Aerostats Rise Through the Ranks in Surveillance Service
Aerostats are carving a substantial niche in the airborne surveillance business.
This 590,000-cu-ft aerostat is the largest yet flown for a military surveillance mission. It was fabricated by TCOM for the Raytheon JLENS development program. Like similar radar-carrying aerostats, the sensor is housed in a separate, pressurized compartment below the main envelope. (credit: Raytheon).
