Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.
Blimps are non-rigid airships. Their shape is determined by the design of the envelope (inflatable bag). Most common airships are shaped like a cigar.
The most famous airships are Hendenburg and Zeppelin.
Hydrogen airships can vary in size, but most commercial airships are around 200 to 250 feet in length. However, historical airships like the Hindenburg were much larger, at approximately 800 feet long.
Blimps are non-rigid airships with an envelope that maintains their shape, while dirigibles are semi-rigid or rigid airships with a structure inside the envelope to maintain their shape. Dirigibles are typically larger and have more internal structure for support and control.
Airships do use gas, to provide lift.
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.

Hydrogen used to be used in airships.
Curly's Airships was created on 2000-10-05.
The type of airship with a metal frame that extends the entire length and height of the envelope is known as a rigid airship. Unlike non-rigid airships, which rely on internal gas pressure to maintain their shape, rigid airships have a structural framework that supports the envelope and maintains its form. This design allows for greater control and stability in flight, as well as the ability to carry heavier payloads. The most famous examples of rigid airships include the Zeppelin and the Graf Zeppelin.
gas is still used in airships to provide lift.
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
