Hosted by the RTN, the exercise will run up to 30 March this year.
An opening ceremony co-officiated by RSN fleet commander rear admiral Saw Shi Tat and RTN fleet commander-in-chief admiral Suvin Jangyodsuk was held at Changi Naval Base on 21 March.
Saw Shi Tat said: “This exercise is a cornerstone of our bilateral relations.
“Both our navies have derived good value from exercising together and this is an opportunity for our officers and sailors to build friendship, mutual understanding and interoperability.”
Exercise Singsiam 2022 involves the participation of the RTN’s S-76B naval helicopter, along with the Naresuan-class frigate HTMS Naresuan and the Chao Phraya-class frigate HTMS Saiburi.
In addition, the RSN’s warships that are taking part include the Formidable-class frigate RSS Formidable, aboard S-70B naval helicopter, the Victory-class missile corvette RSS Valiant, and the Independence-class littoral mission vessel RSS Fortitude.
During the sea phase of the exercise, the RSN and the RTN navies conducted a range of conventional warfare and maritime training in the Malacca Strait and the Andaman Sea.
The training included maritime surveillance, gunnery firings, communication drills and manoeuvring serials.
This year’s edition of Exercise Singsiam also witnessed some advanced naval serials with increased complex scenarios.
The regular interactions between both navies aim to strengthen close and long-standing defence ties between Thailand and Singapore.
Apart from Exercise Singsiam, the navies also conduct a range of activities and professional exchange courses to strengthen cooperation.
The RTN and RSN also take part in combined missile-firing exercises and maritime security operations.
