SINGAPORE: A suspicious vessel has been detected in Singapore waters, and a Republic of Singapore Navy (RSN) vessel on patrol races alongside to intercept it, sirens blaring, with voice commands over the loudspeakers ordering the suspect vessel to stop.
But there is no one on board the RSN vessel – a new maritime security unmanned surface vessel (Marsec USV) that began patrolling Singapore waters in 2025.
