I guess they are more self confidence with their product and willing to show more of their line up
Interesting is their proposal for mono hull sub probably reflecting advance in design and metallurgy in recent year
Henri K take on the new export submarine as shown in Bangkok naval trade show

, the Chinese naval group CSIC continues to push its pawns and expand its offerings for this segment of the global arms market that is both geo-politically sensitive and above all very lucrative.

It is through its subsidiary China Shipbuilding Company and Offshore International Company (CSOC) that the Chinese state group unveiled, during the Defense & Security 2017 exhibition which took place from November 6 to 9 in Bangkok, its three new -marines entirely dedicated to the export.

And it's not three totally different products to each other, but a new family of conventional submarines ranging from 200 tons for the smallest and up to 1,100 tons for the largest, to be able to address varied operational needs and portfolios of different sizes of potential clients.

Except for the smaller model called MS200, CSIC now offers a range of Air Independent Propulsion (AIP) vectors on the market today. According to a video presentation of the Chinese group, several countries have already shown interest, among which include the name of Algeria, Cuba, Egypt, Libya, Burma, Saudi Arabia, the United Arab Emirates and Venezuela.

partners show that the Chinese industrialist finally leaves out their "love" for double-hull submarines, a long-standing legacy from the Soviet era, and returns to the mono-hull design. On the other hand, this shows the progress made in recent years by the country in terms of materials and a set of associated technologies.

The massif of these three new Chinese submarines also seems to have benefited from the latest research in hydrodynamics and acoustics of the Institut 701, CSIC group's main research bureau on surface and submarine off-nuclear vessels, and is taking over the trapezoidal shape already observed on the new ships of the last batch of Chinese Navy Type 039B attack diesel submarine.

This further reduces noise underwater and thus improves the survivability of buildings. Aligned purges, as on some of the new submarines such as the Japanese Navy's Sōryū class, also show the constant effort of the Chinese to reduce the acoustic level of their vessels underwater.

On the other hand, this new range of Chinese submarines has still not adopted X-shaped bars (in Saint Andrew's cross), which lead to better effect in navigation, nor pump-propeller which is quieter compared to the propellers. conventional, while research papers and published material suggested that new Chinese buildings of the new generation should

A former Chinese naval technical officer also pointed out that Chinese manufacturers are becoming not only more transparent in the performance of their products, but also much more confident in their dealings with prospects and competitors. He also said that the data are almost identical, in some respects, between the S26T for Thailand and the Type 039B used by the Chinese Navy.

But the transparency of CSIC could perhaps be explained by the imminent arrival, if not already done, of a new class of Chinese AIP submarine Type 039C , which would be "much more advanced" than its predecessor Type 039B still according to the same source of the Chinese navy. A habit that has been observed for a long time among the Chinese who allow themselves to reveal the products of an older generation when a new is on the way.

Apart from submarines whose design and performance are close to those of other traditional marine powers, the Chinese industry is also working on its level of services to better compete with the usual players in this market, namely Russia, France, Germany, Japan and South Korea.

In addition to longer-term warranties on building maintenance and availability of spare parts, as well as a comprehensive package to train customer submariners by the Chinese Navy, CSIC also offers to help their customers build ground infrastructure to support the activities of submarines, as Thailand might do if we believe in some local sources.

For customers with a lower budget or lower operational requirements, older submarines removed from active duty by the Chinese Navy and retrofitted are another possible solution. The Bangladeshi Navy, for example, received two Type 035G class submarines in November 2016 for a mere $ 200 million.

do you know what kind of improvements of Type 039C over 039B ?

Good to see Henri is consulting pop3's recent writeup on the Yuan and S26T.

One of the multiple forums pop3 posted to is

, translation of main points below;

  • Released specifications of S26T are almost identical to 039B's
    • S26T's normal displacement is 2550t, 039B is 2570t
    • S26T's length is 77.7m, 039B is 77m
    • S26T's width is 8.6m, 039B identical
    • S26T's hull height 9.2m, 039B identical
  • 039B's pressure hull is 67.2m long
  • 039B construction consists of continuously-casted 921A and 980 steel, assembled using Hull Block Construction Method
    • Yield strength of 921A is 590-745MPa, of 980, >785MPa
  • CSIC 711th Institute was responsible for development of Stirling AIP system
  • 039B hull divided into six compartments, I - VI
    • I is the weapons and fore battery compartment
    • II is the command compartment
    • III is the living quarters and aft battery compartment
    • IV is the diesel engine and generator compartment
    • V is the AIP compartment
    • VI is the shaft machinery and driving motor compartment
  • 039B is equipped with Type 265 sonar array and Type 205 sonar, and is able to fire decoys
  • The willingness of the PLAN to allow export of S26T with an overall design almost identical to 039B implies the completion of the 039C project initiated some years back
  • 6-7 years ago, the PLAN considered importing the Russian Amur-class but nothing came of it and it's unlikely the deal is still on
  • Small-scale nuclear propulsion has been under development for some years

Pardon me for my ignorance. The Stirling engine AIP system still require liquid oxygen tank? It'll be interesting to know the speed under AIP engine.

Look like another Yuan class submarine on the upper right corner. Which one is it? It isn't easy to keep the count of the Yuan class subs on track.
It is very difficulf for submarine but i watch regurlalrly
No new 2 there ( 10 /2017 ) and 3 or 4 to Wuhan 1st soon in service appear on a pic in sea trials some month ago plus 13 in service last N° 342 in service since 2015.
Ramping up production to replace Ming for about 2020 a surge don' t means each year this number explained an a article in Sina but for fing the link ! they have yet build 2 by year even more Song 3 some years in average 2
