S26T program

The Royal Thai Navy (RTN) formally selected China's Yuan-class (Type 041) platform to meet a requirement for three submarines on 2 July 2015. The RTN's procurement committee voted unanimously in favour of purchasing the submarine, which has been designated S26T (Thailand), a modified export version of the Yuan class.

On 1 July 2016, the Navy submitted a funding plan for its 36 billion baht submarine procurement project to the cabinet for consideration with the expenditure to be spread over 11 years.

The first submarine would be bought for 13 billion baht between fiscal years 2017–2021. The second and third submarines would be purchased during the remainder of the 11-year period.

The Royal Thai Navy and the Thai Government signed a contract for one S26T variant of the submarine in a $390 million deal. Orders for an additional two submarines are expected in the coming years. Steel cutting ceremony of the first S26T submarine was held on 4 September 2018 in Wuhan, China.

However, problems arose when Germany blocked the export of the engines it was to supply. Since then, the program has been at a standstill. Thailand threatened to cancel the program and China proposed indigenous engines instead of German ones.
