Aerostationthe art or science of operating lighter-than-air craft
Balloon Wars: An ISR Operator’s Account of the Wars in Iraq and Afghanistan is the account of those periods.
Kite balloons were used in World War I as observation platforms and in the Second World War they were floated over harbors and beach heads to hinder enemy aircraft. Those were “Barrage Balloons”. Since then they have been used to support radar, telescopes, cameras, communications and other highly technical payloads. I’ve worked on three programs that used them. The “Kite Balloons” page on this site is about two of those programs, the Tethered Aerostat Radar System (TARS) and the Sea Based Aerostat System (SBAS).
