The Thai Navy’s long-awaited acquisition of a Yuan-class S26T submarine remains uncertain as Defence Minister Phumtham Wechayachai announced that a comprehensive viability study is still in progress. Valued at 12.4 billion Thai Baht, the project has faced delays due to engine supply issues, now requiring the use of a Chinese-made CHD620 engine instead of the originally planned German MTU396 engine.
This decision-making process underscores ongoing challenges for Thailand’s first submarine purchase in over 60 years. Amendments to the initial contract to accommodate the engine switch have added further complexity, with the navy emphasizing the strategic importance of the project.
Minister Phumtham, newly appointed to his position, stressed the need for a careful review to ensure the procurement aligns with Thailand’s long-term interests. His approach reflects caution, marking a departure from his predecessor Sutin Khlangsang, who had previously suggested pivoting to a frigate instead.
The navy remains committed to the submarine project, rejecting alternatives as it considers the S26T vital for advancing Thailand’s naval capabilities. However, the ongoing delay has raised questions about broader strategic considerations, including the growing ties between Thailand and China in military technology.
With implications for both national defence and international relations, the outcome of the feasibility study will shape Thailand’s naval strategy for years to come.
