The Royal Thai Navy has officially received the new survey and hydrographic vessel, Suriyas, at Pom Suea Son Lap Pier, Naval Academy, Samut Prakan, on 30 March 2026. The ship, constructed by Thai engineers to international standards, will enhance the navy’s capabilities in deep-sea exploration and maritime operations. Admiral Phairoj Fuangchan, Commander-in-Chief of the Royal Thai Navy, presided over the handover ceremony and addressed the crew assigned to the vessel.

The new Suriyas replaces the older vessel of the same name, which is scheduled for decommissioning. The navy commissioned one unit through Asian Marine Services Public Company Limited to support hydrographic and oceanographic missions. The 60-metre vessel has a displacement of 1,460 tonnes, can operate in sea conditions with waves up to level 5 conditions and sustain non-stop operational missions for at least 10 days, with a travel range of up to 2,400 nautical miles and accommodates 67 personnel.

Suriyas’ primary mission includes surveying and collecting hydrographic and oceanographic data, which are vital for safe navigation and national maritime security. The ship can also maintain and repair navigational markers, transport supplies to coastal and offshore units, provide assistance in maritime emergencies and carry out other assignments as directed by the navy. The vessel is expected to strengthen the navy’s operational capacity while supporting the development of Thailand’s domestic shipbuilding industry.

Experts note that commissioning Suriyas marks a significant step in enhancing Thailand’s maritime research and operational infrastructure. By using locally built vessels, the navy aims to sustain technological expertise and promote long-term growth in the national shipbuilding sector. The handover reflects both a strategic investment in maritime capabilities and a commitment to advancing domestic industry.

Amarin reported that Suriyas will immediately begin operational deployment under the Hydrographic Department of the Royal Thai Navy. The ship will participate in a range of missions, from data collection for scientific research to logistical support for naval units, contributing to Thailand’s maritime security and exploration efforts in national waters.

Will it prove that Thailand's need for submarines is merely toys-for-the-boys?

As someone who spent over 20 years serving on research and survey vessels, I can say without hesitation that ships like Suriyas play a far more important role than most people ever realise.

They become more than just platforms for work, they become your second home, and the crew becomes like family, forged by long days, bad weather, and the shared purpose of gathering data that keeps mariners safe.

Seeing the Royal Thai Navy take delivery of a new Thai‑built survey ship is genuinely encouraging. That kind of investment pays dividends for decades, not only in safer navigation but also in strengthening the country’s own shipbuilding and technical expertise.

To get new crew: may she serve you well. There’s nothing quite like the pride of bringing a new vessel into service and shaping her future.

Here’s hoping Suriyas has a long, productive, and distinguished career ahead of her. India Romeo!
