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.
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 ...
In May 2011, Goodyear announced that they would replace their fleet of blimps with Zeppelin NTs, [133] [134] resurrecting their partnership that ended over 70 years ago. Goodyear placed an order for three Zeppelin NTs, which then entered service between 2014 and 2018.

The initials LZ, for Luftschiff Zeppelin (German for "Zeppelin airship"), usually prefixed their craft's serial identifiers. Streamlined rigid (or semi-rigid) [ 25 ] airships are often referred to as "Zeppelins", because of the fame that this company acquired due to the number of airships it produced, [ 26 ] [ 27 ] although its early rival was ...
The helium-filled blimps are fitted with solar panels and backup batteries to power their engines, have a flight time of up to 12 hours and a range of up to 400 kilometers (249 miles), flying at a ...
Zeppelin NT D-LZZR at the airport in Friedrichshafen, 2003. The Zeppelin NT series are a family of semi-rigid airships, combining the design principles of rigid airships and blimps together. [7] The Zeppelin N07, the base model and most commonly constructed to date, are 75 metres (246 ft) long, with a volume of 8,225 cubic metres (290,500 cu ft).
More than 2,500 miles away from Akron in Silicon Valley, what engineers say is the world's largest airship took flight for the first time. This massive snow-white zeppelin-like ship is slated to ...
