The Philippine Navy (PN) will soon be sending Engineers to Fuga Island in Cagayan to determine the best locations for its Naval Detachment and other Facilities.
The Facilities will include a Littoral Monitoring Station (LMS) that ideally should be placed on the highest point of the Island. The LMS will have Radars and Electro-Optical Devices that will allow it to monitor Ships up to 39 km out.
It will also have Radio Equipment for Communications and will be manned by the PN 24/7.
