Construction of USS Shenandoah, 1923, showing the framework of a rigid airship. A rigid airship is a type of airship (or dirigible) in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships.
USS Shenandoah was the first of four United States Navy rigid airships. It was constructed during 1922–1923 at Lakehurst Naval Air Station, and first flew in September 1923. It developed the U.S. Navy's experience with rigid airships and made the first crossing of North America by airship.

In contrast to the Zeppelins, the Parsevals were non-rigid or semi-rigid airships, with little or no stiffening structure inside the fabric envelope. The Zeppelins had a rigid internal framework made of duralumin. Both types relied on hydrogen gas to provide lift. Diagram of an early Parseval airship.
The main types of airship are non-rigid, semi-rigid and rigid airships. [3] Non-rigid airships, often called "blimps", rely solely on internal gas pressure to maintain the envelope shape. Semi-rigid airships maintain their shape by internal pressure, but have some form of supporting structure, such as a fixed keel, attached to it.

The AEREON III was an experimental hybrid airship of rigid construction built by the AEREON Corporation in the early 1960s. Of unconventional design, the airship featured three gas envelopes attached side-by-side, with the connecting structures shaped as airfoils to create extra lift as the craft moved forward.
USS Los Angeles was a rigid airship, designated ZR-3, which was built in 1923–1924 by the Zeppelin company in Friedrichshafen, Germany, as war reparations.She was delivered to the United States Navy in October 1924 and after being used mainly for experimental work, particularly in the development of the American parasite fighter program, was decommissioned in 1932.
