Iraq
The aerostats (tethered blimps) float at about 300 meters (a thousand feet) up, tethered by a cable
Shorter steel tower systems also suffer gunfire damage, but rarely any that damages the equipment. It was soon found that tower mounted cameras were just as good as the aerostats, in most situation, and much cheaper. Thus there are more than twenty times as many tower systems as aerostat based ones in use.
In Iraq and Afghanistan the towers were introduced in 2003 and the aerostats a year later. The U.S. would set up the towers even for temporary bases. The tower provides the equivalent of a permanent UAV presence, which, just by being there, tends to discourage attacks, or any misbehavior in the vicinity of the base. The tallest tower is 32 meters (107 feet) tall allowing cameras to spot vehicles up to 25 kilometers away. Great for keeping an eye on thinly populated areas in a desert, which western Iraq has plenty of. The nine meter (30 foot) tower can see out to eleven kilometers, the 18 meter (60 foot) tower out to 16 kilometers and 25.5 meter (84 foot) tower out to 20 kilometers. The nine meter tower was adequate for most situations, which usually involved guarding a base, but the taller towers also served as a communications relay for widely dispersed troops. The towers were designed to be easily taken apart or erected by troops.
Before leaving Iraq the U.S. developed and installed several upgrades to the sensors and software used in the aerostats and towers. The best of these was a system that combined communications and electronic eavesdropping gear and software, with day/night camera towers, to produce BETSS-C (Base Expeditionary Targeting and Surveillance Sensors-Combined). These systems also contain a laser range finder and designator.
The U.S. Army also installed AN/ZPY-1 Starlite lightweight radars in some aerostats. This combination was very popular in Afghanistan. The Starlite radar weighs 29.5 kg (65 pounds), occupies 34 cc (1.2 cubic feet), uses 750 watts of power and costs about $2.3 million each. The Starlite was originally designed for use in the army's new 1.5 ton MQ-1C Sky Warrior UAV. Starlite can deliver photo quality
It is unclear exactly which sensors, and supporting software, the Iraqis will be allowed to buy. Given the heavy influence of Iran inside Iraq it has to be assumed that any military equipment sold to Iraq will be examined by the Iranians.
