Speaking of Hindenburg, this is my largest airship:

It's 500m long so about 8 times larger.
Used to be filled with Helium but nowadays it lifts with Kavuria whenever it's actually justified for the mission.

There's also a commercial version of this on sale with 95% less guns, half the engine power, no internal runaway pad and better cargo capacity (since armor and guns don't weight it down).
If weren't for the fact it's a bit too expensive to buy, it could almost replace water-based ships for transporting goods.
... That and overtly eager AA crews potentially mistaking it for a warship from Yllendthyr.:lol
