- A draken balloon.
- A flying ship such as the Uraeus and the Papal Emissary Ship.
- A lighter-than-air aircraft that can be steered and propelled through the air. It depends on aerostatic lift rather than aerodynamic motion to remain aloft and has a rigid frames containing multiple, non-pressurized gas cells or balloons to provide lift.
In modern common usage, the terms zeppelin and airship are used interchangeably for any type of rigid airship.
Airship technology is based on the earlier draken and the example of the airships used by the Ice Lords in the Ice War. The term zeppelin derives from Count von Zeppelin, an early pioneer in the Danish Empire working from a wrecked Ice Lord craft. Even before the Ice War draken relying on both hot air and hydrogen were in common use. The greatest technological challenges were the means of propelling and steering the airship. Recovered Ithaqua-Sanrio kerosene engines were copied with varying success. The kerosene fuel is distilled from coal and shale.
It took several years of development and trial and error for viable airships to be constructed, and even after several decades the vehicles remain inferior to those used by the Ice Lords and other cultic groups. The primary lifting gas remains hydrogen save in those nations having access to helium. Hydrogen is comparatively easy to obtain but is flammable when mixed with air.
The copies made of Ice Lord airship remain inferior in both altitude and speed. It was discovered in 1763 that a Polytechnic League airship utilised some form of magic to enhance its capabilities. For non-cultic researchers the development of a true Internal Combustion Engine burning better grades of fuel than kerosene offers the potential for faster airships.
As a result of parallel development airship design varies across the globe. The basic rigid envelope is a constant although its configuration may vary.
- A Frost Wolf airship as reported during the Ice War is shown above. Note the gun cupolas.
- European airships tend to a cigar shape with the command gondola and engine cars slung below. Danish airships adopt a gray-black color scheme, whilst ARF vessels are gray.
- Some Javan airships have a double hull with the gondola depending from the spars between them. The fins are often extravagant and brightly decorated and various types of bamboo and grades of silk are utilized. The Javan Empire often employs a blue color scheme.
- Nisei airships are frequently highly decorated with traditional designs. Early Nisei airships had a blunt nose that could be used as a ram.
- Early Aztec airship – note the traditional Méxica Sun motif.
- Javan dragonship.
- Aeronautical Research & Fabrication Raptor-class airship.
- Albanian East India Company flying casino.
- Norsk Aer passenger and light cargo airship.
- Invader Manta - exact size uncertain
