ADASI: AEROSTAT

The Aerostat Systems are designed to be operated by a team of three and can operate continuously for 5 days without helium replenishment.
The Aerostats Systems in the family will be:
1. A-150. First to be tested in the spring of 2012, this 150m3 aerostat, approximately 13m long, is capable of low altitude operations (up to 1,000ft) carrying a banner set or a custom appliqué logo for commercial use or a single EO/IR payload, such as a Wescam MX-10, for government applications.
2. A-400. Following in early 2013, this aerostat will be based closely on the AD-150. A larger system (400m3 and approximately 19m long), the AD-400 will be capable of operating at up to 2,000ft carrying a more substantial EO/IR payload, such as a FLIR Systems Star SAFIRE III, or a small radar system, such as a Selex Galileo Gabbiano X-Band system.
3. A-700. The largest aerostat in the family at 700m3 and approximately 23m long, this aerostat will be capable of operating at up to 3,500ft. It is specifically targeted at meeting requirements for aerostats to be operated from locations that are above sea level. Furthermore, unlike its smaller family members, the AD-700 will be capable of carrying dual mission systems, comprising a combination of any two EO/IR systems, radio relay packages, radar systems or passive EW packages.

Lockheed’s aerostat is the best out there. IMO.
