Since many authors don't go through the trouble to clarify their airship as either a blimp or zeppelin, it makes no sense to separate them here.
If an airship is made from a single flight deck/cabin stuck directly to the gasbag, it belongs here.

If it has multiple decks it goes to Large Rigid Airships instead.

If the cabin is hanging freely under the gasbag, it belongs to Gasbag Suspended Boats instead.
