480:. Daily operations of the aerostat would augment existing intelligence, surveillance, and reconnaissance (ISR) capability of the PN though its payloads such as automatic identification system, Digital Global Positioning System (DGPS), radar, and communications equipment. Its initial concept is a mobile Littoral Monitoring Station (LMS). As such, it is used to effectively monitor maritime and air traffic in the area which cannot be covered by the existing LMS-Zambales, thereby achieving maritime situational awareness. One unique capability of the aerostat is that it can provide a persistent long-range coastal surveillance for up to 128 nautical miles at 4,000 feet elevation based on actual flight done by the aerostat students. It has the capability to be launched continuously for a week by just ensuring sufficiency of the helium content. As an LMS, the information gathered from the aerostat is sent to the Maritime Research and Information Center (MRIC), Naval Operations Center (NOC), Naval Forces Northern Luzon (NFNL), Naval Forces Operation Center (NFOC), and other PN units/stakeholders needing the information. Other possible operational use of the aerostat includes a platform for communications, monitoring system for humanitarian and disaster response, and other surveillance purposes.

The hull of the aerostat contains two parts separated by a gas-tight fabric partition. The upper chamber is filled with helium and provides the aerostat's lifting capability. The lower chamber of the hull is a pressurized air compartment. The hull is constructed of a lightweight polyurethane-coated

Operators launch the aerostat from a large circular launch pad containing a mooring fixed or mobile system. The mooring systems contain a large winch with 25,000 feet (7,600 m) of tether cable. Operational availability is generally limited only by the weather (60 percent standard) and routine

Under Air Force management, through contract consolidation and system standardization, the operations and maintenance cost per site was reduced from $ 6 million in fiscal year 1992 to $ 3.5 million in 2007.
