Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.

Unlike semi-rigid and rigid airships (e.g. Zeppelins), blimps rely on the pressure of their lifting gas (usually helium, rather than flammable hydrogen) and the strength of the envelope to maintain their shape. Blimps are known for their use in advertising, surveillance, and observation due to their maneuverability, slow speeds and steady flight capabilities.

The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS (colloquially, Spy Balloon), was a tethered aerial detection system designed to track boats, ground vehicles, cruise missiles, manned and unmanned aircraft (airborne early warning and control), and other threats. The system had four primary components: two tethered aerostats which utilized a helium/air mix, armored mooring stations, sophisticated radars, and a processing station designed to communicate with anti-missile and other ground and airborne systems. Each system was referred to as an "orbit", and two o
