch wire-guided torpedoes added, but there is no known export.
 * Type 035ET: French sonar system and its equivalent Chinese version on ES5E export version of Ming was expensive, so a cheaper alternative was developed, using Italian sonar systems, the JP-64 active sonar and Velox passive sonar of the Toti-class submarine. However, this failed to attract any buyers and the unit went into Chinese service instead.
 * ES5F: Export version with integrated sonar system that integrates previously separated active, passive ranging, flank (and towed upon customer's request) sonar into one.
 * Type 035B: First batch of four completed between 2000 through 2003, and additional order followed sometimes later. Conning tower and certain portion of hull was redesigned, with new structure similar to that of Type 039 submarine. This type was capable of launching land attack cruise missiles from torpedo tubes.
