A Zeppelin was a type of rigid airship named after the German Count Ferdinand von Zeppelin used by the German Empire during World War I. Zeppelins are featured in the Call of Duty: Black Ops II, Call of Duty: Black Ops III and Call of Duty: WWII.

A very brief appearance is also made in Der Eisendrache, where one variant of posters scattered within the map features a Zeppelin appearing in the sky, above what appears to be the city beneath the castle.

In the Nazi Zombies map The Final Reich, A Zeppelin airship used by Heinz Richter is seen during both the casual and hardcore quests. The Panzermörder destroys the Zeppelin after it is defeated by the player.
In The Resistance DLC map The Darkest Shore, Zeppelins used by Peter Straub's army are seen during the ending cinematic of the main quest. The Zeppelins also play a major role in the Nazi Zombies chapter The Shadowed Throne.
