2.5.1 Advanced Airship Flying Laboratory
User Service: Navy Manufacturer: American Blimp Corporation Inventory: 0 Delivered/1 Planned
Background: The Advanced Airship Flying Laboratory (AAFL) will serve as a prototype test bed for improving the state-of-the-art of airship systems technologies, ISR sensors, related processors, and communications networks. The initial airship systems to be developed and tested will be bow thrusters for slow speed control authority to reduce ground crew requirements; heavy fuel engines to increase efficiency, safety, and military operations interoperability; and automated flight controls to increase payload, altitude, and reduce flight operations costs. AAFL will be equipped with dedicated hard points, equipment racks, high bandwidth network interfaces, and 5 kW of power for rapid integration to test a great variety of Network Centric Warfare payload options from a persistent ISR platform.

2.5.2 Tethered Aerostat Radar System (TARS)
User Service: Air Force Manufacturer: ILC Dover Inventory: 10 Delivered/10 Planned Background: TARS primary mission is to provide low level radar surveillance data in support of federal agencies involved in the nation’s drug interdiction program. Its secondary mission is to provide North America Aerospace Defense Command with low level surveillance coverage for air sovereignty in the Florida Straights. One aerostat, located at Cudjoe Key, FL, transmits T V Marti, which sends American television signals to Cuba for the Office of Cuba broadcasting. All radar data is transmitted to a ground station, then digitized and fed to the various users. Airborne time is generally limited by the weather to 60 percent operational availability; notwithstanding weather, aerostat and equipment availability averages more than 98 percent system wide. For security and safety reasons, the air space around USAF aerostat sites is restricted for a radius of at least two to three statute miles and an altitude up to 15,000 feet. http://www2.acc.af.mil/library/factsheets/tars.html.

2.5.3 Joint Land Attack Elevated Netted Sensor (JLENS)
User Service: Joint (Army Lead) Manufacturer: Raytheon/TCOM Inventory: 12 Planned Background: JLENS is primarily intended to tackle the growing threat of cruise missiles to U.S. forces deployed abroad with radars to provide over-the-horizon surveillance. A JLENS system consists of two aerostats, one containing a surveillance radar (SuR) and one containing a precision track illumination radar (PTIR). Each aerostat is tethered to a mobile mooring station and attached to a processing station via a fiber optic/power tether. The SuR provides the initial target detection and t hen cueing to the PTIR, which generates a fire control quality track. The JLENS system is integrated into th e joint tactical architecture via Link 16, cooperative engagement capability, single-channel ground and air radio system, and enhanced position location reporting system. Both radar systems will include identification, friend or foe interrogators.
