The Singapore and Thai navies are conducting a bilateral naval exercise Singsiam from Tuesday till the 20th of this month.

The Defence Ministry says the exercise is the fourteenth in the series between the two navies.

It will have a sea phase and two shore phases to be conducted at Changi Naval Base and Sattahip Naval Base in Thailand.

Since it started in 1981, the biennial exercise has expanded in scope and complexity over the years, evolving from conventional naval warfare exercises to incorporating maritime security exercises.

This year's drill will also have maritime surveillance and tracking for the first time.
