"OK. Barrage balloons. Which actually make a lot of sense, I'm surprised nobody else has thought of it."
Dr. Rodney McKay[src]

Barrage balloons are Levannan air defensive technology.

Overview[]

The technology features a series of balloons that lift up cables and are tethered to towers and rooftops to interfere with Wraith darts.

The balloons themselves are made of impermeable silk, a heavy cloth similar to rubber. The seams, connections, and valves are triple stitched and coated inside and out with the same material. They are then filled with a special acid, (stronger than scrap iron, and sulfuric acid and in a shorter amount of time), that produces hydrogen gas.

The barrage balloons can lift about 9 kilograms of rope, chain, or wire. (SGA: "Legacy: Homecoming")

History[]

2009[]

In 2009, Dr. Rodney McKay was able to help solve a problem with the device's exothermic reaction when filling the balloons. The barrage balloons were then used against Queen Death's forces in the Battle of Levanna. (SGA: "Legacy: Homecoming")
