 The Royal Malaysian Navy has maintained an "offshore naval station" on the island since 1983, and CB90 assault craft based in the station patrol the surrounding waters.Several anti-ship and anti-aircraft guns are placed around the reef, and the personnel operate a Starburst air defence system to prevent low level attacks on the island.The jetty is located inside the lagoon of the submerged atoll, and has access to the sea through a man-made path cleared of corals.
