In peacetime, this mission involves keeping a sharp eye and maintaining continuous surveillance on the Singapore Strait, forming a vanguard against sea robberies, piracy, terrorism and unwanted incursions.

In wartime, the RSN will work to secure a swift and decisive victory over any enemy at sea.
But we are not just a fighting force; we are a diplomatic one as well. We sail across the seas, exercising with other navies and visit foreign ports. We take part in international operations for peace support, humanitarian assistance and disaster relief. By co-operating with like-minded nations and being a responsible member of the international community, the RSN is able to not just defend our nation’s every day, but also the world’s every day.
