Trireme Airship

Named after the surface ship with three rows of oars, the trireme is essentially a flying casemate ironclad. In fact, the hull is a squashed version of a Tiamarda hull, with tighter curves in the cross-section that lend extra strength to the frame.  Few and far between were airships more powerful than this.  Developed from the same basic design of Argo and Talos, this plainer version has neither figurehead nor spacious accomodations for officers and distinguished guests, but instead has a much more practical layout.
