Thailand has selected the S20 sub for their 10-year Navy procurement plan:

The following passage might interest some PLA watchers:



The "other competitors" included Russia, France, Sweden, ROK, and Germany, although I think only the latter two were shortlisted.
could maintenance & close proximity to china be a factor too?

The S20 is the export version of the Yuan class I believe. They will be good subs for Thailand.

In their surface fleet, Thailand has a total of nine major surface vessels from China.

Six are Chinese frigates. Four Type 053HT class vessels and two Type 025T, Naresuan class vessels. They displace 2,000 tons and about 3,000 tons respectively. The 053HT were delivered in the early 1990s and have Chinese engines, sensors and weapons. But back then (realizing this was almost 25 years ago), Thailand had some real issues with the vessels and the negative feedback drove China Shipbuilding to improvements. Ultimately Thailand added the two Naresuan class vessels which were improved and larger versions of the Type 053 frigate hull form. These were commisisoned in 1994 and 1995, but Thailand ordered and installed western engines, sensors and weapons on them.

Those two are quite good vessels and are each less than ten years old. Here's how they look:

Clearly a very western style, but also an interesting concept. Chinese hull and structure, western engines, sensors and weapons.

The Thai Navy also has two Offshore Patrol Vessels that were designed in Thailand, but built in China. They are the HTMS Pattani (OPV 511) and the HTMS Narathiwat (OPV 512). The first was delivered to Thailand and commissioned in 2005. The second followed and they displace 1,450 tons and also are fitted with western weapons and sensors. They are vey nice, modern vessels too.

Finally, Thailand also has a replenishment ship, the HTMS Similan, which is a Chinese built Type 908, Fusu class vessel. China has one that was purchased unfinished from Ukraine in 1993, the former Vladimir Peregudov, which in Chinese service is named the Qinghaihu. China then built another one for the Thai Navy, the HTMS Similan which went into service in September 1996.

So, the Thai Navy is used to operating with Chinese equipment. Some of it completely Chinese, others adding western sensors, weapons, and even engines.

Apparently with these subs they are planning on an all Chinese fit.

The S-20 is larger than the Type 209 and Type 214, so it might have longer endurance?
And China is probably a lot more willing to integrate in things like cruise missiles and underwater unmanned vehicles.

Also S20 (~Yuan) is a double hulled, so naturally is larger

I believe this is the first Chinese subs export since Ming/Romeo in 1980s (?).

S20 seems very good sub, perhaps not as good as Yuan, but should be very close. Is there any statement whether this version of subs would be fitted with AIP ?

Exclusive: Chinese submarine lurked past Indian waters, docked in Karachi?

According to reports, China's Yuan Class 335 submarine crossed the Arabian Sea and entered Karachi port on May 22.

In the already turbulent conditions over the Arabian Sea, this is by far the most alarming incident in recent years. The Indian Navy had a big alert last month when

According to reports, on March 31 this year, China's deadliest conventional submarine set sail from its base on Hainan island in the South China Sea. The Yuan-class submarine '335', equipped with torpedoes, anti-ship missiles and an air-independent pro-pulsion that dramatically enhances its underwater endurance, entered the Gulf of Aden over a fortnight later. But it was 335's first port of call that caught the attention of the security establishment in South Block

No Yuan homeported in the Hainan, in stopover.

Odd to see this called an "incident". The boat could have docked in Mumbai if invited to do so.
