Airships return for future Aviation, Intelligence, Surveillance, Reconnaissance, and cruise missile defense.

Airship is a type of lighter-than-air aircraft which can navigate through the air under its own power. They are different from  Aerostats that gain their lift from large gas bags filled with a lifting gas that is less dense than the surrounding air.  Historically, airships have been used in applications where the ability to hover in one place for an extended period outweighs the need for speed and maneuverability.
